The Shaken Baby Syndrome Myth renamed "Abusive Head Trauma" or "Non-Accidental Injury"

"MYTH" WEBSITE SUMMARY SUBJECT: RETINAL HEMORRHAGES, UNPROVEN SBS DIAGNOSTIC SIGNS Retinal Hemorrhage Study (separate page) Shaken
Baby Syndrome: Retinal Hemorrhages
Medical
Dogma Without Supporting Science The medical assumptions used as guidelines are "equal to a fall from a 2-story building or being unrestrained in a vehicle accident". So, if the caretaker can't provide documented evidence that the infant fell out of a window, was in an accident, or was videotaped or observed suffering from an accident this severe by an unrelated "reliable" witness, then the symptoms are assumed to be caused by child abuse no matter what the caretaker says, including cases where the symptoms came on after a vaccination, the infant was found in a crib or bassinet unresponsive with no external sign of trauma, fell or was dropped from a short distance, and there was no history of abusive behavior or the expectation that the accused would harm an infant. "Abusive"
or "Non-accidental" head trauma is usually assumed where
accidental trauma remains undocumented. Even though emergency pediatric
physicians are instructed to consider Differential Diagnosis (other
causes of the same symptoms) in these cases, other causes are rarely
even considered and almost never tested for to eliminate medical causes,
which results in RH being put into two categories: At present there are no reliably witnessed cases of shaking which have produced the symptoms associated with Shaken Baby Syndrome/Abusive Head Trauma. There have, however, been documented cases of shaking which produced no injury. http://www.aao.org/aao/news/eyenet/pediatrics/pediatrics_jul.htm Pediatrics It is a scenario that occurs every day in ERs across the country. Paramedics or parents rush in a child who is not breathing, lethargic, comatose or experiencing seizures. The trauma team, after examining the baby, calls in the attending ophthalmologist to confirm what they may suspect: shaken baby syndrome, the leading cause of death in child abuse cases in the United States. Why
is the expertise of an ophthalmologist so sought after? Because retinal
hemorrhages are a telltale sign of SBS. Ophthalmic expertise is necessary
to make a diagnosis; moreover, accurate documentation may prove vital
evidence in a court of law. “Shaken baby syndrome” has evolved into “shaken impact baby syndrome” because in many cases, the child is shaken and then thrown, said Sean P. Donahue, MD, associate professor of ophthalmology, pediatrics and neurology at Vanderbilt University. Cerebral damage caused by the impact of hitting an immobile object is also afeature of SBS—and in fact, the syndrome is characterized by symptoms that include brain swelling (see “Who, Where, What and Why”). Differential
Diagnosis One of the striking things about retinal hemorrhage and SBS is that this clinical sign in toddlers is relatively unusual. The differential diagnosis for retinal hemorrhage in this age group includes leukemia, low blood platelets and clotting disorders, said Dr. Repka. Dr. Donahue added, “Other problems can cause retinal hemorrhages, but those are typically very different and the underlying clinical setting is also different. History and clinical examination, along with the retinal hemorrhage, helps in making the SBS diagnosis.” Conversely, he said, the absence of retinal hemorrhages does not exclude the diagnosis of SBS. Yet the presence of retinal hemorrhage in a suspicious situation makes the diagnosis very likely. In the famous case of the British nanny and the death of Matthew Eappen One
Ophthalmologist’s Story Matthew’s mother, Deborah S. Eappen, MD, is an ophthalmologist practicing with Harvard Vanguard Medical Associates in Boston. This tragic experience has prompted her to start a foundation for her son (http://www.mattyeappen.org) and to speak across the country about diagnosing SBS and documenting the clinical findings. She spoke to her Academy colleagues at the Mid-Year Forum in Washington, D.C., this spring, and one literally could hear a pin drop as she told her story. Dr. Eappen notes that she does not remember actually learning about SBS during her residency at Tufts University in the early 1990s. “It simply wasn’t a topic that was taught. In fact, while there is more awareness about SBS today, it still represents a taboo subject, and oftentimes physicians would rather find some other explanation for retinal hemorrhage than child abuse. However, this retinal hemorrhage is distinctive—not even severe motor vehicle accidents cause this type of bleeding.” Documentation
