Postoperative intermittent pneumatic compression for preventing venous thromboembolism in Chinese lung cancer patients: A randomized clinical trial

Le résumé fourni par la source

Abstract Background Postoperative lung cancer patients belong to the high-risk group for venous thromboembolism (VTE). The standardized preventive measures for perioperative VTE in lung cancer are not perfect, especially for the prevention and treatment of catheter-related thrombosis (CRT) caused by carried central venous catheters (CVCs) in lung cancer surgery. Patients and Methods: This study included 460 patients undergoing lung cancer surgery in the Department of Thoracic Surgery, First Affiliated Hospital, Army Medical University from July 2020 to June 2021. Patients were randomized into two groups, and intraoperatively-placed CVCs would be carried to discharge. During hospitalization, the control group was treated with low-molecular-weight heparin (LMWH) and the experimental group with LMWH + IPC. Vascular ultrasound was performed at three time points which included before surgery, before discharge, and one month after discharge. The incidence of VTE between two groups were studied by Log-binomial regression model. Results CRT occurred in 71.7% of the experimental group and 79.7% of the control group. The multivariate regression showed that the risk of developing CRT in the experimental group was lower than in the control group (Adjusted RR = 0.889 [95%CI 0.799–0.989], p = 0.031), with no heterogeneity in subgroups (P for Interaction > 0.05). Moreover, the fibrinogen of patients in the experimental group was lower than control group at follow-up (P = 0.019). Conclusion IPC reduced the incidence of CRT during hospitalization in lung cancer patients after surgery. Clinical Trial Registration: No. ChiCTR2000034511
