orotracheal intubation without the use of muscle relaxant: propofol or etomidate in combination with remifentanil*

An appropriate tracheal intubation requires the patient who goes under this procedure to allow the manipulation of cervical, maxillofacial and laryngeal pharynx in order to be able to visualize the glotis.1 The use of neuromuscular relaxants is quite helpful when trying to attain this objective.2 Its use has become so widely applied that it is basically now the only technique known and taught to anesthesiologists.
