Summary
Two labor courses involving fetuses with growth restrictions were managed. Umbilical venous blood analysis revealed normal pH, successfully avoiding cesarean sections.
Area of Science:
- Perinatology
- Fetal Medicine
- Obstetrics
Background:
- Intrauterine growth restriction (IUGR) poses significant risks to fetal well-being.
- Abnormal fetal heart rate patterns during labor often necessitate urgent intervention, including cesarean delivery.
- Management decisions for growth-restricted fetuses require careful consideration of fetal status.
Observation:
- Two cases of labor in pregnancies complicated by fetal growth restriction are presented.
- Cordocentesis was performed due to concerning fetal heart rate patterns.
- Cervical dilation was insufficient for immediate delivery in both instances.
Findings:
- Analysis of umbilical venous blood samples obtained via cordocentesis.
- Normal fetal blood pH levels were recorded in both cases.
- This finding indicated adequate fetal oxygenation and acid-base balance.
Implications:
- Normal umbilical venous pH can guide clinical decisions, potentially avoiding unnecessary operative interventions.
- This approach may help prevent cesarean deliveries in select cases of fetal growth restriction with abnormal heart rate patterns.
- Further research into the utility of cordocentesis for intrapartum fetal assessment in IUGR is warranted.
