We have conducted a prospective study into the ease of use and incidence of postdural puncture headache with the 'Portex' combined spinal/epidural set. The pack contains a 16-gauge Tuohy needle of standard 8 cm shaft length with a matching 26-gauge pencil point spinal needle. The study included 150 consecutive combined spinal/epidural anaesthetics for lower segment Caesarean section. Eighty-eight percent of the cases fulfilled the criteria as technically perfect, i.e. cerebrospinal fluid obtained at the first attempt after identifying the epidural space. There were two cases of significant postdural puncture headache requiring blood patch due to puncture by the 26-gauge spinal needle giving an incidence of 1.3%. This compares favourably with previously reported rates in obstetric patients.
我们对“Portex”腰麻-硬膜外联合套件的易用性和腰麻后头痛的发生率进行了一项前瞻性研究。该套件包含一根16号、针身长8厘米的标准Tuohy针以及一根配套的26号铅笔尖腰麻针。该研究纳入了150例连续进行下段剖宫产的腰麻-硬膜外联合麻醉病例。88%的病例在技术上堪称完美，即在确定硬膜外间隙后首次穿刺就获得了脑脊液。有2例因26号腰麻针穿刺导致严重的腰麻后头痛，需要进行血补丁治疗，发生率为1.3%。这与先前报道的产科患者发生率相比更具优势。
