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.

Lumbar plexus block is indicated in anesthesia and analgesia of the proximal part of the lower limb. Several techniques, two via the anterior approach and at least three via a posterior paravertebral approach have been described. All these techniques are not equivalent in terms of technical facilities or difficulties, efficacy, success or failure rates and postoperative analgesia. The best choice must be done keeping in mind all advantages or disadvantages of each technic.

Randomized Controlled Trial Clinical TrialWarm local anaesthetic--effect on latency of onset of axillary brachial plexus block.
A double-blind, controlled trial was conducted to determine whether warming local anaesthetic reduces the onset time of axillary brachial plexus block. Forty patients were randomised into two groups. ⋯ A solution of 40 ml of lignocaine 1.5% with adrenaline 1:200,000 was used for all patients. Warming the local anaesthetic was not demonstrated to reduce the latency of onset of blockade.
