Context: Fascia iliaca compartment block (FICB) is a useful modality to provide postoperative analgesia in patients with hip fracture undergoing surgery. Aims: The aims of this study were to compare the analgesic efficacy of suprainguinal versus infrainguinal approach of ultrasound-guided FICB using 0.2% ropivacaine in patients undergoing surgery for hip fracture under spinal anesthesia. Settings and Design: It was a prospective, randomized, controlled study. Subject and Methods: Group A (n = 25) received ultrasound-guided FICB by suprainguinal approach and Group B (n = 25) received ultrasound-guided FICB by infrainguinal approach. The primary objective was to compare 24-h postoperative analgesic efficacy using Numeric Rating Scale (NRS) score. Statistical Analysis: For data analysis, t-test, Mann–Whitney test, and Chi-square test were applied. Results: NRS score after 30 min of FICB in Group A was 2.36 ± 1.11 which was lower in comparison to 3.28 ± 0.94 in Group B (P = 0.002). NRS score during positioning in Group A was 2.16 ± 0.90, which was lower than Group B 3.08 ± 0.81 (P = 0. 0004). Greater block coverage was achieved in obturator nerve distribution in Group A 0.76 ± 0.52 compared to 0.16 ± 0.37 in Group B (P < 0.001). The total duration of analgesia was 493.40 ± 214.83 min, which was more in Group A than in Group B 367.48 ± 63.92 min (P = 0.007). Quality of recovery (QoR) score out of 150 in Group A was 120.60 ± 8.91 compared to 110.40 ± 7.59 in Group B (P < 0.001). Conclusion: FICB by suprainguinal approach provides better analgesia, sensory block coverage, and conditions for positioning for spinal anesthesia and also has a higher time to first rescue analgesic requirement with better QoR compared to infrainguinal approach.
