To determine the immediate effect of epidural blood patch (EBP) on the hearing loss that can accompany postdural puncture headache (PDPH).
Prospective open study.
Anesthetic and otolaryngologic departments at a university hospital.
16 patients who developed severe PDPH following either myelography or spinal anesthesia.
Epidural injection of 15 ml of autologous blood.
Audiometry at 250, 500, 1,000, 2,000, 4,000, and 8,000 Hz before and one hour after the epidural blood patch was performed. Hearing was significantly improved in 12 of the 16 patients studied. The improvement was at least 10 dB at two or more consecutive frequencies, or 5 dB at four or more consecutive frequencies.
Epidural blood patch improves hearing within one hour in the majority of patients with severe PDPH.
确定硬膜外血贴（EBP）对硬膜穿刺后头痛（PDPH）伴发的听力损失的即时影响。
前瞻性开放研究。
大学医院的麻醉科和耳鼻喉科。
16例在脊髓造影或脊髓麻醉后发生严重PDPH的患者。
硬膜外注射15毫升自体血。
在进行硬膜外血贴之前及之后1小时，分别对250、500、1000、2000、4000和8000赫兹频率进行听力测定。在研究的16例患者中，有12例听力显著改善。改善情况为在两个或更多连续频率至少提高10分贝，或在四个或更多连续频率至少提高5分贝。
对于大多数严重PDPH患者，硬膜外血贴可在1小时内改善听力。
