Design outcomes

Primary

Measure	Time frame
Atracurium dosage. Timepoint: At the time of induction of anesthesia. Method of measurement: Milligram.;Ease of insertion of LMA. Timepoint: once. Method of measurement: The first attempt was made in 15 seconds and without the displacement = Easy, LMA In the first attempt needed more than 15 seconds, and need to LMA displacement = a bit of trouble, Need more than once trying to insertion of LMA, Need more than 30 seconds time And need to multiple LMA moves = quite difficult).;Air leakage around LMA. Timepoint: once. Method of measurement: Yes = audible sound At the time of patient manual ventilation. No = Lack of sound at the time of patient manual ventilation.;The number of attempts to insertion of laryngeal mask airway. Timepoint: During insertion of laryngeal airway mask. Method of measurement: The number.	—
