What is the prudent observation window recommended for a child after a nonfatal submersion event where they seem completely well?
Answer
at least 8 to 24 hours
Due to the potential for delayed onset of complications, specifically worsening pulmonary edema or subtle symptoms related to hypoxia that might not be immediately apparent, it is prudent to maintain close caregiver supervision for a minimum observation period of 8 to 24 hours following any nonfatal submersion involving a child, even if the child appears completely recovered and is talking normally upon leaving the water. This extended precautionary window ensures that subtle signs of distress, which can arise hours later due to the physiological instability caused by water aspiration, are recognized and addressed by medical professionals promptly.
