Our Anesthesia Experience for Lower Extremity Surgery in a Patient with Polymyositis

Polymyositis is one of the subtypes of idiopathic inflammatory myopathies characterized by progressive muscle weakness. Several pulmonary and cardiac manifestations such as interstitial lung disease, pulmonary dysfunction due to weakness of thoracic muscles, arrhythmias, dilated cardiomyopathy, and low ejection fraction can be accompanied this disease. The major concerns in the anaesthetic management of the patients with PM are the presence of various systemic disorders such as aspiration pneumonia, interstitial lung disease, cardiac arrhythmia, myocarditis and heart failure, and the potential risks of the use of muscle relaxant agent. Therefore, the anaesthetic management of these patients requires more attention and close monitoring. As in our case, laryngeal mask airway placement without using any muscle relaxant can be safely preferred in selected cases
