Randomized Controlled Trial Clinical Trial
[Efficacy of patient-controlled epidural analgesia using a disposable PCA device].
We evaluated efficacy of patient-controlled epidural analgesia (PCEA) using a disposable PCA device (3.0 ml type). Twenty-two patients for elective gynecological surgery were randomized into two groups. Patients of the continuous epidural group received epidural fentanyl (15 micrograms.ml-1) with bupivacaine (1.25 mg.ml-1) from a disposable infusion pump (infusion rate: 2.1 ml.hr-1). ⋯ The incidences of side effects were similar in both groups. Respiratory depression and sedative effects were not observed in both groups. We conclude that PCEA using a disposable PCA device (3.0 ml type) seems to be effective for postoperative pain relief.

Preoperative patients have various kinds of anxiety. However we do not know much about their psychological burden. Therefore, we investigated types of their anxiety with questionnaires prior to operation and analyzed them according to their anesthetic method, type of surgery and age. ⋯ Patients whose age was 10 to 19 had anxiety about their anesthetic method. Anesthesiologists should recognize that preoperative patients have various kinds of anxiety. It is important for us to examine the patients appropriately according to their psychological and physical condition.

The May-Hegglin anomaly is a rare hereditary disorder characterized by the presence of giant platelets and platelet deficiency. This report presents a successful management of a patient with May-Hegglin anomaly. A 5-year-old girl with May-Hegglin anomaly was scheduled for closure of fistulae of her ears. ⋯ Five units of platelet were transfused during the operation. No bleeding tendency was observed perioperatively. It is important to plan the management of anesthesia for a patient with bleeding tendency.

Hoarseness often follows endotracheal intubation. A 58 year old man suffered from hoarseness due to recurrent nerve palsy and submucosal hemorrhage of the right vocal cord after general anesthesia. He was scheduled for resection of chronic pyoderma of the buttocks and atheroma of the right retroauricular region. ⋯ Right recurrent nerve palsy and submucosal hematoma were observed. Without any treatment, hematoma disappeared in 70 days and hoarseness in 183 days. These hematoma and recurrent nerve palsy might be due to the compression of the vocal cord and recurrent nerve by tracheal tube and traction of the recurrent nerve by rotation of the neck.

Case Reports
[Asystole during electroconvulsive therapy in a patient with depression and myasthenia gravis].
A 44-yr-old woman presented with major depression. She was scheduled to receive electroconvulsive therapy under anesthetic care because of drug-induced leukopenia. Her significant past medical history was myasthenia gravis. ⋯ We presented a case of depression for which ECT was applied. Asystole with ECT seems associated with administration of pyridostigmine for the treatment of myasthenia gravis. Pretreatment with atropine can prevent asystole without inducing hazardous tachyarrhythmia.
