Thirty-one abdominal fascial wound dehiscences occurred in 2,761 patients undergoing major abdominal surgery during a 5-year period (1%). Twenty-two specific local and systemic risk factors were analyzed and compared with the risk factors of a control group of 38 patients undergoing similar procedures without dehiscence. Through multivariate analysis, each factor was assessed as an independent statistical variable. Significant factors (p less than 0.05) were found to include age over 65, wound infection, pulmonary disease, hemodynamic instability, and ostomies in the incision. Additional systemic risk factors that were found to be significant included hypoproteinemia, systemic infection, obesity, uremia, hyperalimentation, malignancy, ascites, steroid use, and hypertension. Risk factors not found to be important independent variables included sex, type of incision, type of closure, foreign body in the wound, anemia, jaundice, and diabetes. When dehiscence and control groups were combined, 30% of patients with at least five significant risk factors developed dehiscence, and all the patients with more than eight risk factors developed a wound dehiscence. There was an overall mortality of 29%, which was directly related to the number of significant risk factors. The co-existence of 9 risk factors portended death in one third of the patients, and all the patients with more than 10 risk factors died.

Perforation of the colon in the immunocompromised patient is a catastrophic and usually fatal event. The immunocompromised patient, like all patients, may suffer from the more common causes of colonic perforation, including diverticulitis, chronic inflammatory bowel disease, presence of a foreign body, and trauma. There also appears to be in these patients the unusual occurrence of spontaneous perforation, particularly in patients with renal allografts or on dialysis. In a retrospective multi-hospital review, 10 cases of apparent spontaneous perforation were found. The pathogenesis is unclear, but predisposing factors include immunosuppressive medications, uremia, discrete colon ulcerations, and fecal impaction. The reported mortality rate approaches 100 percent due to delayed recognition and impaired host defense mechanisms. In our patients, mortality was 40 percent. We attribute this improved survival to prompt surgical intervention and aggressive postoperative management, including daily dialysis, parenteral hyperalimentation, broad-spectrum antibiotics, and a high index of suspicion for ongoing sepsis with early repeat exploration.

Total parenteral nutrition was attempted by using the peritoneal route. In this way it was possible to convey to the patients all elemental nutrients used in hyperalimentation. Three patients were studied while treated for an episode of catabolic stress in the course of acute or chronic uremia. Adequacy of treatment was controlled by measuring urea generation rates, plasma concentrations of 3-methyl-histidine, glucose disappearance from dialysate and kinetics of lipid particles removal from plasma. The data collected demonstrate that peritoneal hyperalimentation is is feasible for adequate for clinical purposes.

The metabolic and nutritional effects of long-term parenteral and enteral nutrition were studied in two infants and one child with severe growth failure due to chronic renal failure (two patients) and congenital nephrosis (one patient). Six periods of treatment were analyzed. Both the parenteral nutrition and continuous enteral nutrition were found efficient in enhancing growth and correcting the metabolic abnormalities of uremia. The beneficial effects of this intensive nutrition were smaller in congenital nephrosis, although growth accelerated. Nitrogen balance studies confirmed effective nutrient utilization. The serum levels of calcium and phosphate were normalized as anabolism was achieved in the uremia. In fact, the rapid development of severe hypophosphatemia in one of the patients proved that the "fatal hyperalimentation syndrome" appears to be a specific threat in parenteral nutrition applied in uremia.

We evaluated amount and composition of amino acids in supplementation of hyperalimentation from the standpoint of whether it may improve nutrition and/or reduce the indexes of uremia such as BUN. Rats with established uremia, by 5/6 nephrectomy, were treated with various isocaloric solutions containing different amount of essential amino acids and histidine (EAA) or standard amino acids (SAA) which were formulated to provide Cal/N ratios of 300, 600, and 900. The BUN was lower and the nutritional index was better in rats infused with EAA compared with those administrated SAA, while severe distortion of plasma amino acid concentration, hyperammonemia, and fatty liver were observed at the Cal/N 300 condition. Rats infused with SAA gained positive nitrogen balance at the condition of Cal/N 300; however, plasma amino acid distortion was still observed. These results indicate that administration of EAA alone for treatment of renal failure needs high-calorie and low-nitrogen conditions such as Cal/N 600 for avoiding complications. Administration of standard amino acid solution is safe and nutritionally effective in the Cal/N 300 condition, but there are a few problems concerning nitrogen availability and plasma amino acid pattern.
