General anesthesia was given to six surgical patients with hypertrophic cardiomyopathy on eight occasions from 1990 to 1992. Anesthetic courses were uneventful in five patients diagnosed previously as hypertrophic cardiomyopathy. ⋯ A slight hypotension caused by epidural anesthesia had a devastating effect on the patient. The above experiences stress the importance of early diagnosis and careful observation in perioperative period.

We report a case of intracranial subdural hematoma following spinal anesthesia in a 28-year-old woman. Subdural hematoma is a very rare, but life-threatening complication. When a patient complains of persistent post spinal headache, one should consider the possibility of subdural hematoma and carry out a careful examination, including MRI or CT scan.

A case of severe supine hypotensive syndrome in a parturient associated with breech presentation was presented. It is suggested that failure of left tilt to prevent the hypotension was associated with anatomical displacement of the uterus to the right. The importance of trying right tilt, if response to left tilt is poor, is emphasized.

Recently we reported a case of inadvertent migration of an epidural catheter into the endothoracic fascia. Anesthetic injection into the fascia brought a broad unilateral analgesia. To clarify the mechanism of anesthesia. ⋯ The crimson dye, the substitute of the anesthetic agent, reached the transversial fascia in the abdominal cavity through medial and lateral arcuate ligament. Subcostal nerve, iliohypogastric nerve, ilioinguinal nerve, genitofemoral nerve and lateral femoral cutaneous nerve were found to be in the course of dye dispersion. The renal adiposal fascia plays a role of a reservoir for the anesthetic agent and prevents the further anesthetic dispersion.

Clinical Trial Controlled Clinical Trial
[Evaluation of midazolam premedication for preoperative anxiolysis].
To evaluate the anxiolysis property of midazolam, 60 patients undergoing minor gynecological surgery were given midazolam 0 mg (n = 20), 2.5 mg (n = 20) or 4 mg (n = 20) intramuscularly as premedication 1 h before their entrance to operating theater. The degree of anxiety was evaluated objectively using the State-Trait Anxiety Inventory (STAI). ⋯ In only midazolam 4 mg group, anxiety was reduced significantly in the operating room compared to the day before operation. It is concluded that midazolam (4 mg) is suitable to reduce the preoperative anxiety in patients who are to undergo minor gynecological surgery.
