[Personal experience of anaesthesia in ear surgery. Two year study].

Study of 168 cases of ear surgery, from September 1979 to September 1981. Various anaesthetic protocols were compared with a view to decreasing per-operative bleeding: --in 9 cases: Fluothane --in 11 cases: Alfatesine --in 89 cases: Neuroleptanalgesia --in 39 cases: Narcozep. The various proposals for controlled hypotension are discussed and the conclusion is drawn that, regardless of the method used, the percentage of failures was essentially identical and seemed to be related more to errors in assessment of the duration of the operation than to the drug used. A corollary to this attitude was the possibility of a 25% rate in delayed post-anaesthetic recovery.
