摘要
目的 :分析影响普胸外科术后呼吸衰竭可控因素 ,加以初步量化并建立评判方程。方法 :选取 1981年7月～ 1998年 12月术后急性呼吸衰竭患者 85例及随机选取肺癌、肺结核、纵隔肿瘤及食管手术等常见疾病患者 30 0例为对照组 ,数值化相关的可控因素。经 L ogistic回归得到最主要的可控因素及相应系数 B值建立 L o-gistic回归方程。结果 :主要的可控因素为肺功能、营养状况、吸烟指数和手术操作 4类 10项因素。应用 L ogistic回归方程计算所得与实际发生术后呼吸衰竭人数的比较 ,两者的相关系数为 0 .886 (P=0 .0 0 1)。该方程的判定灵敏度与特异度分别为 5 8.82 %和 94.0 0 %。结论 :本研究经 L ogistic回归 ,指出了影响术后呼吸衰竭发生的最主要可控因素及初步量化结果 。
Objective:To establish quantification system based on the manageable risk factors associated with the development of postthoracic surgery acute respiratory failure (ARF).Methods:Eightyfive cases of postoperative ARF and 300 cases without ARF served as controls were included.Logistic regression was processed for analysing the manageable risk factors and establishing logistic equation.Results:Variables selected to be important included nutritional condition,cigarets index,lung function and surgical procedures.Logistic equation was then established.Correlation coefficient between predicted and actual ARF numbers due to different risk scales was 0 886( P =0 001).Conclusions:With logistic regression,the manageable risk factors associated with postthoracic surgery ARF are tentatively quantified.It is of clinical significance to use the established quantification system based on these factors,in evaluating the therapeutic outcome of a highrisk patient.
