Comparison of the Air-Q®sp versus the LMA® Supreme™ in patients undergoing laparoscopic gynecologic surgery: a single-blind, randomized controlled trial.

Previous studies have reported the clinical utility of the LMA® Supreme™ (LMA Supreme) in laparoscopic surgery under general anesthesia, but there has been limited research on the effectiveness of the self-pressurized Air-Q® (Air-Q) in this clinical context. This study assessed the clinical performance of the Air-Q in laparoscopic gynecological surgeries by comparing its effectiveness, particularly in terms of oropharyngeal leak pressure (OLP), against that of the LMA Supreme. Fifty-two female patients (American Society of Anesthesiologists class I--II) scheduled for laparoscopic gynecologic surgery were randomly assigned to either the Air-Q group or the LMA Supreme group. The primary outcome was OLP, and secondary outcomes included the number of attempts required for device insertion, the time taken for insertion, difficulty of insertion, leakage rate, and complications associated with supraglottic airway device use. The Air-Q group exhibited a significantly lower OLP compared to the LMA Supreme group (19.5 ± 4.1 cmH2O vs. 23.2 ± 6.0 cmH2O, p = 0.011), with a mean difference of -3.8 cmH2O (95% confidence interval, -6.6 to -0.9 cmH2O). Analysis of secondary outcomes revealed no significant differences between the two groups. LMA Supreme could be preferred over Air-Q for airway management during general anesthesia in patients undergoing laparoscopic gynecologic surgery primarily due to its higher OLP. However, the Air-Q remains a viable alternative, exhibiting no significant differences in leakage rates compared to LMA Supreme. [ABSTRACT FROM AUTHOR]
