[Tracheal intubation in a case of idiopathic pulmonary fibrosis using remifentanil and propofol without muscle relaxants].

The anesthetic management of a 58 year-old-male suffering from idiopathic pulmonary fibrosis associated with a previous experience of altered dose-response relationship to muscle relaxants is reported. He underwent a gastroendoscopic surgical procedure. After intravenous atropine, remifentanil 3.0 microg kg(-1) was injected over 90 sec. Sixty seconds after the start of remifentanil bolus dose, propofol 2.0 mg kg(-1) was injected and intubation was performed 1 min after the administration of propofol. Anesthesia was maintained by N(2)O, oxygen, sevoflurane (0.5-0.8%) and remifentanil titrated infusion (mean dose of 0.15 mg kg(-1) min(-1)) under spontaneous respiration or assisted ventilation, if the patient was apnoic. The intubating conditions were good, a 30 per cent reduction in MAP was observed after propofol administration. The patient regained consciousness 5 minutes after the end of remifentanil administration and his trachea was extubated without any troubles. Recovery was uneventful without the need of long-term intensive therapy.
