Effect of Position & Anesthetic Choice in Intraocular Pressure in Robotic

Status Recruiting

Clinical Trial 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

Clinical Trial 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 induction table 0 degrees Time 3 Supine after pneumoperitoneum with 14 mmHg pressure Time 4 After docking robot at correct Trendelenburg positioned measured by a level Time 5 After undocking and before moving supine Time 6 Supine and before extubation. If the intraocular pressure remains elevated above 19 mmHg will require a 7th measurement in PACU with HOB at 30 degrees and if the pressure still at or above 19 ophthalmology consult initiated. Time 7 if needed, see above If the patient has any increased reading at the end of the procedure, the same attending anesthesiologist in the post-operative recovery area prior to discharge will do a post op measurement. Any abnormal readings will prompt an ophthalmology consult and follow up with ophthalmology department. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
