Nasogastric hyperalimentation through a polyethylene catheter: an alternative to central venous hyperalimentation

We performed nasogastric hyperalimentation with polyethylene catheters and appropriate feeding solutions in 12 cachectic patients who had been referred as candidates for central venous hyperalimentation. Most patients had primary gastrointestinal disease. The duration of hyperalimentation averaged 31 days. Seven patients obtained rapid weight gain (average 0.3 kg/day) with the nasogastric hyperalimentation alone. An additional two were successfully repleted with the addition of parenteral fluids via peripheral veins. In the nine repleted patients, serum albumin rose by average 19%, 24-hr urine creatinine by average 21%, and triceps skinfold by average 46%. The nature of the weight gain in the nine successful cases was analyzed by the metabolic balance study technique. Average composition of the increment in weight was: 50% protoplasm, 48% extracellular fluid, 19% adipose tissue, and less than 1% bone. We conclude that nasogastric hyperalimentation can replace central venous hyperalimentation in a substantial proportion of patients now receiving the latter type of treatment.
