Fascia iliaca nerve blockade (FIB) has been previously described as an effective technique for reducing postoperative pain and opioid consumption after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). We hypothesize that an FIB will significantly reduce opioid consumption, pain scores and recovery time in our population. A retrospective observational study of 326 consecutive patients undergoing hip arthroscopy for FAIS at a single institution was performed. Patients were classified based on whether or not they received an FIB. Patient demographics, surgical details, medication details and 6-month postoperative outcomes were collected. The primary endpoint was the amount of narcotics required intraoperatively and in the postanesthesia care unit (PACU). Of the 326 patients included in the study, 37 received an FIB. No differences in sex, age or other surgical details were observed between groups. Patients receiving an FIB were more likely to receive celecoxib (P < 0.001), pregabalin (P = 0.001) and methocarbamol (P = 0.002). The FIB group received lower doses of narcotics intraoperatively (P = 0.001), postoperatively (P < 0.001) and in total (P < 0.001). The FIB group also self-reported lower first pain scores upon arrival to PACU (P = 0.001) and experienced shorter PACU recovery times (P < 0.001). After controlling for differences between groups, patients who received an FIB required significantly lower amounts of narcotics, had shorter PACU times and lower first PACU pain score than those who did not (P < 0.001). No differences in complication rates were noted between groups. The use of FIB resulted in lower pain scores, reduced recovery time and decreased early postoperative narcotic requirements for patients undergoing hip arthroscopy for femoroacetabular impingement. Further study is required to validate these findings and determine the optimal approach to regional analgesia in this patient population.

髂筋膜神经阻滞对股髋臼撞击综合征髋关节镜术后早期疼痛及恢复的影响

髂筋膜神经阻滞 (FIB) 先前已被描述为一种有效的技术，可用于减少股骨髋臼撞击综合征 (FAIS) 髋关节镜检查后术后疼痛和阿片类药物的消耗。我们假设 FIB 将显着减少我们人群的阿片类药物消耗、疼痛评分和恢复时间。对 326 名在单一机构接受髋关节镜检查 FAIS 的连续患者进行了回顾性观察研究。根据患者是否接受 FIB 对患者进行分类。收集了患者的人口统计资料、手术细节、用药细节和术后 6 个月的结果。主要终点是术中和麻醉后护理室 (PACU) 所需的麻醉剂数量。在纳入研究的 326 名患者中，37 名接受了 FIB。两组之间没有观察到性别、年龄或其他手术细节的差异。接受 FIB 的患者更有可能接受塞来昔布 (P < 0.001)、普瑞巴林 (P = 0.001) 和美索巴莫 (P = 0.002)。FIB 组在术中 (P = 0.001)、术后 (P < 0.001) 和总体 (P < 0.001) 接受较低剂量的麻醉剂。FIB 组在到达 PACU 时也自我报告了较低的首次疼痛评分 (P = 0.001)，并且经历了较短的 PACU 恢复时间 (P < 0.001)。在控制组间差异后，与未接受 FIB 的患者相比，接受 FIB 的患者需要的麻醉剂数量显着减少，PACU 时间更短，首次 PACU 疼痛评分更低（P < 0.001）。两组间并发症发生率没有差异。FIB 的使用导致疼痛评分降低，缩短了接受髋关节镜检查治疗股骨髋臼撞击的患者的恢复时间并减少了术后早期的麻醉需求。需要进一步的研究来验证这些发现并确定该患者群体中局部镇痛的最佳方法。
