Abstract:The cardiotoxic effects of bupivacaine, a widely used local anesthetic, may be age-dependent because neonates and children tolerate a higher plasma concentration of bupivacaine after intravenous administration than adults. No studies have compared the toxicity profiles of the bupivacaine isomers in human neonates and children, but differences in the lethal dose have been observed between adult and younger rats. Here, we determined the age dependency of cardiac toxicity induced by racemic RS(±) bupivacaine and … Show more
