Efficacy of semi-solidification of enteral nutrients for postoperative nutritional management with a nasogastric tube.

Abstract

ABSTRACTPostoperative nutritional management with a nasogastric tube is often used to prevent malnutrition after oral and maxillofacial surgery. However, enteral nutrients (EN) may cause various complications due to their liquid formulation. In this study, we retrospectively evaluated the efficacy of semi-solid EN with a xanthan gum thickener through a nasogastric tube and examined patients’ complications, nutritional status, and quality of life. We established two groups: an L group (n=20) to which we administered liquid EN, and an SS group (n=20) to which we administered semi-solidified EN. The primary outcome was the occurrence of gastrointestinal complications. The secondary outcome was a change in nutritional status based on body weight and controlling nutritional status. The other outcome was the improvement in the patients’ quality of life, assessed by the administration time. During nutritional management with a nasogastric tube, the median daily administration time in the L group was 9.0 hours, and 9 patients experienced diarrhea. In the SS group, the median daily feeding time was 2.3 hours, and only 2 patients experienced diarrhea. Both groups exhibited a decrease in body weight while controlling nutritional status scores were maintained. Semi-solidification of EN may be useful for postoperative nutritional management after oral and maxillofacial surgery by reducing complications, maintaining nutritional status, and shortening administration time.
