What is the minimum length of time all near-drowning victims should be kept under observation in the hospital?

For near-drowning victims, the minimum length of time for hospital observation is typically recommended to be 23 hours. This observation period is crucial to monitor any potential complications that may arise, such as respiratory distress, pulmonary edema, or other delayed effects of immersion in water.

During this time, medical professionals can conduct a thorough evaluation, which includes continuous monitoring of vital signs, assessing lung function, and determining the need for interventions such as supplemental oxygen or advanced respiratory support. The decision to keep a patient for this duration is based on the understanding that some complications may not present immediately after the incident but could develop within the first day following the near-drowning event.

In contrast, the other time frames suggested—12 hours, 24 hours, and 48 hours—either fall short of adequately ensuring patient safety or exceed the general guideline for straightforward near-drowning cases without significant complications. Thus, 23 hours strikes a balance that allows for necessary medical observation while also being sufficient for most typical cases.
