In an attempt to assess the extent to which contamination by exogenous squamous cells contributes to false-positive results in the cytologic diagnosis of amniotic fluid embolism, blood sampled from the right heart or from the pulmonary artery of 42 nonpregnant cardiac patients was processed and examined for squames. Despite a variety of precautions, it proved impossible to eliminate contamination in any of these specimens. In addition, two of three blank slides that were stained with maximal precaution also demonstrated squames. The authors conclude that cytologic techniques are not helpful in the diagnosis of amniotic fluid embolism and should no longer be utilized.
为了评估外源性鳞状细胞污染在羊水栓塞细胞学诊断中导致假阳性结果的程度，对42名非妊娠心脏病患者的右心或肺动脉采集的血液进行了处理，并检查其中的鳞状上皮细胞。尽管采取了各种预防措施，但事实证明无法消除这些样本中的污染。此外，在采取最大预防措施染色的三张空白载玻片中，有两张也显示有鳞状上皮细胞。作者得出结论，细胞学技术对羊水栓塞的诊断没有帮助，不应再使用。
