Remifentanil prevents an increase in intraocular pressure after succinylcholine and tracheal intubation

We have studied changes in intraocular pressure (IOP) in 30 patients after succinylcholine (suxamethonium) and tracheal intubation following administration of propofol 2 mg kg(-1) and either remifentanil 1 mu g kg(-1) (group R) or saline (group S). IOP was measured be-fore induction, before administration of succinylcholine and the study drug, before intubation and for every 1 min after intubation for 5 min. There was a significant decrease in IOP in group R compared with group S from the time of administration of the study drugs to the end of the study (P<0.006).
