Background And ObjectivesEpidural catheters placed for analgesia during labor and delivery can be reused in the postpartum period for postpartum tubal ligation anesthesia. This study examined the success rate of such reactivation of epidural catheters.MethodsWe studied all patients who had received an epidural anesthetic for labor and delivery and who had the epidural catheter reactivated at a later time to provide anesthesia for a postpartum tubal ligation (PPTL) procedure between January, 1993 and June, 1995. The patients were divided into four groups based on the interval between delivery and PPTL incision: (a) less than 8 hours, (b) 8 hours to less than 16 hours, (c) 16 hours to less than 24 hours and (d) 24 hours or more.ResultsOverall, 92% (129/140) of the patients had their epidural catheters successfully reactivated. The success rate in all but the last group was over 90%, while only 80% of catheters could be reactivated if left in place for more than 24 hours.ConclusionsEpidural catheters can be reactivated reliably for as long as 24 hours after they are placed.
