One of the most contentious issues in surgery is the use of prophylactic topical antibiotics to prevent wound infection [1]; cardiac surgery is no exception. Despite regular use of prophylactic intravenous antibiotics, postoperative mediastinitis occurs in a significant number of patients undergoing open heart surgery through median sternototmy. This major complication plagues the most commonly used incision in cardiac surgery, and is associated with a mortality rate as high as 47%. Staphylococcus aureus or S epidermidis are isolated in as many as 70% of the cases. Therefore, prophylactic instillation of antigram-positive antimicrobials during wound closure may reduce the risk of mediastinitis. This concept has indeed been tested in a previous prospective, randomized, controlled study; Vander Salm and associates [2] found that topical vancomycin applied during wound closure after median sternotomy was associated with a significant reduction in the rate of sternal wound infection (from 3.6% in the control group to 0.45% in the treatment group). We found sub-MIC levels . . . [Full Text of this Article]
