CONTROLLED VENTILATION FOR CEREBRAL ANGIOGRAPHY

Summary: Various techniques of general anaesthesia were studied in sixty patients undergoing cerebral angiography to determine the separate influences of arterial carbon dioxide tension, controlled ventilation and trichloroethylene upon the quality of the films obtained. A low carbon dioxide tension and controlled ventilation both increased the probability of high quality films. The use of trichloroethylene did not appear to affect film quality. Anaesthesia for cerebral angiography is discussed and it is concluded that moderate hyperventilation under nitrous oxide and tubocurarine anaesthesia resulted in high quality films with the greatest diagnostic value. © 1969 John Sherratt and Son Ltd.
