A spectrophotometric method is presented for use during amnioscopy for the estimation of the colour of amniotic fluid. The application of five different filters was tested; and a ratio of the results obtained using filters with mean wave-lengths of 621 nm and 589 nm was found to be the most reliable parameter for the detection of green coloured amniotic fluid. Preliminary results are so promising that further examinations and a development of the method are indicated. Various improvements to the method are also discussed.
本文介绍了一种用于羊膜镜检查期间估计羊水颜色的分光光度法。测试了五种不同滤光片的应用；发现使用平均波长为621纳米和589纳米的滤光片所获得结果的比率是检测绿色羊水最可靠的参数。初步结果非常有前景，表明需要进一步检查并改进该方法。还讨论了对该方法的各种改进。
