Dose-Response Curves for Intrathecal Bupivacaine, Levobupivacaine, and Ropivacaine Given for Labor Analgesia in Nulliparous Women
Bupivacaine, levobupivacaine, and ropivacaine are often given intrathecally for labor analgesia, but limited data are available for their dose-response properties in this context. The objective of this study was to describe the dose-response curves of these local anesthetics when given intrathecally for labor analgesia, to determine values for D50 (dose producing a 50% response) and to compare the calculated values of D50 for levobupivacaine and ropivacaine with those for bupivacaine
