Thalamonal for Laryngomicrosurgery / 대한마취과학회지

ABSTRACT

Microsurgery of the larynx using direct laryngoscopy is becoming an increasingly popular technique for the otorhinolaryngologist. Many techniques of anesthesia have been developed for these procedures but they all have the same drawbacks. General anesthesia with endotracheal intubation decreases the field of vision for the surgeon or it requires unusual surgeon anesthetist co-operatives. Therefore neuroleptic analgesia has been adapted to the suspension laryngoscope. Because of the greater stability of the circulatery and respiratory systems associated with their use. Thalamonal(droperidol 2.5mg/ml with fentanyl 0.05mg/ml) was found to be preferable to other anesthstic for the production of neuroleptic analgesia. Thus in 28 patients requiring laryngomicrosurgery in Severance hospital duriag the past 4 years(May, 1975-March, 1979), a butyrophenon derivative, droperidol and fentanyl has been used for the production of neuroleptic analgesia. Consequently. we concluded that, in most cases of suspension laryngoscopy, we could gain a good analgesic and anesthetic condition with 3.02ml(mean value) Thalamonal adveres action for a 55 minute(mean value) operation without remarkable undesirable adveres effects. In addition to this. this technique was of great benefit to the operator, because not only the patient awake during operation and cooperative to the operation but also vocal cord mobility can be observed during the operation.
