Clinical Trial: Pupillary Light Reflex to Predict Post-Spinal Hypotension in Elective Cesarean Delivery

U.S., July 2 -- ClinicalTrials.gov registry received information related to the study (NCT07678723) titled 'Pupillary Light Reflex to Predict Post-Spinal Hypotension in Elective Cesarean Delivery' on June 25.

Brief Summary: This prospective observational cohort study investigates whether pre-anesthetic pupillary light reflex (PLR) parameters can predict the risk of hypotension following spinal anesthesia in women undergoing elective cesarean section. Spinal anesthesia-induced hypotension is common, with reported incidence rates of 50-90%, and current predictors such as baseline blood pressure and BMI have limited accuracy. PLR, a sensitive marker of autonomic nervous system balance, may offer a simple, objective, and non-invasive tool for ...
