Summary
One important goal in anesthetic management during ocular surgery is to provide adequate control of intraocular pressure (IOP). An increase in IOP may be catastrophic in patients with glaucoma or a penetrating open-eye injury. There is an ongoing debate over the effect of anesthetic agents on the IOP. Anesthetic regimens in this surgical field commonly consist of short-acting anesthetic agents, such as propofol and sevoflurane, usually combined with short-acting analgesics, such as remifentanil. Both propofol and sevoflurane are known to reduce the IOP. To this end there is no data in the literature to support or disprove this finding. Study Hypothesis Variations in the end-tidal sevoflurane concentrations have no significant effect on the IOP.
