Obturator nerve block during transurethral bladder resection

Background: Unwanted high-frequency electrostimulation of obturator nerve provokes very often a leg movement and can be dangerous during transurethral surgery. The goal of study was: can we provide better and safer condition for surgeon work without additional complications? Methods: 60 patients with bladder tumor of lateral wall were divided in two groups: First group (20 men and 10 women) have received only spinal anesthesia (3ml of Bupivacain 0.5%, needle G 25, L1-L2 space) and Second group (19 men and 11 women) have received spinal anesthesia and n. obturator blockade (20 ml of Bupivacain 0.25% Labatsu technique). Results: We have noticed 8 times more n. obturator stimulation and consequent leg movements in first group (26.67%) than in group two (3.33%) and this difference is statistically significant (p<0.05). Average electro stimulation for nerve identification was 2.35 Ma. We did not notice any complication. Conclusion: This is very cheep, short and simply, technique which provide better and safer condition for surgeon work during transurethral resection and we like to emphasize and add this indications as a new and beneficial. .
