BACKGROUND Microparticulate local anesthetics-loaded delivery systems are known to provide a controlled release of drug and to reduce systemic toxicity resulting from transient high plasma concentrations. The aim of this study was to evaluate epidural, intrathecal and plasma pharmacokinetics of ropivacaine following epidural administrations of repeated(More)
BACKGROUND Ropivacaine is used by the epidural route for postoperative pain management with various neuraxial techniques. Given the widespread use of these techniques and the relative paucity of data on spinal disposition of local anesthetics, we evaluated through an experimental animal model, the spinal disposition of ropivacaine, allowing further studies(More)
BACKGROUND AND OBJECTIVES Neural blockade techniques are associated with a risk of acute cardiac toxicity after accidental intravenous (IV) injection of local anesthetics. The aim of this study was to compare electrocardiographic (ECG) and hemodynamic (HEM) effects induced by IV infusion of local anesthetics in an anesthetized ewe model. METHODS(More)
Background and Objectives: Neural blockade techniques are associated with a risk of acute cardiac toxicity after accidental intravenous (IV) injection of local anesthetics (LAs). The aim of this study was to compare electrocardiographic (ECG) and hemodynamic (HEM) effects induced by IV infusion of LAs in an anesthetized ewe model. Methods: Thirty-two(More)
BACKGROUND Amitriptyline (AMI) is a lipophilic, tricyclic antidepressant with analgesic properties that could potentially be used for epidural (EPI) analgesia. However, no pharmacokinetic data are available for AMI in spinal spaces. The objective of this study was to evaluate the spinal disposition and intrathecal (IT) bioavailability of AMI after IT and(More)
