Randomized Controlled Trial Comparative Study
Comparison between LMA-Classic and AMBU AuraOnce laryngeal mask airway in patients undergoing elective general anaesthesia with positive pressure ventilation.
The LMA-Classic laryngeal mask airway (Classic LMA) is an autoclavable and reusable laryngeal mask airway with strong evidence supporting its efficacy and safety. Due to the concern of infection risk particularly of prion disease, various single-use laryngeal mask devices were developed. The Ambu AuraOnce LMA (Ambu LMA) is a single use disposable laryngeal mask airway with special design that conforms better to the anatomy of the airway. ⋯ This study demonstrated that the Ambu LMA was comparable to the Classic LMA in terms of the ease of insertion, but provided better seal during positive pressure ventilation with less postoperative sore throat.
