What is Longitudinal Changes of Cardiotocographic Parameters Throughout Pregnancy: a Prospective Cohort Study Comparing Small-for-gestational-age and Normal Fetuses from 24 to 40 Weeks about?

## Objective: To compare longitudinal trends of cardiotocographic (ctg) parameters between small-for-gestational-age (sga) and normal fetuses, from 24 to 41 weeks of pregnancy. ## Methods: A prospective cohort study was carried out in singleton pregnancies without fetal malformations. at least one ctg was performed in each of the following intervals: 24-26 weeks+6 days, 27-29 weeks+6 days, 30-32 weeks+6 days, 33-35 weeks+6 days, 36-38 weeks+6 days and ≥39 weeks. tracings were analyzed using the omniview-sisporto® 3.6 system. cases with a normal pregnancy outcome, including a birthweight ≥10th percentile for gestational age, were compared with two groups of sga fetuses: with birthweight <10th percentile (sga ## Results: A total of 176 fetuses (31 sga) and 1256 tracings (207 from sga fetuses) were evaluated. all ctg parameters changed significantly throughout pregnancy in the three groups, with a decreasing baseline and probability of decelerations, and an increasing average long-term variability (ltv), average short-term variability (stv) and accelerations. baseline showed a more pronounced decrease (steeper slope) in sga fetuses, being higher in these cases at earlier gestational a
