Mediastinitis remains a serious complication of median sternotomy which requires prompt and aggressive surgical management. Debridement and closed irrigation has been the conventional mode of treatment. Failure to respond results in open drainage and delayed healing with its associated increased morbidity and mortality. ⋯ Sternal dissolution, the presence of anaerobic organisms, large volumes of purulent and necrotic material, however, were responsible for continued mediastinitis and further sternal dehiscence. Open irrigation and delayed closure with muscle flaps should be reserved for these patients and appears to decrease significantly morbidity and length of hospital stay. Surgical debridement and closed irrigation, however, remains the primary method of treatment of the less virulent forms of mediastinitis following median sternotomy.
