Abstract:
BACKGROUND:Air-QⓇ laryngeal mask airway (LMA) is a second-generation supraglottic airway device (SAD) providing adequate airway control despite the unfavorable airway anatomy in children. Several studies have assessed it as a conduit for tracheal intubation and compared its efficacy with that of other SADs, but there are no studies comparing the laryngeal view with midline and rotational insertion techniques of Air-Q. Therefore, this study compared the fiber-optic bronchoscopic (FOB) assessment of the Air-Q position using these two insertion techniques.
METHODS:This randomized controlled trial included 80 patients of the American Society of Anesthesiologists physical status I/II of either sex (age group 5–12 years, weight 10–30 kg), who were scheduled for elective surgery in the supine position under general anesthesia. The patients were randomly subjected to rotational and midline technique groups (n = 40, each), and appropriate sized Air-Q, based on the weight of the patient, was inserted using the technique allocated to each patient. Time taken and number of attempts for successful insertion of the devices and any complications after removal of device were studied.
RESULTS:FOB grade 1 (ideal position) was seen in 29/40 (72.5%) and 19/40 (47.5%) children subjected to the rotational and classic midline techniques, respectively (P = 0.045). The time taken to successfully insert the Air-Q was significantly lesser in the rotational technique group (7.2 ± 1.5 s) than in the classic midline technique group (10.2 ± 2.1 s) (P < 0.001), whereas complications were similar in both groups.
CONCLUSIONS:The rotational technique was associated with better FOB view, and was faster than the classic midline technique of Air-Q insertion in pediatric patients.
