The provision of adequate nutrition to hospitalized patients with exceptional caloric requirements has been a problem until the recent advent of intravenous hyperalimentation. With total parenteral nutrition (TPN), the nutritional needs of any patient can be met by infusion. TPN solution is hypertonic, and administration requires central venous cannulation. The subclavian vein is usually chosen as route of access to the superior vena cava. Strict aseptic technique must be used in inserting the catheter and making up and administering the solution. TPN is not without risk. Infection is always a possibility, as are metabolic alterations, such as electrolyte imbalance, fluid overload, osmotic dehydration, and essential fatty acid deficiency.

On the basis of recent pathophysiological data and clinical observations in three patients, this paper draws attention to the commonly neglected importance of postoperative hypoproteinemia as the cause of an edema of the intestinal wall with a consequent "interstitial" paralytic ileus. The characteristic features of this syndrome are its onset between the third and the eighth postoperative day; the absence of other known causes of intestinal hypomotility; the benign, but protracted course without treatment; and the therapeutic success achieved by the correction of a hypoproteinemic fluid overload with concentrated albumin and a diuretic. In addition, parenteral hyperalimentation and Rheomacrodex-Sorbit may be indicated, but the hypoproteinemia should at any rate be corrected.

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.

Twenty-eight patients underwent pelvic exenterations for gynecologic malignancies between June 1986 and June 1989. The postoperative fluid and electrolytes were managed by one of two regimens. One group of 10 patients was given concentrated 25% albumin infusion for the first 16 hr after surgery in addition to maintenance intravenous crystalloid solution according to ideal body weight. The second group of 18 patients received only a standard crystalloid solution. The albumin infusion group was found to have a more stable postoperative course as evidenced by less fluid boluses (P less than 0.01), fewer electrolyte bolus requirements (P less than 0.01), and easier management of blood pressure and urine output. There was a 50% decrease in total fluid requirement, a higher mean right atrial pressure (P less than 0.05), and a lower maintenance intravenous fluid rate (P less than 0.01). As a consequence, central hyperalimentation was started earlier (P less than 0.01) and the albumin infusion group left the Intensive Care Unit sooner than the non-albumin infusion group. There was not a single instance of clinical fluid overload with this slow infusion technique. Thus, concentrated albumin infusion was beneficial in the acute fluid management of these difficult patients.

One hundred nineteen patients were entered onto a randomized trial of the role of intravenous hyperalimentation (IVH) in patients with small-cell lung cancer. IVH was given during the first 30 days of induction chemotherapy to 54 patients. IVH did not effect any improvement in response or survival from therapy. In view of the lack of benefits from IVH, an analysis was made of the toxicities suffered by the 54 patients receiving IVH as well as any effects IVH might have made on chemotherapy-induced toxicity. Toxicities observed included mechanical difficulties with the catheter leading to temporary or permanent discontinuation of the IVH (11 patients), subclavian vein thrombosis (one patient), sepsis in nine patients v none of the 62 control patients, fluid overload (27 patients), hyponatremia (25 patients), and hyperglycemia requiring insulin (13 patients). Patients receiving IVH had higher granulocyte counts on days 14 and 21 of the first cycle of chemotherapy. Analysis shows that this difference is likely caused by fever and infection associated with IVH rather than any nutritional effect on granulopoiesis. In this population of patients, IVH had significant complications but did not ameliorate chemotherapy-induced toxicity and it did not effect any clinical benefit. Future studies of adjunctive nutritional therapy must consider the significant risk in this older population and must limit IVH volume or exclude patients with even mild compromise in cardiovascular functions. Further, any new trial must have a significant rationale for adjunctive use to justify the potential risks.
