Randomized Controlled TrialEfficacy of intrathecal baclofen on different pain qualities in complex regional pain syndrome.
Complex regional pain syndrome (CRPS) is characterized by severe debilitating chronic pain. Patients with CRPS may experience various pain sensations, which likely embody different pathophysiologic mechanisms. In this study, we evaluated the differential effects of central γ-aminobutyric acid (B) receptor stimulation on the different pain qualities in CRPS patients with dystonia. ⋯ γ-Aminobutyric acid (B) receptor stimulation by ITB exerts differential antinociceptive effects on specific pain qualities in CRPS patients with dystonia.

Estimate of the relative risk of succinylcholine for triggering malignant hyperthermia.
Facilities with volatile anesthetic agents stock dantrolene for the treatment of malignant hyperthermia (MH). The availability of dantrolene at these facilities satisfies cost-utility norms even for sites with as few as 1 anesthetic per workday, based on the overall incidence of MH per anesthetic. We considered the stocking of dantrolene at facilities with succinylcholine alone (i.e., where volatile anesthetics are not available), by using registry data and estimates of the frequency of administration of succinylcholine during anesthesia. We determine the magnitude of the relative risk of the administration of succinylcholine for triggering MH. ⋯ Our results provide no insight into the triggering mechanism for MH (i.e., succinylcholine could in isolation have an extremely low incidence of inducing MH, yet markedly increase the risk when administered in combination with volatile anesthetics). Until more epidemiologic data are collected and analyzed, having dantrolene available, where succinylcholine may be used, is reasonable, and this practice should be maintained.

Review Meta Analysis Comparative StudyIntermittent epidural bolus compared with continuous epidural infusions for labor analgesia: a systematic review and meta-analysis.
Intermittent epidural bolus when compared with continuous epidural infusion for labour analgesia results in slightly reduced local anaesthetic use and a small improvement in maternal satisfaction. Caesarean section and instrumental delivery rates were not significantly statistically different.
