Perioperative stabilization of glucose levels in patients supported with total parenteral nutrition.

Fourteen nondiabetic and 6 diabetic patients were maintained on total parenteral nutrition during major surgery. Glucose levels when compared to preoperative levels increased during and after surgery although there were no significant differences between the diabetic and nondiabetic groups. Serum sodium demonstrated a slight decrease and serum potassium a slight increase after surgery in both groups. Total parenteral nutrition can be maintained during surgery provided glucose and electrolyte levels are observed and appropriate insulin doses are administered to diabetic patients.

Home tube feeding for long-term nutritional support.

Twenty-three adult patients with protein-calorie malnutrition were referred for outpatient tube feeding. Initial nutritional support with hypercaloric supplemented diets did not prevent further catabolism and weight loss, as the mean protein intake was 35.2 g/24 hr and the mean calorie intake was 844 cal/24 hr. Outpatient tube feeding was then initiated in deliver a mean of 78.5 g protein/24 hr and 2248 cal/24 hr. Patients on tube feeding demonstrated an increase of serum albumin and total body weight compared to diet therapy alone. The patient and family members were instructed in the technique of outpatient enteral feeding, which included instructions in feeding tube intubation, formula aspiration, and monitoring methods to prevent gastric aspiration and pooling. No major complications were observed. Home tube feeding was concluded to be a safe, efficient, and relatively inexpensive method of hyperalimentation for selected patients.

Metabolic abnormalities in patients supported with enteral tube feeding.

One hundred patients supported with enteral tube feeding were evaluated for biochemical abnormalities. The following metabolic complications were observed: hyperglycemia (29%), hypoglycermia (2%) hypernatremia (10%), hyponatremia (31%), hyperkalemia (40%) hypokalemia (8%), hyperphosphatemia (14%) hypophosphatemia (30%) hypomagnesemia (3%), hypozincemia (11%), and hypocupremia (3%). Because of the extensive range of biochemical problems, it is recommended that subjects on tube feeding be evaluated periodically for metabolic abnormalities.

Fluid and electrolyte replacement in the ultramarathon runner.

We studied three male runners during three separate ultramarathon races. Serial blood samples were tested for electrolytes, renal function, albumin, calcium, phosphorus, and magnesium. Two runners had aldosterone levels measured during the race and one runner had blood lactate levels measured. All runners ingested an isotonic fluid and electrolyte solution during the race. The runners consumed the solution without medical complications and maintained prerace body weights and hydration levels. Each runner maintained normal endocrine/metabolic parameters. We concluded that it is possible to maintain normal hydration and electrolyte states during a prolonged race, provided that sufficient fluid and electrolyte solutions are ingested.
