Effect of perioperative aspirin administration on bleeding in patients undergoing video-assisted thoracoscopic pulmonary wedge resection / 中华全科医师杂志

ABSTRACT

Objective:To explore the effect of perioperative aspirin administration on intraoperative and postoperative bleeding in patients undergoing video-assisted thoracoscopic (VATS) pulmonary wedge resection.Methods:Sixty-three patients scheduled for VATS pulmonary wedge resection in Shougang Hospital of Peking University from November 2020 to April 2022 were randomly assigned in 2 groups. All patients had a history of aspirin taking, patients in study group ( n=32) continued aspirin taking perioperatively, and patients in the control group ( n=31) stopped taking aspirin for 7 days before surgery and resumed taking 3 days after surgery. The volume of intraoperative blood lost, operation time, postoperative drainage volume, thoracic drainage tube placement time, postoperative hospital stay, postoperative thrombosis of lower extremity, perioperative cardiovascular and cerebrovascular events, and postoperative wound healing were documented and compared between the two groups. Results:There were no significant differences in age, gender, oral aspirin time, lesion location, lesion nature, localization, lesion size and underlying disease between the two groups (all P>0.05). All patients successfully completed the operation, and no patients switched to thoracotomy. The intraoperative blood loss in study group and control group was (27.72±12.86) ml and (31.35±13.81) ml ( t=1.08, P=0.283); the operation time was (61.16±10.24) minutes and (61.39±13.79) minutes, respectively ( t=0.08, P=0.940). There were no significant differences in postoperative thoracic drainage, drainage tube placement time, length of hospital stay, incidence of lower extremity thrombosis, incidence of cardiovascular and cerebrovascular events, and rate of poor wound healing between the two groups (all P>0.05). Conclusion:Perioperative administration of aspirin may not increase intraoperative and postoperative bleeding, and the incidence of operation-related complications in patients undergoing VATS pulmonary wedge resection.
