U.S., Nov. 14 -- ClinicalTrials.gov registry received information related to the study (NCT07936435) titled 'SPENG Block Versus Superior Trunk Block for Shoulder Surgery: Effects on Diaphragmatic Function, Mechanical Power, Nociception, and Analgesia: A Randomized Controlled Trial' on Nov. 07.
Brief Summary: Shoulder and upper extremity surgery causes severe postoperative pain. The interscalene brachial plexus block is the standard regional analgesia technique, but it causes ipsilateral hemidiaphragmatic paralysis (HDP) in almost all patients because of its proximity to the phrenic nerve.
