Summary
This study analyzed 453 perinatal deaths, finding prematurity complications leading to death in high-risk pregnancies, while anoxia was common in uteroplacental insufficiency. Understanding these causes aids managing high-risk pregnancies.
Area of Science:
- Obstetrics and Gynecology
- Neonatology
- Pathology
Background:
- Perinatal mortality remains a significant concern in obstetrics.
- Understanding the specific causes of perinatal death is crucial for improving outcomes.
- Previous studies have explored perinatal mortality, but a detailed analysis by obstetric category is needed.
Purpose of the Study:
- To investigate the causes of perinatal death by categorizing them based on obstetric diagnoses.
- To determine the relationship between specific obstetric conditions and infant causes of death.
- To inform the management of high-risk pregnancies by clarifying risks.
Main Methods:
- A multidisciplinary team reviewed 453 consecutive perinatal deaths from 1978-1982.
- Obstetric and infant causes of death were diagnosed and assigned principal diagnoses.
- Perinatal death rates were calculated for different obstetric categories.
Main Results:
- Perinatal death rates varied significantly, from 6.1/1000 births in uncomplicated cases to 217.4/1000 births in isolated intrauterine growth retardation.
- Complications of prematurity (65%) were the leading cause of death with third-trimester bleeding, premature labor, or premature rupture of membranes.
- Anoxia (59%) was the most frequent cause of death in cases of hypertension/pre-eclampsia or uteroplacental insufficiency. Congenital abnormalities accounted for 17.7% of deaths.
Conclusions:
- Categorizing perinatal deaths by obstetric diagnosis highlights distinct risk factors.
- Prematurity and anoxia are key causes of death, with their prevalence depending on the obstetric condition.
- This approach aids in risk assessment and management strategies for high-risk pregnancies.
