LMA versus Air Q

Details and patient eligibility

About

Nowadays, supraglottic airway devices are simple and effective alternatives to endotracheal intubation. Both laryngeal mask airway LMA and air-Q airway are supraglottic airway devices that can be used to maintain and protect airways from aspiration of secretions and blood during DCR surgery. The present study was designed to compare standard LMA versus air Q as regards the sealing effect and aspiration of blood in DCR surgery.

Full description

72 patients were divided into two groups, 36 patients each, named LMA group, and air Q group according to supraglottic devices used. The following parameters were recorded in both studied groups, continuous Electrocardiography (ECG), heart rate (HR), means arterial pressure (MAP), arterial oxygen saturation (SpO2), end tidal carbon di-oxide (PCO2)..Oro pharyngeal leak pressure in (cmH2O), exhaled tidal volume in (ml), leak volume in (ml), leak fraction in (%) number of shifting from LMA to air Q or ETT and shifting from air Q to LMA or ETT was recorded with absence or presence of surgical blood on The undersurface of the device used.
