title: Preliminary experience with ICI 35 868 as an i.v. induction agent: comparison with althesin.
abstract: In a small open dose-finding study the i.v. dose of ICI 35 868 required to induce anaesthesia in healthy adults was 2 mg kg-1. Comparison of this dose with Althesin 0.05 ml kg-1 for i.v. induction, both injected over 30 s suggests that they have similar effects on heart rate, arterial pressure and breathing. The mean times to loss of eyelash reflex were 57 +/- SD 10.1 s (ICI 35 868) and 46 +/- 3.9s (Althesin). The new drug was associated with pain and discomfort on injection in seven of 10 patients, but with less involuntary movement than occurred with Althesin.
