摘要
为了对我院烧伤治疗效果作出评价,我们查阅了近八年(1979～1986)和既往十八年(1961～1978)的全部病历,获得完整资料共1002例(其中近八年为570例),分以上两个年代组进行对照分析。分析方法及结果一、生存率概率单位分析: 将两个年代组患者分别以烧伤总面积(TBS)和Ⅲ°面积(Ⅲ°A)分组,组距10。以TBS和Ⅲ°A各组的均数作自变量x,相应的生存率概率单位作应变量y,求出各自的回归方程、生存率为50％的预计面积(LA50)及其95％的可信限(表1)。根据回归方程作回归直线图1、2;
The Patient Population for this study consists of 655 burn patients abmitted to our hospital between years 1979～1986. Patients who had no complete hospital records are exeluded, leaving 570 to be studied. To assess their curative effect, data from these 570 treated cases were analyzed using statistical techniques such as probit analysis of survival rate. Comparing with the prior 18 yearperioad (1961～1978, 432 cases), the survival rate has shown a marked rise in recent eight years(1979~1986). It can also also be seen that the LA_(50) for tota larea burned(TBS) has in- creased to 85.98 per centr, and the LA_(50) for area of third degree burn (Ⅲ·A) has increased to 54.24 per cent; the standardized fatality rate has dropped to 5.74 per cent during the 1979～1986 period as compared with the former 15.03 per cent, difference between them being statistically markedly significant. The therapeutic duration of 516 cases with burn severity indices(BI) of less than 40 per cent(comparing with 364 prior cases) has been markedly shortened as well. The above obviously better curative effect during the recent 1979～1986 interval ought to be attributed to the marked drop of septicemic/septicopyemic complications, as well as the improvement in preventive and control measures for burn shoeck.
