To evaluate the effects of unilateral stellate ganglion blockade on left ventricular function. ⋯ In patients without cardiovascular disease, unilateral denervation of the left ventricle after stellate ganglion block produces no clinical deleterious effects on left ventricular function.

Therapeutic selective nerve root block in the nonsurgical treatment of atraumatic cervical spondylotic radicular pain: a retrospective analysis with independent clinical review.
To investigate the outcomes resulting from the use of fluoroscopically guided therapeutic selective nerve root block (SNRB) in the nonsurgical treatment of atraumatic cervical spondylotic radicular pain. ⋯ This study suggests that fluoroscopically guided therapeutic SNRB is a clinically effective intervention in the treatment of atraumatic cervical spondylotic radicular pain.

Randomized Controlled Trial Clinical TrialSedation with sufentanil and midazolam decreases pain in patients undergoing upper limb surgery under multiple nerve block.
Multiple nerve blocks may be painful and a source of discomfort. We assessed the efficacy of sufentanil 5 microg combined with midazolam 1 mg in decreasing pain in outpatients after a midhumeral multiple nerve stimulation technique. Visual analog scores for pain were significantly lower in those patients who received sedation before the block, both at the time of block performance (14 +/- 1 vs 27 +/- 2 mm, P < 0.0001) and at discharge (11 +/- 1 vs 24 +/- 2 mm, P < 0. 0001). We conclude that the association of sufentanil and midazolam produced minimal sedation while significantly reducing pain experienced by patients undergoing multiple nerve stimulation.

Case ReportsTwo instances of central nervous system toxicity in the same patient following repeated ropivacaine-induced brachial plexus block.
We describe two instances of central nervous system (CNS) toxicity in the same patient following repeated brachial plexus blocks induced by high doses of ropivacaine (6 mg x kg(-1) and 4.5 mg x kg(-1), respectively). Although very high total and free plasma concentrations of ropivacaine were found up to 98 min after induction of the blocks, no signs of cardiovascular toxicity apart from hypertension and sinus tachycardia were observed. ⋯ These high doses, however, resulted in severe toxic CNS symptoms. Therefore, it is stressed that the dose in relation to the weight of the patient must be calculated when administering a large volume of local anesthetic.
