Case Reports
Confirmation of internal jugular guide wire position utilizing transesophageal echocardiography.
To describe the utility of transesophageal echocardiography (TEE) in confirmation of correct central line J-wire position. ⋯ The case demonstrates the value of TEE to confirm correct guide wire position prior to insertion of a large bore central venous catheter. TEE visualization of J-wire position avoided repeat attempts at internal jugular cannulation and potential carotid artery puncture.

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
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.
