Comparison of disposable and reusable laryngeal mask airways in spontaneously ventilating adult patients

Abstract

Recent studies have indicated that despite stringent sterilization processes, the reusable silicone laryngeal mask airway (LMA) has the potential for disease transmission through residual biological debris. As a result, a polyvinyl chloride (PVC) disposable LMA has been introduced. This randomized trial involved 138 spontaneously ventilating adult patients who underwent elective surgery requiring airway management with an LMA to determine whether there is a clinical difference between the disposable Portex® LMA (PLMA) and the standard reusable LMA in terms of ease of insertion, intra-operative cuff pressures and postoperative incidence of sore throat. There was no significant difference in f..
