Forty-nine war casualties with penetrating cardiac wounds were treated at the Hôtel-Dieu de France University Hospital between April 1975 and December 1987. All the wounds were caused by high-velocity missiles. An aggressive approach was utilized. ⋯ Overall survival was 63% (31/49). No intracardiac injuries were diagnosed in survivors, and no cardiac reoperations were required. Careful analysis of the trajectory of the missile or missiles and a portable chest roentgenogram were the most important factors for diagnosing a penetrating wound to the heart and for predicting potential associated injuries.

Traumatic asphyxia secondary to a crush injury of the chest is characterized by craniocervical cyanosis, subconjunctival hemorrhage, and severe vascular engorgement of the head and neck. These signs are believed to be due to high venous pressures causing stasis and capillary rupture. ⋯ The lower torso seems to be protected, and previously this was thought to be due to its superior system of valves. We present here ultrasonographic evidence that the inferior vena cava is compressed or obliterated during a Valsalva maneuver, and propose that this compression protects the lower torso during traumatic asphyxia.

The ability to predict cardiac output (CO) before termination of cardiopulmonary bypass (CPB) allows identification of potential complications once the patient is off bypass. We have previously demonstrated that CO early after CPB can be reliably predicted by a plot of venous oxygen saturation at various flow rates on CPB, based on in-line monitoring of venous oxygen saturation. In this study, we evaluated a simplified technique for predicting CO with a series of 50 patients on CPB. ⋯ The simplified CO prediction was compared with the thermodilution CO immediately after CPB. The simplified technique reliably predicted CO early after CPB compared with the thermodilution technique. The simplicity and reliability increase the clinical value of the CO prediction.

Case Reports
Transpericardial bronchial closure with omentopexy for postpneumonectomy bronchopleural fistula.
We report a case of successful closure of a postpneumonectomy bronchopleural fistula by means of the transpericardial approach with omentopexy through a median sternotomy incision. This method minimizes problems of infection, healing, and pulmonary function.
