Propofol and alfentanil prevent the increase in intraocular pressure caused by succinylcholine and endotracheal intubation during a rapid sequence induction of anesthesia.
The increase in intraocular pressure (IOP) associated with succinylcholine (Sch) has made its use in patients with open globe injuries controversial. Studies that have examined techniques to prevent the increase in IOP due to Sch have shown a larger increase in IOP from the stimulus of laryngoscopy and endotracheal intubation. The purpose of our study was to examine whether the combination of propofol and alfentanil would prevent the increase in IOP due to Sch as well as endotracheal intubation during a rapid sequence induction of anesthesia. Sixty patients were randomized to receive either thiopental 5 mg/kg and Sch 1.5 mg/kg (Group I), propofol 2 mg/kg and Sch 1.5 mg/kg (Group II), or propofol 2 mg/kg, alfentanil 40 micrograms/kg, and Sch 1.5 mg/kg (Group III). The IOP was measured continuously from baseline awake (control) values until 15 s after successful intubation. All three groups had a significant decrease in IOP with the induction of anesthesia. Succinylcholine produced a consistent increase in IOP from the postinduction low in Groups I and II, but this increase was not significantly higher than baseline. The postintubation IOPs in Groups I and II were significantly higher than baseline (P < 0.001). During the entire study period, the IOP in Group III never increased above baseline. The IOP in Groups I and II had already begun to decline by 15 s postintubation, suggesting that laryngoscopy and intubation have the greatest effect on increasing IOP. We conclude that the combination of propofol and alfentanil prevents the increase in IOP from Sch as well as the increase associated with endotracheal intubation during a rapid sequence induction of anesthesia.

The effects of atracurium on intraocular pressure during steady state anaesthesia and rapid sequence induction: a comparison with succinylcholine.
The effects of atracurium 0.5 mg X kg-1 or succinylcholine 1.0 mg X kg-1 on intraocular pressure (IOP) were studied in ten patients during steady state nitrous oxide-oxygen-fentanyl anaesthesia. IOP was unchanged following atracurium but, one minute after succinylcholine, it had increased significantly (p less than 0.025) from 5.6 mmHg to 13.2 mmHg and remained significantly above control for 3 min. Twenty additional patients received either atracurium 0.75 mg X kg-1 or succinylcholine 1.0 mg X kg-1 as part of a rapid sequence induction, atracurium being administered prior to, and succinylcholine after, thiopentone. Intubating conditions were acceptable in all patients in both groups. Administration of thiopentone was associated with a significant (p less than 0.025) decrease in IOP. Although IOP increased in both groups as a result of laryngoscopy and intubation (from 8.0 mmHg to 12.1 mmHg in the atracurium Group and from 7.5 mmHg to 14.5 mmHg in the succinylcholine group) it did not exceed pre-induction IOP in the former. In the succinylcholine group, IOP after intubation exceeded pre-induction values for 2 min, although this increase was significant (p less than 0.05) only at the immediate post-intubation reading. It is concluded that atracurium in a dose of 0.75 mg X kg-1 is a suitable relaxant for use in rapid sequence induction.
