An epidural anesthetic was planned for a 24-year-old woman for analgesia during labor and for a 28-year-old woman for an elective cesarean delivery.
Two cases of inability to remove an epidural catheter due to a knot are reported. The epidural catheter was initially inserted 6 and 8 cm, respectively, into the epidural space. Attempts to remove the catheter by gentle traction remained unsuccessful.
In the first case, the catheter was removed successfully by using general anesthesia with succinylcholine, and in the second case the catheter was removed by pulling it out slowly.
To prevent the knotting of an epidural catheter, it should not be inserted more than 3-4 cm into the epidural space. General anesthesia may be one of the options to remove the catheter.
计划为一名24岁女性在分娩期间实施硬膜外麻醉以镇痛，为一名28岁女性实施择期剖宫产手术麻醉。
报告两例因打结而无法拔除硬膜外导管的病例。硬膜外导管最初分别插入硬膜外间隙6厘米和8厘米。通过轻柔牵引试图拔除导管均未成功。
第一例中，使用琥珀酰胆碱全身麻醉成功拔除导管；第二例中，通过缓慢拔出导管将其移除。
为防止硬膜外导管打结，其插入硬膜外间隙的深度不应超过3 - 4厘米。全身麻醉可能是拔除导管的选择之一。
