Comparative Study
[Analgesic alternatives for the control of postoperatory pain in radical mastectomy].
The purpose of preventive analgesia based on regional blocks with local anesthetics is to avoid sharp and hard-to-control pain in the anterior side of thorax and axilla secondary to radical mastectomy. ⋯ Preventive analgesia by direct transoperational block on nerves turned out to be an effective alternative with low level of systemic morbidity, which must be considered to prevent moderate and severe pain syndromes that are difficult to control in thoracic oncological surgery.

Randomized Controlled Trial Clinical TrialIs a double-injection technique superior to a single injection in posterior subgluteal sciatic nerve block?
Currently, no information is available on the effects of a double-injection technique on onset time and efficacy following subgluteal sciatic nerve blockade. We hypothesized that the success rate and time to onset of subgluteal nerve block following a double-injection technique would be superior to that after a single injection. ⋯ Both the single- and double-injection technique for subgluteal sciatic nerve blockade resulted in acceptable anesthesia in most patients. The double injection generated a faster onset of anesthesia than the single injection. However, the double-injection technique caused more patient discomfort during establishment of the nerve block.

Although clonidine is commonly combined with local anesthetics to extend duration of peripheral nerve block, the mechanism by which clonidine potentiates local anesthetic action in vivo is unclear. ⋯ The findings indicate that prolongation of duration of in vivo lidocaine nerve blockade by clonidine is not mediated by an alpha-adrenergic mechanism but likely involves the Ih current.

Case Reports
Spinal epidural hematoma following central neuraxial blockade and subcutaneous enoxaparin: a case report.
An elderly patient developed a spinal epidural hematoma 3 days after lumbar puncture resulting in paraplegia. Concurrent administration of enoxaparin, aspirin, ketorolac, and a traumatic tap were implicated in causation.
