Ultrasound-guided obturator nerve block technique at the distal end of the obturator canal: case series and cadaver evaluation.
The obturator nerve variably gives off the anterior, posterior, and hip articular branches along its course; however, all branches invariably pass through the obturator canal. Herein, we describe our obturator nerve block technique, which promises to deliver local anesthetic directly into the obturator canal. We performed the obturator nerve block in six patients undergoing transurethral resection of bladder tumor under spinal anesthesia. ⋯ The procedure was repeated using 10-ml dye in a cadaver. No obturator jerks were observed during the transurethral resection of bladder tumors in all six cases. Cadaver examination confirmed the dye stained the obturator nerve, with retrograde spread into the pelvic cavity via the obturator canal.

Randomized Controlled TrialA novel stimulating electrode attachment method designed to maintain electromyography-based neuromuscular monitoring detectability during laparoscopic surgery: a single-center randomized, double-blind, controlled pilot study.
We evaluated the electromyography (EMG)-based neuromuscular monitoring detectability of our novel stimulating electrode attachment method compared to the original Nihon-Kohden (Tokyo, Japan) attachment method. ⋯ Crossing the line connecting the anode and cathode with the ulnar nerve stabilizes EMG-based neuromuscular monitoring detectability.

Randomized Controlled Trial Comparative StudyComparing the hemodynamic effects of ketamine versus fentanyl bolus in patients with septic shock: a randomized controlled trial.
Ketamine and fentanyl are commonly used for sedation and induction of anesthesia in critically ill patients. This study aimed to compare the hemodynamic effects of ketamine versus fentanyl bolus in patients with septic shock. ⋯ gov Identifier: NCT05957302. URL: https://clinicaltrials.gov/study/NCT05957302 .
