Randomized Controlled Trial Comparative Study Clinical Trial
Insertion of the LMA-Unique with and without digital intraoral manipulation by inexperienced personnel after manikin-only training.
In a randomized, crossover study, we compared insertion of the LMA-Unique with and without digital intraoral manipulation by inexperienced personnel after manikin-only training. Ten registered nurses with no hands-on clinical experience of airway management and 100 anesthetized, paralyzed adults (ASA Status 1-2, aged 18-80 years) participated in the trial. Training comprised: 1) a 30-min didactic lecture; 2) a 3-min description of each of the insertion techniques; 3) a 3-min demonstration of each technique using a manikin; 4) 10 min of supervised training on the manikin with each technique. ⋯ There were no differences in performance among nurses. We conclude that insertion of the LMA-Unique is equally successful with or without digital intraoral manipulation by inexperienced personnel in paralyzed adults after manikin-only training. Successful insertion of the LMA-Unique does not require insertion of the finger into the patient's mouth.
