J Urol 1980;123:170-2. Complications resulting from poor nerve blockade and subsequent adductor jerks have been reported in many studies. 2000;164:152932. The functionality is limited to basic scrolling. Capibaribe DM, Dal Col LSB, Jalalizadeh M, Reis LO. However, ONB in TURBT can prevent obturator reflex to avoid complications such as bleeding, bladder perforation, or incomplete tumor resection.[7,8,9,10,11]. [17,18,19,20] Different approaches for the ONB have evolved in the last decade. Early complications of endoscopic treatment for superficial bladder tumors.

A literature search was performed on PubMed using the following search criteria "obturator nerve block", "obturator nerve block in transurethral resection of bladder tumor", "adductor spasm during transurethral resection of bladder tumor", "bi-polar diathermy obturator nerve", and "transvesical obturator nerve block". [16] Stimulation of the ON by electric current during TURBT causes sudden jerk (obturator reflex) due to contraction of adductor muscles. 6 resection of bladder tumors at the lateral bladder wall stimulates the obturator nerve and results in adductor muscle contraction, a phenomenon known as the obturator nerve reflex. Subjects and Methods: Forty adult male patients from the American Society of Anesthesiologists Class IIV planned to undergo TURBT under spinal anesthesia were divided into two groups of twenty each. We conclude that both techniques are safe and easy to perform; however, nerve stimulation as an adjunct to US results in a faster onset of block with a higher success rate.

Adductor spasm; Obturator jerk; Obturator reflex; Transurethral resection of bladder tumor. Peripheral nerve blocks remain a well-accepted component of comprehensive anesthetic care. A number of transfusions required and bladder perforation were the secondary endpoints. obturator nerve block (onb) is commonly performed to prevent sudden thigh adduction during transurethral resection of bladder tumor (turbt) [1-3], to provide optimal analgesia for knee surgery [4-6], to treat chronic hip pain [7-9], and to improve persistent hip adductor spasticity in patients with paraplegia, multiple sclerosis, or cerebral 104.

A Systematic Review and Meta-Analysis Comparing the Safety and Efficacy of Spinal Anesthesia and Spinal Anesthesia Combined with Obturator Nerve Block in Transurethral Resection of Bladder Tumors. The ON is one such nerve that can be both, difficult to stimulate electrically and image sonographically. Avoiding overfilling of the bladder during TURBT reduces the risk of obturator nerve stimulation, as a distended bladder brings the lateral bladder wall closer to the obturator nerve. Regional anesthesia is another potential treatment modality to prevent the obturator reflex during TURBT. Saudi J Anaesth 2011;5:42-4. If muscle contractions were still observed in both the medial aspect of thigh and the sonogram, 5 ml of 0.5% bupivacaine was injected. Anatomy The obturator nerve is a mixed nerve, which, in most cases, provides motor function to the adductor muscles and cutaneous sensation to a small area behind the knee.

Five minutes after the end of injection, the surgeon who was masked to group assignment entered the operating room to start TURBT and evaluate the motor blockade, which was graded as follows: The strength of thigh adduction was measured at 5, 10, 15 min (min) after injection, and a score of 2 was considered as a successful block. Abstract Introduction: The aim of the study was to evaluate the effectiveness of a modified transvesical obturator nerve block (ONB) in the prevention of obturator nerve reflex and consecutive bladder perforations (BPs) during transurethral resection of bladder tumors (TURBTs).
