[Value of jet ventilation during otorhinolaryngologic endoscopies practiced under general anesthesia].

A technique of jet ventilation under general anesthesia (Alfaterinse suxamethonium) was used in 67 patients, in 55 cases for multiple endoscopic examinations in a single stage, usually laryngoscopy in suspension followed by oesophagoscopy, and in 12 cases, for an operation on the larynx. Arterial gasometry (PaO2 and PaCO2) proved the efficacy of the method, the major risk remaining, in the opinion of the authors, the possibility of excessive pressure which may be avoided by strict supervision.
