摘要:

目的 探讨术前中性粒细胞/淋巴细胞比值(NLR)、尿酸(UA)和前列腺素E2(PGE2)联合检测对老年髋部骨折患者术后谵妄的预测价值。方法 选取2023年4—12月石家庄市第三医院行手术治疗的老年髋部骨折患者120例,收集所有患者的临床资料,检测术前NLR和血清UA、PGE2水平。术后3 d内对所有患者进行谵妄量表(CAM-S)评分,根据评分结果分为谵妄组(27例)和非谵妄组(93例)。采用Spearman分析评估NLR、UA、PGE2与美国麻醉医师协会(ASA)分级的相关性。采用多因素Logistic回归分析评估老年髋部骨折患者术后谵妄的影响因素。采用受试者工作特征(ROC)曲线评价NLR、UA、PGE2判断老年髋部骨折患者术后谵妄的效能。结果 谵妄组ASA分级Ⅲ~Ⅳ级所占比例、NLR和血清UA、PGE2水平均显著高于非谵妄组(P<0.05)。NLR、UA、PGE2均与ASA分级呈正相关(rs值分别为0.447、0.424、0.487,P<0.001)。NLR、UA、PGE2升高均是老年髋部骨折患者术后谵妄的危险因素(P<0.05)。NLR、UA、PGE2单项检测和联合检测判断老年髋部骨折患者术后谵妄的曲线下面积分别为0.834、0.823、0.861、0.968。结论 术前NLR和血清UA、PGE2水平升高是老年髋部骨折患者术后谵妄的危险因素,NLR、UA、PGE2联合检测可提高对老年髋部骨折患者术后谵妄的预测效能。

Abstract:

Objective To investigate the predictive value of preoperative neutrophil-to-lymphocyte ratio(NLR),uric acid(UA)and prostaglandin E2(PGE2) combined determination for postoperative delirium in elderly patients with hip fractures. Methods A total of 120 elderly patients with hip fractures who underwent surgical treatment at Shijiazhuang Third Hospital from April to December 2023 were enrolled. The clinical data were collected,and preoperative NLR and serum UA and PGE2 levels were determined. Within 3 d after surgery,all the patients were scored using the confusion assessment method-severity(CAM-S) delirium scale,and they were classified into delirium group(27 cases) and non-delirium group(93 cases). Spearman analysis was used to evaluate the correlation between NLR,UA,PGE2 and American Society of Anesthesiologists(ASA) grades. Multivariate Logistic regression analysis was used to evaluate the influencing factors of postoperative delirium in elderly patients with hip fractures. The efficacy of NLR,UA and PGE2 in judging postoperative delirium in elderly patients with hip fractures was evaluated using receiver operating characteristic(ROC) curve. Results The proportion of ASA grade Ⅲ-Ⅳ,NLR and serum UA and PGE2 levels in delirium group were higher than those in non-delirium group(P<0.05). NLR,UA and PGE2 were positively correlated with ASA grades(rs values were 0.447,0.424 and 0.487,respectively,P<0.001). Elevated NLR,UA and PGE2 were all risk factors for postoperative delirium in elderly patients with hip fractures(P<0.05). The areas under curves for single and combined determinations of NLR,UA and PGE2 in judging postoperative delirium in elderly patients with hip fractures were 0.834,0.823,0.861 and 0.968,respectively. Conclusions Elevated preoperative NLR and serum UA and PGE2 levels are risk factors for postoperative delirium in elderly patients with hip fractures. The combined determination of NLR,UA and PGE2 can improve the predictive efficacy of postoperative delirium in elderly patients with hip fractures.