Is Essential Dr. Eappen added that ophthalmologists have a responsibility to write not just “retinal hemorrhage” on their reports but the diagnosis of SBS (if it is suspected). “Think about it,” she told the Mid-Year Forum meeting attendees: “If we see diabetic retinopathy, we don’t write ‘retinal hemorrhage.’ We name the underlying cause. And when we see retinal hemorrhage as part of SBS, we need to call it what it is.” Dr. Donahue also pointed out the importance of documenting the extent and location of the retinal hemorrhages, with photography if possible. Ophthalmologists also may be subpoenaed to testify in these cases. He advised, “Make sure you work with child abuse experts in your medical center, who can help incorporate additional findings of the examination and look for other indicators of trauma and abuse.” Dr. Mills emphasized, “Ophthalmologists can’t just walk away from these children after the diagnosis and documentation. They will need long-term follow-up care and may require low-vision evaluations, treatment for amblyopia or vitreous surgery.” Dr. Eappen called for the Academy to treat SBS as it does any other life-threatening diagnosis. “We need enhanced education, specific documentation and access to relevant pediatric literature. As ophthalmologists, we must all be able to provide optimal care for our most vulnerable patients—our babies. If we miss SBS once, we may not get another chance.” (One of the pathologists who testified for the prosecution in this case has since reversed his opinion and stated that he couldn't say how the baby died. And the nanny stated under oath that she did not shake or slam the baby down, but rather found him unresponsive in his crib. This happened at age 81/2 months, which probably meant he was vaccinated at an 8 months, and this would fall within the time frame of the known 28 day period following vaccination that extreme and sometimes fatal adverse events take place.) http://www.cnn.com/US/9710/23/nanny.trial/index.html Retinal
Hemorrhages have other causes False
Assumption Truth: Prosecutors and proponents of Shaken Baby Syndrome assert that retinal hemorrhages are pathognomonic for (i.e. diagnostic of) Shaken Baby Syndrome. In fact, retinal hemorrhages are found in a myriad of different conditions, most of which result in a sudden increase in intracranial pressure. A human head is a closed space, with limited spare room for things like bleeding and swelling. Therefore, when the brain has reached its cranial capacity, but is still increasing in mass, it becomes compressed and pushes down toward the only escape route- the foramen magnum. The mechanisms behind the respiratory arrest or death in "SBS" cases are also the result of increased intracranial pressure.

witnessed 3-foot fall out of father's arms as he was lying in bed;
acute right epidermal hemorrhage and skull fracture; right single
intra retinal hemorrhage We appreciate the controversy that exists regarding the diagnosis of abusive head injury in young infants to which Dr Lueder alludes. It is important to note that in the cases of accidental head injury that were accompanied by retinal hemorrhages, there was a clear history of head trauma that was given by the caregivers when the child first presented for care. It is also noteworthy that the types of retinal hemorrhages present in children with accidental head injury were distinctly different from those present in children with abusive head injury in that they were confined to the intraretinal layer, did not cover the macula, and did not extend to the periphery of the retina.* We hope that our study serves to clarify some of the clinical issues that are raised when evaluating young children with head trauma.
REFERENCE http://pediatrics.aappublications.org/cgi/content/abstract/85/4/585 1 Department of Pediatrics, Henry Ford Hospital, Detroit, Michigan Retinal hemorrhage detected after cardiopulmonary resuscitation has important medical, social, and legal implications. When a child is brought to the hospital in circulatory arrest, these hemorrhages raise the question of preceding trauma, frequently child abuse.1 Several authors have suggested that retinal hemorrhage may be virtually pathognomonic of child abuse.2,3 We have questioned this belief because our experience, as well as that of others,4,5 suggests that retinal hemorrhage may result from resuscitative efforts. We therefore undertook a prospective study to evaluate whether cardiopulmonary resuscitation can cause retinal hemorrhage. MATERIALS AND METHODS During a 4-month period, all children admitted to the Pediatric Critical Care Medicine Service who underwent cardiopulmonary resuscitation were considered for inclusion in the study. http://www.ncbi.nlm.nih.gov/sites Department of Pathology, University of Texas Medical Branch, Galveston 77550. Unexplained retinal hemorrhages in infants are usually indicative of child abuse. We present the case of an infant with retinal hemorrhages following cardiopulmonary resuscitation, who had not been abused. Cardiopulmonary resuscitation should be added to the list of causes of retinal hemorrhages in infants and children.

