Comparing the Effects of Propofol and Dexmedetomidine Sedation on Intraocular Pressure

Abstract

We aimed to compare the effects of propofol and dexmedetomidine sedation on intraocular pressure in patients undergoing non-ophthalmic surgery with regional anaesthesia. Sixty patients; whom were scheduled for axillary plexus block and sedation for elective hand surgery, were randomly separated into two groups. Group P (n=30) received propofol 1 mg kg-1 iv as a loading dose and continued to receive 50-100 mg kg-1 dk-1 iv infusion at 10 min, as Ramsay sedation score were ensured to be 3-4. Group D (n=30) received dexmedetomidine 1 mg kg-1 hr-1 iv as a loading dose at 10 min, followed by a continuous 0.2-0.7 mg kg-1 hr-1 infusion while Ramsay Sedation Score were also ensured to be 3-4. Intraocular pressure of the patients were measured with “Tonopen XL applanation tonometer” before the sedative agent (control measurement), after the loading dose, at 15th, 30 th minute of operation and at the end of the operation. Propofol decreased intraocular pressure by 18.6% after the loading dose, 17.8% at the 15th minute, 21.7% at the 30th minute and 13.3% at the end of the operation. Dexmedetomidine decreased intraocular pressure by 34.1% after the loading dose, 36.4% at the 15th minute, 42.1% at the 30th minute and 40.1% at the end of the operation. When we compared two groups; the decrease in intraocular pressure was significantly different (p<0.05). Vomiting, nausea, allergic reaction, hypotension, bradycardy and apnea were not observed in any patient. Propofol and dexmedetomidine can safely be used in ophthalmic surgery as a sedative agent. Dexmedetomidine can be preferred as the first alternative as it has similar haemodynamic effects and more significantly reduces intraocular pressure.
