Clinical Trial: Effects of Injection Volume and Site on Sensory Distribution After Rectus Sheath Block

U.S., Oct. 16 -- ClinicalTrials.gov registry received information related to the study (NCT07876297) titled 'Effects of Injection Volume and Site on Sensory Distribution After Rectus Sheath Block' on Oct. 09.

Brief Summary: This randomized controlled study aims to evaluate the effects of local anesthetic injection volume and injection site on cutaneous sensory distribution following ultrasound-guided rectus sheath block (RSB). Participants undergoing laparoscopic abdominal surgery will be randomized to receive RSB using different injection sites and volumes (20 mL or 30 mL per side). Injection sites will be selected according to the surgical location, including upper, middle, or lower rectus sheath approaches. Cutaneous sensory distributio...
