Remifentanil versus propofol sedation for peribulbar anesthesia.
The short onset and offset of remifentanil may allow for accurate dosing of sedative effect with few side-effects and rapid recovery. In this study, remifentanil is compared with propofol for sedation intraocular pressure hemodynamics and oxygen saturation, in patients undergoing cataract surgery with peribulbar block. After ethical committee approval, fifty patients scheduled for one eye cataract surgery were enrolled into the prospective study. Remifentanil infusion was initialized at a rate of 0.04 microg/kg/min, 10 min before peribulbar anesthesia in Remifentanil group (Group R). In Propofol Group (Group P), propofol infusion of 2 mg/kg/h was reduced to 1mg/kg/h. Intraocular pressures of the contralateral eye were measured before and after peribulbar anesthesia and at the end of the operation. Sedation scores (1-5), hemodynamic parameters and saturation were assessed at 5 minute intervals. Heart rate, intraocular pressure, saturation and sedation scores were similar between groups. Intraocular pressures decreased within time in both groups. There were significant changes in mean blood pressure after 5th min between groups (P < 0.05). The infusion of remifentanil or propofol for sedation provided adequate sedation, hemodynamic stability without increasing intraocular pressure during surgery in patients undergoing cataract surgery with peribulbar anesthesia.
