Peri-acetabular osteotomy is the joint-preserving treatment of choice in young adults with hip dysplasia but is associated with intense pain and high opioid consumption postoperatively.
To investigate whether 48 mg of pre-operative dexamethasone was superior to a standard dose of 8 mg on reducing pain in the immediate postoperative phase.
A randomised, double-blind trial.
Single-centre, primary facility. May 2017 to August 2019.
At least 18 years undergoing peri-acetabular osteotomy.
Patients were randomised 1 : 1 to 48 or 8 mg dexamethasone intravenous (i.v.) as a single pre-operative injection. All patients received a standardised peri-operative protocol, including pre-operative acetaminophen and gabapentin, total i.v. anaesthesia and local anaesthetic catheter based wound administration.
Number of patients with moderate/severe pain [>3 on a numeric rating scale (NRS)] in the immediate postoperative phase.
Sixty-four patients (32 in each group) were included, and their data analysed. At some point from tracheal extubation until transfer to the ward, the NRS was more than 3 in 75% (24/32) of the 48 mg group and in 66% (21/32) in the 8 mg group, odds ratio 1.571 (95% CI, 0.552 to 4.64), P = 0.585. Patients in the 48 mg group received less opioid [cumulative rescue analgesics, oral morphine equivalents (OMEQ)] during postoperative days 0-4: median [IQR] OMEQ was 36 [15 to 85] mg vs. 79 [36 to 154] mg in the 48 and 8 mg group, respectively, P = 0.034. There were no statistically significant differences regarding complications, rate of infections or readmissions.
Forty-eight milligram of dexamethasone did not reduce pain in the immediate postoperative phase compared with an 8 mg dose. We observed insignificantly lower pain scores and significantly lower cumulated opioid requirements in the 48 mg group during the first four postoperative days.

髋臼周围截骨术是年轻髋关节发育不良患者首选的保关节治疗方法，但术后疼痛剧烈，阿片类药物消耗量大。
研究术前使用 48mg 地塞米松是否优于标准剂量 8mg 地塞米松，以减少术后即刻的疼痛。
随机、双盲试验。
单中心，初级医疗机构。2017 年 5 月至 2019 年 8 月。
至少 18 岁，行髋臼周围截骨术。
患者按 1：1 随机分为 48mg 或 8mg 地塞米松静脉（i.v.）单次术前注射组。所有患者均接受标准化围手术期方案，包括术前对乙酰氨基酚和加巴喷丁、全静脉麻醉和局部麻醉导管伤口给药。
术后即刻有中度/重度疼痛（NRS>3）的患者人数。
共纳入 64 例患者（每组 32 例），并对其数据进行了分析。在气管拔管至转至病房的某个时间点，48mg 组中 75%（24/32）的患者和 8mg 组中 66%（21/32）的患者的 NRS 评分大于 3，比值比为 1.571（95%CI，0.552 至 4.64），P=0.585。48mg 组患者在术后第 0-4 天接受的阿片类药物（口服吗啡等效剂量（OMEQ））更少：中位数[IQR]OMEQ 分别为 36[15 至 85]mg 和 79[36 至 154]mg，48mg 和 8mg 组，P=0.034。两组在并发症、感染率或再入院率方面无统计学差异。
与 8mg 剂量相比，48mg 地塞米松并未减轻术后即刻的疼痛。我们观察到在术后第 1-4 天，48mg 组的疼痛评分和累积阿片类药物需求显著降低。
