[Criteria for choice of an anesthetic technic for laryngeal laser microsurgery using the laser in adults].

Laryngeal microsurgery by means of the laser involves anesthetic constraints regarding mainly the mode of ventilation during operation. The principal techniques and different anesthetic protocols are discussed. The two main criteria for the choice of method appear to be the permeability of the laryngeal passage and the patient's general condition and history. The two principal methods proposed are high frequency jet ventilation and ventilation controlled by a protected intubation tube.
