Maternal and perinatal morbidity resulting from placenta previa

Area of Science:

• Obstetrics
• Maternal-Fetal Medicine
• Neonatology

Background:

• Placenta previa presents significant risks to both mother and fetus.
• Understanding risk factors and outcomes is crucial for improved management.

Purpose of the Study:

• To review cases of placenta previa and analyze associated maternal and fetal outcomes.
• To identify factors influencing maternal morbidity and perinatal mortality.

Main Methods:

• Retrospective review of 147 partial or complete placenta previa cases from 1975 to 1982.
• Analysis of maternal history, bleeding patterns, delivery timing, and neonatal outcomes.

Main Results:

• Prior cesarean section correlated with increased maternal morbidity (hemorrhage, accreta, hysterectomy).
• Two-thirds of patients delivered before 36 weeks gestation, despite interventions.
• Early bleeding (before 20 weeks) indicated poor fetal prognosis.
• Perinatal mortality rate was 81/1000; respiratory distress syndrome occurred in 22% of neonates.
• Maternal hemorrhage linked to neonatal transfusion needs; neonatal anemia correlated with intrapartum blood loss.

Conclusions:

• Prior cesarean delivery is a significant risk factor for severe maternal complications in placenta previa.
• Placenta previa is associated with high rates of preterm birth and significant perinatal mortality.
• Antepartum hemorrhage and neonatal complications are closely linked, highlighting the need for careful monitoring and management.
