Abstract
BACKGROUND: Much attention has been given to venous thromboembolism (VTE) disease, and many guidelines for prophylaxis have been published. However, there are few published data on patients who underwent thoracotomy. This study is to compare the effect of low molecular weight heparin (LMWH) combined mechanical approaches with mechanical approaches alone in prevention of VTE in the post thoracotomy cancer patients. METHODS: This study used a prospective, randomized-controlled design. Patients with cancer who were scheduled for thoracotomy were divided into two groups: group A and group B. In group A, patients were given intermittent pneumatic compression (IPC) and elastic stockings (ES) postoperatively. Additionally, at 24 hours post-operation, patients were subcutaneously injected with LMWH calcium (nadroparin calcium; GlaxoSmithKline, China) for 7 days. In group B, patients were only given postoperative IPC and ES. The primary end points were incidence of pulmonary embolism (PE), deep vein thrombosis (DVT), and the PE severity index (PESI) of PE patients. The secondary end points were hemoglobin (HGB), platelet (PLT), D-dimer, the PO2/FiO2 ratio (P/F) at postoperative day (POD) 7, the chest drainage time (CDT) and the length of stay (LOS) in hospital after operation. RESULTS: A total of 90 patients were included in the final data analysis (40 patients in group A and 50 patients in group B). At POD7, the incidence of PE, DVT and PESI was 17.50%, 5.00% and 102.14±9.87, respectively, in group A. And 8.00%, 8.00% and 97.00±4.24, respectively, in group B. There were no significant differences between two groups (all P values were >0.05). There were no significant differences of HGB, PLT, D-dimer and P/F between two groups at the 7th day post operation (all P value >0.05). CONCLUSIONS: LMWH combined mechanical prophylaxis did not significant reduced the rate of VTE in thoracotomy cancer patients.
