UNLABELLED Research suggests that the addition of dexmedetomidine to local anesthetics can prolong peripheral nerve blocks; however, it is not known whether dexmedetomidine can reduce the quantity of local anesthetic needed. We hypothesized that adding dexmedetomidine as an adjuvant to an obturator nerve block could reduce the median effective concentration of lidocaine. In this double-blinded ...
BACKGROUND Optimal analgesia for total knee arthroplasty remains challenging. Many modalities have been used, including peripheral nerve block, periarticular infiltration, and epidural analgesia. However, the relative efficacy of various modalities remains unknown. The authors aimed to quantify and rank order the efficacy of available analgesic modalities for various clinically important outcom...
all surgical positions carry some degree of position-related risks. the most common serious positional injuries are peripheral nerve injuries. we present a case of 23 years old man with obturator nerve injury with clinically evident sequelae following a scapulopexy of the right shoulder in prone position. basis on our knowledge, no similar cases have been described in the literature. the purpos...
This review outlines the anatomy of the obturator nerve and the indications for obturator nerve block (ONB). Ultrasound-guided ONB techniques and unresolved issues regarding these procedures are also discussed. An ONB is performed to prevent thigh adductor jerk during transurethral resection of bladder tumor, provide analgesia for knee surgery, treat hip pain, and improve persistent hip adducto...
BACKGROUND AND OBJECTIVES This study was conducted to provide a thorough description of the variability in the obturator nerve branching pattern in the inguinal region. METHODS The anatomic variability of obturator nerve branching among 84 dissected embalmed cadavers was investigated. Ultrasound examination of the inguinal region was undertaken in 20 cases and the location of the obturator ne...
BACKGROUND Obturator nerve (ON) stimulation during transurethral resection of lateral and posterolateral bladder wall tumor under spinal anesthesia may lead to obturator reflex, adductor contraction, and leg jerking with complications such as bleeding, bladder perforation, or incomplete tumor resection. Our study was carried out to obtain successful block of ON using ultrasound (US)-guided tech...
Effect of FK506 administration after obturator nerve injury: a functional and ultrastructural study.
The frequency of obturator nerve damage due to pelvic diseases, fractures or gynecologic procedures is uncertain. In the present study, we investigated the effect of FK506, a potent macrolide antibiotic and immunosuppresant, on obturator nerve recovery at morphological and functional levels. Forty female Wistar rats were randomly divided into four groups (control, sham, FK506-treated, vehicle-t...
Single spinal anesthesia in transurethral resection of bladder tumor (TURBT) has been reported to be unable to prevent obturator nerve stimulation and adductor muscle contraction, which can cause complications like bladder perforation. The present study aimed to compare the effectiveness of the classic and inguinal approaches for obturator nerve block (ONB). Seventy patients with cancers of the...
