The incidence of reoperative median sternotomy for repeat cardiac surgery is increasing. Reoperative median sternotomy is associated with a higher morbidity and mortality than first-time cardiac surgery. ⋯ We report a new technique utilizing anterior sternal retraction that allows division of adhesions between the undersurface of the sternum and the heart and great vessels under direct vision. This technique enables the surgeon to minimize the risk of serious injury to these underlying structures during reoperative cardiac surgery.

Nosocomial pneumonia is frequent and is associated with high mortality in intubated mechanically ventilated patients. To determine whether there is a significant relationship between subclinical aspiration from nasogastric feeding and development of nosocomial pneumonia, we studied 24 ventilated patients who received nasogastric feeding. Endotracheal aspirates were tested twice daily for the presence of glucose using a glucose oxidase reagent strip. ⋯ The remaining five patients had nonbloody glucose-positive endotracheal aspirates and all developed nosocomial pneumonia. There was a significantly greater incidence of pneumonia among patients who had nonbloody glucose-positive aspirates than among patients without glucose-positive aspirates (p less than 0.001, Fisher's exact test). We conclude that subclinical aspiration of nasogastric feeding, as detected by nonbloody glucose-positive endotracheal aspiration, is associated with the development of nosocomial pneumonia.

Mitral valve repair for mitral regurgitation has been reported to have more favorable early and late results than mitral valve replacement. From July 1985 through July 1990, 63 patients have undergone valve repair at Good Samaritan Hospital. Twenty-two men and 41 women whose ages ranged from 34 to 81 years (mean 67.9 years) were treated. ⋯ There have been two valve-related late failures requiring reoperation. Based on this early experience, we conclude that valve repair compared with mitral valve replacement has a low operative mortality with good early results. Continued efforts to preserve native mitral valve function in the presence of mitral regurgitation appear justified.

We reviewed the management and clinical course of 21 patients with extrahepatic injuries to the portal triad seen over the past 11 years at a Level I trauma center. These represented only 0.21% of patients with multiple trauma admitted during this time. Portal triad injury was never specifically diagnosed preoperatively. ⋯ Complications necessitating reoperation or percutaneous drainage procedures were encountered in 8 of 10 surviving patients (80%). Injuries to the portal triad are uncommon, difficult to diagnose, and technically challenging. Mortality is most directly related to uncontrolled intraabdominal hemorrhage, and salvage requires rapid control of bleeding as the first treatment priority.
