Abstract

Dermatomyositis is an idiopathic inflammatory myopathy characterized by skin changes and muscle weakness. Depending on the involvement of various muscles, dermatomyositis can cause aspiration pneumonia, ventilatory impairment, and heart failure. Several reports have documented normal or prolonged neuromuscular blockade following administration of different non-depolarizing neuromuscular blockers in patients with dermatomyositis. We observed delayed onset of blockade and prolonged recovery following administration of 0.6 mg/kg rocuronium in a patient with dermatomyositis. However, when the train-of-four ratio reached 0.3, the patient was administered pyridostigmine and glycopyrrolate, which led to normal response to reversal of rocuronium. The patient was extubated without respiratory complications. The outcomes of this case indicate that response to the usual dosage of muscle relaxants in patients with dermatomyositis might be different from that in patients without this condition. Anesthesiologists should pay attention to preoperative cardiorespiratory evaluation and intraoperative neuromuscular monitoring.
