Abstract:
The CO² -Laser has been efficient in excision of the vocal cords and larynx lesions. However, the ignition fine o f the endotraqueal tubes is a serious complication of the technique. Trying to avaliate the Jet-Venturi technique, 5 children forro 0 to 10 years old, of both sexes and with larynx pappilomata were undergone to laser ttratment using a metal neddle adapted to the suspended laryngoscope for ventilation. Propofol or etomidate with atracurium and alfetanil; or inhaled induction with halothane were usedin anestltesia. Periods of opnéia were coincidentes with thelaser beam with no variation in hemodinamics parameters or in the Sat O². The average time of surgery and awakeniug were 36,6 + /_ 3,1 and 13,3 + /-1, 45 minutes, respectively. Bradicardia was the unique complication observed. So, the ventilatory method was adequated in maintainingventilation, decreasing the fire complication and improving the surgeon's action.
