We report our further anaesthetic experience with Etomidate in 100 patients. The cardiovascular and respiratory systems were not significantly affected but intraocular pressure was reduced. ⋯ The myoclonic movements often seen with Etomidate anaesthesia were transient and have so far not created any major problem; they were reduced by a slower speed of injection but unaffected by diazepam premedication or pretreatment with low dose of a non-depolarizing muscle relaxant (pancuronium). Etomidate is a satisfactory alternative to thiopentone in situations where depression of the cardiovascular and respiratory systems are undersirable or where barbiturates are otherwise contraindicated and is a usefull addition to the induction agents in our anaesthetic practice.

The effects of enflurane-pancuronium anaesthesia on cardiovascular haemodynamics were studied before operation in six patients with valvular heart disease. A ten per cent decline in cardiac index and a 20 per cent decline in stroke volume were the only changes observed. Mean arterial, pulmonary arterial, contral venous, and pulmonary capillary wedge pressures were unaffected, as were systemic vascular resistance and pulmonary vascular resistance. The authors therefore conclude that enflurane-pancuronium anaesthesia causes only minimal cardiovascular depression in patients with valvular heart disease.
