Summary

Partial cuff inflation before insertion is generally used for laryngeal mask airway insertion in adult patients. However, it is not proven how much the cuff should be inflated. The aim of this study is to compare efficacy between the method using the resting volume and the method using half the maximum volume for partial cuff inflation.

Conditions

  • General Anesthesia

Interventions

PROCEDURE

The cuff inflation by the resting volume

80 patients are randomly allocated into two groups : resting volume group (n=40), half the maximum volume group (n=40). In the resting volume group, the pilot balloon valve is connected to syringe without piston for keeping the valve open to the atmosphere and allowing the pressure within the cuff of LMA to equalize with atmospheric pressure. In the half the maximum volume group, the cuff of LMA is completely emptied and then the cuff is filled with the half the maximum volume.
