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.

Randomized Controlled Trial Comparative Study Clinical TrialSciatic nerve block. A comparison of single versus double injection technique.
Two techniques, single versus double injection, for blocking the sciatic nerve via the classical (Labat) approach were prospectively evaluated for onset and efficacy of block in 50 adult patients undergoing lower extremity surgery. The tibial, common peroneal, and posterior femoral cutaneous nerves were evaluated at 5, 10, 15, 20, 30, and 45 minutes after the initial injection of local anesthetic. Motor function was used to assess the block of the tibial and common peroneal nerves while pinprick response was used to assess block of the posterior femoral cutaneous nerve. ⋯ The double injection technique for sciatic nerve block via the classical approach results in a more rapid onset and increased efficacy of block than that of the single injection technique.

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.

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.

Incidence and clinical significance of hemidiaphragmatic paresis in patients undergoing carotid endarterectomy during cervical plexus block anesthesia.
This study was designed to investigate the incidence and clinical consequences of hemidiaphragmatic paresis in patients undergoing carotid endarterectomy using cervical plexus block anesthesia. In 28 patients, diaphragmatic motion was evaluated by fluoroscopy 20 min after cervical plexus block with 1% mepivacaine. ⋯ These motion anomalies were associated with a statistically significant elevation of PaCO2. Gender, age, and whether the block was on the left or right side did not appear to affect the incidence of motion abnormalities after cervical plexus block anesthesia.
