Abstract

Abstract : Elderly patients with various comorbidities are more likely to suffer from proximal femur fractures. It is also a painful fracture, and poor pain management can have serious physiological and psychological consequences, such as acute delirium. Purpose . The aim of this study is to compare the efficacy of ultrasound-guided transmuscular (anterior) quadratus lumborum block (QLB) versus infrainguinal fascia iliaca compartment block (FICB) in proximal femur fractures for postoperative analgesia. Patient-reported pain on the visual analogue scale (VAS), analgesic demand, and ambulation were the key factors. Patients and Methods . This prospective, randomised trial was done after receiving approval from the institute' study ethical committee. In this study, ultrasound-guided infrainguinal fascia iliaca compartment block was compared to ultrasound-guided anterior quadratus lumborum block using 50 ml of bupivacaine 0.25%, with a maximum dose of 2.5 mg/kg at the end of surgery after spinal anaesthesia in 128 patients (64 patients in each group). Nalbuphine was given as rescue analgesia if VAS >3. Our 1 st outcome was the first rescue analgesia and total analgesic consumption in the 1 st 24 hours; the 2 nd outcome was the time patients started to ambulate. Results . Postoperative pain perception was substantially greater in the FICB group starting from 30 min ( P value 0.022) till 24 hours (P value <0.001), and they received a considerably larger total narcotic dose (14.1 ± 3.5) than patients in the QLB group (7.9 ± 3.4), P value (<0.001 ∗ ). The time required to achieve first rescue analgesia was much less in the FICB group (8.5 ± 2.2) compared to the QLB group (14.1 ± 4.5), P value (<0.001 ∗ ), and they took much longer to ambulate (22.3 ± 4.8) when compared to the QLB group (20.1 ± 4.6), P value (0.011 ∗ ). Hypotension (1.6%) was detected mainly in the QLB group, whereas poor fascial separation (1.6%) was observed only in the FICB group. There were no significant differences in complications between both the FICB and QLB groups. Conclusion . Patients receiving postoperative anterior QL block for proximal femur fracture demonstrated delayed first rescue analgesia and lower total nalbuphine consumption with early ambulation than patients who received FICB.
