A patient who survives near-drowning develops hypoxia-induced cerebral edema.

Hypoxia-induced cerebral edema after a near-drowning incident can be managed by administering osmotic diuretics like mannitol. These medications help reduce intracranial pressure by drawing fluid out of the brain tissue and into the bloodstream, thereby alleviating cerebral edema. Maintaining a MAP of 60-70 mm Hg may not be sufficient to address the elevated intracranial pressure, keeping the patient flat could worsen cerebral edema, and hyperventilation with a PaCO2 of 40-45 mm Hg is not typically recommended for managing increased intracranial pressure as it can lead to vasoconstriction and decreased cerebral perfusion.
