Randomized Controlled Trial Clinical TrialOncotic pressure, albumin and ileus: the effect of albumin replacement on postoperative ileus.
The effect of decreased colloid oncotic pressure, as seen in hypoalbuminemia and hypoproteinemia, upon intestinal function has been well delineated in the surgical literature. Patients undergoing abdominal aortic aneurysm resection or aortoiliac or aortofemoral bypass grafts are almost uniformly hypoalbuminemic postoperatively; with these two facts in mind, a prospective, randomized clinical study was undertaken to identify the role of serum albumin concentration on the length of postoperative ileus in this population. The main hypothesis was that patients whose albumin levels dropped below 3.5 gm/dL would have a more prolonged postoperative hospital course as a result of delay in return of bowel function when compared with those patients in whom the low albumin levels were exogenously acutely replenished to > 3.5 gm/dL. ⋯ Return of bowel function was measured by the postoperative day that flatus was documented, as well as the postoperative day oral intake was resumed. Mean values were determined for each group, and t tests did not reveal a significant difference in postoperative day of flatus (AR mean = 4.06 days, NR mean = 4.16 days) or postoperative day of oral intake (AR mean = 4.0, NR mean = 3.75). Additional comparisons between the groups involving the number of postoperative days until a regular diet was begun (AR mean = 6.06, NR mean = 5.48) and length of postoperative hospital stay (AR mean = 9.16, NR mean = 8.43) failed to reveal significant differences.(ABSTRACT TRUNCATED AT 250 WORDS)

It is widely assumed that infections are the principal cause and primary outcome determinant of the syndrome of Multiple Organ Failure (MOF) in critically ill patients. Infections are frequent in these patients, but the prevention and treatment of infections may not influence the course of MOF. This study tested the hypothesis that infections play a decisive role in the outcome of MOF. ⋯ Thirty four (47%) had a documented source of infection, 37 (51%) had positive blood cultures, and all had sepsis. Hospital mortality was 66 percent (48 of 73 patients). Death could not be predicted by bacteremia (P > 0.25), nor by the presence of an infectious source (P = 1.0), but was strongly associated with severe sepsis (P < 0.0005).(ABSTRACT TRUNCATED AT 250 WORDS)

Penetrating injuries to the neck: a safe, selective approach to management.
The most appropriate management of patients with penetrating injuries to the neck remains a controversial issue. In order to determine the safety and efficacy of a selective approach to the management of such patients, a retrospective review of our experience with penetrating injuries to the neck at Northwestern Memorial Hospital over the past 5 years since the designation as a Level I trauma center was undertaken. A total of 30 patients fulfilled entry criteria. ⋯ Endoscopy was used infrequently. The mortality rate was 13.3 per cent, there were two negative cervical explorations, and there were no missed injuries. The results support the application of a selective approach to the operative management of penetrating injuries to the neck.

ReviewFatal cerebral gunshot wounds: factors influencing organ donation.
Patients with clinical brain death following head injury are important potential cadaveric organ donors. We analyzed our series of cranial gunshot wounds with particular attention to the frequency and patterns of organ donation after fatal injuries. Sixty-six patients with gunshot wounds to the head, including 59 with intracranial involvement (43 male, average age 26 years) were seen during a 4-year period. ⋯ Of the 39 patients who died, 28 met standard criteria for brain death, and nine of these went on to organ procurement. Thirteen families refused donation, and six patients were not harvested for reasons including old age, pregnancy, suspicion of AIDS, coroner refusal, and failure to pursue consent. Principles essential to maximal organ retrieval include: 1) Recognition that patients suffering cerebral gunshot wounds represent potential organ donors and that certain factors are predictive of mortality; 2) Critical care/trauma team approach with standardized management and timely declaration of brain death; 3) Early search for family members and prompt notification of organ procurement agencies; 4) Sensitivity to cultural issues influencing donation; and 5) Programs to increase public awareness of organ donation.
