Diagnosis of sudden death in infants due to acute dehydration.
When infants die suddenly of acute dehydration, clinical signs and autopsy findings may be equivocal or absent, and microbiologic cultures often are not helpful. Vitreous humor electrolyte and urea nitrogen concentrations were measured in 53 infants dying of gastrointestinal infections, sudden infant death syndrome (SIDS), other infectious diseases, and miscellaneous causes to determine whether these parameters would assist in the recognition and confirmation of deaths resulting from dehydration. Significant differences were found when comparing the mean sodium and urea nitrogen levels of infants dying of gastrointestinal infections with those succumbing to SIDS or other causes. We recommend that these determinations be routinely performed whenever the gross autopsy findings are insufficient to explain the death.
