Comparison of Lary Seal Clear and Ambu Aura40 Supraglottic Airway Devices in Airway Management

Abstract

Supraglottic airway devices are widely used in modern anesthesia as effective alternatives to endotracheal intubation for routine airway management. Among these devices, the LarySeal Clear and Ambu Aura40 represent two commonly used laryngeal mask airway designs with different material properties, reusability profiles, and clinical features. The LarySeal Clear is a single-use transparent PVC device designed to reduce cross-contamination and allow visual monitoring of secretions, while the Ambu Aura40 is a reusable silicone-based device with an anatomically curved airway tube and reinforced tip to facilitate insertion and positioning. Both devices provide effective ventilation; however, they differ in cost, flexibility, sterilization requirements, patient comfort, and potential airway trauma. This mini-review aims to summarize the design characteristics, insertion techniques, advantages, limitations, and clinical applications of LarySeal Clear and Ambu Aura40 laryngeal mask airways in anesthesia practice.
