The purpose of this study was to evaluate the efficacy of combined lumbar plexus block techniques for total knee arthroplasty. Long-acting local anesthetics were used to ensure adequate intraoperative and postoperative anesthesia and analgesia. All patients undergoing total knee arthroplasty at our institution were offered lumbar plexus block after obtaining informed consent. ⋯ There was a 92% overall satisfaction rate with the anesthesia provided by the lumbar plexus block. Lumbar plexus block can be used successfully for total knee arthroplasty. Lumbar plexus block appears to have advantages for early postoperative analgesia, leading to increased patient comfort and satisfaction.

Clinical TrialA single-injection, multi-segmental paravertebral block-extension of somatosensory and sympathetic block in volunteers.
It is our experience that a deposition of an anesthetic solution in the ventral area of the paravertebral space near the parietal pleura and the sympathetic trunk produces extended unilateral block. Because sympathetic block effects in this extended paravertebral block are not reported yet, we undertook this singly blinded, controlled study on the sympathetic change in volunteers. ⋯ One-sided extended analgesia (sensory loss) follows the paravertebral injection of lidocaine. A large ipsilateral sympathetic block is observed without change in pulse rate and with no hypotension. These are all characteristics of an optimal regional block.

Randomized Controlled Trial Clinical Trial[Adiuvants in the axillary brachial plexus blockade. Comparison between clonidine, sufentanil and tramadol].
Evaluated effects of tramadol used as adiuvant in brachial plexus block and compared with clonidine and sufentanil. ⋯ The use of tramadol as adiuvant provides a significative redution of onset time. Also provides a prolongation of anesthesia and analgesia with a quality of block similar that obtained with clonidine and sufentanil and a lower incidence of side effects of clonidine (sedation, bradycardia and hypotension) and sufentanil(itch and sedation). We conclude that tramadol may be a useful alternative, as adiuvant in periferic block, with same effects of other drugs commonly used and a lower incidence of side effects.

Randomized Controlled Trial Clinical Trial
Interscalene brachial plexus anaesthesia with small volumes of ropivacaine 0.75%: effects of the injection technique on the onset time of nerve blockade.
We evaluated the effect of the injection technique on the onset time and efficacy of interscalene brachial plexus anaesthesia. ⋯ We conclude that using a multiple injection technique shortened the preparation time and improved the quality of interscalene brachial plexus anaesthesia performed with small volumes of ropivacaine 0.75%.

Case ReportsAxillary brachial plexus block with patient controlled analgesia for complex regional pain syndrome type I: a case report.
Brachial plexus block (BPB) has been cited as a treatment modality for complex regional pain syndrome type I (CRPS I) of the upper limb. However, there are no reports using axillary BPB with patient controlled analgesia (PCA) for the treatment of CRPS I. This report is based on the retrospective observations of the outcome and effects of axillary BPB with PCA in a patient with CRPS I. ⋯ Axillary BPB with PCA may provide patients with CRPS I of the upper limb a feasible and effective treatment. .
