Presence of periorbital and conjunctival petechial hemorrhages in accidental pediatric drowning.
The pathological findings of drowning are variable and non-specific. Petechial hemorrhages involving the periorbital region and the conjunctiva have been described in many causes of death, but are thought to be exceedingly uncommon in cases of drowning. However, such studies have not specifically addressed the pediatric population. The current study retrospectively examined 79 cases of accidental pediatric drowning for the presence of periorbital/conjunctival hemorrhages and analyzed factors that may have affected their presence. Ten victims had periorbital/conjunctival petechial hemorrhages (13%), with five having periorbital petechiae, three having conjunctival petechiae, and two having both periorbital and conjunctival petechiae. The age and gender of the victim, site of drowning, resuscitation history and the presence of other pathological findings were not significantly associated with the presence of periorbital/conjunctival petechiae. However, as the interval between the drowning episode and autopsy increased, the incidence of periorbital/conjunctival petechiae decreased (28% for <24h; 7% for >24h). The presence of periorbital/conjunctival hemorrhages in a significant proportion of pediatric drowning victims confirms that the pathologist must add this finding to the spectrum of changes seen in pediatric drowning.
