Curriculum and cases for pain medicine crisis resource management education.
Medical crises that may occur in the setting of a pain medicine service are rare events that require skillful action and teamwork to ensure safe patient outcome. A simulated environment is an ideal venue for both acquisition and reinforcement of this knowledge and skill set. Here, we present an educational curriculum in pain medicine crisis resource management for both pain medicine fellows and attending physicians as well as the results of a successful pilot program.

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.

The involvement of potassium channels in the peripheral antiedematogenic effect of intrathecally injected morphine in rats.
A previous study indicated that intrathecal administration of morphine reduces experimental inflammatory edema in rats by activating the nitric oxide/cyclic guanosine monophosphate pathway. This evidence supports the hypothesis that potassium channel opening may play an important role in mediating morphine's effect under such conditions. ⋯ These results support the hypothesis that the peripheral antiedematogenic effect produced by intrathecal morphine is mediated by potassium channel activation. Furthermore, this opioid effect does not involve the inhibition of acute neutrophil migration but does involve a reduction in capillary recruitment.
