-
摘要:
目的 探究老年患者股骨头坏死全髋置换术后谵妄综合征及其影响因素,为临床制定针对性预防干预措施提供理论参考。 方法 选择2020年1月—2022年5月于温州医科大学附属第二医院骨科行全髋置换术治疗的194例老年股骨头坏死患者为观察对象,通过自制调查量表采集患者临床资料,并经意识模糊评估量表(CAM)调查患者是否发生谵妄综合征,调查谵妄综合征发生率,采用多因素logistic回归法分析老年患者股骨头坏死全髋置换术后并发谵妄综合征的影响因素。 结果 194例老年股骨头坏死患者全髋置换术后发生谵妄综合征者有26例,发生率为13.40%;有谵妄综合征组、无谵妄综合征组患者在年龄、肺部疾病、夜间睡眠障碍、营养障碍、麻醉方式、手术操作时间、术中机体出血量、术后机体VAS评分、术后血清CRP水平、术后低氧血症发生率方面对比,差异均有统计学意义(均P<0.05);多因素logistic分析显示,高龄、肺部疾病、夜间睡眠障碍、营养障碍、麻醉方式(全麻)、手术操作时间长、术中机体出血量多、术后机体VAS评分≥7分、术后血清CRP水平增高、术后低氧血症是老年股骨头坏死患者全髋置换术后谵妄综合征发生的影响因素(均P<0.05)。 结论 老年股骨头坏死患者受年龄、肺部疾病、睡眠障碍、机体营养水平等因素影响,全髋置换术后存在较高的谵妄风险,临床应提供针对性预防干预,以降低患者术后并发谵妄综合征的风险。 Abstract:Objective To explore the delirium syndrome after total hip replacement in elderly patients with femoral head necrosis and its influencing factors, and to provide theoretical reference for clinical development of targeted preventive interventions. Methods A total of 194 cases of elderly patients with femoral head necrosis who underwent total hip replacement in the Department of Orthopedics, the Second Affiliated Hospital of Wenzhou Medical University from January 2020 to May 2022 were selected as the observation subjects. The clinical data of patients were collected by self-made survey scale, and the occurrence of delirium syndrome was investigated by the Fuzzy consciousness assessment method (CAM) and the incidence of delirium syndrome was investigated. Multivariate logistic regression was used to analyze the influencing factors of delirium syndrome after total hip replacement in elderly patients with femoral head necrosis. Results There were 26 cases of delirium syndrome after total hip replacement in 194 elderly patients with femoral head necrosis, the incidence was 13.40%. There were differences in age, pulmonary disease, nocturnal sleep disorder, nutritional disorder, anesthesia method, operation time, intraoperative blood loss, postoperative VAS score, postoperative serum CRP level, and postoperative hypoxemia incidence between patients with and without delirium syndrome (all P < 0.05). Multivariate logistic analysis found that advanced age, pulmonary diseases, nocturnal sleep disorders, nutritional disorders, anesthesia method (general anesthesia), long operation time, large amount of intraoperative blood loss, postoperative VAS score ≥7, postoperative serum CRP level increased, and postoperative hypoxemia were the influencing factors for the occurrence of delirium syndrome after total hip replacement in elderly patients with femoral head necrosis (all P < 0.05). Conclusion Elderly patients with femoral head necrosis are affected by age, lung disease, sleep disorder, nutritional level and other factors, and there is a high risk of delirium after total hip replacement. Clinical preventive interventions should be provided to reduce the risk of postoperative delirium syndrome. -
