Purpose Of Review:
To present recent advances in the role of the laryngeal mask airway (LMA) and its newer modifications in the management of difficult airway.
Recent Findings:
The principles of management of a difficult airway remain the same, but the advent of the intubating LMA (ILMA) and Proseal LMA (PLMA) has provided a better choice in such situations. While fiberoptic intubation remains the preferred choice of many anaesthesiologists, the ILMA provides equal or better conditions for intubation when compared with the awake technique. The PLMA with its better safety profile is proving valuable in the emergency scenario.
Summary:
ILMA and PLMA have been shown to be effective in the management of difficult airway. We recommend that training in the use of these devices be made mandatory.

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,...
