Comparison of Cuff Pressure Increase upon Nitrous Oxide Exposure in air-Q Single Use, LMA-Supreme, and LMA-ProSeal; a Simulation Study

Purpose: A simulated lung model was used to compare the nitrous oxide-mediated increase in cuff pressure among three supraglottic devices air-Q® laryngeal airway single use (air-Q), LMA-Supreme® (Supreme), and LMAProSeal ®(ProSeal).

Methods: The cuff pressure was initially adjusted to 10, 20, and 30 cmH2O. We changed the flow from without nitrous oxide (nitrous oxide 0%, oxygen 100 %) to with nitrous oxide (nitrous oxide 80%, oxygen 20%).

Results: The cuff pressure of air-Q, Supreme and ProSeal were measured 15 and 30 minutes later. The cuff pressure of the air-Q and Supreme was significantly lower than that of the ProSeal after 15 and 30 minutes, regardless of the initial pressure (P<0.05). air-Q also showed significant lower cuff pressure than Supreme (P<0.05).

Conclusion: These findings suggest that the air-Q may be more effective for preventing hyperinflation of cuff in response to nitrous oxide exposure.
