Sodium cyanide was infused intravenously in 11 lightly anaesthetised and spontaneously breathing M. mulatta. In most, the EEG, ECG, respiratory rate, blood pressure, cerebral venous sinus pressure, end-tidal pCO2 and body temperature were recorded. Blood gases, pH, lactate and pyruvate were estimated in arterial and venous sinus blood samples. There was an initial hyperventilation with tetany in all animals. A rapid rate of cyanide infusion led to apnoea. An isoelectric or near-isoelectric EEG was usually precipitated by bradycardia often with additional hypotension. Neither epileptic seizures nor their EEG concomitants were seen at any stage. Three animals died of early heart failure. Brain damage was seen in 4 animals surviving up to 98 hr. White matter was involved in all. Ischaemic neuronal alterations, restricted to the striatum of one animal, were attributed to major circulatory complications. It was concluded that under these experimental conditions there is no evidence for hypoxic neuronal damage of purely histotoxic type.
