title: Sternal wound complications. Management and results.
abstract: Of 4,124 patients undergoing median sternotomy for cardiac operations, 1.8% had sternal wound complications. These included wound drainage, skin separation, unstable sternum, and sternal dehiscence with or without infection. Septicemia and mediastinal abscess were found in all 19 patients who died. Incision and drainage of skin and subcutaneous tissue with frequent changes of dressing or irrigation (Method A) is recommended for those patients with (I) serosanguineous drainage only or (2) a stable sternum and superficial infection without systemic reaction. Surgical débridement of the sternum and mediastinum with reclosure followed by mediastinal irrigation via drainage tubes with 0.5% povidone-iodine solution (Method B) is recommended for patients with (1) a draining, unstable sternum, (2) infection involving the retrosternal space, or (3) infection causing a systemic reaction unresponsive to Method A. None of the eight patients in the latter group with more serious infections died when managed by Method B, and only one had recurrent infection. In contrast, of 28 patients of the latter group not treated with Method B, 11 died of infection-related causes and 13 returned with recurrent infection.
