摘要
目的研究肺气肿指数(EI)对高原地区老年患者肺叶切除术后呼吸并发症的预测价值。方法收集我院2016年5月至2017年12月期间收治的行肺叶切除术的老年患者68例,年龄60-79岁。均于术前检测肺气肿指数(EI)及肺功能(PFT)指标,观察术后呼吸并发症并进行统计学分析。结果经多因素Lo-gistic回归分析,EI和DLCO的OR值分别是19. 51和19. 18(P <0. 01),提示EI和DLCO是术后呼吸并发症的独立预测因素。应用ROC曲线,并经MedCalc软件比较二者ROC曲线下面积(AUCs),EI大于DLCO(P=0. 0305 <0. 05),提示EI对术后呼吸并发症的预测更敏感。结论肺气肿指数(EI)是一项预测肺叶切除术后发生呼吸并发症的更加敏感的指标。
Objective To study the predictive value of EI for elderly patients underwent lobectomy at high altitude. Methods From May,2016 to November,2017,68 elderly patients were underwent lobectomy and observed postoperative pulmonary complications. They all were examined EI and PFT before operation. Results Through logistic multivariate analysis,EI and DLCO were independent risk predictive factors. Comparing the area under curve of ROC,EI was greater than DLCO. EI had more stronger association with postoperative complications. Conclusion EI can be regard as a more sensitive predictive factor for postoperative pulmonary complications.
