Abstract
We evaluated the postoperatively nutritional status in 21 patients (5 males; 16 females) with maxillofacial deformity who were given a low residue diet. The energy content of the diet was 1 kcal/ml. We administered 1, 000 kcal/day on the first day, and increased the dose by 200 kcal/day daily until a full strength of 2, 000 kcal/day was achieved. The diet was then given for 14 days with a naso-gastric feeding tube. We examined blood chemistry, blood count, and nitrogen balance and measured body weight on preoperative day 1 and on postoperative days 1, 7, and 14.On the first day, total protein, albumin, and rapid turnover protein decreased because of the surgical damage. These variabled showed improvement on day 7. On day 14, 20 patients (95%) had improved nutritional status, as compared with their preoperative status. The nitrogen balance became positive in all patients by day 7. We could not find any clinical problems, including changes in body weight and laboratory examinations for liver or renal function, serum electrolyte levels, and blood counts. As for side effects, 4 patients had diarrhea, but did not have to decrease the quantities of their low residue diet. All patients showed a rapid improvement in their nutritional items without side effects under this nutritional program.Low residue diet Sanet-V® was useful for the postoperative nutritional management of patients with maxillofacial deformity and the resolution of surgical damage.
