Comparison of cuff-pressure changes in silicone and PVC laryngeal masks during nitrous oxide anaesthesia in spontaneously breathing children
Background. The purpose of this study was to evaluate the cuff pressures of four different laryngeal masks in paediatric patients undergoing routine surgery and to determine whether there is a substantial increase in cuff pressure when silicone masks are used compared to PVC laryngeal mask airways. Methods. Hundred and forty patients aged < 16 yr were randomly allocated to receive one of four extraglottic airway devices: LMA-Classic; LMA-Unique; Soft Seal; or Cobra-PLA.
