Epidural blood patch is a standard treatment for obstetric patients experiencing a severe post-dural puncture headache. Patients who sustained an accidental dural puncture during establishment of epidural analgesia during labour or at caesarean delivery were randomly assigned to receive a prophylactic epidural blood patch or conservative treatment with a therapeutic epidural blood patch if required. Eleven of 60 (18.3%) patients in the prophylactic epidural blood patch group developed a post-dural puncture headache compared with 39 of 49 (79.6%) in the therapeutic epidural blood patch group (p < 0.0001). A blood patch was performed in 36 (73.4%) of patients in the therapeutic group. The number of patients who needed a second blood patch did not differ significantly between the two groups: 6 (10.0%) for prophylactic epidural blood patch and 4 (11.1%) for therapeutic epidural blood patch. We conclude that prophylactic epidural blood patch is an effective method to reduce the development of post-dural puncture headache in obstetric patients.
硬膜外血补丁治疗是产妇硬脊膜穿刺后严重头疼的标准治疗方法,本研究纳入分娩镇痛或剖宫产时硬膜外意外穿刺的患者,随机接受预防性硬膜外血补丁治疗或仅在需要时行血补丁治疗。预防组的头疼发生率为11/60(18.3%);而治疗组为39/49(79.6%),有明显差异。治疗组血补丁为73.4%。两组间需要再次血补丁治疗的患者数无统计学意义。
结论认为,预防性血补丁治疗可有效预防产科患者硬脊膜意外穿刺后头疼的发生。
