Randomized Controlled Trial Clinical TrialInterscalene brachial plexus anesthesia with ropivacaine 5 mg/mL and bupivacaine 5 mg/mL: effects on electrocardiogram.
Cardiotoxicity is the most severe complication of long-acting local anesthetics. The aim of this trial is to compare early signs of depression of cardiac conduction linked with the administration of either ropivacaine or bupivacaine for interscalene block. ⋯ Electrocardiographic recordings were similar in both groups, except for a significant prolongation of the PQ interval in the bupivacaine group at plasma levels below threshold for cardiotoxicity.

Randomized Controlled Trial Comparative Study Clinical TrialA single injection ultrasound-assisted femoral nerve block provides side effect-sparing analgesia when compared with intrathecal morphine in patients undergoing total knee arthroplasty.
Postoperative pain after total knee arthroplasty (TKA) is severe, and achieving adequate analgesia remains a clinical challenge. We tested the hypothesis that, in patients having unilateral TKA under intrathecal (IT) anesthesia, the addition of a femoral nerve block would provide superior analgesia when compared with IT morphine and demonstrate fewer adverse side effects. In a single-blinded and controlled trial, 41 ASA I-III patients undergoing unilateral TKA were randomized into 2 groups. ⋯ However, group FNB had fewer perioperative side effects including nausea, vomiting, and pruritus (P < 0.05 for each event). This corresponded to a decrease in patient satisfaction in group ITM, in which 20% of the patients rated their experience as "unsatisfactory" (P < 0.05). We conclude that, in comparison with IT morphine, a single injection femoral nerve block provides equivalent analgesia but with a significant reduction in side effects for patients having TKA under bupivacaine intrathecal anesthesia.

Comparative Study Clinical TrialPrilocaine or mepivacaine for combined sciatic-femoral nerve block in patients receiving elective knee arthroscopy.
The aim of this study was to evaluate the onset time of surgical block, recovery of motor function and duration of post-operative analgesia of combined sciatic-femoral nerve block performed with either mepivacaine or prilocaine. ⋯ Prilocaine 1% provides adequate sensory and motor block for arthroscopic knee surgery, with a clinical profile similar to that produced by 2% mepivacaine, and may be a good option for surgical procedures of intermediate duration and not associated with severe postoperative pain.
