Permissive underfeeding in post-operative patients: results of a prospective, randomized, controlled clinical trial / 中国普通外科杂志

Objective To evaluate permissive hypocaloric intake in postoperative patients by a prospective, randomized, controlled trial. MethodsForty-two postoperative patients were randomly assigned to receive 117kJ?kg~ -1?d~ -1in control group, and 75kJ?kg~ -1?d~ -1in experimental group intravenously. Blood routine, liver and renal functions were measured one day before and day 1, 3, 5 post operation. Blood glucose level, insulin intervention, infectious complications, hospital stay, and relevant cost were also evaluated. ResultsHypocaloric intake in the experimental group post-operatively did not influence the hemoglobin level, liver function, and other indicators in the serum. The fasting blood glucose and glucose levels after infusion, as well as the volume of insulin intervention were significantly higher in the control group during 4 days of parenteral nutrition. Experimental group had lower relevant hospital cost, while two groups had similar duration of hospital stay. ConclusionPermissive hypocaloric intake shortly after surgery does not influence the patient nutritional status, besides it avoids to some extent the hyperglycemia, reduces the need for insulin intervention .
