Abstract:
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.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
