Comparison of the intubating laryngeal mask airway versus laryngoscopy in the Bell 206-L3 EMS helicopter.

摘要: Abstract Introduction The purpose of this study is to compare intubation success rate and time for the intubating laryngeal mask airway (I-LMA) versus direct laryngoscopy (DL) using a manikin model during simulated in-flight scenario. Setting setting was University hospital-based air medical program. Methods This prospective, randomized, crossover trial. Eight nurses 7 paramedics were randomly assigned perform 3 intubations with either I-LMA or DL first then alternate technique. Descriptive statistics, 95% confidence intervals (CIs) means, Fisher's Exact test conducted comparisons. Results Fifteen set-ups 45 performed each Previous experience 74 mm (95% CI 64-84) 18 9-27) I-LMA. Set-up 33 seconds 26-40) 40 29-50) Time 12 10-14) 39 31-48) Success 100% placement 98% through Crew rated difficulty 13 6-20), placing 23 13-32), 17 10-24). Conclusion Intubation very high both I-LMA, despite less flight crew Total longer but still than 1 minute. crews considered techniques easy perform. appears be useful adjunct management in Bell 206-L3 helicopter.
