A randomized, controlled simulation study comparing single and double operator ultrasound-guided regional nerve block techniques using a gelatine-based home-made phantom.

Background: The aim of this study was to compare anesthesiology residents' acquisition of gripping and needling skills in either single-or double-operator ultrasound-guided nerve block using a hand-made phantom.

Design: Prospective, randomized controlled study.

Methods: After a tutorial session, 47 ultrasound-novice residents performed needling with double and single operator (Jedi, Bedforth, On-lock) grip techniques in each of the 3 interventional task sessions.

Should the Erector Spinae Plane Block Be Applied in the Pain Management of Percutaneous Nephrolithotomy?

Introduction This prospective, randomized controlled study aimed to investigate the efficacy and respiratory effects of postoperative pain management with an erector spinae plane block in patients undergoing percutaneous nephrolithotomy. Methods Sixty American Society of Anesthesiologists (ASA) I-II patients aged 18-65 years, scheduled to undergo percutaneous nephrolithotomy, were randomized either to the erector spinae plane block (ESPB) or control group.
