Influence on Nutritional Index and Prognosis of Perioperative Individualized NutritionalIntervention for Elderly Patients with Nutritional Risk after Posterior Lumbar Interbody Fusion

Abstract

Objective To investigate the effect of perioperative individualized nutritional intervention on the changes of nutritional indicators and prognosis of elderly patients with nutritional risk after posterior lumbar interbody fusion. Methods From January 2018 to December 2019,a total of 181 elderly patients over 75 years old with posterior lumbar interbody fusion in Xuanwu Hospital Capital Medical University were included in this study.85 patients with≥3 points of NRS2002 were included in the intervention group,and 96 patients with0.05).The age of the intervention group was higher than that of the control group,the body mass index,intraoperative blood loss,preoperative serum total protein,albumin,prealbumin and hemoglobin levels were lower than those of the control group,and the operation time was shorter than that of the control group,with statistical significance(P0.05). Conclusion For elderly patients with nutritional risk,preoperative nutritional intervention can reduce the decline of postoperative nutritional indicators.
