Objective: To elucidate the effect of bone wax on postoperative bleeding, infection and wound healing.
Methods: This study included two independent groups, consisting of 94 patients who were treated with bone wax and 90 patients who received nothing after median sternotomy and just before sternal closure. Demographic and postoperative data were recorded. Both groups were compared with respect to the amount of postoperative drainage, blood transfusion requirement, re-exploration because of bleeding, and mortality rates.
Results: Demographic measurements did not differ between the groups. In the first two months of the postoperative period, mediastinitis was not seen in any of the patients in both groups. Superficial wound infection was detected in six patients (6.4%) in Group A. Eight patients (8.9%) suffered from superficial wound infection in Group B (p >0.05). In the first postoperative 24 hours, the average amount of postoperative drainage was 536.89 ml in Group A, whereas it was 529.67 ml in Group B (p >0.05). Three patients in both groups died in the early phase of the postoperative period (p >0.05).
There was not any statistically significant difference between groups considering bleeding quantity, mortality, re-exploration, amount of blood used and deep sternal infection.
Conclusion: Bone wax does not reduce bleeding on sternal sides. No evidence was found that application of bone wax causes deep sternal infection in patients having median sternotomy for coronary bypass surgery.
