Ultrasound imaging used to facilitate performance of a femoral nerve block also affords imaging of adjacent anatomical structures. Following a fracture of the femur, an ultrasound guided femoral nerve block (UGFNB) was performed to provide analgesia; this led to the incidental finding of a previously undiagnosed femoral vein thrombosis (DVT), resulting in a change in patient management before surgery. An inferior vena cava (IVC) filter was placed before intramedullary nailing of the fracture.

Case ReportsContinuous lateral popliteal block with stimulating catheters.
Foot surgery often induces severe postoperative pain. Sciatic nerve block is a good alternative for its treatment. ⋯ Stimulating catheters may be useful to verify correct catheter tip positioning. This technique seem to be easy to use and provided excellent pain relief.

Randomized Controlled Trial Comparative Study Clinical TrialSuprascapular nerve block versus steroid injection for non-specific shoulder pain.
Shoulder pain is a common complaint in elder population and may cause an important functional disability. The aim of this study was to compare the effects of suprascapular nerve block with those of steroid injection in patients with non-specific shoulder pain. A total of 60 patients with shoulder pain lasting for more than four weeks were included in this study. ⋯ No method was found to be superior to each other (p >0.05). No complications occurred in suprascapular nerve block in contrary to steroid injection. We suggest that suprascapular nerve block can be considered the preferred treatment for non-specific shoulder pain because of being as effective as steroid injection with rare side effects.

Motor nerve blockade potency and toxicity of non-racemic bupivacaine in rats.
Racemic [RS(+/-)] bupivacaine can be associated with severe cardiotoxicity. The S(-) isomer is known to be less neuro- and cardiotoxic, but demonstrates a lower potency to block motor activity than RS(+/-) bupivacaine. Thus, the potency and toxicity of a non-racemic bupivacaine mixture were studied. ⋯ The potency of S(-) bupivacaine to block the motor activity in the sciatic nerve was enhanced when 25% of the S(-) isomer was replaced by the antipode R(+) bupivacaine. This effect was not associated with increased toxicity.
