Case ReportsSuspected malignant hyperthermia during isoflurane anesthesia--a case report.
We present a patient with thyroid cancer, who developed respiratory acidosis, tachycardia and hyperthermia during isoflurane anesthesia. Malignant hyperthermia was suspected on the basis of clinical manifestation and laboratory finding. With early diagnosis and treatment the patient survived the episode.

Case ReportsManipulation of epidural catheter that has migrated restores adequate postoperative analgesia--a case report.
The use of epidural anesthesia and analgesia is ordinary in patients undergoing total knee replacement (TKR). As many as 23% of epidural anesthetics may not provide satisfactory analgesia for women in labor. ⋯ We reported a case in whom the in-place epidural catheter which functioned well for surgical anesthesia previously migrated to an intervertebral foramen postoperatively and led to failure of providing post-operative analgesia. With deliberate manipulation we succeeded in restoring its function and analgesia showed up again.

Case ReportsVentricular tachycardia after oxytocin injection in patients with prolonged Q-T interval syndrome--report of two cases.
Oxytocin is widely used in obstetric settings to stimulate uterine contraction and prevent postpartum hemorrhage. Its adverse effects which include transient hypotension and increase heart rate could be life-threatening in patients with fixed cardiac output or hypotension resulting from hemorrhage. We reported two cases suspected to have preexisting prolonged Q-T interval syndrome (PQTS) who developed ventricular tachycardia immediately after intravenous injection of oxytocin. Anesthetic management of and use of oxytocic agents in patients with PQTS were discussed.
