Experience with long-term intravenous hyperalimentation in the hospital and at home in one patient over a 22-month period is reported. After multiple operative procedures the patient was left with only her stomach, duodenum, and 5 cm of the proximal part of the jejunum. During a 12-month period in the hospital, despite many life-threatening complications and with high-output intestinal fistulas, her weight increased from 40.7 kg (90 lb) to 70.1 kg (155 lb) on intravenous hyperalimentation therapy. During the past ten months, the patient has managed her intravenous feeding at home. A silicone elastomer catheter inserted into her superior vena cava through her facial vein has been used for the past ten months with no catheter sepsis. Although costly, home intravenous alimentation seems justifiable in selected patients because of the possible feasibility of bowel transplants in the near future.

From July 1969 to December 1975, 86 patients with 100 fistulas required one or a combination of three modern nutritional aids: central intravenous hyperalimentation; the peripheral intravenous, lipid-amino acid-carbohydrate system; and elemental, nutritionally complete liquid diets. Of the fistulas, 81 closed spontaneously, and in 11 operative closure was attempted; 89 fistulas healed. Eight patients died (9.3%). Before 1969, in an earlier comparable group of patients who had not received such nutrition, the mortality was 40.0%. Fistula drainage and sepsis were controlled. Abscesses were drained. Skin was protected. The most successful way of identifying the nature and origin of a fistula was by instillation of radiopaque liquid into the external opening. Prolonged fistula drainage occurred with distal bowel narrowing and inflammation; previous irradiation to the area; underlying granulomatous bowel disease; bowel adjacent to skin; and foreign bodies in the fistulous tract. Operative closure (resection) was necessary only for distal obstruction and wide breakdown or complete disruption of an anastomosis. Patients who did require operation were in a better nutritional state to withstand operation after receiving specialized nutritional support. Adequate calories and amino acids afforded healing and secretory and mechanical rest for the gastrointestinal tract.

Bacterial and fungal growth in 10% soybean oil emulsion (Intralipid) and 5% fibrin hydrolysate in 5% dextrose was studied at 4, 25 and 37 degrees C. Staphylococcus aureus, Streptococcus pyogenes, Str. fecalis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and Candida albicans were grown in broth at 37 degrees C, diluted in saline and inoculated into each of the two preparations as well as a mixture of the two. Growth was measured at 24, 48 and 72 hours. In 10% soybean emulsion, all bacteria except S. pyogenes multiplied, but in fibrin hydrolysate-dextrose solution the only organism of those studied to grow was S. aureus. In the hydrolysate-dextrose-lipid mixture, all organisms multiplied except S. pyogenes and P. aeruginosa. C. albicans grew in all solutions tested. While at 4 degrees C, organisms did not multiply. The fibrin hydrolysate-dextrose solutions given by infusion into a central vein for hyperalimentation have been shown to support predominantly fungal growth, and contamination of the solution and ultimately of the indwelling catheter is a constant hazard. Because both bacteria and C. albicans grew equally well in 10% soybean oil emulsion, its use as a caloric source when infused into a central vein may increase the occurrence of sepsis. When this emulsion is used to provide essential fatty acids or calories, it should be given via a peripheral vein, so that a central catheter will not be contaminated.

Candida sepsis has become one of the most common and dangerous forms of hospital acquired infection. The recommended drug for parenteral treatment of Candida sepsis is amphotericin B, however, its toxic effects preclude its usage in many patients, particularly in the presence of renal failure. A less toxic antifungal agent is 5-fluorocytosine. A patient with Candida albicans sepsis was treated successfully with 5-fluorocytosine by intravenous administration. The fungal infection developed during the course of acute renal failure, repeated surgical intervention, intravenous hyperalimentation, gastrointestinal bleeding and five months of antibiotic therapy. The clinical symptoms receded rapidly and cultures became sterile after one week of intravenous treatment. The predisposing factors, difficulties in prevention and diagnosis of fungal infection are discussed.

Intestinal fistulization following acute pancreatitis is a complication of abscess formation and may occur after initial surgical drainage. It should be suspected in anyone with protracted pancreatitis in whom an abdominal mass suddenly disappears or in whom gastrointestinal bleeding develops. Although transient improvement may occur, decompression will often be incomplete and will usually be followed by recurrent sepsis or severe life threatening hemorrhage. For this reason, spontaneous fistulization into the intestine does not eliminate the need for adequate surgical drainage. With fistulas into the colon, drainage should be combined with proximal diverting colostomy. Some duodenal fistulas may respond to abscess drainage and intravenously administered hyperalimentation, while others may require drainage plus conversion from a side to an end fistula.

