Abstract
Purpose : Drowning is a process resulting in primary respiratory impairment from submersion in a liquid medium and one of leading cause of accidental death. The purpose of this study was to investigate the clinieal characterisitcs of submersion injury in Jeju and to find the prognostic factors in the treatment of submersion injury.Methods : A total 46 patients who were treated for submersion injury in Cheju National University Hospital from May 2003 to February 2006 were reviewed retrospectively. DOA(death on arrival) group and the other group wecompared according to the outcome in ED(emergency department) and ED discharge group and admission group were compared according to the disposition in ED. Also, death group and survival group were compared according to the final outcome in admission group.Results : Among 46 submerged patients, there were 30 males and 16 females, and their mean age was 29.7±21.1 years. The most common age group, season, and type of water were childhood, summer, salt water respectively and the mean duration of submersion was 7.0±8.4 minutes. DOA group showed significantly longer duration of submersion, higher K and PCO2. and lower pH. PO2. SaO2 compared to the other group. Admission group showed significantly higher Na and PCO2 and lower PO2, SaO2 compared to ED discharge group. Death group showed significantly longer duration of submersion and higher Cr compared to survival group in final outcome.Conclusion : Prognosis of submerged patients could be predicted by some factors such as K. PCO2. pH. PO2.SaO2, and Cr.
