We report anesthetic experience of two patients suffering from polymyositis. The first case is a 56 year old woman who underwent tympanoplasty for cholesteatoma of the middle ear. Anesthesia was induced with thiopental and deepened with oxygen-nitrous oxide and sevoflurane. ⋯ Concerning the anesthetic management of a patient with polymyositis, there are some informations on the appropriate use of muscle relaxants. It is generally believed that the patient is sensitive to nondepolarizing muscle relaxants and the use of antagonist drug (reversal) may cause muscle weakness, severe dysrhythmia, et al. Therefore we think it is appropriate to manage such a patient without muscle relaxants.

Randomized Controlled Trial Clinical Trial
[Influence of injection speed of the spread of 4.0 ml of 0.5% isobaric bupivacaine in spinal anesthesia].
Influence of injection speed on the spread of isobaric 0.5% bupivacaine 4.0 ml was studied in 100 patients to analyze the correlation between analgesia levels and patient's characteristics. All patients (ASA PS I. II) were scheduled for orthopedic or urological procedures, and received no premedication. ⋯ The maximum sensory block was tested by pinprick method, and no significant difference in the height of sensory block was observed between the two groups. No significant correlation with patient's characteristics was observed except body weight in group 1. This study suggests that the speed of injection does not influence the spread of isobaric 0.5% bupivacaine 4.0 ml.
