Summary
Neonatal hemodynamics, including heart rate (HR) and cardiac output index (COI), decrease in the first hour after birth. Vaginal delivery is associated with higher hemodynamic function compared to Cesarean section (CS).
Area of Science:
- Neonatal physiology
- Cardiovascular adaptation
- Hemodynamic monitoring
Background:
- Early hemodynamic assessment is crucial for understanding neonatal outcomes and the impact of intrapartum events.
- Limited data exists on cardio-circulatory changes in the first 10 minutes post-birth.
- Electrical Cardiometry (EC) offers a noninvasive method for neonatal hemodynamic evaluation.
Purpose of the Study:
- To assess hemodynamic variables (HR, SVI, ICON, COI) in preterm and full-term infants during the first hour of life.
- To investigate the influence of delivery mode on cardiovascular adaptation.
- To establish trends in neonatal hemodynamics post-birth.
Main Methods:
- Prospective cohort study of 200 infants (full-term and preterm).
- Infants grouped by delivery mode and gestational age.
- Continuous hemodynamic monitoring using EC for the first hour.
Main Results:
- A significant decrease in HR, SVI, COI, and ICON was observed over the first hour (p < 0.001).
- Vaginally delivered infants showed significantly higher HR, COI, SVI, and ICON than those born via CS (p = 0.006, <0.001, 0.035, 0.001).
Conclusions:
- Neonatal HR, SVI, COI, and ICON consistently decrease in the first hour post-birth.
- Vaginal delivery is associated with higher hemodynamic parameters compared to Cesarean section.
- EC provides valuable insights into neonatal cardiovascular adaptation.
