The Comparison of Two Different Methods of Partial Inflation of Cuff for Facile Insertion of Laryngeal Mask Airway in Pediatric Patients

Partial cuff inflation before insertion is generally used for laryngeal mask airway insertion in children. 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.
