ABSTRACT
Objective:To explore the chest drainage effect of use different diameter thoracic drainage tube after biportal thoracoscopic radical resection for lung cancer.Methods:300 patients with lung cancer who received biportal thoracoscopic radical resection were divided into group A and group B from January 2018 to September 2020. Group A: 150 patients with single 28# thoracic drainage tube after surgery. Group B: 150 patients with single 20# thoracic drainage tube and a negative pressure drainage ball after surgery. The postoperative drainage volume, drainage time, postoperative pain, postoperative thoracic puncture, hospital stay and total hospital expenses were compared.Results:No significant difference between the two groups in terms of sex, age, postoperative pathological type and resection range. There no significant difference between the two groups in total drainage volume [(1 010.31±525.29)ml vs.(985.35±403.93)ml] and total drainage time [(5.69±2.55)days vs.(5.42±1.94)days]. The difference of different diameter thoracic drainage tube used [(5.69±2.55)days vs.(2.88±0.64)days] was statistically significant. There were significant differences between two groups in terms of hospital stay[(12.64±2.89)days vs.(11.25±1.62)days] and total hospital expenses[(62 899.00±1 588.82) yuan vs.(64 327.00±3 587.04)yuan]. No significant differences on the postoperative first day, second day and third day in VAS pain scores. However, on the postoperative fifth day, the difference was statistically significant. In addition, the rate of group A postoperative thoracic puncture was 10%, group B was 0, the comparison was statistically significant.Conclusion:Using a single thin thoracic drainage tube and plus a negative pressure drainage ball after biportal thoracoscopic radical resection for lung cancer will not cause pain increase, shorten hospital stay days, control the rate of postoperative thoracic puncture and then reduce patients total hospital expenses.
