For orotracheal intubation

B. Neuromuscular blockers provide prompt flaccid paralysis to facilitate orotracheal intubation. The preferred agents for this purpose are rapid-onset agents such as succinylcholine, rapacurium, mivacurium, rocuronium, and vecuronium. They also are used to treat laryngospasm.

When exposure to 1,1,1-trichloroethane ceases, regardless of route of exposure, the compound is rapidly cleared from the body, predominantly by exhalation of unchanged 1.1.1-trichloroethane in expired air (see Section 2.3.). Very little metabolism of the compound takes place, and despite a preferential distribution of absorbed 1,1,1 -trichloroethane to fatty tissues, significant retention does not occur without continued exposure. Thus, continued ventilation by the lungs will eliminate the compound from the body. Suggested methods to assist in lung ventilation include orotracheal and nasotracheal intubation for airway control and positive pressure ventilation techniques (Bronstein and Currance 1988 Ellenhorn and Barceloux 1988).
