hemodynamic changes are major hazards of general anesthesia and are probably generated by direct laryngoscopy and endotracheal intubation. we designed this prospective randomised study to assess the cardiovascular changes after either laryngeal mask airway (lma), face mask (fm) or endotracheal tube (ett) insertion in the airway management of adult patients anesthetised with nitrous oxide and ha...

Fiberoptic-compatible oral airways (FCOAs) combine the simplicity and benefits that traditional oral airways provide, with the advantage of mechanically guiding fiberoptic intubation. This review examines and compares the salient properties of these devices. Of note, the clinician should pay particular attention to the location and depth of the channel. FCOAs, with an anterior channel, may be a...

The laryngeal mask airway (LMA) was invented by Dr. Archie Brain at the London Hospital, Whitechapel, in 1981. Dr. Brain's main objective for the LMA was that it would provide a better method of maintaining a patient's airway than by face mask. Also, the LMA would be less hemodynamically stressful than with insertion of an endotracheal tube. The LMA consists of a silicone rubber tube connected ...

We report the successful use of a ProSeal laryngeal mask airway (PLMA) as a dedicated airway to allow fibre-optic inspection and passage through a tightly stenosed glottic and subglottic lesion, before fibre-optic-guided transtracheal placement of a Ravussin needle and jet ventilation. The described technique avoided both tracheostomy and the potential of 'seeding' the tumour by passage of the ...

Management of difficult tracheal intubation has been facilitated by different techniques which include the use of stylets, introducers, intubating laryngeal mask airway, as well as by the development of special laryngoscope blades and fiberoptic laryngoscopes. The most recent advances for facilitation of difficult tracheal intubation is the introduction of the video-assisted laryngoscopes. The ...

Objectives: The recent introduction of a disposable laryngeal mask airway has provided paramedics with an alternative to endotracheal intubation. Time taken to secure the airway with each device was compared in patients undergoing elective surgery. Methods: Patients undergoing general anaesthesia were studied. Paramedics trained in laryngeal mask use and endotracheal intubation participated in ...
