We undertook a single-blind, parallel-group, randomized controlled trial.The patients were randomized to either LMA Proseal group or LMA Supreme group by computer generated allocation.
The patients were scheduled for elective lateral positioned laparoscopic surgery, such as laparoscopic radical nephrectomy, laparoscopic renal cyst decortication (LRCD) or laparoscopic adrenalectomy.Inclusion criteria for the patients were: Aged>18 years, ASA physical status grade I - Ⅲ and body mass index ≤30 kg.m-2. Exclusion criteria were: anticipated difficult airway (e.g., Modified Mallampati Class IV, oropharyngeal pathology), severe cardiopulmonary disease, increased risk of regurgitation and aspiration (e.g., gastro-esophageal reflux disease, and pregnant patients), and retroperitoneal laparoscopic procedures.

Experimental: LMA Proseal group
The patients were randomly allocated to two groups by using computer-generated numbers.In LMA Prosealgroup,LMA Proseal was inserted into each patient after anesthesia induction.
Device: LMA Proseal
After preoxygenation, anaesthesia was induced with propofol, fentanyl and cisatracurium,LMA Proseal was inserted and cuff inflated in each group.
Experimental: LMA Supreme group
The patients were randomly allocated to two groups by using computer-generated numbers.In LMA Supreme group,LMA Supreme was inserted into each patient after anesthesia induction.
Device: LMA Supreme
After preoxygenation, anaesthesia was induced with propofol, fentanyl and cisatracurium ，LMA Supreme was inserted and cuff inflated in each group.
- oropharyngeal seal pressure between LMA Proseal group and LMA Supreme group [ Time Frame: intraoperative ]The equilibrating airway pressure was recorded when an audible leak occurred over the mouth.
- Ventilatory efficiency scores for the LMAs [ Time Frame: intraoperative ]
- Adverse effects in two groups [ Time Frame: intraoperative ]The adverse effects including regurgitation,hypoxemia,dysphonia,blood stained after LMA removal, and postoperative sore throat.
