Summary
Increased blood viscosity during pregnancy may indicate fetal growth issues. This study found higher viscosity in pregnant women with fetuses experiencing intrauterine growth retardation, suggesting a link to placental circulation problems.
Area of Science:
- Obstetrics and Gynecology
- Hemorheology
- Perinatal Medicine
Context:
- Pregnancy involves significant physiological changes, including alterations in hemorheological parameters.
- Understanding these changes is crucial for monitoring fetal well-being and identifying potential complications.
Purpose:
- To investigate changes in hemorheological parameters during the third trimester of pregnancy.
- To determine if altered blood viscosity is associated with intrauterine growth retardation (IUGR).
Summary:
- Whole blood viscosity, hematocrit, plasma viscosity, and hemoglobin were measured in pregnant women.
- No significant changes were observed in healthy pregnancies, but viscosity increased later in pregnancy for macrosomic fetuses.
- Higher blood viscosity was noted in women who delivered fetuses with growth retardation.
Impact:
- Suggests that progressively increasing blood viscosity in late pregnancy may disrupt intervillous microcirculation.
- Provides evidence linking hemorheological changes to the etiology of intrauterine growth retardation.
- Highlights the potential of hemorheological monitoring for identifying pregnancies at risk for fetal growth issues.
