[Use of total myorelaxation for placing a laryngeal mask and further artificial lung ventilation].

The specific features of placing a laryngeal mask (LM) under total myoplegia were studied. The first attempt at placing LM was successful in 98.7% of cases. A pressor response to LM appeared as increases in heart rate by 5.6% with combined intravenous ketamine anesthesia used during laparoscopic cholecystectomies (Group 1), by 10.2% at saphenectomies (Group 2), and by 6.7% with barbiturates. When diprivan was used, changes were absent in Group 1, there were increases in mean blood pressure and heart rate by 10 and 6.6%, respectively, in Group 2. The response to tracheal intubation was significant under all types of anesthesia. Regurgitation and aspiration were absent in all groups. The use of total myoplegia to place LM allows different current anesthetics to be used in the optimal doses and the procedure for placing LM to be greatly simplified.
