title: A randomised trial to compare i-gel and ProSeal™ laryngeal mask airway for airway management in paediatric patients.
abstract: OBJECTIVE
  i-gel™ is a newer supraglottic airway device with a unique non-inflatable cuff. We aimed to compare i-gel™ with ProSeal™ laryngeal mask airway (PLMA™) in children scheduled for surgery under general anaesthesia (GA) with controlled ventilation.
  
  
  METHODS
  This prospective, randomised controlled study was conducted in 100 surgical patients, aged 2-6 years of American Society of Anesthesiologists Physical Status I-II scheduled under GA. Patients were randomly allocated to receive either size 2 i-gel™ or PLMA™ as an airway device. The primary aim was oropharyngeal leak pressure assessed at 5 min following correct placement of the device. Secondary outcomes measured included number of attempts, ease of insertion, time of insertion, quality of initial airway, fibre-optic grading and effects on pulmonary mechanics. Statistical analysis was done using pairedt-test and Chi-square test.
  
  
  RESULTS
  The demographic data were similar in both the groups. The oropharyngeal leak pressure in the i-gel™ group was 29.5 ± 2.5 cmH2O as compared to 26.1 ± 3.8 cmH2O in PLMA™ group (P= 0.002). The time taken for successful insertion in PLMA™ was longer as compared to i-gel (12.4 ± 2.7 vs. 10.2 ± 1.9 s,P= 0.007). The quality of initial airway was superior with i-gel™. The number of attempts, ease of insertion of supraglottic device, insertion of orogastric tube and pulmonary mechanics were similar in both the groups.
  
  
  CONCLUSIONS
  Size 2 i-gel™ exhibited superior oropharyngeal leak pressure and quality of airway in paediatric patients with controlled ventilation as compared to PLMA™ although the pulmonary mechanics were similar.
