Case Reports
[Spinal anesthesia with bupivacaine for a patient with a history of severe leg pain after intrathecal dibucaine].
An 87-year-old man was scheduled for the 11th transurethral bladder tumor resection (TURBT). He had a history of non-active syphilis for 21 years, diabetes mellitus for 7 years, and severe emphysema. Preoperative physical examination of the lower extremities, revealed loss of knee-jerk reflex, and loss of vibratory and proprioceptive perception. ⋯ Therefore we planned spinal anesthesia using 0.5% bupivacaine, 2.0 ml. This time, he did not complain of leg pain during anesthesia, and postoperative conditions were satisfactory. We can conclude that bupivacaine is very useful for spinal anesthesia especially in patients with a history of leg pain by spinal anesthesia with dibucaine.

Case Reports
[Successful intravenous administration of low dose ketamine for pain caused by erythromelalgia: report of a case].
A 15-year-old female complained of reddening, edema, and pain in her hands and feet. The symptoms were relieved upon cooling. ⋯ A low dose of ketamine, a drug considered to be effective for intractable pain, was administered intravenously and the pain subsided significantly. Furthermore, the pain became completely controllable with a combination of intramuscular ketamine injection and other oral medication.

We evaluated the effect of olprinone hydrochloride on intraocular pressure (IOP) and ocular blood flow in patients after cardiac surgery under cardiopulmonary bypass (CPB). ⋯ We demonstrated that olprinone hydrochloride led to a decrease in IOP and an increase in ocular blood flow in patients after cardiac surgery under CPB.

The aim of this study is to examine the duration and magnitude of vasodilating effect induced by sympathetic block with the addition of different concentrations of clonidine to mepivacaine. ⋯ Sympathetic block with the addition of clonidine to local anesthetics increases both duration and magnitude of its vasodilating effect. However, sympathetic block with the addition of higher doses of clonidine to local anesthetics may induce shorter duration and lower magnitude of vasodilating effect compared with local anesthetics alone.

Randomized Controlled Trial Comparative Study Clinical Trial
[Comparison of zopiclone and midazolam premedication for preoperative anxiolysis].
To compare the anxiolysis property of zopiclone (ZPC) and midazolam (MDZ), 117 patients were given zopiclone 7.5 mg p.o. or midazolam 0.05 mg.kg-1 i.m. as premedication. In the study 1, patients were randomly allocated to 4 groups: ZZ group (n = 16) received ZPC in the night before operation and 2 h before operation, ZM group (n = 18) received ZPC in the night before operation and MDZ 1 h before operation, Z group (n = 18) received ZPC 2 h before operation, and M group (n = 24) received MDZ 1 h before operation. The degree of anxiety was evaluated using the state-trait anxiety inventory (STAI) on the day before operation and after receiving premedication. ⋯ The degree of anxiety was evaluated using the visual analog scale (VAS) on the day before operation and after receiving premedication. ZPC showed a significant reduction in the VAS score, but MDZ showed no changes in the VAS. It is concluded that ZPC (7.5 mg p.o.) is suitable to reduce the preoperative anxiety in patients who are to undergo surgery as compared to MDZ (0.05 mg.kg-1 i.m.).
