The effects of different doses of remifentanil on intraocular pressure after tracheal intubation: A randomized, double-blind and prospective study

We investigated the effects of alfentanil and different doses of remifentanil on intraocular pressure (IOP) and hemodynamic responses during laryngoscopy and endotracheal intubation in 60 patients. IOP values decreased significantly from 30 seconds before the intubation to 5 minutes after intubation measurements compared to baseline values in all the groups. However, a significant increase in 1OP was recorded in the 0.5-mu g remifentanil group after tracheal intubation.
