Obturator anesthesia under ultrasound-guided combined with spinal anesthesia for endoscopic removal of bladder tumor
Main Article Content
Abstract
Objective: Evaluation of the efficacy of spinal anesthesia in conjunction with obturator nerve anesthesia under ultrasound guidance for endoscopic removal of bladder tumor.
Subjects and method: Randomized clinical intervention and comparing research on 70 patients divided into two groups. Group 1 (35 patients): Spinal anesthesia with bupivacaine; Group 2 (35 patients): Spinal anesthesia with bupivacaine combined with obturator nerve anesthesia with lidocaine under ultrasound supervision.
Results: 100% of patients in both groups reached a good level of pain inhibition that required surgery (good levels were 85.7% and 91.4%, respectively); adductor myoclonus was less common in patients' group 2 than those in group 1 (62.9%) (p < 0.05).
Conclusion: Obturator nerve anesthesia under ultrasound guidance combined with spinal block for laparoscopic bladder tumor resection provides a good anesthetic effect to ensure surgery, and the rate of adductor muscle twitching is significantly lower than spinal anesthesia alone. The surgeon was satisfied with the anesthetic method applied.
