Comparison of Laryngeal Mask Supreme^®, Softseal^®, Face-mask and Mouth-to-mouth Ventilation for Rescue Breathing during Basic Life Support: a Manikin Study

Abstract

  Laryngeal mask is a useful airway management device used during respiratory arrest. We compared the utility of laryngeal mask Supreme^® (SUPREME), Softseal^® (SOFTSEAL), face-mask, and mouth-to-mouth ventilation for rescue breathing with a manikin in 20 initial trainee doctors. Success rate on the first trial was significantly higher in the SUPREME trial than in the others. Time to perform effective ventilation was significantly shorter with mouth-to-mouth ventilation than with the other 3 devices. In contrast, the frequency of gastric inflation was significantly lower with the SUPREME than with the SOFTSEAL, face-mask and mouth-to-mouth ventilation. Our results suggest that the SUPREME may be useful for emergency rescue breathing.
