Summary

Overinflation of laryngeal mask airway cuff increase side effect like hoarseness, vocal cord paralysis, sorethroat. The investigators will study correlation between laryngeal mask airway cuff volume and pressure and physical examination of head and neck.

Conditions

  • Anesthesia

Interventions

DEVICE

Classic laryngeal mask airway

1. measurement of head and neck * Ht,Wt,BMI, neck circumference above a thyroid cartilage, mandible circumference( from the lower part of earlobe-mandible angle-mentum-mandible angle to the lower part of earlobe), neck length (mastoid tip\~sternal notch), modified mallampati classification under sitting position, thyromental distance. 2. laryngeal mask airway insertion and measuring cuff pressure by pressure transducer * \# 4.0 for female, #5.0 for male * initial cuff volume(air) : maximum volume recommended by the manufacturer * check pressure : if it exceed 60cmH20, we will remove air until 60cmH20 * remove air until gas leak occured around the cuff under airway pressure 15cmH20, fresh gas flow 6liters/min. Check the volume and pressure just before leakage occured.
