In 126 pregnant women of the gestational age from the 28th to the 44th gestational week, the biparietal diameter, the abdomen diameter, and the placental maturity after Granum et al. were determined. Amniocentesis was performed for obstetric indication. Also the L/S ratio and the cytological estimation of the gestational age were recorded. The first degree of the placental maturity was found in 37, the second degree in 3, and the third degree in 36 pregnant women. In the first group, BPP was 8.38 +/- 0.75, the abdomen diameter 8.30 +/- 0.63, and pulmonary maturity in 73% of women according to the L/S ratio and in 91.9% according to cytological estimation. In the second group, BPP was 9.15 +/- 0.65, the abdomen diameter 9.03 +/- 0.83, and in 77.9% of women the L/S ratio was higher than 2 but in 56.6% of women, according to cytological estimation, there was a good pulmonary maturity. At the third degree of placental maturity, BPP was 9.49 +/- 0.60, the abdomen diameter 9.63 +/- 0.92, and a good pulmonary maturity in 94.4% of women. The RDS was not observed in 5.6% of newborns with the L/S ratio below 2. According to cytological estimation, BPP below 9.15 was found in pre-term labour and higher than 9.15 in at-term births when in 94% of women the L/S ratio was higher than 2.
对126例孕龄在妊娠第28周到第44周的孕妇，测定了双胎双顶径、腹径以及按照格拉努姆等人方法确定的胎盘成熟度。因产科指征进行了羊膜穿刺术。还记录了L/S比值和孕周的细胞学评估结果。37例孕妇胎盘成熟度为一级，3例为二级，36例为三级。第一组中，生物物理评分（BPP）为8.38±0.75，腹径为8.30±0.63，根据L/S比值，73%的孕妇肺成熟，根据细胞学评估为91.9%。第二组中，BPP为9.15±0.65，腹径为9.03±0.83，77.9%的孕妇L/S比值高于2，但根据细胞学评估，56.6%的孕妇肺成熟良好。胎盘成熟度为三级时，BPP为9.49±0.60，腹径为9.63±0.92，94.4%的孕妇肺成熟良好。L/S比值低于2的新生儿中，5.6%未观察到呼吸窘迫综合征（RDS）。根据细胞学评估，早产时BPP低于9.15，足月分娩时高于9.15，此时94%的孕妇L/S比值高于2。
