[The changes of intraocular pressure during sevoflurane anesthesia in children].

We investigated the intraocular pressure (IOP) during sevoflurane anesthesia in 20 children. We measured IOP, mean blood pressure and heart rate at 7 points in each subject. IOP was measured first after induction, then after vecuronium administration, immediately after intubation, and 5, 10, 15, 30 min after intubation. There were no significant changes in IOP and hemodynamics during sevoflurane anesthesia. We consider that the optimal time for IOP measurement is 5 or 10 min after intubation and the normal range of IOP is within the mean +/- 2 standard deviation. The peak values of IOP were 19.2 and 18.8 mmHg at 5 and 10 min after intubation. The results suggest that normal range of IOP is below 20 mmHg during sevoflurane anesthesia in children.
