Meconium in amniotic fluid increases the risk of perinatal infections like chorioamnionitis and endometritis. This review explores meconium pathophysiology and its link to infection, impacting fetal and neonatal well-being.

Area of Science:

Obstetrics and Gynecology
Neonatology
Infectious Diseases

Background:

Meconium-stained amniotic fluid (MSAF) incidence ranges from 7-22%.
The pathophysiology of MSAF is not fully understood.
MSAF is a recognized risk factor for fetal and neonatal well-being.

Purpose of the Study:

To review the pathophysiology of meconium.
To examine the contribution of meconium to perinatal infection incidence.

Main Methods:

Review article.
Analysis of meconium's role in intraamniotic infection, chorioamnionitis, endometritis, and neonatal infections.

Main Results:

Clinical chorioamnionitis incidence is 15% with MSAF vs. 3% in controls.

Related Experiment Videos

Puerperal endometritis incidence is 10% with MSAF vs. 3% in controls.

Mechanisms include infection causing meconium passage or meconium impairing immune response.

Conclusions:

Meconium presence significantly elevates the risk of various perinatal infections.
Alterations in amniotic fluid's Zn/P ratio and impaired cellular immunity contribute to infection development.
Antibiotic prophylaxis strategies are discussed in the context of MSAF.
