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.

Case ReportsDelayed severe airway obstruction due to hematoma following stellate ganglion block.
Delayed onset of airway obstruction following stellate ganglion block (SGB) may be life threatening. We treated a patient who developed a severe airway obstruction caused by a large hematoma several hours after an SGB. ⋯ We believe that the SGB needle injured the vertebral artery and caused massive hemorrhage anterior to the cervical vertebra, subsequently inducing pharyngolaryngeal edema by obstructing the venous and lymphatic drainage of the cervical region.

Randomized Controlled Trial Meta Analysis Comparative Study Clinical TrialRegional anesthesia does not significantly change surgical time versus general anesthesia--a meta-analysis of randomized studies.
The major determinant of variable operating room costs is surgical time. A number of factors contribute to surgical time. This study was designed to determine whether regional anesthesia decreases surgical time when compared with general anesthesia over several surgical procedures. ⋯ Overall, the use of regional anesthesia does not significantly decrease surgical time.
