[Difficult tracheal intubation and abnormal response to thiopental in a patient with arthrogryposis multiplex congenita].

Anesthesia was administered for six times to a patient with arthrogryposis multiplex congenita (AMC) at the age of 10 to 17 years. In the first four occasions of anesthesia, difficult tracheal intubation was encountered due to limited neck extension, inadequate mouth opening and the short epiglottis. On the fifth anesthesia, the patient remained conscious even after intravenous injection of thiopental 6.6 mg.kg-1, and enflurane in combination with nitrous oxide was administered to induce anesthesia. During the induction of the sixth anesthesia, excessive oral secretion and severe continued nausea were observed just after intravenous administration of thiopental 5.3 mg.kg-1. These were overcome by intravenous administration of ketamine 2.0 mg.kg-1. Problems such as difficulty in tracheal intubation and abnormal response to thiopental need special attention in patients complicated with AMC, particularly during induction of anesthesia.
