Abstract

MiniA new multimodal nutritional management (MNM) protocol was applied for patients receiving primary lumbar spine surgery. The MNM protocol effectively reduced ALB infusion, the incidence of electrolyte disorders and LOS, increased the postoperative levels of ALB and electrolyte, without increasing the rate of postoperative complications.Study Design.A prospective, randomized, controlled trial.Objective.The purpose of this study was to evaluate the clinical effect and safety of a new multimodal nutritional management (MNM) protocol for patients receiving primary lumbar spine surgery.Summary of Background Data.Poor nutritional status is common in the perioperative period in primary lumbar spine surgery, and may impede recovery after surgery.Methods.A total of 187 patients were included in this prospective randomized controlled trial. They were randomly assigned to the MNM group or the control group. Albumin (ALB) infusion, postoperative ALB level, electrolyte disorders, postoperative electrolyte levels, transfusion rate, postoperative hemoglobin (Hb) level, length of stay (LOS), and complications were compared between the groups.Results.Compared with the control group, the rate and the total amount of ALB infusion were lower in the MNM group, and the postoperative level of ALB in the MNM group was higher on the first postoperative day (POD1), and the third postoperative day (POD3). The incidence of hypokalemia, hyponatremia, and hypocalcemia were lower in the MNM group. In the MNM group, the postoperative levels of sodium, potassium, and calcium were higher than the control group. The transfusion rate was similar between the two groups. The Hb level was similar between the two groups on POD1, but was higher in the MNM group on POD3. LOS in the MNM group was shorter than in the control group. The incidence of wound drainage was lower in the MNM group. No statistical differences were observed regarding surgical complications between the two groups.Conclusions.The MNM protocol effectively reduced ALB infusion, the incidence of electrolyte disorders, and wound drainage, increased the postoperative levels of ALB, sodium, potassium, and calcium, and reduced the LOS without increasing the rate of postoperative complications.Level of Evidence.2
