One of the forgotten techniques of regional anesthesia is blockade of the obturator nerve, which was performed using anatomical landmarks and neurostimulation. In recent years, ultrasonic navigation methods have gained wide popularity when using regional blockades. The purpose of the review is to present the current understanding of the use of obturator nerve block in clinical practice. The review presents the anatomical features of the obturator nerve passage, surgical and therapeutic indications for the use of its blockade. The technique for performing obturator blockade using ultrasound navigation is described in detail. Blockade of the obturator nerve using ultrasound navigation can reduce the likelihood of surgical complications during transurethral resection of a tumor located on the lateral wall of the bladder, improve analgesia after hip and knee surgery, and effectively relieve spastic conditions of the adductor muscles of the hip.

Background and objectivesA substantial group of patients suffer from moderate to severe pain following elective total hip arthroplasty (THA). Due to the complex innervation of the hip, peripheral nerve block techniques can be challenging and are not widely used. Since the obturator nerve innervates both the anteromedial part of the joint capsule as well as intra-articular nociceptors, we hypothesized that an obturator nerve block (ONB) would decrease the opioid consumption after THA.MethodsSixty-two patients were randomized to receive ONB or placebo (PCB) after primary THA in spinal anesthesia. Primary outcome measure was opioid consumption during the first 12 postoperative hours. Secondary outcome measures included postoperative pain score, nausea score and ability to ambulate.ResultsSixty patients were included in the analysis. Mean (SD) opioid consumption during the first 12 postoperative hours was 39.9 (22.3) mg peroral morphine equivalents (PME) in the ONB group and 40.5 (30.5) mg PME in the PCB group (p=0.93). No difference in level of pain or nausea was found between the groups. Paralysis of the hip adductor muscles in the ONB group reduced the control of the operated lower extremity compared with the PCB group (p=0.026). This did, however, not affect the subjects’ ability to ambulate.ConclusionsA significant reduction in postoperative opioid consumption was not found for active versus PCB ONB after THA.Trial registration numberNCT03064165 and 2017-000068-14.

Obturator Nerve Block

Introduction: In this prospective randomized controlled study, we investigated the efficacy of obturator nerve block (ONB) on adductor muscle spasm and related short-term outcomes and complications in patients who underwent transurethral resection of lateral wall-located bladder tumours (TURBT).Methods: Between July 2014 and February 2015, 70 patients scheduled to undergo TUR of lateral bladder wall tumours were enrolled in the study. All patients were preoperatively evaluated by cystoscopy and imaging tools and selected according to localized tumours on the lateral bladder wall. Patients were randomly allocated to Group SA (35 patients who underwent only spinal anesthesia) and Group ONB (35 patients who underwent spinal anesthesia combined with ONB by the nerve stimulator). An independent observer, blinded to the approach, evaluated the obturator signs, including adductor muscle contraction, bladder perforation, and completeness of the resection during the TURBT procedure.Results: The differences between groups regarding mean operation time, tumour size, and number were not statistically significant (p > 0.05). Adductor muscle contraction was detected in 40% of patients in Group SA and 11.4% in Group ONB. This difference was statistically significant (p = 0.021). Complete bladder perforation was detected in 2 patients in Group SA, whereas no perforation was observed in Group ONB. There was no case of severe bleeding in both groups. Conclusions: We found that ONB performed after spinal anesthesia was effective in preventing intraoperative complications due to adductor muscle spasm while performing TURBT. Our study limitations include its small sample size, since we only enrolled patients with primary lateral wall-localized bladder tumo

Objectives: To evaluate the efficacy of obturator nerve block combined with spinal anaesthesia for prevention of adductormuscle spasm and its associated complications during transurethral resection of bladder tumours located at its lateral and inferolateral wall.Study design: A prospective study. Setting: At AFIU Rawalpindi. Period: From January 2005 to December 2006. Material and methodFifty patients who had tumours at their lateral / inferolateral bladder wall of physical status ASA I - IV received spinal anaesthesia at 3r d or4l h lumbar space followed by obturator nerve block with a view to preventing adductor jerk during resection of tumour. Results: There wascomplete suppression of adductor jerk in 45 (90%) patients and surgery was completed smoothly. Two patients (4%) had mild adductorjerk and additional sedation was required. The block failed to work in 3 (6%) cases and required conversion to general anaesthesia. Thusthe procedure was successful in 94% (complete and partial suppression of jerk. Conclusion: We conclude that spinal anaesthesiacombined with obturator nerve block is an effective technique for preventing adductor jerk during TUR-BT, thus avoiding intra-operative andpost operative complication.
