Comparative Study
A comparison of patient-controlled analgesia and continuous lumbar plexus block after anterior cruciate ligament reconstruction.
Anterior cruciate ligament (ACL) reconstruction is often a painful operation. Fifty-eight patients who underwent ACL reconstruction using patellar tendon autograft received either a lumbar plexus block (LPB) or patient-controlled analgesia (PCA) for pain relief during the first 24 h after surgery. ⋯ The common narcotic analgesic side effects of nausea, pruritus, sedation, and urinary retention were significantly less in the LPB group. The LPB is a safe and effective alternative analgesia after ACL reconstruction.

Median nerve blockade during diagnostic intravenous regional anesthesia as measured by somatosensory evoked potentials.
Intravenous regional anesthesia (IVRA) may be used as a diagnostic method in patients suffering from chronic pain in the forearm or hand to differentiate the origin of pain within the anesthetic area from that above. For this purpose it needs to be proven that all nerve fibers are blocked and that conduction blockade induced by IVRA takes place within the nerve trunks. Therefore the transmission of impulses in a nerve trunk to the central nervous system has been studied. ⋯ The changes in latency and amplitude of SSEPs from the scalp as well as SNAPs and SSEPs from the neck were similar. Because SSEPs, SNAPs, and the pain sensation following median nerve stimulation disappeared during IVRA, it may be concluded that the thick and thin myelinated nerve fibers of the median nerve have been blocked. For diagnostic use, IVRA is superior to peripheral nerve blockade, which has been shown previously to not abolish SSEPs.

Comparative Study[Shoulder surgery using a plexus block: for or against. Against].
Brachial plexus block is an alternative and elegant procedure for shoulder surgery. Three main concerns have to be considered when this technique is planed. ⋯ Thirdly, when nerve lesions of different mechanisms including plexus block itself occur, the origin of the lesion may be difficulty related to its cause. Indications of cervical block are therefore to be considered cautiously when shoulder surgery is performed.
