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 ReportsAn unusual case of painful phantom-limb sensations during regional anesthesia.
The objective of this article is to describe a late-onset phantom-limb pain during a continuous analgesic popliteal nerve block after foot surgery and its alleviation and recurrence when stopping and resuming the local anesthetic infusion. ⋯ This observation suggests that phantom-limb pain can be of late-onset and might occur during a continuous infusion of low-concentration local anesthetic responsible only for an analgesic block, as shown by the fact that only thermal and pinprick sensations, known to depend on Adelta-fibers and C-fibers, were altered. Therefore, this case contradicts the usual belief that a profound block is necessary to elicit phantom-limb pain.

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.

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.
