摘要:
目的 分析老年股骨颈骨折患者的术前血清渗透压水平,并探讨其水平高低与住院时间以及并发症发生风险的关系。 方法 选取2020年1月—2021年12月于浙江中医药大学附属温州中西医结合医院接受治疗的120例股骨颈骨折患者作为研究对象,根据患者术前的血清渗透压水平将患者分为高水平组和低水平组,收集患者相关临床资料,同时进行为期1年的随访,记录患者全因死亡情况。采用Spearman相关性分析研究术前血清渗透压水平与患者住院时间、并发症等的相关性,采用Cox回归分析研究老年股骨颈骨折患者存活率的影响因素。 结果 41例患者纳入高水平组,79例患者纳入低水平组。术前血清渗透压水平与多维预后指数(MPI)得分(r=0.501)、住院时间(r=0.496)、术后并发症(r=0.383)的发生均呈正相关关系(P<0.05);Cox回归分析显示,性别(HR=17.404)、血清渗透压水平(HR=1.136)、MPI(HR=1.294)、格拉斯哥预后评分(GPS,HR=0.114)均是老年股骨颈骨折患者术后死亡的影响因素,在校正性别、MPI评分、GPS评分后的Cox回归分析中发现,术前血清渗透压水平(HR=1.071)是老年股骨颈骨折患者术后死亡的独立影响因素(P<0.05)。 结论 老年股骨颈骨折患者的住院时间、并发症发生情况与术前的血清渗透压水平和虚弱程度有关,术前进行血清渗透压水平检查,有助于围手术期进行更充分的液体管理,以降低术后的死亡风险。 Abstract:Objective To analyze the preoperative serum osmotic pressure level of elderly patients with femoral neck fracture, and to explore the relationship between its level and hospitalization time and the risk of complications. Methods A total of 120 patients with femoral neck fracture who were treated in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine Affiliated to Zhejiang University of Traditional Chinese Medicine from January 2020 to December 2021 were selected as the research object. According to the preoperative serum osmotic pressure level of patients, patients were divided into high-level group and low-level group. The clinical data of patients were collected and followed up for one year to record all-cause deaths. Spearman correlation was used to analyze the correlation between preoperative serum osmotic pressure level and hospitalization time and complications, and Cox regression was used to analyze the influencing factors of survival rate of elderly patients with femoral neck fracture. Results Forty-one patients were included in the high-level group and 79 in the low-level group. Preoperative serum osmotic pressure level was positively correlated with MPI score (r=0.501), hospital stay (r=0.496) and postoperative complications (r=0.383), P<0.05. Cox regression analysis showed that gender (HR=17.404), serum osmolality level (HR=1.136), MPI score (HR=1.294) and GPS score (HR=0.114) were all influencing factors for postoperative death in elderly patients with femoral neck. Cox regression analysis after adjusting for gender, MPI score and GPS score found that preoperative serum osmolality level (HR=1.071) was an independent determinant of postoperative death in elderly femoral neck patients (P<0.05). Conclusion The hospitalization time and complications of elderly patients with femoral neck fracture are related to the preoperative serum osmotic pressure level and the degree of weakness. Preoperative examination of serum osmotic pressure level is helpful for more adequate perioperative fluid management to reduce the risk of postoperative death. -