hemorrhage in the young child: a review of etiology, predisposed conditions,
and clinical implications http://www.greenjournal.org/cgi/content/abstract/81/5/688 OBJECTIVE: To determine whether maternal or fetal factors, other than vacuum-assisted delivery, play a role in neonatal retinal hemorrhage, and whether correlates are similar in retinal hemorrhage after spontaneous vaginal delivery. METHODS: A cross-section of assisted deliveries at an urban hospital (n = 156) over 7 months were compared with contemporaneous spontaneous vaginal deliveries (n = 122). A subset of assisted deliveries (n = 87) was prospectively randomized to forceps or vacuum-assisted delivery by sealed envelope. Maternal and neonatal biometric data were collected, and Apgar scores, umbilical artery blood gas analysis, and neonatal ophthalmologic evaluations were performed. RESULTS: Moderate to severe retinal hemorrhage was found in 18% of spontaneous, 13% of forceps, 28% of vacuum-assisted, and 50% of sequential vacuum and forceps-assisted deliveries. Fetal distress (P < .008), vacuum-assisted delivery (P < .02), decreased birth weight for gestation (P < .004), umbilical artery pH less than 7.20 (P < .004), and second stage of labor less than 30 minutes (P < .05) were most closely associated with increased degrees of retinal hemorrhage. Maternal parity, preeclampsia, length of labor, and head circumference were not correlated with retinal hemorrhage. Vacuum-assisted delivery among low birth weight infants (P < .0001), short second stage of labor (P < .006), fetal acidosis (P < .045), and sequential use of vacuum and forceps for assisted delivery (P < .005) formed a logistic model that correctly predicted 81% of moderate to severe retinal hemorrhage cases. Logistic analysis of the randomized assisted deliveries gave similar results. CONCLUSIONS: Maternal and fetal factors other than vacuum-assisted delivery are significant correlates of moderate to severe retinal hemorrhage. Vacuum-assisted delivery among small for gestational age infants is closely correlated with moderate to severe retinal hemorrhage. S. Herr,

One child was a two-year-old victim of an accidental drowning, and the other was a six-week-old diagnosed with sudden infant death syndrome. Skeletal survey and autopsy ruled out trauma in both cases. The authors also report a nine-year-old boy who had two cardiac arrests caused by asthma. There were no retinal hemorrhages after these episodes, but two hemorrhages were detected after a third resuscitation. The
mechanism of retinal hemorrhage is believed to be increased intrathoracic
pressure caused by chest compression during resuscitation attempts,
which in turn increases retinal venous pressure. Child abuse must
always be suspected in a child with cardiopulmonary arrest and retinal
hemorrhage, but it must be remembered that abuse is not the only cause.—

The ocular lesions often appeared early in the development of clinical scurvy and were first noted after deprivation of ascorbic acid for 74-95 days. These lesions varied from minute bulbar conjunctival hemorrhages and varicosities to a large subconjunctival hemorrhage accompanied by palpebral petechial hemorrhages, and conjunctival congestion. http://www.jpands.org/vol11no1/clemetson.pdf http://www.blackwell-synergy.com/doi/abs/10.1111/j.1365-4632.2007.02856.x?journalCode=ijd

Here we have the medical establishment debating its very existance.) http://www.cincinnatichildrens.org/svc/alpha/c/child-buse/tools/retinal-hemorrhage.htm Review of Retinal Hemorrhages Authored by Kathi Makoroff, M.D. The Child Abuse and Neglect Team of The Mayerson Center for Safe and Healthy Children at Cincinnati Children's Hospital provides the following clinical update of literature on retinal hemorrhages resulting from shaken baby syndrome. Does
Accidental Injury Result in Retinal Hemorrhages? Combining the three studies, a total of 215 children were examined. Two children (0.93%) had retinal hemorrhages; both of these children were involved in fatal or serious motor vehicle accidents. Buys, et al. and Duhaime, et al. examined children who sustained traumatic head injury. Buys found that 3/78 children had retinal hemorrhages; all three children were determined to have suffered non-accidental head injury after full multidisciplinary work-up. Duhaime found retinal hemorrhages in 10/100 patients <24 months who were admitted with head injury. Nine patients with retinal hemorrhages were felt by the authors to have suffered abusive head trauma. The other patient with retinal hemorrhages was involved in a motor vehicle accident. Luerssen, et al. examined a database of 811 pediatric patients who were admitted to the hospital following traumatic brain injury. Retinal hemorrhages were detected in 27 patients. Twenty-two of these patients were felt by the authors to have suffered abusive head injury; one patient was involved in a motor vehicle accident and four patients suffered falls. Christian, et al. reports three cases of retinal hemorrhages occurring after serious household accidental trauma. In the three patients, aged 13 months, 9 months and 7 months, the retinal hemorrhages were localized to the posterior pole. Betz, et al. examined different groups of traumatic and non-traumatically head injured patients to compare a morphometrical analysis of the eyes. Two adult patients who suffered significant trauma (fall from stairs and a motor vehicle accident) had retinal hemorrhages, and all of the patients who were diagnosed with shaken baby syndrome had retinal hemorrhages. None of the patients with non-traumatic head injury had retinal hemorrhages. Are
