Abstract

BACKGROUND AND OBJECTIVES

Epidural 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.

METHODS

We 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.

RESULTS

Overall, 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.

CONCLUSIONS

Epidural catheters can be reactivated reliably for as long as 24 hours after they are placed.

摘要

背景与目的

在分娩过程中放置用于镇痛的硬膜外导管可在产后用于产后输卵管结扎麻醉。本研究调查了此类硬膜外导管重新激活的成功率。

方法

我们研究了1993年1月至1995年6月期间所有接受硬膜外麻醉分娩且随后硬膜外导管被重新激活以用于产后输卵管结扎（PPTL）手术麻醉的患者。根据分娩与PPTL手术切口之间的间隔时间，将患者分为四组：（a）少于8小时，（b）8小时至少于16小时，（c）16小时至少于24小时，（d）24小时或更长时间。
