폐손상 점수(Lung Injury Score)와 중환자 사망률 예측도

Abstract

Introduction : Lung Injury Score(LIS) provides a quantitative method for scoring acute lung injury that usually occurs after sepsis. The aim of this study is to evaluate the LIS in prediction the patients outcome and determine the relationship between the LIS and mortality rate, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score and multiple organ failure(MOF) score. Methods : Patients admitted to Intensive Care Unit(ICU), Severance Hospital Yonsei University College of Medicine from November 1995 to March 1996 were included. LIS at admission and discharge, APACHE Ⅱ score with MOF score and duration of ICU stay between survivors and nonsurvivors were compared. Relationship of LIS between mortality rate and APACHE Ⅱ score and MOF score were evaluated. Results : LIS is higher in nonsurvivors than survivors at admission and discharge with statistical significance. LIS of survivors and nonsurvivors at discharge was lower and higher than those at admission(p<0.05) respectively Correlation coefficient of LIS with mortality rate, MOF score and APACHE Ⅱ score were 0.60(p<0.05), 0.23 and 0.17. Conclusions : LIS score was highly correlated with mortality rate. Therefore LIS is a good predictor of outcome in the intensive care unit.
