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%.

Randomized Controlled Trial Comparative Study Clinical TrialFemoral nerve block with 0.25% or 0.5% bupivacaine improves postoperative analgesia following outpatient arthroscopic anterior cruciate ligament repair.
Femoral nerve block is effective in reducing postoperative pain after inpatient knee surgery. We studied its efficacy compared with standard analgesia following outpatient anterior cruciate ligament repair, including the duration of analgesia and the effect of different concentrations of bupivacaine. ⋯ Femoral nerve block with 0.25% bupivacaine contributes significantly to multimodal postoperative analgesia in the immediate postoperative period following outpatient anterior cruciate ligament repair. Both doses of bupivacaine studied provided analgesia for the first night after surgery.

Randomized Controlled Trial Clinical TrialAnesthetic efficacy of a combination of hyaluronidase and lidocaine with epinephrine in inferior alveolar nerve blocks.
The purpose of this prospective, randomized, double-blind study was to determine the anesthetic efficacy of a buffered lidocaine with epinephrine solution compared to a combination buffered lidocaine with epinephrine plus hyaluronidase solution in inferior alveolar nerve blocks. Thirty subjects randomly received an inferior alveolar nerve block using 1 of the 2 solutions at 2 separate appointments using a repeated-measures design. Mandibular anterior and posterior teeth were blindly pulp tested at 4-minute cycles for 60 minutes postinjection. ⋯ There were no significant differences (P > .05) between the 2 solutions. However, the combination lidocaine/hyaluronidase solution resulted in a significant increase in postoperative pain and trismus. It was concluded that adding hyaluronidase to a buffered lidocaine solution with epinephrine did not statistically increase the incidence of pulpal anesthesia in inferior alveolar nerve blocks and, because of its potential tissue damaging effect, it should not be added to local anesthetic solutions for inferior alveolar nerve blocks.
