An evaluation of the Laryngeal Mask Airway Supreme™ in 100 patients

Department of Anaesthesia, National University Health System, Singapore

Summary

The Laryngeal Mask Airway (LMA) Supreme™ is a new supraglottic airway incorporating features of the LMA Proseal™, LMA Fastrach™ and LMA Unique™. We evaluated the LMA Supreme in 100 patients with normal airways having elective surgery. Our success rates of insertion and ventilation were 96% at the first attempt and 100% after two attempts. The median time to successful placement was 15 seconds (interquartile range 12 to 18 seconds). Forty-five patients breathed spontaneously and 55 patients had controlled ventilation. The incidence of blood staining on removal was 7% and 7% of patients had mild sore throat one hour postoperatively. One patient who had been placed in the left lateral position during surgery had left lingual nerve palsy postoperatively, which recovered completely after one month. Our findings suggest that in patients with normal airways, the LMA Supreme is easy to insert and provides a satisfactory airway with adequate seal pressures for ventilation.
