A randomized study was carried out on 160 patients aged 30-60 years with the aim of finding a method of preventing postdural puncture headache (PDPH). In Taylor's lumbosacral approach to the subarachnoid space, two different needle sizes were used (21-gauge versus 25-gauge) for injecting the anaesthetic solution. Our results show an overall incidence of PDPH in nearly 8% of patients, with no significant difference related to the size of the needle employed. Patients with PDPH showed mild symptoms which disappeared in a short time and none needed epidural blood patching. The possibility of using larger needles, facilitating the execution of the block without increasing PDPH incidence, renders this technique particularly attractive in patients where the midline approach is not feasible, or when pencil-point needles are not available.
对160名年龄在30至60岁之间的患者进行了一项随机研究，目的是找到一种预防硬膜穿刺后头痛（PDPH）的方法。在泰勒腰骶部蛛网膜下腔穿刺法中，使用了两种不同规格的针头（21号与25号）注射麻醉溶液。我们的结果显示，PDPH的总体发生率在近8%的患者中，与所用针头的规格无显著差异。PDPH患者表现出轻微症状，短时间内消失，无一例需要硬膜外血贴补。使用较大针头有助于在不增加PDPH发生率的情况下实施阻滞，这使得该技术在中线穿刺法不可行或没有笔尖式针头时对患者特别有吸引力。
