自发性气胸单孔胸腔镜手术后肺部并发症预测模型的构建OACSTPCD

Objective:To investigate the construction of prediction model of pulmonary complications in patients with spontane-ous pneumothorax after single port thoracoscopic surgery.Methods:From May 2021 to May 2022,106 patients with spontaneous pneu-mothorax who had undergone single port thoracoscopic surgery were selected and divided into complication group(n=22)and non-complication group(n=84)according to the occurrence of postoperative lung complications.The clinical data of the patients in two groups were analyzed by univariate and multivariate analysis,and the risk factors affecting postoperative pulmonary complications were screened out,and the prediction model was constructed by nomogram.Results:Age,smoking history,pulmonary disease,severe pleural adhesion,number of pulmonary bullae,pain grade 24 h after surgery,and intraoperative blood loss in the complication group were higher than those in the non-complication group,preoperative albumin level was lower.Multivariate logistic regression analysis showed that age≥50 years old(OR=1.240,95%CI=1.064～1.445),pulmonary disease(OR=26.154,95%CI=1.224～558.648),severe pleural adhesion(OR=23.289,95%CI=2.940～184.520)and the number of pulmonary bullae＞2(OR=2.878,95%CI=1.787～4.633)were independent risk factors for postoperative pulmonary complications(P＜0.05).The area under receiver operating charac-teristic curve of the predictive model established based on the above risk factors for predicting postoperative pulmonary complications was 0.82(95%CI=0.756～0.874),the sensitivity and specificity was 82.33%and 65.47%,respectively.Conclusions:Age,pul-monary disease,severe pleural adhesion,and the number of pulmonary bullae are independent risk factors for pulmonary complications after single port thoracoscopic spontaneous pneumothorax operation.The prediction model based on these factors has good predictive val-ue for predicting the risk of postoperative pulmonary complications.