Acute renal insufficiency after cardiopulmonary bypass can lead to a significant morbidity from fluid overload and electrolyte disturbance, impede pulmonary gas exchange, and postpone weaning from mechanical ventilation. The limitations placed on free water intake result in severe restriction of nutrition while diuretic therapy causes electrolyte imbalance. Artificial renal support either in the form of peritoneal dialysis or hemodialysis may be complicated by sepsis and hemodynamic instability. We reviewed our experience with the use of continuous arteriovenous hemofiltration, an extracorporeal technique for removal of solutes, toxins, and water in critically ill patients with cardiac failure complicated by acute renal insufficiency and hemodynamic instability after cardiopulmonary bypass. Ten infants and children with renal insufficiency caused by low cardiac output had continuous arteriovenous hemofiltration instituted for indications including sepsis, volume overload, oliguria for more than 24 hours nonresponsive to diuretic therapy, and the need for hyperalimentation. All were supported by mechanical ventilation and receiving high-dose inotropic support. Arterial and venous vascular access was successfully obtained by cannulation of the femoral artery and vein in nine patients. Anticoagulation of the circuit was achieved with heparin infusion (6 to 20 micrograms/kg/hr) and monitored by measurement of activated clotting time. The continuous arteriovenous hemofiltration circuit was replaced if there was clot formation, or at 3 days after placement. Dialysis solution (Dianeal) 1.5% or 0.5% was infused as prefilter dilution. With the use of continuous arteriovenous hemofiltration, 20 to 100 m/hr of ultrafiltrate was removed, which allowed correction of hypervolemia, and caloric intake increased from 13.5 kcal/kg/day to 79.5 kcal/kg/day. Continuous arteriovenous hemofiltration was maintained between 5 hours and 8 days and was well tolerated in all patients. Serum urea and creatinine levels declined during continuous arteriovenous hemofiltration. We conclude that continuous arteriovenous hemofiltration is a safe and effective method for fluid and electrolyte homeostasis and that it thus allows hyperalimentation in infants and children after cardiac operations.

Six hundred fifty-four peripheral Teflon catheters in 303 pediatric intensive care unit patients were examined to determine complication rates and associated risk factors. Phlebitis, extravasation, and bacterial colonization occurred at rates of 13%, 28%, and 11%, respectively. Logistic regression of factors that increased phlebitis risk revealed infusion of hyperalimentation (odds ratio 2.9) or lorazepam (odds ratio 2.2) and catheter location (odds ratio 2.9) as the most important determinants of phlebitis risk. Age (less than or equal to 1 year, odds ratio 2.0), catheter time in situ (less than or equal to 72 hours, odds ratio 2.1), and infusion of antiepileptics (odds ratio 2.1) were the most important determinants of extravasation. Catheters were colonized most frequently with coagulase-negative Staphylococcus (51/54). Sepsis attributable to catheter colonization occurred in 1 patient. Duration of catheter placement (greater than or equal to 144 hours, odds ratio 5.8) was an important determinant of catheter colonization. Colonization risk increased from 11% in catheters that were in situ for 48 to 144 hours to 34% for catheters that were in for longer than 144 hours. Infusion of diazepam (odds ratio 11.0) or lipid emulsions (odds ratio 2.5) and age (less than or equal to 1 year, odds ratio 2.2) were also important determinants of colonization risk. Replacing catheters in critically ill children every 72 hours would not decrease phlebitis, bacterial colonization, or catheter-induced sepsis and could increase extravasation risk. Catheters can be safely maintained with adequate monitoring for up to 144 hours in critically ill children.

This report concerns 59 infants and children with short bowel syndrome, most commonly caused by necrotizing enterocolitis in this study. Resection of atretic or gangrenous bowel was performed in 53 patients, tapering enteroplasty and primary anastomosis was performed in 13 patients, and temporary enterostomies were performed in 40 patients. Second-look laparotomy was useful in two of four cases of questionable bowel viability. The ileocecal valve was resected in 32 patients and remained intact in 27. The mean length of the remaining bowel was 58.4 cm. All patients received total parenteral nutrition and early enteral feedings. Home hyperalimentation was attempted when 50 per cent of the calorie intake was enteral. Intestinal adaptation required from 3 to 14 months. Frequent setbacks were related to catheter sepsis, rotavirus infection, carbohydrate intolerance, and liver dysfunction. The overall survival rate was 80 per cent with mortality due to sepsis associated with total parenteral nutrition and liver failure.

To determine factors associated with risk for umbilical catheter-related sepsis, we studied neonates with one or more catheters in place for more than 3 days. Among 225 infants with 357 umbilical catheters, catheter-related sepsis occurred in 14 infants (6%). Catheter-related sepsis occurred in 5% of infants with umbilical arterial catheters and in 3% of infants with umbilical venous catheters. Staphylococcal species accounted for 71% of cases of catheter-related sepsis. Multiple logistic regression analysis revealed that very low birth weight and longer duration of antibiotic therapy were significantly associated with risk for umbilical arterial catheter-related sepsis. Increased risk for umbilical venous catheter-related sepsis was best predicted by the simultaneous occurrence of higher birth weight and infusion of hyperalimentation solution. Catheter duration correlated with duration of antibiotic therapy and with infusion of hyperalimentation solution for both types of catheters; however, in the multivariable analysis, duration of catheterization was not found to be a significant independent predictor of risk for catheter-related sepsis for either type of catheter.

The traditional approach to the care of the gastrointestinal tract in the intensive care unit has been one of neglect. However, recent evidence has linked enteric flora to the generation of clinical sepsis in the absence of other infectious foci. The role of the bowel as an efficient barrier to the invasion of its own flora is addressed in this paper. A variety of insults disrupt the integrity of the barrier function of the gut, allowing the entry of bowel organisms or endotoxins, or both, into the portal and systemic circulatory systems. In animal and early clinical studies, a number of interventions, aimed at altering the enteric flora and enhancing the bowel's barrier function, have been shown to modulate the host's resistance to different insults and may even improve clinical outcome. Such interventions include maintenance of enteral feeding, glutamine supplementation of hyperalimentation solutions and selective bacterial decontamination of the bowel.
