Randomized Controlled Trial Comparative Study Clinical Trial
Effect of neurolytic celiac plexus block on pain relief, quality of life, and survival in patients with unresectable pancreatic cancer: a randomized controlled trial.
Pancreatic cancer is an aggressive tumor associated with high mortality. Optimal pain control may improve quality of life (QOL) for these patients. ⋯ Although NCPB improves pain relief in patients with pancreatic cancer vs optimized systemic analgesic therapy alone, it does not affect QOL or survival.

Randomized Controlled Trial Clinical Trial
Clonidine added to bupivacaine enhances and prolongs analgesia after brachial plexus block via a local mechanism in healthy volunteers.
The addition of clonidine to local anaesthetics enhances pain relief after peripheral nerve block, but the site of action is unproven. ⋯ The admixture of clonidine to bupivacaine plus epinephrine prolongs and enhances brachial plexus blockade. Lower clonidine plasma concentrations for block treatment strongly suggest a local effect.

Ultrasound is a novel method of nerve localization but its use for lower extremity blocks appears limited with only reports for femoral 3-in-1 blocks. We report a case series of popliteal sciatic nerve blocks using ultrasound guidance to illustrate the clinical usefulness of this technology. ⋯ Our preliminary experience suggests that ultrasound localization of the sciatic nerve in the popliteal fossa is a simple and reliable procedure. It helps guide block needle placement and assess local anesthetic spread pattern at the time of injection.

Diaphragmatic excursion and respiratory function after the modified Raj technique of the infraclavicular plexus block.
The effects of the infraclavicular plexus block using the modified Raj approach on diaphragm and respiratory function have not been investigated. ⋯ Infraclavicular block using the modified Raj technique did not interfere with diaphragmatic excursion or respiratory function.

Case Reports
Fatal streptococcal necrotizing fasciitis as a complication of axillary brachial plexus block.
A 74-yr-old diabetic woman developed necrotizing fasciitis of the right upper limb after axillary brachial plexus block for carpal tunnel decompression. Clinical signs included oedema, diffuse swelling and bullae; rapidly followed by toxic shock syndrome and multiorgan failure. ⋯ Delay in antibiotic and surgical treatment probably affected the outcome. Early diagnosis and treatment are essential to improve the outcome of streptococcal necrotizing fasciitis.
