Review Case Reports
Grand mal convulsion and plasma concentrations after intravascular injection of ropivacaine for axillary brachial plexus blockade.
We report a patient to whom ropivacaine 1.1 mg kg(-1) was administered for brachial plexus blockade and who developed grand mal convulsions because of inadvertent i.v. injection. No symptoms of cardiovascular toxicity occurred. ⋯ The measured total plasma concentrations of ropivacaine were 3.3, 1.6, 1.2 and 1.0 mg litre(-1) respectively. Initial plasma concentration after the end of the injection period was estimated at 5.75 mg litre(-1) using a two-compartment pharmacokinetic model.

Comparative StudyA comparative study of general anesthesia, intravenous regional anesthesia, and axillary block for outpatient hand surgery: clinical outcome and cost analysis.
IV regional anesthesia can offer a more favorable patient recovery profile and shorter postoperative nursing care time and hospital discharge time than an isoflurane-based general anesthetic or brachial plexus block technique for hand surgery.

Randomized Controlled Trial Clinical TrialA paravenous approach for the saphenous nerve block.
This study assesses a paravenous approach for saphenous nerve block at approximately the level of the tibial tuberosity, and compares it with the conventional technique of blind subcutaneous infiltration between the tibial tuberosity and the gastrocnemius muscle. ⋯ The saphenous nerve can be blocked effectively by a paravenous approach using only 5 mL of local anesthetic solution. This approach is advantageous because of its easily identifiable landmark.
