BACKGROUND: The authors studied the effects of sevoflurane on intraocular pressure (IOP) after induction in children undergoing either tracheal tube (TT) or laryngeal mask airway (LMA) insertion without a muscle relaxant. METHODS: The study included 38 children. Anesthesia was induced (8%) and maintained (3-4%) with sevoflurane in 100% O2. No muscle relaxants were used. A TT was inserted in group I (n = 20), and an LMA in group II (n = 18). IOPs were measured after induction, insertion of TT or LMA and at one, two, and three minutes thereafter. The heart rate and mean arterial pressures were also recorded. RESULTS: IOP increased significantly in group I after TT (p < 0.01) and remained high until after three minutes. The pressures were similar in the LMA group at all measurements. CONCLUSIONS: Sevoflurane does not prevent the increase in IOP after intubation without muscle relaxants. LMA does not increase IOP in children after sevoflurane induction.