Retinal Hemorrhages Caused by Cardiopulmonary Resuscitation? They studied a total of 117 patients. Nine patients had retinal hemorrhages: one patient had a single retinal hemorrhage following 75 minutes of CPR; another patient had multiple small punctate hemorrhages after 60 minutes of CPR. Four patients were determined by the authors to have been abused based on additional findings. Another patient was involved in a motor vehicle accident, and one had significant hypertension. The final patient was a drowning victim; it is notable that no other reports of similar retinal hemorrhages following drowning can be found. Weedn, et al., Kramer, et al., and Bacon, et al. each describe a single case report of an infant or child with retinal hemorrhages following cardiopulmonary resuscitation. The authors felt that these patients did not suffer non-accidental traumatic brain injury. In all three cases, however, the reviewer wonders if non-accidental traumatic brain injury was completely excluded. Gilliland and Lukenbach performed a postmortem study on 169 infants and children to examine if resuscitation is associated with retinal hemorrhages. Seventy patients had retinal hemorrhages after receiving resuscitation attempts, and the majority of these patients had head injuries as the cause of death. Importantly, however, the nature and cause of the head injury was not specified. Fackler et al. used an animal model to determine if CPR causes retinal hemorrhages in piglets. They performed CPR on six piglets for 50 minutes. No retinal hemorrhages were found following the resuscitation of these six piglets even with measurements of right atrial mean pressures of 74 ± 12 mm Hg and mean sagittal sinus pressures of 42 ± 6 mm Hg. Are
Retinal Hemorrhages Caused by Seizures? Do
Retinal Hemorrhages Follow Meningitis? Kennedy describes a 4-month-old with meningococcal meningitis and disseminated intravascular coagulation. The infant had a small number of retinal nerve fiber hemorrhages in the posterior pole of both eyes. The author suggests that the hemorrhages were due to disseminated intravascular coagulation. Are
There Other Causes of Retinal Hemorrhages? Pollack and Tychsen examined a random sample of infants and children after they had received extracorporeal membrane oxygenation. Five patients were found to have retinal hemorrhages; four of the five were neonates. The hemorrhages were all described as single or few dot or flame hemorrhages. Shiono et al. describes two older patients with von Willebrand's syndrome. One patient (19 years old) had vitreous hemorrhages only, but the second patient (13 years old) had retinal, subretinal and vitreous hemorrhages. What
is the Significance of Unilateral Retinal Hemorrhages? All of the children had indirect ophthalmoscopy performed by an ophthalmologist. Tyagi et al. similarly describes three cases of unilateral retinal hemorrhages in children who the authors felt sustained non-accidental head injury. Paviglianti and Donahue describe three infants who were found to have unilateral retinal hemorrhages and ipsilateral cranial hemorrhages. All three cases were "strongly suspicious of nonaccidental trauma". Wilkinson et al. correlated retinal hemorrhages with neurological outcome in shaken baby syndrome. Three of fourteen patients (21%) in their series had unilateral retinal hemorrhages. Kivlin et al. examined the ophthalmologic findings with shaken baby syndrome at one medical center. Of the retinal hemorrhages that were identified by the ophthalmologists, 11/76 (14%) were unilateral. Do
Neonates Have Retinal Hemorrhages? In all of the studies that looked at delivery technique, the highest incidence was seen following delivery with vacuum extraction and the lowest incidence was seen following cesarean section. Sezen et al. and Baum et al. determined the incidence of retinal hemorrhages when neonates were examined within one week of birth. The incidences were 14.3% and 15.5% respectively. Planten et al., Levin et al. and Schenker et al examined neonates within 24 hours of birth. The incidence of retinal hemorrhages in these studies ranged from 19.2% to 37.3%. Sezen et al. additionally looked at the time to resolution of the hemorrhages. Hemorrhages identified as flame shaped resolved within five days. Round, red, deep hemorrhages usually disappeared within 21 days except in one case in which the hemorrhage did not resolve until 6 weeks after birth. Emerson et al. examined neonates within 30 hours of birth and found the incidence of retinal hemorrhages to be 34%. Most of the hemorrhages were gone by 2 weeks of age; one subretinal hemorrhage persisted up to six weeks after birth. Smith et al. randomly selected 46 neonates without perinatal problems for dilated retinal examination. Ten infants were found to have retinal hemorrhages. These ten infants also had a brain MRI looking for evidence of intracranial injury. Only eight of the scans were satisfactory but none of the neonates showed evidence of intracranial injury on MRI. Skalina et al. examined the incidence of retinal hemorrhages in newborn infants with systemic hypertension (defined as mean arterial pressure >70mmHg on at least three separate days). Eight patients had retinal hemorrhages; one infant had splinter hemorrhages which were still visible 10 weeks later. Beratis et al. investigated whether maternal smoking during pregnancy causes retinal abnormalities in the newborn. They used two groups of neonates matched for mode of delivery and gestational size; the neonates were grouped according to whether their mothers smoked during pregnancy or not (self-report). There was an increased frequency of retinal hemorrhages seen in neonates of mothers who smoked during pregnancy when compared to infants of mothers who did not smoke during pregnancy. Does
