Sternal protection technique for open chest management.

On some occasions, postoperative mediastinal bleeding or right ventricular failure forces surgical teams to pursue a strategy of open-chest management and delayed sternal closure. One notable source of postoperative bleeding is the sternum, either due to medullar bleeding or bone margin oozing, which may be difficult to control. Furthermore, in cases with right ventricular failure or dilatation needing an open-chest strategy, sternal margins might erode and injure the right ventricular anterior wall. We propose a simple but effective sternal protection technique during open-chest management and further delayed chest closure. Using leftover tubing from the cardiopulmonary bypass circuit or a mediastinal 32 Fr drain, both sternal margins are covered and secured with sutures. Moreover, in case of profuse bleeding, a thrombin-derived haemostatic agent can be applied between the bone marrow and the tube for an additional level of haemostasis. The sternal wound is isolated with a latex membrane and covered with transparent sterile adhesive sheets to achieve vacuum sealing.
