This study aimed to compare the clinical effects of the Medis flexible laryngeal mask airway (FLMA) with those of the Ambu AuraFlex FLMA in pediatric ophthalmic surgery. A total of 80 patients, aged 1 to 5 years, in American Society of Anesthesiologists I–II, weighing ≥10 kg, and without any existing airway difficulties, were enrolled in this study. The patients were randomly divided into Group M (Medis FLMA) and Group A (Ambu AuraFlex FLMA). The time of insertion, number of attempts, finger assistance required, manipulation, oropharyngeal leak pressure (OLP), fiberoptic grade of view, and complications such as bloodstaining, hoarseness, and sore throat were recorded. Group M showed a significantly higher OLP than did Group A ( P = .002); however, Group M required more finger assistance than did Group A ( P = .009). There were no statistically significant differences between the 2 groups in terms of insertion time, number of attempts, manipulation, fiberoptic view grade, or complications. Both the Medis and Ambu AuraFlex FLMA can provide smooth ventilation during pediatric ophthalmic surgeries. The Medis FLMA showed a higher OLP than did the Ambu AuraFlex FLMA but required more finger assistance during insertion.

Lightwand-Guided Insertion of Flexible Reinforced Laryngeal Mask Airway: Comparison with Standard Digital Manipulation Insertion

et al. 2020

Background The flexibility of the long flexometallic tube makes insertion of the flexible reinforced laryngeal mask airway (f-LMA) difficult. We compared the usefulness of rigid lightwand-guided f-LMA insertion with standard digital manipulation. Material/Methods Fifty-four patients (aged 19–70 years) were randomly divided into a control group (digital manipulation technique) or the lightwand group (lightwand-guided insertion technique). The insertion profiles, oropharyngeal leak pressure (OLP), peak inspiratory pressure (PIP), expiratory tidal volume, and ventilatory score were measured in patients with neutral, extension, rotation, flexion, and re-neutral head-neck positions in turn. Results The success rate and ease of insertion did not differ between groups, but the insertion time was longer in the lightwand group. The fiberoptic laryngeal view was significantly better in the lightwand group than in the control group. However, the OLP, PIP, expiratory tidal volume, and ventilatory scores were not significantly different between groups according to head-neck positions. The extension posture was associated with a significant negative effect on ventilation, but ventilation returned to initial levels with the other postures. Conclusions Lightwand-guided f-LMA insertion showed a better fiberoptic laryngeal view than standard digital manipulation, but no improvement in the ventilatory state was observed due to position. Therefore, lightwand-guided insertion could facilitate correct placement of the f-LMA, but it has limited clinical usefulness.
