U.S., June 3 -- ClinicalTrials.gov registry received information related to the study (NCT07620002) titled 'Nociception Level Index After Brachial Plexus Block In Upper Extremity Surgery' on May 10.
Brief Summary: The present prospective within-subject observational study will evaluate whether unilateral brachial plexus block (BPB) induces measurable lateralized autonomic modulation, assesses using bilateral Nociception Level (NoL) monitoring during standardized intraoperative stimuli under general anesthesia. Regional anesthesia efficacy is traditionally assessed through sensory and motor examination. However, objective physiologic markers reflecting sympathetic modulation remain limited. Forty five adults undergoing upper extremity surge...
