Abstract
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 SGAs have been designed to provide a better seal of the airway and are relatively safer since they allow gastric aspiration. Thus, the SGAs may be the most versatile component in the airway management cart. Existing literature on SGAs tends to focus on first generation SGAs 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. This chapter addresses various types of commercially available novel SGAs and their use in and out of hospital settings.
Highlights
In spite of tremendous advances in contemporary anaesthetic practice, advances in airway management continue to be of paramount importance to anaesthesiologists
Careful observations and clinical experience have led to several modifications of the laryngeal mask airway (LMA) leading to development of newer supraglottic airway devices with better features for airway maintenance [3]
The Aintree catheter, a modification of the Cook’s airway exchanger may be used to intubate through the supraglottic airway (SGA). It is loaded over a fiberoptic bronchoscope (FOB) and the trachea is visualised through the SGA [30, 31]
Summary
The Baska Mask® (Baska Versatile Laryngeal Mask Pty Ltd., Australia) has been designed by Australian anesthesists, Kanag and Meenakshi Baska. It obviates the need of an orogastric tube and replaces this with a sump and two drains. It brings together features of PLMA, SLMA, SLIPA and i-gel. The biggest advantage of Baska mask lies in the fact that cuff deflation or inflation is not required prior to insertion [97]
