Application of Abbreviated Injury Scale and Injury Severity Score to 115 Thoracic Trauma Cases-A Retrospective Study

Injury and poisoning were leading causes among the ten most commonly reported illnesses in Far Eastern Memorial Hospital since 1985. Herein we apply the Abbreviated Injury Scale (AIS) and Injury Severity Score (ISS) to 115 thoracic trauma victims retrospectively. For assessment of the results for both blunt thoracic trauma patient (Grop I) and penetrating throacic injury patients (Group II) in terms of hospital days, usage of ventilator, and mortality. Group I, 83 cases, 29% (24/83) of those (ISS≧16) have an average 22.3 hospitalization day, 71% (59/83) (lSS ＜ 16) 8.7 days, one (lSS =34) mortality on the eleventh day. Group II, 32 cases, 12% (4/32) (ISS≧16) 20.5 days, 87.5% (28/32) (ISS ＜ 16) 7.5 days, no mortality in Group II. The occurrence of ventilator usage was as follows: ISS=17.20%; ISS=18. 60%: ISS=29.66%; and ISS= 34, 100%. It indicates that the higher ISS score the more they take the advantage of ventilator.
