Summary

Maternal glucose loading impacts fetal cardiac function. Left ventricular function changed significantly in appropriate for date infants, while high-risk fetuses showed adverse changes in both left and right cardiac functions.

Area of Science:

  • Obstetrics and Gynecology
  • Fetal Medicine
  • Cardiology

Background:

  • Maternal glucose metabolism can influence fetal development.
  • Assessing fetal cardiac function is crucial for monitoring fetal well-being.
  • Understanding the impact of maternal glucose on fetal hemodynamics is important.

Purpose of the Study:

  • To investigate the effects of maternal intravenous glucose administration on fetal cardiac function.
  • To compare fetal cardiac responses in appropriate for date (AFD) infants, light for date (LFD) infants, and a high-risk fetus.

Main Methods:

  • M-mode echocardiography was used to assess fetal cardiac function.
  • Maternal intravenous injection of 20g glucose was administered.
  • Fetal heart rate, left and right ventricular fractional shortening, and cardiac output were measured.

Main Results:

  • Maternal glucose loading did not significantly alter fetal heart rate in any group.
  • Left ventricular function showed significant changes in AFD infants but not LFD infants.
  • A high-risk fetus (Case 1) exhibited adverse changes in both left and right cardiac functions.

Conclusions:

  • Maternal glucose loading alters fetal cardiac function, particularly left ventricular performance.
  • Fetal cardiac response to maternal glucose varies based on fetal growth status and maternal health conditions.
  • Severe toxemia of pregnancy may lead to compromised fetal cardiac adaptation to maternal glucose challenges.
