Poloha horní končetiny a nitrooční tlak během spinální anestezie (UEP-IOP)
Vliv polohy horní končetiny na nitrooční tlak během spinální anestezie při otevřené operaci tříselné kýly: randomizovaná kontrolovaná studie
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.

Detailní popis
Intraocular pressure (IOP) may be influenced by systemic hemodynamics, venous return, episcleral venous pressure, and patient positioning. Although the effects of head and body position on IOP have been investigated, the impact of upper extremity positioning during spinal anesthesia has not been clearly established. This prospective randomized controlled trial was conducted at Elazig Fethi Sekin City Hospital. Adult patients scheduled for elective surgery under spinal anesthesia were enrolled. After written informed consent, participants were randomly assigned to one of two upper extremity positions: arms positioned alongside the body or hands positioned on the chest. IOP was measured in the right eye using an Icare ic200 rebound tonometer. Measurements were obtained at baseline before spinal anesthesia, 15 minutes after spinal anesthesia immediately before application of the assigned upper extremity position, and 30 minutes after application of the assigned position (approximately 45 minutes after spinal anesthesia). Head and neck position was maintained neutral throughout the measurement period. Hemodynamic parameters, including mean arterial pressure, heart rate, and peripheral oxygen saturation, were recorded simultaneously. The primary outcome was the between-group comparison of the change in IOP from baseline to 30 minutes after application of the assigned upper extremity position. Secondary outcomes included IOP change at 15 minutes and perioperative hemodynamic changes.

Experimentální: Arms-at-Sides Position
Participants underwent spinal anesthesia. After the T15 intraocular pressure measurement, both arms were positioned alongside the body, parallel to the torso, with the palms facing upward, and this position was maintained for approximately 30 minutes until the final T45 measurement. |
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. |
|
Experimentální: Hands-on-Chest Position
Participants underwent spinal anesthesia. After the T15 intraocular pressure measurement, both upper extremities were adducted with the elbows flexed, and the open hands were placed one over the other on the anterior chest wall. This position was maintained for approximately 30 minutes until the final T45 measurement. |
