Neurological follow-up of 281 children born in breech presentation: a controlled study
Insights
Breech presentation births have high perinatal mortality, mainly from pregnancy complications, not delivery method. Neurological outcomes for breech infants were similar to controls, suggesting current cesarean rates are appropriate.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Neurology
- Perinatal Medicine
Background:
- Breech presentation is a significant obstetric complication.
- Previous studies have raised concerns about neurological outcomes in breech infants.
- Optimal delivery management for breech presentation remains a topic of debate.
Purpose of the Study:
- To evaluate the long-term neurological development of children delivered in breech presentation.
- To compare neurological outcomes between breech infants and matched controls.
- To assess the safety and necessity of cesarean delivery for breech presentation.
Main Methods:
- A longitudinal study of children delivered in breech presentation between 1969 and 1977.
- Neurological examinations of surviving breech infants and matched controls at 18 months and later childhood.
- Analysis of perinatal mortality rates and causes in relation to delivery method.
Main Results:
- High perinatal mortality (13.2%) primarily due to non-delivery related causes.
- No significant differences in major neurological dysfunctions between breech and control groups.
- Minor neurological differences observed, with no clear link to delivery method.
Conclusions:
- The primary risks associated with breech presentation stem from pregnancy complications, not the delivery itself.
- Current rates of cesarean section (20%) for breech presentation are considered adequate.
- Routine increase in abdominal delivery frequency is not supported by these findings.
Abstract:
A study was conducted of all children delivered in breech presentation from 1969 to 1977 in the university's department of obstetrics. One-fifth of the deliveries were by caesarean section. Perinatal mortality was high (13.2%) but was due almost exclusively to causes other than the birth itself. The 256 surviving children and their matched controls were neurologically examined at 18 months or at ages varying between 3 and 10 years. The attrition rate was 5.7%, but in most cases data on development were available. Significant differences between the study and control groups existed for only minor neurological dysfunctions. It is concluded that the main danger of breech presentation is in the associated complications of pregnancy and that there is no reason to advocate a higher frequency of abdominal delivery than the 20% found in this study.
