One hundred elderly male patients undergoing transurethral surgery were allocated randomly to receive spinal anaesthesia with either a 26 gauge Yale needle or a 24 gauge Sprotte needle. Patients were visited within 48 h by an investigator who was unaware of the needle type used and specific enquiry was made about any headache which was characteristic of dural puncture. We found evidence of a postdural puncture headache in 15 (30%) patients in whom a 26 gauge Yale needle was used. By comparison, only three patients (6%) in the Sprotte group reported a postdural puncture headache. This represents a highly significant (P < 0.005) reduction in the incidence of postdural puncture headache. The incidence of multiple attempts at dural puncture was also significantly (P < 0.05) reduced to 16% in the Sprotte group compared with 28% in the Yale group.
100名接受经尿道手术的老年男性患者被随机分配，分别使用26号耶鲁针或24号斯普罗特针进行脊髓麻醉。一名不知道所使用针具类型的研究者在48小时内对患者进行访视，并就任何具有硬膜穿刺特征的头痛进行了具体询问。我们发现，在使用26号耶鲁针的15名（30%）患者中存在硬膜穿刺后头痛的证据。相比之下，斯普罗特组只有3名患者（6%）报告有硬膜穿刺后头痛。这表明硬膜穿刺后头痛的发生率显著降低（P < 0.005）。与耶鲁组28%相比，斯普罗特组硬膜穿刺多次尝试的发生率也显著降低（P < 0.05），降至16%。
