[The intubating laryngeal mask: its advantages and limitations]

It has been hypothesized that the intubating laryngeal mask (ILM) has some advantages: (1) tracheal intubation is achieved with a neutral head-neck position and limited mouth opening, (2) intubation is not interfered with blood and secretion in the mouth, (3) ventilation via the device is possible, and (4) it is easy to use. Many studies have brought evidences for these points. Actually, cervical spine movement is unavoidable to a small extent although tracheal intubation is possible with a neutral head-neck position. Degree of hemodynamic changes and incidences of postoperative airway complications are similar between the ILM and the laryngoscope. ILM-users should pay attention to these limitations when they use the ILM.
