Study DesignA prospective randomized controlled trial.ObjectiveThe 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 DataPoor nutritional status is common in the perioperative period in primary lumbar spine surgery, and may impede recovery after surgery.MethodsA 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 level, length of stay (LOS), and complications were compared between the groups.ResultsCompared 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, and the third postoperative day. 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 hemoglobin level was similar between the two groups on first postoperative day, but was higher in the MNM group on third postoperative day. 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.ConclusionThe 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 Evidence2.
