To investigate the differences in the number of squamous epithelial cells carried to the spinal canal by three different types of spinal needle tip of the same size.
Patients were allocated into three groups (Group I, Group II, Group III). Spinal anesthesia was administered to Group I (n=50) using a 25G Quincke needle, to Group II (n=50) using a 25G pencil point spinal needle, and to Group III (n=50) using a non-cutting atraumatic needle with special bending. The first and third drops of cerebral spinal fluid (CSF) samples were taken from each patient and each drop was placed on a slide for cytological examination. Nucleated and non-nucleated squamous epithelial cells on the smear preparations were counted.
There was statistically significant difference between the groups in respect to the number of squamous epithelial cells in the first drop (p<0.05). Group III had lower number of squamous epithelial cells in the first drop compared to that of Group I and Group II. Mean while Group I had higher number of squamous epithelial cells in the third drop compared to the other groups. The number of squamous epithelial cells in the first and third drops was statistically similar in each group respectively (p>0.05 for each group).
In this study of different needle tips, it was seen that with atraumatic needle with special bending a significantly smaller number of cells were transported when compared to the Quincke tip needles, and with pencil point needles.
研究三种相同尺寸的不同类型脊髓穿刺针尖端带入椎管的鳞状上皮细胞数量差异。
将患者分为三组（第一组、第二组、第三组）。第一组（n = 50）使用25G Quincke针进行脊髓麻醉，第二组（n = 50）使用25G铅笔头脊髓穿刺针，第三组（n = 50）使用具有特殊弯曲的无切割无创伤针。从每位患者采集脑脊液（CSF）样本的第一滴和第三滴，每一滴置于载玻片上进行细胞学检查。对涂片制备物上的有核和无核鳞状上皮细胞进行计数。
各组第一滴样本中鳞状上皮细胞数量存在统计学显著差异（p < 0.05）。与第一组和第二组相比，第三组第一滴样本中的鳞状上皮细胞数量较少。同时，与其他组相比，第一组第三滴样本中的鳞状上皮细胞数量较多。每组第一滴和第三滴样本中鳞状上皮细胞数量分别在统计学上相似（每组p > 0.05）。
在这项关于不同针尖的研究中，发现与Quincke针尖针和铅笔头针相比，具有特殊弯曲的无创伤针带入的细胞数量明显较少。
