We report a patient who was given continuous epidural anesthesia due to painful contractions during delivery of a child after intrauterine fetal death. Placement of the catheter and repeated reinjections were carried out without problems, however, during withdrawal of the catheter it could only be pulled 1-2 cm until there was enormous resistance. An X-ray film showed knotting of the catheter in the epidural space. Firm pulling finally allowed complete withdrawal of the catheter. Insertion of the catheter too far into the epidural space initially must be considered as a possible cause. As this complication rarely occurs, we consider this case worth reporting.
我们报告了一名患者，其在胎儿宫内死亡后分娩时因宫缩疼痛接受了连续硬膜外麻醉。导管置入及多次重复注射均顺利，但在拔出导管时，仅能拔出1 - 2厘米便遇到极大阻力。X线片显示导管在硬膜外间隙打结。用力牵拉最终使导管完全拔出。最初导管插入硬膜外间隙过深必须被视为可能的原因。由于这种并发症很少发生，我们认为此病例值得报告。
