Abstract

Objectives

We investigated the relationship between the perioperative nutritional status and postoperative walking ability in patients with hip fractures.

Methods

We included 246 surgically treated elderly patients with hip fractures who were ambulatory before the injury. Patients were divided into two groups: group A, who were able to walk at discharge, and group B, who were unable to walk at discharge. We pair-matched these two groups according to age, preoperative subdivided walking ability, and fracture site to form groups A′ and B'. The prognostic nutritional index (PNI; PNI = 10 × serum albumin (g/dL) + 0.005 × blood total lymphocyte count (/mm³)) before surgery and 1 day, 1 week, and 2 weeks after surgery and energy intake 1 and 2 weeks after surgery were compared.

Results

After adjustments for age, preoperative subdivided walking ability, and fracture site, there were 51 patients in group A' (mean age 84.6 years) and 51 patients in group B' (mean age 84.7 years). In group A'/group B′, PNI was 43.38/42.60 (P = 0.19) before surgery, 33.87/33.31 (P = 0.44) 1 day after surgery, 34.99/32.35 (P = 0.01) 1 week after surgery, and 37.33/35.69 (P = 0.15) 2 weeks after surgery. Energy intake was 1380.8/1203.1 kcal (P = 0.01) 1 week after surgery and 1382.0/1335.6 kcal (P = 0.60) 2 weeks after surgery.

Conclusions

PNI and energy intake at 1 week postoperatively were associated with early postoperative nutrition and the recovery of walking ability.

老年髋部骨折患者围手术期预后营养指数与术后步态功能之间的关系

方法我们纳入了 246 名接受过手术治疗的老年髋部骨折患者，这些患者在受伤前可以行走。患者被分为两组：出院时能行走的 A 组和出院时不能行走的 B 组。我们根据年龄、术前细分行走能力和骨折部位将这两组患者配对，形成 A′组和 B'组。比较了手术前、手术后 1 天、1 周和 2 周的预后营养指数（PNI；PNI = 10 × 血清白蛋白（g/dL）+ 0.005 × 血液总淋巴细胞计数（/mm³））以及手术后 1 周和 2 周的能量摄入量。结果经调整年龄、术前步行能力和骨折部位后，A′组有 51 名患者（平均年龄 84.6 岁），B′组有 51 名患者（平均年龄 84.7 岁）。在 A'/B′ 组中，术前 PNI 为 43.38/42.60 (P = 0.19)，术后 1 天为 33.87/33.31 (P = 0.44)，术后 1 周为 34.99/32.35 (P = 0.01)，术后 2 周为 37.33/35.69 (P = 0.15)。术后一周的能量摄入量为 1380.8/1203.1 千卡（P = 0.01），术后两周的能量摄入量为 1382.0/1335.6 千卡（P = 0.60）。
