To determine whether leaving an intrathecal catheter in place in the postoperative period prevents postdural puncture headache (PDPH).
Lumbar puncture was performed with an 18-gauge Tuohy needle. 0.5% bupivacaine spinal anesthesia was given through a 20-gauge catheter in 87 patients having orthopedic surgery. Postoperatively, patients were allocated randomly to have the catheter immediately withdrawn (group 1, N = 47) or kept in place for 12 to 24 hours (group 2, N = 40). Patients were questioned by a blinded observer, about PDPH twice a day on postoperative days 1, 2, 3, and 8.
The incidence of PDPH was 9.2%, and this was comparable in the two groups (5 patients in group 1 and 3 patients in group 2).
Leaving the intrathecal catheter in place in the postoperative period for 12 to 24 hours does not prevent PDPH.
确定术后保留鞘内导管是否能预防硬膜穿刺后头痛（PDPH）。
使用18号Tuohy针进行腰椎穿刺。87例行骨科手术的患者通过20号导管给予0.5%布比卡因脊髓麻醉。术后，患者被随机分配，一组立即拔出导管（第1组，N = 47），另一组保留导管12至24小时（第2组，N = 40）。由一名不知情的观察者在术后第1、2、3和8天每天两次询问患者关于PDPH的情况。
PDPH的发生率为9.2%，两组相当（第1组5例，第2组3例）。
术后将鞘内导管保留12至24小时不能预防PDPH。
