Meanwhile, some drawbacks limit the application of LMA in infants, such as upper airway semi-obstruction, air leakage and gastric air insufflations. The study was designed to compare the efficacies of the LMA-I-gel and the LMA-Ambu in infant under one-year-old during general anesthesia by using continuous airway monitoring technique. Methods thirty infant, ASA I, aged 1 month to 1 year, undergoing urologic surgical procedures were randomly divided into two groups. LMA-I-gel and LMA-Ambu were inserted in group I and A (n=15 in each), respectively. Main outcome measures: Inserting time, Achievement ratio of insertion, classification after bronchoscope of Fiber Optic Bronchoscope (FOB), air
