title: Comparison of i-gel™ supraglottic device with classic laryngeal mask airway in anesthetized paralyzed children undergoing elective surgery.
abstract: BACKGROUND
  The newest variation of the i-gel supraglottic airway is a pediatric version.
  
  
  OBJECTIVE
  This study was designed to investigate the usefulness of the size 2 i-gel compared with the classic laryngeal mask airway (cLMA) of the same size in anesthetized, paralyzed children.
  
  
  METHODS
  A prospective, randomized, single-blinded study was conducted in tertiary care teaching hospital.
  
  
  METHODS
  Sixty ASA grade I-II patients undergoing lower abdominal, inguinal, and orthopedic surgery were included in this prospective study. The patients were randomly assigned to i-gel and cLMA groups (30 patients in each group). Size 2 supraglottic airway was inserted according to the assigned group. We assessed ease of insertion, hemodynamic data, oropharyngeal sealing pressure, and postoperative complications.
  
  
  METHODS
  Parametric data were analyzed with the unpaired t-test and non-parametric data were analyzed with the Chi-square test. Unless otherwise stated, data are presented as mean (SD). Significance was taken as P < 0.05.
  
  
  RESULTS
  There were no differences in the demographic and hemodynamic data among the two groups. The airway leak pressure of the i-gel group (26.1 ± 2.4 cm H2O) was significantly higher than that of the cLMA group (22.64 ± 2.2 cm H2O). The success rates for first attempt of insertion were similar among the two devices. There were no differences in the incidence of postoperative airway morbidity among the two groups.
  
  
  CONCLUSIONS
  Hemodynamic parameters, ease of insertion, and postoperative complications were comparable between the i-gel and cLMA groups, but airway sealing pressure was significantly higher in i-gel group.
