[The laryngeal mask].
The laryngeal mask (LM) is a new concept developed by Brain. Easily inserted, the LM allows appropriate ventilation without the disadvantages of either the facial mask or the endotracheal intubation with its own complications. The limits of its use concern all the cases of reduction of thoracopulmonary compliance and full stomach. The LM offers no protection against regurgitation and aspiration. Airway obstruction may occur following laryngospasm (light anaesthesia) or down folding of the epiglottis. Trauma to the uvula and the posterior pharyngeal wall have been reported. The LM may be useful in all cases of surgery in which intubation is not absolutely required. Moreover, the LM is widely used for ENT and ophthalmic surgeries, in paediatric and adult procedures. Many cases of foreseeable or unforeseeable difficult intubation have been resolved by the insertion of a LM, allowing secondary intubation through the mask. Further investigations are required in order to evaluate the real limits and indications for its extended use.
