Summary
The rate of Caesarean sections increased marginally, while perinatal mortality halved. This suggests rising C-section rates are not solely responsible for improved infant survival, indicating altered medical indications.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Health
- Surgical Outcomes
Background:
- A significant increase in Caesarean section rates has been observed globally over the past two decades.
- The relationship between rising Caesarean section rates and declining perinatal mortality is a subject of ongoing debate.
- Medical indications for Caesarean delivery have evolved, necessitating a re-evaluation of its impact on perinatal outcomes.
Purpose of the Study:
- To investigate the trend of Caesarean section rates and perinatal mortality over two distinct periods.
- To determine if the rise in Caesarean sections can solely account for the observed decrease in perinatal mortality.
- To analyze changes in the indications for Caesarean section deliveries.
Main Methods:
- Retrospective analysis of 7,274 deliveries.
- Comparison of Caesarean section rates and perinatal mortality between two biennial periods (1974-1975 and 1984-1985).
- Analysis of 650 Caesarean section cases to identify changes in indications.
Main Results:
- A marginal increase of 1.9% in the Caesarean section rate was observed between the two study periods.
- The overall perinatal mortality rate was halved during the second study period (1984-1985) compared to the first (1974-1975).
- Indications for Caesarean section delivery have changed in recent years.
Conclusions:
- The substantial rise in Caesarean section rates cannot be attributed solely to medical necessity.
- While indications for Caesarean section have altered, the marked increase in its rate is not the sole factor responsible for the significant reduction in perinatal mortality.
- Further research is needed to fully understand the complex interplay between surgical interventions and perinatal outcomes.
