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

In our prospective randomized study, 130 patients underwent a transurethral resection (TUR) because a neoplasm was located on the side wall of the bladder. In the neurostimulation (NS) group (n = 50), a spinal anesthesia with an obturator nerve block was made under the control of a neurostimulation; in the ultrasound (US) + NS group (n = 50), a spinal anesthesia with an obturator nerve block was made under the double control of ultrasound navigation and neurostimulation; in the general anesthesia (GA) group (n = 30), a general anesthesia with a deep myoplegia was made. Results: The obturator nerve reflex was recorded for three (6%) patients from the NS group (p 0.001); it caused a bladder perforation in one patient. The frequency of a sinus bradycardia in the NS (18%) and US + NS (20%) groups was lower than in the GA (43%) group, p = 0.008. Arterial hypotension was observed only in the OA group for 8 (27%) patients (p 0.001). In the NS and US + NS groups, the patients time in the surgery room was significantly less (p 0.001) than in the OA group averaging 48.36 17.58 min and 50.82 23.6 min, respectively. Conclusion: The combination of a spinal anesthesia with obturator nerve block under the dual control of an ultrasound navigation and a neurostimulation can be considered as a reliable and safe method of an anesthetic maintenance of the TUR on the wall of the bladder. If it is impossible to provide such a control over the implementation of the blockade, it is necessary to resort to a GA with a deep myoplegia.

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.

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.

Abstract Objective: The meta-analysis aims to identify whether out of hospital cardiac arrest (OHCA) survivors of non ST-segment elevation (NSTE) can benefit from early coronary angiography (CAG) and percutaneous coronary intervention (PCI).Methods: The relevant studies from MEDLINE, Cochrane Library, Embase were searched by two independent investigators using a variety of keywords. Stata software (version 12.0, Stata Corp LP, College Station, TX, USA) was used for statistical analysis. Results: A total of 12 studies (9 observational studies, 1 cohort study and 2 randomized control trials) were identified and incorporated into the meta-analysis. For overall analysis, the strategy of early angiography was associated with decreased short-term (hospital discharged) mortality (RR=0.72, 95% CI=0.56-0.93, P=0.000) and long-term (follow up) mortality (RR=0.84, 95% CI=0.71-0.99, P=0.007). However, when analyzed in the subgroup of randomized controlled study, the strategy of early angiography didn’t have survival benefit in the randomized controlled study group for short-term mortality (RR=1.12, 95% CI=0.89-1.41, P=0.331) and long-term mortality (RR=1.06, 95% CI=0.85-1.32, P=0.572). Meanwhile, our analysis found that, if early CAG performed, PCI followed by CAG is not associated with hospital discharged mortality (RR=1.14, 95% CI=0.96-1.37, P=0.132) compared with CAG alone. No significant differences between the groups were found in the remaining secondary endpoints.Conclusion: Due to the observational nature of the studies available, we may consider that early CAG and PCI is not be recommended for patients with NSTE OHCA.
