Effect of Position and Anesthetic Choice in Intraocular Pressure in Robotic GYN (Gynecologic) Oncology Patients
University of Florida
Summary
Steep Trendelenburg positioning and insufflation of the abdominal cavity have shown to increase intra ocular pressure. Different anesthetic techniques can alter intra ocular pressure and a small pilot study showed decrease in Intraocular Pressure (IOP) in robotic case in steep Trendelenburg with IV anesthetics (TIVA). We want to quantify the degree of change in Intraocular Pressure (IOP) in female patients undergoing robotic procedures for cancer. We want to detect the difference in increase of pressure with total IV anesthesia versus conventional balanced anesthesia
Description
During the day of surgery, the anesthesiologist trained by an ophthalmologist, will measure each eye's Intraocular Pressure (IOP) using a tonometer for both the Trendelenburg with IV anesthetics (TIVA) and propofol/fentanyl/rocuronium arms of the study. (The Tono-Pen XL Medtronic Solan, Jacksonville, FL) The Intraocular Pressure (IOP) for both eyes will be measured at seven time points: Time 1 induction after administration of sedative and local anesthesia in the eye. Both eyes of the patient will anesthetized using topical proparacaine hydrochloride ophthalmic solution 0.5%. Time 2 Post ind…
