(Redirected from Submersion Injuries (Drowning))
- Definition: "The process of experiencing respiratory impairment from submersion/immersion in liquid"
- Term "near-drowning" no longer used
- Three possible outcomes = death, survival with morbidity, survival without morbidity
- Consider secondary causes such as intoxication, syncope, cardiac arrhythmia, ACS, non-accidental trauma, etc.
- Submersion → voluntary breath holding → aspiration → coughing/laryngospasm → aspiration continues → hypoxia → death
- Aspiration destroys surfactant which → alveolar collapse, atelectasis, non-cardiogenic pulmonary edema, and V-Q mismatch.
- Immersion pulmonary edema
- Submersion injury (drowning and near-drowning)
- Scuba diving emergencies
- Lightning injuries
- Marine toxins and envenomations
- Spinal cord trauma
- CXR (on arrival and after 4 hours)
- Other work-up generally not needed unless specifically indicated by history or exam, but may consider:
- Labs, EKG
- CT head/C-spine (if history of trauma) - C-spine injury extremely unlikely without evidence or history of trauma (<0.5% in large cohort study)
- Supportive care based on presentation is cornerstone of management.
- Discharge after 4-6 hours of observation if:
- Normal mental status, SpO2 >95% on room air, normal CXR and respiratory exam
- Admit all others
