Infraclavicular brachial plexus block effects on respiratory function and extent of the block.
Axillary block is devoid of severe respiratory complications. However, incomplete anesthesia of the upper limb is the main disadvantage of the technique. Theoretically, the more proximal infraclavicular approach would produce a more extensive block without the risk of pneumothorax. However, neither its effects on respiratory function nor a detailed characterization of the extent of neural block has been assessed. The goal of this study was to evaluate the possible changes in respiratory function and also the extent of the block after infraclavicular block. ⋯ Infraclavicular block does not produce a reduction in respiratory function.

Injection of the piriformis muscle by fluoroscopic and electromyographic guidance.
There is not a universally accepted single technique for injection of the piriformis muscle that has validated exact placement of the needle tip within the piriformis muscle. ⋯ Using this methodology, injections on 17 occasions in 11 patients resulted in needle placement within the piriformis muscle.

Randomized Controlled Trial Clinical TrialThe safety and efficacy of intrabursal oxycodone and bupivacaine in analgesia after shoulder surgery.
Peripherally administered opioids, e.g., intra-articular morphine, exert their analgesic action on local opioid receptors. The present study investigated the safety and efficacy of intrabursal oxycodone and bupivacaine in comparison with bupivacaine infiltration and interscalene brachial plexus block in conjunction with shoulder surgery. ⋯ According to the present study, intrabursal oxycodone and bupivacaine offer an acceptable and efficient method for postoperative analgesia after shoulder surgery.

Case ReportsRepeated episodes of transient radiating back and leg pain following spinal anesthesia with 1.5% mepivacaine and 2% lidocaine.
Transient radiating back and leg pain defined as pain or dysesthesias in the buttocks, thighs, or calves within 24 to 48 hours after recovery from spinal anesthesia has been described with the use of 2% and 5% lidocaine. These symptoms have also been associated with other local anesthetics such as bupivacaine and tetracaine, although with a much lower incidence. A recent case report and prospective study have described transient radiating back and leg pain occurring following spinal anesthesia with 4% mepivacaine. ⋯ Transient radiating back and leg pain may occur with lower concentrations (1.5%) of mepivacaine, as it does with lidocaine. The relationship between transient radiating back and leg pain and spinal stenosis is also discussed.

Clinical TrialThe influence of the menstrual cycle in postdural puncture headache.
We performed a preliminary study to analyze the influence of the menstrual cycle on the incidence of postdural puncture headache (PDPH). ⋯ According to our results, the menstrual cycle and hormonal levels may not have any influence on the appearance of PDPH in female patients, although a larger series is required to validate these results.
