Retained placenta and associated risk factors.

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine
• Maternal-Fetal Medicine

Background:

• Retained placenta is a significant obstetric complication with potential maternal morbidity.
• Identifying predictive factors for retained placenta is crucial for timely intervention and improved patient outcomes.
• Previous studies have explored various risk factors, but a comprehensive analysis is warranted.

Purpose of the Study:

• To identify and analyze the key factors associated with the retention of placenta in a cohort of patients.
• To compare risk factors in patients with retained placenta versus those with uncomplicated vaginal delivery.
• To provide clinicians with a better understanding of risk stratification for retained placenta.

Main Methods:

• Retrospective case-control study involving 146 patients with retained placenta and 300 controls.
• Data collected on maternal age, parity, antenatal abnormalities, labor characteristics, uterine surgery history, and previous retained placenta.
• Statistical analysis to determine the significance of various factors in relation to retained placenta.

Main Results:

• Significant risk factors for retained placenta, in descending order of significance, include: history of retained placenta, previous uterine surgery, preterm delivery, maternal age >35 years, placental weight <601g, pethidine use, labor induction, and high parity (>5).
• The presence of multiple risk factors increases the likelihood of retained placenta.
• Specific labor characteristics and maternal history were strongly correlated with the complication.

Conclusions:

• History of retained placenta and previous uterine surgery are the most significant predictors.
• Obstetricians should be vigilant for retained placenta in patients presenting with a combination of identified risk factors.
• Early identification and management strategies can be informed by these findings to reduce maternal complications.
