Clinical effects of two different drainage patterns after thoracoscopic lobectomy / 中国基层医药

ABSTRACT

Objective To analyze the clinical effect of two different drainage methods after video-assisted thoracoscopic(VATS) lobectomy,and to explore the safety,reliability and practicability of clinical application of thoracic drainage tube in Department of Thoracic Surgery.Methods 1 120 cases who underwent VATS lobectomy were selected.According to different drainage methods,they were divided into two groups.560 cases in the observation group received 16-18 silicone elastic drainage,560 patients in the control group received 28-30 traditional silicone chest tube drainage.After drainage,drainage time,residual pleural fluid volume,pain score,catheter site infection rate,the incidence of pneumothorax after extubation,postoperative incidence rate of pulmonary atelectasis were compared between the two groups.Results The postoperative pleural flow of the observation group was (816 ±176) mL,which was less than (1 580 ± 204) mL of the control group,the difference was statistically significant (P =0.006).The drainage days [(5.01 ± 0.57) d],the pleural fluid volume [(2.1 ± 0.6) cm],the catheter site infection rate (0.017％),extubation pneumothorax rate (0.017％),incidence rate of postoperative atelectasis (0.16％) in the observation group were lower than those in the control group [(8.45 ± 1.24) d,(4.3 ± 0.9) cm,0.031％,0.053 ％,0.031％],the differences were statistically significant (all P ＜ 0.05).The NRS pain score between the two groups had statistically significant difference (x2 =16.24,P ＜ 0.001).Conclusion Curative effect of thin tubedrainage after VATS lung resection is safe and reliable,and can reduce the patients' postoperative pain discomfort caused by drainage tube and related complications,it is worthy of clinical popularization and application.
