| description | 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 first attempt insertion success rates (79% vs 84%) or difference in the incidence of postoperative sore throat observed between the two groups. Cuff pressure increases with nitrous oxide anaesthesia were significantly larger with the reusable LMA. The disposable PLMA provided a suitable airway in spontaneously ventilating patients without the risk of disease transmission inherent in a reusable device. |
