Abstract

Objective: Postoperative deep sternal wound infection with dehiscence carries a high mortality rate, a high morbidity rate, and a poor cure rate. We developed a standard protocol of care to treat this complication, achieving primary closure and cure of the infection. Methods: From January 1, 1981, through May 31, 2005 (24 years 5 months), we treated 114 patients with dehiscence and mediastinitis. The diagnosis was made from 4 to 56 days (mean, 14.5 days) after surgery. Mean age was 64.3 years (range, 38-84 years); 79 (69%) were obese, and 48 (42%) had diabetes. Ten had previous attempts (1-4) of repair with other methods. Treatment entailed (1) debridement without removal of bone, (2) bilateral dissection of skin and subcutaneous tissue as one layer, (3) implantation of a staggered double-tube irrigation-suction system posterior and another one anterior to the sternum, (4) lateral reinforcement of the sternum and reclosure with a double wire, and (5) a single-layer closure of the subcutaneous tissue and skin. Results: Of 114 patients, 109 (96%) had mediastinitis, positive for Staphylococcus species in 101 (92.6%). The cure rate was 98% (112/114); hospital stay was 14 days (range, 12-16 days), with no deaths. Conclusions: Use of this standard protocol is effective and highly recommended. It spares the sternum, cures the infection, and leaves the patient physically functional without the use of soft tissue flaps.
