Abstract

The proportion of emergency operation is increasing gradually and the state of emergency patients is more critical than elective patients because of poor physical and laboratory examinations. The evaluation of perioperative data will improve the outcome of emergency operation. We analyzed l654 cases of emergency anesthesia performed at Presbyterian Medical Center from January to December 1994. The patients were evaluated clinically and/or statistically according to age and sex, ASA clssification of physical status, preoperative NPO time, day and month of operation, premedicants, department and diseases, concurrent diseases, place of preoperative patient care, time from administration of emergency room to operation room, trauma, anesthesia duration and methods, beginning time of operation, frequency of transfusion, and postoperative mortality rate. The results were as follows; 1) The percent of emergency surgery was 29.2% of total surgical patients. 2) There were 22.5% of cases whose NPO time was less than 8 hours. 3) The most common premedicant was glycopyrrolate only(32.4%). 4) 50.5% of emergency operation was performed by obstetrics and gynecology department and most common operation was Cesarean section(43.6%). 5) The most common concurrent disease was viral B hepatitis(23.3%). 6) The percent of injury was 13.5% of total emergency operation. Blunt trauma was 71.0% and penetrating trauma was 29.0%. 7) The most common anesthesia method was inhalation anesthesia with enflurane(55.4%) and followed by intravenous anesthesia with propofol(31.8%). In conclusion, anesthesiologists should attention to perioperative management to decrease the incidence of morbidity and mortality of emergency operation.
