Effects of Different Types of Anaesthesia on Intraocular Pressure During Lumbar Disc Herniation Surgery

Effects of Propofol, Desflurane and Spinal Anesthesia on Intraocular Pressure During Lumbar Disc Herniation Surgery: A Randomized Controlled Study

The aim of this study was to investigate the effects of anaesthesia methods on intraocular pressure during lumbar disc surgery performed in the prone position.

The study included 75 patients with lumbar disc herniation between the ages of 18-75, with the American Society of Anesthesiologists (ASA) 1-2. The patients were randomly divided into 3 groups: propofol, desflurane, spinal. Intraocular pressure (IOP) was measured at 5 time points throughout surgery, including baseline (T1), 10 minutes after anesthesia (T2), 10 minutes after prone positioning (T3: early prone), 30 minutes after prone positioning (T4: late prone), and 10 minutes after returning to the supine position (T5). Hemodynamic parameters were measured at these time points. Hemoglobin and hematocrit values were measured preoperatively and on the first postoperative day.

Inclusion Criteria:

• ASA 1-2 according to the American Society of Anesthesiologists (ASA) Classification.

Exclusion Criteria:

• Who did not sign the informed consent form,
• patients who required emergency surgery,
• eye surgery recipients,
• subjects with acute or chronic eye diseases other than refractive errors,
• individuals detected to have elevated IOP in preoperative measurements