Purtscher retinopathy occur in children? The authors define Purtscher retinopathy as following a sudden compression of the thoracic cage. The two children in these case reports did not have head imaging, so it is difficult to conclude that thoracic compression is the cause of the hemorrhages. Does
Terson syndrome occur in children? The second study which examined the incidence of intraocular hemorrhages with subarachnoid hemorrhages did not include children. The incidence of Terson syndrome in children, therefore, could not be determined from this study. Interestingly, all of the children in the first study who underwent vitrectomy for vitreous hemorrhages had subdural hemorrhages. What
are the Outcomes of Infants and Children with Retinal Hemorrhages? Kivlin et al. examined clinical and ophthalmological findings in children who were diagnosed with shaken baby syndrome. They found that the presence and bilaterality of retinal hemorrhages indicated a worse prognosis for survival. Han and Wilkinson
examined six children 12 - 55 months following a shaking injury. There
was significant visual morbidity seen in these six cases. In addition,
three of the children had significant neurological disabilities. McCabe
and Donahue performed a retrospective chart review of 30 patients
who were diagnosed with shaken baby syndrome. They found that decreased
vision in these patients was due to retinal scarring, optic atrophy
and cortical visual impairment. Article Summaries Does Accidental Injury Result in Retinal Hemorrhages? Christian CW, Taylor AA, Hertle R, Duhaime AC. Retinal hemorrhages due to accidental household trauma. J Pediatrics 1999;135:125-127. Objectives: Methods: Case 1 * Mechanism:

Results: Conclusion: http://www.sbsdefense.com/Retinal_Hemorrhages.htm Retinal Hemorrhages are small hemorrhages on the back of the eye. Most experts do not agree as to the pattern, number, location or type of retinal hemorrhages that point to a diagnosis of SBS or other nonaccidental trauma. The mechanism(s) behind retinal hemorrhages in infancy in the context of alleged head trauma are unknown. Most research points to a mechanism involving rapid increases in intracranial pressure, cerebral venous spasm or increased venous pressure, and possibly hypoxia. Most studies do not support a mechanical etiology. The presence or absence of retinal hemorrhages and/or its characteristics is often used by prosecution doctors to determine whether or not the case is nonaccidental trauma. This is not a reliable mechanism. Sometimes, the retinal hemorrhages are accompanied by nerve sheath damage or bleeding in the subdural space of the optic nerve. This finding has been considered an indicator of a greater degree of damage. Other times, the hemorrhages are referred to as dot-and-blot hemorrhages or petechiae. These are thought to suggest a lesser degree of force. Retinal hemorrhages in SBS cases are most often bilateral. http://www.bmj.com/cgi/content/full/328/7442/754 A forensic autopsy showed no direct trauma to the orbits or eyes. There were prominent bilateral scalp contusions with soft tissue and intramuscular haemorrhage, symmetrical parietal skull fractures with coronal sutural diastasis, and a lacerated dura mater with extrusion of brain and blood. In addition to bilateral subdural and subarachnoid haemorrhages, a thin epidural haematoma partially covered the frontoparietal, calvarial lamina interna. The brain showed bilateral cortical contusions, severe cerebral oedema, and diffuse anoxic-ischemic injury. Postmortem ocular examination showed haemorrhages of the optic nerve sheaths with subdural haemorrhage greater than subarachnoid haemorrhage. Both eyes had extensive retinal haemorrhages with perimacular retinal folds (fig 2). Retinoschisis and peripapillary intrascleral haemorrhages were evident, and the retinal haemorrhages extended from the posterior pole to the ora serrata affecting the preretinal, intraretinal, and subretinal layers.

Hemorrhages Once again, there is no stated criteria about how "inflicted injury" cases were determined, other than what we know--lack of documented evidence of accidental injury or medical causes. ONE OTHER THING STANDS OUT--the belief that symptoms are different in cases of accidental or inflicted injury. In point...there are no clinical signs which point to the origin of an injury as being accidental or non-accidental. The physiology of the body is constant. The same amount of force whether inflicted or accidental will produce the same result, and that is without even factoring in medical causes.

