Randomized Controlled Trial Comparative Study Clinical TrialBrachial plexus block. A comparison of the supraclavicular lateral paravascular and axillary approaches.
Anesthesia of the brachial plexus has been associated with injuries to adjacent structures (e.g., pneumothorax, vascular penetration). It is not uncommon to have only partial block of the upper extremity, hindering completion of the surgical procedure. The supraclavicular lateral paravascular approach to brachial plexus anesthesia has been proposed as an effective, safe alternative to the traditional approaches to brachial plexus anesthesia. ⋯ The supraclavicular lateral paravascular approach is as effective as the axillary approach.

Clinical Trial Controlled Clinical Trial[Mixtures of different local anesthetics for subaxillary plexus anesthesia].
In a prospective clinical study, 76 patients were scheduled for subaxillary plexus block in order to investigate onset time, duration of action and quality of motor and sensitive blockade of various mixtures of local anaesthetics. Sixty-one patients were allocated to four groups. Each of them received 15 ml of bupivacaine 0.5% with either 15 ml of lidocaine 1% (n = 14), of mepivacaine 1% (n = 16), of prilocaine 1% (n = 15) or of etidocaine 1% (n = 15). ⋯ But regarding the quality of motor block, the mixture of bupivacaine and lidocaine was less effective than the other combinations, of which the mixture of bupivacaine and prilocaine showed the best motor block. The combination of the two long-acting local anaesthetics bupivacaine and etidocaine had the longest effect and, therefore, this mixture is a real alternative to subaxillary block via catheter technique. Specific electric stimulation of the radial nerve leads to higher success rate of subaxillary plexus block.

Continuous axillary nerve block was used to relieve pain after a chemical burn to the arm in a child on mechanical ventilation after liver transplantation. The analgesia was sufficient to replace parenteral analgesia and allow extubation.

Superficial cervical block for cervical node biopsy in a child with a large mediastinal mass.
In patients with mediastinal masses, regional anaesthesia may be used for peripheral procedures. We have found the superficial cervical plexus block, when used with midazolam as an amnestic and anxiolytic agent, to be safe, reliable and well-tolerated alternative to general anaesthesia in pediatric patients with mediastinal masses.

MRI and clinical study of an easy and safe technique of suprascapular nerve blockade.
Suprascapular nerve block is used with increasing frequency by anaesthetists and rheumatologists in the management of shoulder pain from a variety of disorders. In the classical technique, the needle is introduced into the supraspinous fossa perpendicular to the blade of the scapula and then is moved to enter the scapular notch, with the risk of pneumothorax or damage to the suprascapular nerve or vessels. ⋯ Introducing the needle parallel to the blade, i.e. away from the direction of the lung and the suprascapular nerve and vessels, and injecting the solution into the floor of the supraspinous fossa is an easy and safe technique. We report the results of a MRI and clinical study that confirm the efficacy of this approach.
