Our objective was to determine whether wiping of the cervix before taking a Papanicolaou smear aided cytological interpretation.
Three hundred nine women were randomly assigned to one of two groups. In one group, the subjects' cervixes were wiped before Papanicolaou smears were obtained. Smears were taken by uniformly trained practitioners and were read by cytologists in a blind fashion.
There were no demographical differences between groups, nor were there differences between groups as to the quality of the smears or the diagnoses made. There were differences between groups as to remarks made by cytologists. The nonwiped group had thicker smears (p = .006) and more inflammation (p = .04). The wiped group showed more drying artifact (p = .001), crush artifact (p = .005), and limited cellular material (p = .007).
It would appear that though there are no marked differences between the two techniques, wiping the cervix before obtaining the smear leads to less cellular material for comparison and predisposes to air drying. This technique may be less beneficial than was thought.
我们的目的是确定在进行巴氏涂片检查之前擦拭宫颈是否有助于细胞学解释。
309 名女性被随机分为两组。在一组中，在进行巴氏涂片检查之前擦拭了受试者的宫颈。涂片由经过统一培训的医生进行采集，并由细胞学专家进行盲法读取。
两组之间在人口统计学方面没有差异，涂片质量或诊断结果也没有差异。但两组之间细胞学专家的评论存在差异。未擦拭组的涂片较厚（p =.006），炎症更多（p =.04）。擦拭组显示出更多的干燥伪影（p =.001）、压碎伪影（p =.005）和有限的细胞材料（p =.007）。
尽管两种技术之间没有明显差异，但在获取涂片之前擦拭宫颈会导致用于比较的细胞材料减少，并容易导致空气干燥。这种技术可能不像以前认为的那样有益。