possible causes for hemorrhages in this age child can be investigated

believed to be diagnostic of SBS are found, other causes are NOT investigated
and eliminated. Thinking "dirty"--If you find retinal hemorrhages, assume Shaken Baby Syndrome. More on retinal hemorrhage: thrombocytopenia, associated with vaccines, drugs, and unknown other causes. Vaccine-induced THROMBOCYTOPENIA journal articles (a small sample from http://scholar.google.com)

METHODS: One hundred and twenty consecutive patients with immune-mediated HIT were recruited over a period of 11 years and studied retrospectively for the occurrence of neurologic complications. Diagnosis of HIT was based on established clinical criteria and confirmed by detection of heparin-induced antibodies using functional and immunologic tests. RESULTS: Eleven of the 120 patients (9.2%) presented with neurologic complications; 7 suffered from ischemic cerebrovascular events, 3 from cerebral venous thrombosis, and 1 had a transient confusional state during high-dose heparin administration. Primary intracerebral hemorrhage was not observed. The relative mortality was much higher (Chi-square test, p < 0.01) in HIT patients with neurologic complications (55%) as compared to patients without neurologic complications (11%). The mean platelet count nadir in neurologic patients was 38 ± 25 x 109/l on average, and was lower in patients with fatal outcome compared to those who survived (21 ± 13 x 109/l versus 58 ± 21 x 109/l; p < 0.05, Wilcoxon test). In three patients neurologic complications preceded thrombocytopenia. There was a high coincidence of HIT-associated neurologic complications with other HIT-associated arterial or venous thrombotic manifestations. CONCLUSION: Neurologic complications in HIT are relatively rare, but associated with a high comorbidity and mortality. HIT-associated neurologic complications include cerebrovascular ischemia and cerebral venous thrombosis. They may occur at a normal platelet count

ABSTRACT ABSTRACT Objective. Child abuse occurs in 1% of children in the United States every year; 10% of the traumatic injuries suffered by children under 5 years old are nonaccidental, and 5% to 20% of these nonaccidental injuries are lethal. Rapid characterization of the injury as nonaccidental is of considerable benefit to child protection workers and police investigators seeking to safeguard the child care environment and apprehend and prosecute those who have committed the crime of child abuse. Physically abused children present with a variety of well-described injuries that are usually easily identifiable. In some cases, however, particularly those involving children with the shaken baby syndrome, obvious signs of physical injury may not exist. Although external signs of such an injury are infrequent, the rapid acceleration-deceleration forces involved often cause subdural hematomas and retinal hemorrhages, hallmarks of the syndrome. Frequently, retinal hemorrhages may be the only presenting sign that child abuse has occurred. Complicating the interpretation of the finding of retinal hemorrhages is the belief by some physicians that retinal hemorrhages may be the result of chest compressions given during resuscitative efforts. The objective of this study is to determine the prevalence of retinal hemorrhages after inpatient cardiopulmonary resuscitation (CPR) in pediatric patients hospitalized for nontraumatic illnesses in an intensive care unit. Design. Prospective clinical study. Setting. Pediatric intensive care unit. Patients. Forty-three pediatric patients receiving at least 1 minute of chest compressions as inpatients and surviving long enough for a retinal examination. Patients were excluded if they were admitted with evidence of trauma, documented retinal hemorrhages before the arrest, suspicion of child abuse, or diagnosis of near-drowning or seizures. All of the precipitating events leading to cardiopulmonary arrest occurred in our intensive care unit, eliminating the possibility of physical abuse as an etiology. Interventions. None. Measurements. Examination of the retina was performed by one of two pediatric ophthalmologists within 96 hours of CPR. The chart was reviewed for pertinent demographic information; the platelet count, prothrombin time, and partial thromboplastin time proximate to the CPR were recorded if they had been determined. Results. A total of 43 pediatric patients hospitalized with nontraumatic illnesses survived 45 episodes of inpatient CPR. The mean age was 23 months (range, 1 month to 15.8 years), and 84% of the patients were under 2 years old. The majority of the patients (44%) were admitted to the intensive care unit after surgery for congenital heart disease, and another 21% were admitted for respiratory failure. The mean duration of chest compressions was 16.4 minutes ± 17 minutes with 58% lasting between 1 and 10 minutes. Five patients had chest compressions lasting >40 minutes, and two patients had open chest cardiac massage. All patients survived their resuscitative efforts. Ninety-three percent of patients had an elevated prothrombin time and/or partial thromboplastin time while 49% were thrombocytopenic. Sixty-two percent of the patients had low platelet counts and an elevated prothrombin time and/or partial thromboplastin time. Small punctate retinal hemorrhages were found in only one patient. Conclusions. Retinal hemorrhages are rarely found after chest compressions in pediatric patients with nontraumatic illnesses, and those retinal hemorrhages that are found appear to be different from the hemorrhages found in the shaken baby syndrome. Despite the small number of patients in this prospective study, we believe that these data support the idea that chest compressions do not result in retinal hemorrhages in children with a normal coagulation profile and platelet count. A larger number of patients should be evaluated in a prospective multi-institutional study to achieve statistical significance in a nondescriptive study. retinal hemorrhages, CPR, shaken baby syndrome, child abuse, coagulopathy. INTRODUCTION Child abuse occurs in 1% of children in the United States every year; 10% of the traumatic injuries suffered by children younger than 5 years are nonaccidental, and 5% to 20% of these