Randomized Controlled Trial Comparative Study Clinical TrialEffects of intrathecal sufentanil on plasma oxytocin and cortisol concentrations in women during the first stage of labor.
Intrathecal sufentanil provides analgesia comparable to epidural bupivacaine for the first stage of labor. Both epidural local anesthetics and intrathecal opioid reduce some parameters of the neuroendocrine response to labor pain and the reflex release of oxytocin in animals. In humans, epidural local anesthetics only reduce the spurt release of oxytocin. This study compared the effect of intrathecal sufentanil and epidural bupivacaine administration on the plasma concentration of oxytocin and cortisol in women with labor pain during the first stage of labor. ⋯ Intrathecal sufentanil analgesia decreases plasma concentrations of oxytocin and cortisol in women with labor pain during the first stage of labor, but epidural bupivacaine only reduced the cortisol concentration.

Case ReportsPercutaneous radiofrequency lesioning of sensory branches of the obturator and femoral nerves for the treatment of hip joint pain.
The sensory innervation of the hip joint includes the sensory articular branches of the obturator and femoral nerves. In this report, we retrospectively evaluated 14 cases in which hip joint pain was treated by percutaneous radiofrequency lesioning of sensory branches of obturator and/or femoral nerves. ⋯ Percutaneous radiofrequency lesioning of sensory branches of the obturator and femoral nerves is an alternative treatment in patients with hip joint pain, especially in those where operation is not applicable.

Clinical TrialAssessment of QT interval and QT dispersion following stellate ganglion block using computerized measurements.
Prolongation of QT interval and QT dispersion (QTD) may be associated with an increased risk of arrhythmias. This study was designed to investigate the effects of right or left stellate ganglion block (SGB) on RR interval, QT interval, the rate-corrected QT (QTc) interval, QTD and the rate-corrected QTD (QTcD) using computerized measurements. ⋯ Right SGB induces increases of the QT interval, QTc interval, QTD, and QTcD, and left SGB induces decreases of the QT interval and QTc interval.

Clinical TrialVibration sense testing with a 128-Hz tuning fork as a tool to determine recovery from epidural neuraxial block.
Vibration sense testing using a 128-Hz tuning fork is a commonly used test in the diagnosis of dorsal horn dysfunction and polyneuropathy. In this open, prospective study, we tested the hypothesis that vibration sense testing is a sensitive and specific method to assess recovery from epidural block. ⋯ Based on our observations, recovery of vibration sense corresponds with recovery of motor block after epidural anesthesia and may serve as an easy means of documenting recovery with a single test before discharge.
