Second Generation Supraglottic Airway (SGA) Devices.
reusable model, maximum 40 times
Supraglottic Airways (SGAs) are an integral part of anaesthetic care. Since their introduction, several modifications, additions, and variations have been developed and are currently in clinical practice since the last 25 years. Not only are they useful for difficult ventilation during both in-hospital and out-of-hospital difficult airway management, they also act as a conduit for tracheal intubation. The newer or second-generation Supraglottic Airways have been designed to provide a better seal of the airway and are relatively safer since they allow gastric aspiration. Thus, the Supraglottic Airways may be the most versatile component in the airway management cart. Existing literature on Supraglottic Airways tends to focus on first generation Supraglottic Airways and their use in OT only. However, the scope and use of these devices is vast. Knowledge regarding specific devices and supporting data for their use is of utmost importance to patient’s safety.
Removal technique
Wait for full recovery from anaesthesia. Do not try to pull out the Supraglottic Airways if the patient is biting down on the shaft. Usually, patients emerge smoothly with Supraglottic Airways.
It is recommended to use a bite block with the LMA in order to prevent damage to the airway tube or pilot balloon during emergence. Manufacturers usually recommend using a wad of gauze swabs rolled into a cylindrical shape and placed along the LMA. Some anaesthesiologists prefer to place the Guedel’s airway. The LMA should never be removed if patient is in a light plane of anaesthesia as it may precipitate a laryngospasm
