ABSTRACT
@#Objective 聽 聽To investigate the correlation between the postoperative day 1 (POD1) drainage volume and postoperative pulmonary complications (PPCs). Methods 聽 聽The clinical data of 254 non-small cell lung cancer (NSCLC) patients undergoing thoracoscopic lobectomy at our department from January 2014 to June 2018 were retrospectively reviewed. According to whether there were PPCs after operation, patients were divided into a PPCs group (51 patients, 33 males and 18 females, aged 65.2卤7.3 years) and a non-PPCs group (203 patients, 110 males and 93 females, aged 62.4卤8.2 years). The correlation between POD1 drainage volume and PPCs was analyzed. Results 聽 聽The POD1 drainage volume in the PPCs group was significantly more than that in the non-PPCs group (337.5卤127.4 ml vs. 208.7卤122.9 ml, P=0.000). The result of regression analysis showed that POD1 drainage volume was an independent risk factor for the occurrence of PPCs. Receiver operating characteristic curve (ROC curve) analysis showed that POD1 drainage volume of 265 ml was the cut-off point to predict PPCs. The rate of PPCs in the group of POD1 drainage volume less than 265 ml was significantly lower than that in the group of drainage volume more than 265 ml (8.3% vs. 43.0%, P=0.000). Conclusion 聽 聽The POD1 drainage volume is closely related to the occurrence of PPCs, which can be used to predict the occurrence of PPCs.
