손상정도계수(ISS)를 이용한 보행자 외상 환자의 중증도 분석

Abstract

Background : This study shows analysis of the factors influencing the severity of pedestrian trauma patients by Injury Severity Score(ISS) and find ways for improvement. Motor vehicles make people's life easy and comfortable, but at the same time they are dangerous enough to be injured or die. Especially for the case of pedestrian accidents, people are directly exposed to great danger without any security equipment, which causes higher mortality than car to car accidents.

Method : The patients were pedestrian trauma and the mumber of patients was 126 who visited one of emergency medical center in Chosun university hospital from January 1, 2007 to December 31, 2007. Patients were grouped based personal characteristics, situation of accident, car occupants, hospital transfer, days of hospital treatment, injured part of body, amount of transfusion and so on. We analyzed the medical data by using SPSS 16.0 for window.

Result : Of 126 patients, 76 were men(61.9%), 48 were women(38.1%) and

20 died. Those who died in a couple of days from the date of accident

recorded higher ISS. The average age of all patients was 43.1. The severity of patients over 40 is higher than that of those less than 40. Cloudy days had more accidents in city streets. The most frequently injured part of body was extermities (38.9%), and ISS reached the highest when working in agriculture, transferred from other medical centers, and injured abdomen. Below 8 points of ISS were 45, and 9-15 points were 36, above 16 points were 45 patients. Hospital stay averaged 16 days, and intensive care unit 2 days.

Conclusion : The results reveal that it is not unusual that pedestrians are injured by automobiles in daily life. Awareness of risk factors would be useful in designing effective prevention strategies and in comprehensive prehospital and inhospital treatment of motor vehicle trauma patients. To decrease？ sevirity, we should be？cautious？about the patients over 40, doing agriculture, and transferred from other medical centers. Also those of injured abdomen should be treated carefully.
