Comparison of Air-Q^® Masked Laryngeal Airway and Standard Endotracheal Tube during Gynecological Laparoscopic Surgery

Magdy Imam

Background: In laparoscopic surgical procedures, many clinicians recommend extra glottic airway devices as good alternatives to intubation. We compared the air-Q® and standard Endotracheal tube (ETT) during laparoscopic gynecological surgery regarding hemodynamics changes and respiratory parameters before, during, and after pneumoperitoneum.

Methods: Following Institutional Review Board approval and written informed consent, 60 patients were randomly allocated into the air-Q group (n=30) or ETT group (n=30). The hemodynamic parameters and peak inspiratory pressure, lung compliance, were measured before, during, and after pneumoperitoneum.

Results: There were no significant differences between the two groups regarding demographic data, hemodynamic parameters ware significantly changed in EET group, Peak inspiratory pressure and lung compliance were not significantly changed following carbon dioxide pneumoperitoneum in both groups.

Conclusions: Air-Q can be a good alternative to intubation in selected groups of patients in laparoscopic gynecological procedures, especially where the avoidance of the presser response is of particular concern, and in an emergency unexpected difficult airway.
