Ultrastructure of canine meninges after repeated epidural injection of S(+)-ketamine.
The safety of ketamine when administered by the spinal route must be confirmed in various animal species before it is approved for use in humans. This study evaluates the ultrastructure of canine meninges after repeated doses of epidural S(+)-ketamine. ⋯ Repeated doses of epidural S(+)-ketamine 5%, 1 mg/kg, twice a day for 10 days was not associated to cellular alterations in canine meninges.

Case ReportsGanglionic local opioid application (GLOA) for treatment of chronic headache and facial pain.
This report describes the effects of ganglionic local opioid application (GLOA) in patients with chronic headache and persistent idiopathic facial pain. ⋯ These results support the theory of sympathetically mediated pain in the head and face, the presence of opioid receptors on the sympathetic ganglia, and a possible beneficial role of opioids in modulation of this process. To our knowledge, this case series is the first case series in the English literature of the use of GLOA at the stellate ganglion for head-and-face pain.

Randomized Controlled Trial Comparative StudyIs there any need for expanding the perineural space before catheter placement in continuous femoral nerve blocks?
There is debate regarding the benefit of perineural space expansion before catheter placement in continuous femoral nerve block. This question is addressed in this prospective, comparative, and randomized study. ⋯ Expansion of the perineural space with D5W is useful for catheter placement in continuous femoral nerve block.

Randomized Controlled TrialEffect of preoperative epidural morphine administration on desflurane requirements during gynecologic surgery.
The goal of this study is to examine the influence of epidural morphine on the end-tidal desflurane concentration titrated to maintain the bispectal index (BIS) values between 40 and 60 during gynecologic surgery. ⋯ Preoperative administration of epidural morphine does not reduce desflurane requirements in patients undergoing gynecologic surgery.

Randomized Controlled TrialNo differences between 20, 30, or 40 mL ropivacaine 0.5% in continuous lateral popliteal sciatic-nerve block.
The aim of this study was to compare the anesthetic and analgesic characteristics of the administration of an initial bolus of 20, 30, or 40 mL of ropivacaine 0.5% through a lateral popliteal sciatic catheter. ⋯ This dose-response study shows that 20 mL of ropivacaine 0.5% injected through an indwelling lateral popliteal catheter is the optimal dose for foot surgery. Higher doses of 30 mL or 40 mL did not provide any further advantage.
