Upper Extremity Position and Intraocular Pressure During Spinal Anesthesia: A Randomized Controlled Trial
Sponsor: Elazıg Fethi Sekin Sehir Hastanesi
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 after application of the assigned upper extremity position between the two upper extremity position groups.

Interventions
Upper Extremity Positioning
Participants were assigned to one of two upper extremity positions after the T15 intraocular pressure measurement: arms positioned alongside the body or hands positioned over the chest. The assigned position was maintained for approximately 30 minutes until the final T45 intraocular pressure measurement.
