Atenolol and short umbilical cords
American Journal of Obstetrics and Gynecology
|May 1, 1987
Summary
Atenolol, a beta-blocker, significantly shortened umbilical cords in rabbit fetuses. This finding suggests careful monitoring of pregnancies exposed to beta-blocking agents is crucial due to potential labor complications.
Area of Science:
- Reproductive biology
- Pharmacology
- Developmental toxicology
Background:
- Umbilical cord length is critical for fetal development and can be influenced by fetal activity.
- Certain medications may impact fetal movement and subsequently affect umbilical cord development.
- Short umbilical cords are linked to adverse pregnancy outcomes, including labor difficulties and low Apgar scores.
Purpose of the Study:
- To investigate the impact of the beta-blocker atenolol on umbilical cord length in a rabbit model.
- To determine if atenolol-induced changes in fetal movement correlate with alterations in umbilical cord length.
Main Methods:
- Pregnant rabbits were administered atenolol.
- Umbilical cord lengths of fetuses from treated rabbits were compared to those from control animals.
- Statistical analysis was performed to assess the significance of observed differences (p ≤ 0.0005).
Main Results:
- Fetuses exposed to atenolol exhibited significantly shorter umbilical cords compared to the control group.
- The reduction in umbilical cord length was statistically significant, indicating a clear effect of atenolol.
Conclusions:
- Beta-blocker atenolol can lead to shorter umbilical cords in fetal development.
- Close monitoring of pregnant individuals receiving beta-blocking agents, particularly within the first 30 weeks of gestation, is recommended.
- Short umbilical cords pose risks, necessitating vigilance for potential complications in affected pregnancies.
