The important features which determine the ease of use of spinal needles include rapid detection of cerebrospinal fluid, minimal delay before injection and low resistance to injection of local anaesthetic. We investigated these three parameters among the following 11 spinal needles: Becton-Dickinson 22 G, 25 G and 27 G Whitacre, 25 G and 27 G Quincke; B. Braun Spinocan 22 G, 25 G and 26 G Quincke; Vygon 25 G Whitacre, Portex 26 G Pencil Point and the 24 G Sprotte. Three needles of each type were tested using an artificial cerebrospinal fluid model maintained at body temperature and at two hydrostatic pressures of 12 and 50 cm of water. The Becton Dickinson 27 G Whitacre has an immediate detection time at both pressure heights, a reasonably short 'ready to inject' time and relatively low resistance to injection, which, together with a reported low rate of postdural puncture headache, would indicate that it is the most appropriate for spinal anaesthesia. The 25 G Whitacre types would be the next most suitable to use.
决定脊椎穿刺针易用性的重要特征包括快速检测脑脊液、注射前延迟最短以及对局部麻醉剂注射的低阻力。我们在以下11种脊椎穿刺针中研究了这三个参数：贝克顿-迪金森22G、25G和27G惠塔克针，25G和27G昆克针；贝朗Spinocan 22G、25G和26G昆克针；维贡25G惠塔克针、波泰克斯26G铅笔尖针和24G斯普罗特针。每种类型的三根针在体温下以及12厘米水柱和50厘米水柱这两种静水压力下，使用人工脑脊液模型进行测试。贝克顿-迪金森27G惠塔克针在两种压力高度下都有即时检测时间、相当短的“准备注射”时间以及相对较低的注射阻力，再加上报道的低硬膜穿刺后头痛发生率，这表明它最适合用于脊椎麻醉。25G惠塔克类型的针将是其次最适合使用的。
