Predicting discharge in uncomplicated near-drowning

To determine if routine, noninvasive parameters could be measured which predict early (4–6 hour) discharge from the emergency department (ED) in mildly symptomatic and asymptomatic victims of childhood near-drowning, a retrospective cohort study was undertaken. Patients with fresh water near-drowning were studied over a 3-year period who presented with Glascow Come Scale (GCS) ≥13 and required no advanced life support prior to or ≤4 hours after ED presentation. Three groups of patients were found: 39 patients (81%) had normal pulmonary examination (PEx) and normal room air oxygen saturation (RASaO2) by 4 to 6 hours and did not deteriorate during the hospital admission (<24 hours); 5 patients (10%) had normal PEx by 4 to 6 hours and RASaO2 by 8 to 12 hours and did not deteriorate during hospitalization (<24 hours). Four patients (8%) were hospitalized for more than 24 hours. No patient with normal RASaO2 at 6 hours deteriorated while in the hospital (Cl 92.3–100%). Children who present to the ED with GCS ≥13 and have normal PEx/respiratory effort and RA-SaO2 more than 95% at 4 to 6 hours after ED presentation can be safely discharged home.
