Background: Supreme laryngeal mask airway (SLMA) is a single use, new supraglottic airway device with anatomically designed curved airway conduit. It has second channel for gastric tube insertion. We compared the performance of the SLMA with that of the Proseal LMA (PLMA), the older reusable LMA, during anaesthesia in spontaneously breathing adult patients.
Methods: One hundred adult patients were studied in a prospective randomized controlled study. Insertion time, first attempt success rates, leak pressure, ease of gastric tube placement, and the incidence of blood staining on removal, as well as sore throat and hoarseness were compared. For statistical analyses, Student's t test, Mann-Whitney's U test, and Fisher's exact test were used where appropriate, and P<0.01 considered significant.
Results: SLMA provided faster insertion time (11 vs 18 seconds, P<0.01). Leak pressure was higher for PLMA (25 vs 28cmH2O, P<0.01). First attempt success rates, gastric tube placement and the incidence of complications were similar.
Conclusions: Our result indicated that SLMA can be inserted faster without inserting one's finger into patient oral cavity. Leak pressure was lower but acceptable for clinical use in spontaneously breathing anesthetized adult patients.
