Upper Extremity Position and Intraocular Pressure During Spinal Anesthesia: A Randomized Controlled Trial

Study acronym: UEP-IOP
Completed
View on ClinicalTrials.gov →
Summary
This prospective randomized controlled trial evaluated the effect of two upper extremity positions on intraocular pressure (IOP) in adult patients undergoing surgery under spinal anesthesia. Participants were randomly assigned to either an arms-at-sides position or a hands-on-chest position. IOP was measured in the right eye using an Icare ic200 rebound tonometer at predefined perioperative time points. Hemodynamic parameters, including mean arterial pressure, heart rate, and oxygen saturation, were also recorded. The primary outcome was the change in IOP from baseline to 30 minutes between the two upper extremity position groups.
