PURPOSE: Postoperative delirium (POD) is considered the most common postoperative neurological complication in elderly patients. The aim of this study was to evaluate the efficacy of the administration of ketofol versus dexmedetomidine (DEX) for minimizing POD in elderly patients undergoing urgent exploration for intestinal obstruction. METHODS: This prospective double-blinded randomized clinical trial was conducted on 120 elderly patients undergoing urgent exploration for intestinal obstruction. Patients were randomly allocated to one of the three groups: Group C (control group) patients received normal saline 0.9%, group D received dexmedetomidine, and group K received ketofol (ketamine: propofol was 1:4). The primary outcome was the incidence of POD. Secondary outcomes were incidence of emergence agitation, postoperative pain, consumption of rescue opioids, hemodynamics, and any side effects. RESULTS: The incidence of POD was statistically significantly lower in ketofol and DEX groups than in the control group at all postoperative time recordings. Additionally, VAS scores were statistically significantly decreased in the ketofol and DEX groups compared to the control group at all time recordings except at 48 and 72 h postoperatively, where the values of the three studied groups were comparable. The occurrence of emergence agitation and high-dose opioid consumption postoperatively were found to be significant predictors for the occurrence of POD at 2 h and on the evening of the 1st postoperative day. CONCLUSION: The administration of ketofol provides a promising alternative option that is as effective as DEX in reducing the incidence of POD in elderly patients undergoing urgent exploration for intestinal obstruction. TRIAL REGISTRATION: This clinical trial was approved by the Institutional Review Board (IRB) at Zagazig University (ZU-IRB# 6704// 3/03/2021) and ClinicalTrials.gov (NCT04816162, registration date 22/03/ 2021). The first research participant was enrolled on 25/03/2021).
目的:术后谵妄(POD)被认为是老年患者中最常见的术后神经系统并发症。本研究旨在评估酮咯酸与右美托咪定(DEX)用于最小化接受紧急肠梗阻探查的老年患者 POD 的疗效。
方法:本前瞻性双盲随机临床试验纳入了 120 名接受紧急肠梗阻探查的老年患者。患者随机分配至三组:C 组(对照组)患者接受生理盐水 0.9%,D 组接受右美托咪定,K 组接受酮咯酸(氯胺酮:丙泊酚为 1:4)。主要结局为 POD 发生率。次要结局为苏醒期躁动、术后疼痛、阿片类药物补救用量、血流动力学和任何不良反应的发生率。
结果:在所有术后时间点,酮咯酸和 DEX 组的 POD 发生率明显低于对照组。此外,与对照组相比,酮咯酸和 DEX 组在所有时间点的 VAS 评分均显著降低,除术后 48 和 72 小时,三组的数值相当。术后苏醒期躁动和大剂量阿片类药物的使用被发现是 2 小时和术后第 1 天晚上 POD 发生的显著预测因素。
结论:酮咯酸的给药提供了一种有前途的替代方案,与 DEX 一样有效,可降低接受紧急肠梗阻探查的老年患者 POD 的发生率。
试验注册:本临床试验获得了 Zagazig 大学机构审查委员会(IRB)(ZU-IRB#6704//3/03/2021)和 ClinicalTrials.gov(NCT04816162,注册日期 2021 年 3 月 22 日)的批准。第一位研究参与者于 2021 年 3 月 25 日入组。
