Comparative StudyComplications of labor analgesia: epidural versus combined spinal epidural techniques.
Both epidural and combined spinal epidural (CSE) analgesia can provide maternal pain relief during labor. Currently, there are few data comparing the risks and complications of these two techniques. We recorded the incidence and severity of anesthetic-related complications in 1022 laboring parturients. ⋯ The other two women had reportedly uncomplicated epidural and CSE analgesia. These data suggest either neuraxial analgesic technique can safely relieve the pain of labor. CSE analgesia is a safe alternative to epidural analgesia for labor and delivery.

Comparative StudyThe partition coefficient as a predictor of local anesthetic potency for spinal anesthesia: evaluation of five local anesthetics in a mouse model.
Local anesthetic partition coefficients correlate with drug potencies in vitro, but in vivo data have not always complimented in vitro results. Despite extensive studies on intrathecal anesthetic action, whether there is correlation between the partition coefficient and local anesthetic potency has not been addressed. Mice (n = 150) were randomly allocated into 15 groups. ⋯ ED50 showed high correlation (R = 0.978) with partition coefficients of local anesthetics. This study implies that the partition coefficient is a predictor of intrathecal local anesthetic potency. We suggest that the mouse model is reliable for evaluation of intrathecal local anesthetic action.
