[Marked ST segment elevation in ECG during fiberscope-guided nasotracheal intubation in a patient with tetanus].

: A patient with tetanus showed marked ST segment elevation in ECG during fiberscope-guided nasotracheal intubation. Coronary artery spasm could have been induced probably by tetanospasmin and this would lead to transmural ischemia during procedure. Pretreatment with anti-hypertensive agents such as calcium antagonist as well as sedatives are mandatory even when endotracheal intubation without laryngoscope is scheduled in this disease.
