title: Comparison of the Ambu AuraFlex with the laryngeal mask airway Flexible: a manikin study.
abstract: OBJECTIVE
  The present study compared the Ambu AuraFlex and the laryngeal mask airway (LMA) Flexible with regard to time required for and success rates of insertion on a manikin by dental students who had never used an LMA. In addition, participants' views on ease of insertion of each device were surveyed.
  
  
  METHODS
  Subjects consisted of 30 dental students who inserted each airway device in a manikin. The time required for and success rates of insertion were measured. Subjects were then asked to rate the ease of insertion of each device using the 100-mm visual analog scale (from 0 mm = extremely easy to 100 mm = extremely difficult).
  
  
  RESULTS
  Insertion time was shorter with the Ambu AuraFlex (26.6 ± 7.1 seconds) than with the LMA Flexible (30.3 ± 6.8 seconds; P = .045). The rate of successful insertion using the Ambu AuraFlex (28 of 30 attempts, 93.3%) was greater than that with the LMA Flexible (23 of 30 attempts, 76.7%), although the difference was not statistically significant (P = .145). Ambu AuraFlex insertion was considered less difficult (median, 41 mm; 10th to 90th percentiles, 18 to 78 mm) than LMA Flexible insertion (60 mm; 42 to 82 mm; P = .004), as rated using the 100-mm visual analog scale.
  
  
  CONCLUSIONS
  The Ambu AuraFlex appears to be useful for inexperienced users because it enables quicker and easier insertion than the LMA Flexible.
