Summary
Brief summary (as posted)
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

- TIVA anesthesia
- description
- Induction with 1% propofol (2-3 mg/kg), fentanyl (1-3 mg/kg), and Rocuronium 1-1.5 mg/kg. Before the injection of propofol, 5 mL 1% lidocaine (50 mg) to limit any discomfort caused by the propofol injection. After endotracheal intubation, intravenous infusion of propofol, lidocaine, ketamine or narcotic as deemed appropriate by anesthesiologist. There will be no inhalation anesthetic used. Ventilation with oxygen and air mixture (50%/50%) and titrated to keep the mean arterial pressure within 20% of its preinduction value. Muscle relaxation maintain using Aliquots of rocuronium to 0 to 1 train-of-4 twitch response of adductor pollicis. During surgery, mechanical ventilation using pressure-controlled mode (peak inspiratory pressure 30 cm H2O). We aim for Tidal volume of 5-7 ml/Kg of ideal body weight with a positive end-expiratory pressure of 5 cm H2O, and a respiratory rate to maintain end-tidal carbon dioxide between 30 to 40 mm Hg.

Before the injection of propofol, 5 mL 1% lidocaine (50 mg) to limit any discomfort caused by the propofol injection. After endotracheal intubation, the depth of anesthesia will be maintained at a minimum alveolar concentration of 1 to 1.25 using isoflurane in oxygen and air mixture (50%/50%) and titrated to keep the mean arterial pressure within 20% of its preinduction value. Muscle relaxation maintain using Aliquots of rocuronium to 0 to 1 train-of-4 twitch response of adductor pollicis. During the surgery, subjects will be mechanically ventilated using pressure-controlled mode (peak inspiratory pressure 30 cm H2O). We aim for Tidal volume of 5-7 ml/Kg of ideal body weight with a positive end-expiratory pressure of 5 cm H2O, and a respiratory rate to maintain end-tidal carbon dioxide between 30 to 40 mm Hg.