nonaccidental injuries are lethal.1,2 Rapid characterization of the injury as nonaccidental is of considerable benefit to child protection workers and police investigators seeking to safeguard the child care environment and apprehend and prosecute those who have committed the crime of child abuse. Physically abused children present with a variety of well-described injuries that are usually easily identifiable.2 However, in some cases, particularly those involving children with the shaken baby syndrome, obvious signs of physical injury may not exist.3 Although external signs of such an injury are infrequent, the rapid acceleration-deceleration forces involved often cause subdural hematomas and retinal hemorrhages, hallmarks of the syndrome. Frequently, retinal hemorrhages may be the only presenting sign that child abuse has occurred. Several studies have documented that retinal hemorrhages occur in a large percentage of child abuse cases, especially those resulting from shaken baby syndrome.5 Some physicians believe these lesions are pathognomonic for nonaccidental injury.5,11,12 Other physicians, however, have suggested that chest compressions performed during cardiopulmonary resuscitation (CPR) may cause retinal hemorrhages.13,14 This is supported by one prospective study14 and several anecdotal case reports. However, in nearly all cases the cardiopulmonary arrest was unwitnessed, and therefore, the etiology of the arrest is not accurately known. Furthermore, coagulation studies and platelet counts have not always been documented in these reports, and thus, the possible propensity for bleeding in these patients was not completely evaluated. The still unanswered questions about the relationship between retinal hemorrhages and CPR have obvious medical, legal, and social implications. The physician caring for the child presenting with retinal hemorrhages must decide whether these lesions were caused by physical abuse or resulted from chest compressions given by care givers or emergency personnel. This study was undertaken to help elucidate a possible association between chest compressions performed during in-hospital CPR and retinal hemorrhages in pediatric patients admitted to the hospital for nontraumatic illnesses. METHODS AND MATERIALS Dilated fundus examinations were performed at the bedside by one of two pediatric ophthalmologists within 96 hours of the arrest and chest compressions. The posterior pole and midperipheral retina to the equator were visualized. The number, size, and type of retinal hemorrhages were recorded. Coagulation studies, including a prothrombin time (PT) and partial thromboplastin time (PTT), and platelet counts were performed near the time of the CPR for many patients at the discretion of the attending physician. The patient's age, admission diagnosis, history of retinopathy of prematurity, etiology of arrest, length of chest compressions, coagulation studies results, platelet counts, and ophthalmological examination findings were recorded. A descriptive analysis was performed on the data. RESULTS Table 1. Characteristics
of Patients Evaluated for Retinal Hemorrhages After Chest Compressions The precipitating events for each of the 45 cardiopulmonary arrests are shown in Table 2. A plugged or dislodged endotracheal or tracheostomy tube was determined to be the cause in 11 of 45 arrests requiring chest compressions. Other precipitating events included respiratory failure secondary to apnea, bronchspasm, or aspiration (8/45), arrythmias (5/45), hyperkalemia (5/45), tension pneumothorax or hydrothorax (3/45), cardiac tamponade (2/45), sepsis (2/45), and primary myocardial ischemia (1/45). In 7 of 45 episodes of cardiopulmonary arrest, the precipitating event was indeterminate. Table 2. Precipitating
Events for 45 Cardiopulmonary Arrests Requiring Chest Compressions
of Patients Evaluated for Retinal Hemorrhages Mean CPR interval was 16.4 ± 17 minutes and ranged from 1 minute to 60 minutes (Table 3). The majority of the episodes of chest compressions lasted for 1 to 10 minutes (26/45), although 6 of 45 lasted 11 to 20 minutes, 8 lasted 21 to 40 minutes, and 5 lasted for >40 minutes (Table 3). Two patients in our study had open chest cardiac massage during their resuscitation. Ophthalmologic examinations performed by pediatric ophthalmologists within 96 hours of the chest compressions revealed multiple small punctate retinal hemorrhages bilaterally after 1 of the 45 episodes of chest compressions (Table 3). These hemorrhages were different than those observed in the shaken baby syndrome. Table 3. Chest
Compressions in Pediatric Intensive Care Unit Patients and the Prevalence
of Retinal Hemorrhages Coagulation studies were performed near the time of the arrest in 29 of the 45 episodes of chest compressions (Table 4). Either the PT or PTT was elevated in 27 of these 29 episodes (93%). Platelet counts were evaluated in 41 of the 45 episodes. Fewer than 2 × 105 platelets/µL were found in 20 of these 41 episodes (49%). Both platelet count and PT or PTT were abnormal in 29 episodes of chest compressions with 18 (62%) of these patients having abnormal values for both measurements. Table 4. Coagulation
Profiles and Platelet Counts Near the Time of Chest Compressions of
Patients Evaluated for Retinal Hemorrhages DISCUSSION Whether or not retinal hemorrhages can be caused by chest compressions obviously has important medical, legal, and social implications. The consequences of misdiagnosing child abuse and attributing retinal hemorrhages to CPR can have devastating consequences for the child and other children in the care of the abuser. However, wrongly accusing a care giver of child abuse can be equally disastrous. The physician caring for the child presenting with retinal hemorrhages must decide if these ocular lesions were caused by physical abuse or the result of chest compressions that care givers or emergency personnel may have given the child. Thus, it is important to determine if retinal hemorrhages are found after chest compressions given during resuscitative efforts. In our study, one 1-month-old patient was found to have retinal hemorrhages after chest compressions. This patient had 60 minutes of chest compressions that were done via open chest cardiac massage. Her PT was 22.9 