Key result
Gestational diabetes mellitus is linked to higher baseline fetal heart rate and longer low-variation episodes.
Why the study?
The impact of gestational diabetes mellitus on fetal heart rate patterns assessed by computerized cardiotocography and its relation to neonatal outcomes was evaluated.
Does computerized cardiotocography detect fetal heart rate alterations in pregnancies complicated by gestational diabetes mellitus compared to normal pregnancies?
Observational (n=260)
Does computerized cardiotocography detect fetal heart rate alterations in pregnancies complicated by gestational diabetes mellitus compared to normal pregnancies?
Computerized cardiotocography can detect slight but significant alterations in fetal heart rate in pregnancies complicated by gestational diabetes mellitus, which correlate with neonatal reactivity.
May support computerized CTG monitoring in GDM; hypothesis-generating and should not yet change practice.
Objective. We evaluated the value of computerized cardiotocography (cCTG) in pregnancies complicated by gestational diabetes mellitus (GDM).Purpose of study. We studied fetal heart rate (FHR) recordings from 100 pregnant women affected by GDM on diet therapy, 60 pregnant women affected by GDM on insulin therapy and 100 normal pregnant controls. The results were compared among the groups and related to neonatal umbilical artery cord blood analysis at birth.Research design and methods. Baseline FHR and the duration of episodes of low variation were significantly higher in diabetic than in controls and were negatively related to umbilical artery glycemia at birth, whereas the short-term variation in diabetics was significantly lower than in controls and was positively related to.Conclusions. Our study demonstrates that GDM does impact FHR. The alteration is slight but evident; it reflects fetal well being and correlate with neonatal reactivity. Only cCTG may allow to detect those slight but significant differences.

Buscicchio et al. (2010) conducted an observational in Gestational diabetes mellitus (n=260). Gestational diabetes mellitus vs. Normal pregnant controls was evaluated on Fetal heart rate (FHR) parameters (baseline FHR, duration of episodes of low variation, short-term variation). Gestational diabetes mellitus significantly altered fetal heart rate parameters, increasing baseline FHR and duration of low variation episodes compared to normal pregnant controls.
