Necessity of Bone Wax Stanching Bleeding at Sternal Edge in Patients With Cardiac Surgery by Median Sternotomy / 中国循环杂志

ABSTRACT

Objective: To explore the necessity for application of bone wax stanching bleeding at sternal edge in cardiac surgery by median sternotomy. Methods: A total of 445 patients who receive cardiac surgery by the same surgeon performing median sternotomy in our hospital from 2011-01 to 2014-12 were studied. According to application of bone wax stanching bleeding, the patients were divided into 2 groups: Bone wax group,n=210 and Non-bone wax group,n=235. Re-thoracotomy for hemostasis, 12 h, 24 h and total draining volume after the operation and time of closing incision were compared between 2 groups. Results: There were 2 patients and 1 patient received re-thoracotomy for hemostasis in Bone wax group and Non-bone wax group respectively, which was not related to bone marrow cavity bleeding. In Bone wax group and Non-bone wax group, the draining volume at 12 h post-operation were (451 ± 240) ml vs (483 ± 238) ml, at 24 h post-operation were (615 ± 304) ml vs (639 ± 285) ml and the total volume were (842 ± 467) ml vs (842 ± 364) ml, allP>0.05; the time of closing incision were (68.0 ± 23.0 ) min vs (66.0 ± 19.0 ) min,P>0.05; the total transfusion rates were 21% vs 19%,P>0.05. Conclusion: Application of bone wax at sternum edge could neither affecting the drainage nor the speed of closing incision in cardiac surgery and therefore, it might be given up.