seconds, PTT was 78 seconds, and her platelet count was 91 000 platelets/µL. These retinal hemorrhages were also morphologically different from the retinal hemorrhages observed in the shaken baby syndrome in that they were numerous, small punctate hemorrhages. Retinal hemorrhages were not found after any other of the 44 episodes of chest compressions, despite a majority of these patients also having a coagulopathy and/or thrombocytopenia. A second patient of the same age also had prolonged open chest cardiac massage, elevated PT and PTT and decreased platelets. This patient had no retinal hemorrhages on examination by the pediatric ophthalmologists. Thus, we find no patients with normal coagulation studies and platelet counts who have retinal hemorrhages after chest compressions. Furthermore, retinal hemorrhages are a rare finding after chest compressions in patients with a coagulopathy or a low platelet count and are atypical of retinal hemorrhages seen in shaken baby syndrome. Although the numbers are limited, other studies also support this conclusion. Kanter18 performed a prospective study on 54 children who underwent chest compressions. Six of the 54 children had retinal hemorrhages. In five of these patients, trauma or child abuse was the precipitating event of the cardiac arrest, although the sixth patient had seizures and severe arterial hypertension. Both of these conditions are known risk factors for the development of retinal hemorrhages.19,20 Kanter18 concluded that trauma should be assumed when retinal hemorrhages are found and that retinal hemorrhages should not be attributed to CPR alone. Our study differs in that all arrests occurred in the intensive care unit whereas the patients in Kanter's study occurred outside of the hospital. In addition, the events leading up to the arrest were witnessed, and all patients survived their resuscitations. Gilliland and Luckenbach21 microscopically examined at autopsy the retina of 169 children who underwent prolonged resuscitative efforts. Seventy children had retinal hemorrhages, and the etiology of all but one were attributed to illnesses with which retinal hemorrhages have been associated. The cause of the cardiac arrest for the one patient with retinal hemorrhages who died despite chest compressions was listed officially as undetermined. This child came from a home in which two other pediatric deaths had occurred and episodes of abuse had been documented. Thus, these authors concluded that their data did not support the idea that retinal hemorrhages are caused by CPR. However, some reports have suggested that chest compressions given during resuscitative attempts can result in retinal hemorrhages.13,14, 22 Although one of these reports is a prospective evaluation of children who received CPR, most reports are anecdotes in which the arrests were not witnessed by anyone but the care giver. In fact, in the prospective study, one of the two arrests occurred out-of-hospital although the cause of the in-hospital arrest was unwitnessed and the diagnosis of sudden infant death was made.14 In most of these cases, intentional injury cannot be entirely ruled out. In most cases coagulation studies were not done. One case report describes an 17-month-old female infant who was evaluated for probable adenoviral gastroenteritis who had no retinal hemorrhages on her initial examination by an attending pediatrician.13 This patient experienced a respiratory arrest and required approximately 60 minutes of chest compressions. She was transported to another hospital and on evaluation had multiple scattered intraretinal and subhyloid hemorrhages. Her PT and PTT were normal, but her platelet count was low at 167 000/µL. This patient is similar to our one patient who had retinal hemorrhages in that both received chest compressions for about 60 minutes and both were thrombocytopenic. Of the other four patients in our study who had chest compressions for >40 minutes, two were thrombocytopenic, and all had elevated coagulation studies, but none of them had retinal hemorrhages. Thus, in cases with prolonged chest compressions, thrombocytopenia may be a risk factor for the development of retinal hemorrhages. This study has the following limitations. First, the number of patients reported in this study is small. An adequate number of patients would require a multiinstitutional study. Second, a direct causal effect of chest compressions on retinal hemorrhages cannot be practically assessed using this approach. Pre-arrest fundoscopic examinations would need to be performed on every patient admitted to our unit, but this would be impractical because of the large volume of patients admitted to our unit. However, we believe that the approach used in this study will determine if there is an association of retinal hemorrhages with chest compressions and perhaps identify risk factors for developing retinal hemorrhages after chest compressions. Third, we did not examine the retina of children who did not survive their CPR. The frequency of retinal hemorrhages in this population of children may differ from the frequency seen in children who survive their resuscitation and may warrant further study. In summary, we evaluated the fundi of 43 children after 45 episodes of chest compressions. All of the precipitating events leading to cardiopulmonary arrest occurred in our intensive care unit, eliminating the possibility of physical abuse as an etiology. Despite coagulopathies in the majority of the cases, retinal hemorrhages were found in only one patient who underwent an open chest cardiac massage and had an extensive coagulopathy. No retinal hemorrhages were found in the patients who had normal coagulation studies or only abnormal PT/PTT or an abnormal platelet count. Despite the small numbers of patients in this prospective study, we believe that these data support the idea that chest compressions do not result in retinal hemorrhages in children with a normal coagulation profile and platelet count. Furthermore, retinal hemorrhages are an infrequent finding in children with abnormal coagulation studies and low platelet counts. A larger number of patients should be evaluated in a prospective multiinstitutional study to achieve statistical significance in a nondescriptive study.
