Randomized Controlled Trial Comparative Study Clinical TrialA comparison of four stimulation patterns in axillary block.
Insufficient spread of the local anesthetic toward the retroarterial region of the neurovascular space may be responsible for inconsistent anesthesia of the upper limb after single-injection axillary block. We hypothesized that injection of the local anesthetic on a single radial-nerve stimulation would produce the same extent of anesthesia as either a single median-nerve stimulation, a double-stimulation technique (radial and musculocutaneous nerves), or a triple-stimulation technique (radial, musculocutaneous, and median nerves). ⋯ Musculocutaneous-nerve stimulation and radial-nerve stimulation play predominant roles in the success of axillary brachial plexus block, although a triple-nerve stimulation technique is still required to produce complete anesthesia of the upper limb.

Plasma concentrations and analgesic effects of ropivacaine 3.75 mg/ml during long-term extrapleural analgesia after thoracotomy.
Fourteen patients received long-term extrapleural analgesia with ropivacaine for postoperative pain relief after posterolateral thoracotomy. We determined plasma concentrations of ropivacaine as well as pain scores and opioid consumption to assess the analgesic effect. ⋯ A dose of 0.375 mg/kg/h of ropivacaine can safely be administered for long-term extrapleural analgesia after thoracotomy.
