Summary
Large birth weight (macrosomia) affects over 15% of newborns in Denmark, with increasing incidence. Prenatal diagnosis is challenging, but managing suspected macrosomia is crucial to prevent birth trauma.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Health
Context:
- Increasing incidence of high birth weight (macrosomia) in Denmark since 1989.
- Macrosomia poses diagnostic challenges using traditional methods like palpation and symphysis-fundus height measurement.
- Existing literature describes risk factors for macrosomia.
Purpose:
- To highlight the diagnostic difficulties of fetal macrosomia.
- To discuss the implications of macrosomia on infant and maternal health.
- To provide recommendations for managing suspected fetal macrosomia.
Summary:
- Fetal weight is frequently underestimated during prenatal assessment.
- Induction of labor for suspected macrosomia is generally not advised.
- Macrosomic infants delivered via cesarean section experience fewer birth injuries compared to vaginal delivery, though Apgar scores are unaffected.
Impact:
- Macrosomia is linked to increased birth trauma, with injury severity correlating with birth weight.
- Maternal complications are also more prevalent in cases of macrosomia.
- Early and accurate prenatal diagnosis, particularly ultrasound after 38 weeks, is vital for appropriate management, including potential elective cesarean section for suspected macrosomia over 5000g/5500g.
