Randomized Controlled Trial Clinical Trial
Preoperative diclofenac is a useful adjunct to spinal anesthesia for day-case varicose vein repair.
To examine if preoperative diclofenac 50 mg or diazepam 10 mg po are useful adjuncts to spinal anesthesia for day-case varicose vein repair. ⋯ Diclofenac premedication reduced the analgesic requirements during the first eight hours after varicose vein repair.

Case Reports
Combined spinal-epidural anesthesia for Cesarean section in a patient with peripartum dilated cardiomyopathy.
To report a case of peripartum dilated cardiomyopathy associated with morbid obesity and possible difficult airway presenting for elective Cesarean section, which was successfully managed with combined spinal-epidural anesthesia. ⋯ In patients suffering from peripartum cardiomyopathy, undergoing Cesarean section, combined spinal-epidural anesthesia may be an acceptable anesthetic alternative.

To investigate the effect of xenon (Xe) and nitrous oxide (N(2)O) on norepinephrinergic neuronal activity in the rat medial preoptic area (mPOA) and posterior hypothalamus (PH) using microdialysis. ⋯ The present data suggest that Xe stimulates norepinephrinergic neurons more potently than N(2)O; 1.2 times more in the mPOA and 2.5 times more in the PH. This stimulant effect may contribute to the hypnotic and sympathotonic effects of Xe in rats.

Randomized Controlled Trial Clinical Trial
Low dose intrathecal ropivacaine with or without sufentanil provides effective analgesia and does not impair motor strength during labour: a pilot study.
Although ropivacaine has been used to provide spinal anesthesia in the surgical population, its intrathecal administration for labour analgesia has only recently been described. We evaluated the effects of low dose intrathecal ropivacaine with or without sufentanil for labour analgesia. ⋯ Low dose ropivacaine provides effective analgesia during labour via the intrathecal route. It can be mixed with sufentanil in the above-mentioned concentrations to improve both the quality and duration of analgesia. Fetal outcome remains favourable. It may provide minimal or no motor block, to facilitate ambulation.
