[Expanded indications for cesarean section for low birth weight infants]
Insights
Caesarean sections significantly improve outcomes for low birth weight infants (1,001–2,000 gm), especially breech presentations. For larger infants (2,001–2,500 gm), spontaneous delivery offers the lowest perinatal mortality.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Neonatal Research
Context:
- Retrospective analysis of 849 low birth weight infants (1,001–2,500 gm) born between 1966 and 1982.
- Infants categorized into three birth weight groups: 1,001–1,500 gm, 1,501–2,000 gm, and 2,001–2,500 gm.
- Comparison of perinatal mortality rates across spontaneous delivery, manual assistance, and caesarean section.
Purpose:
- To evaluate the impact of delivery mode on perinatal mortality in low birth weight infants.
- To determine optimal delivery strategies for different birth weight strata.
- To provide evidence-based recommendations for managing breech and vertex presentations in low birth weight neonates.
Summary:
- In infants weighing 1,001–1,500 gm, caesarean section had a 19% perinatal mortality, compared to 32% for spontaneous and 45% for manual assistance.
- For infants weighing 1,501–2,000 gm, caesarean section showed a 10% perinatal mortality, versus 16% for spontaneous and 14% for manual assistance.
- Caesarean sections significantly improved prognosis for infants in the 1,001–2,000 gm range, with recommendations for breech presentations and complex vertex presentations.
Impact:
- Highlights the benefits of caesarean sections for specific low birth weight infant groups, particularly those with breech presentations.
- Suggests that for infants between 2,001–2,500 gm, spontaneous delivery has the lowest perinatal mortality (4.1%).
- Informs clinical practice regarding delivery mode selection to minimize perinatal mortality in low birth weight neonates.
Abstract:
Retrospective investigations on 849 low birth weight infants between 1,001 and 2,500 gm born from 1966 to 1982 were done. The infants were divided into three groups with birth weights from 1,001 to 1,500 gm, from 1,501 to 2,000 gm, and 2,001 to 2,500 gm. The results of spontaneous delivery, delivery with manual assistance and caesarian section were compared. In the weight group 1,001 to 1,500 gm (14%), the perinatal mortality was 32%. In caesarian sections, the perinatal mortality was 19%, in spontaneous deliveries the perinatal mortality was 32% and in delivery with manual assistance the perinatal mortality was 45%. In the second weight group of 1,501 to 2,000 gm the perinatal mortality was 14.8%. Spontaneous delivery had a perinatal mortality of 16%, manual assistance a perinatal mortality of 14% and caesarian section a perinatal mortality of 10%. In both birth weight groups of 1,001 to 1,500 gm and 1,001 to 2,000 gm, the infants born by caesarian section had a significantly improved prognosis. Therefore, we recommend caesarian section in these weight groups for all breech presentations. In vertex presentations, caesarian sections are indicated when additional risk factors especially prolonged labour are apparent. In the third weight group between 2,001 and 2,500 gm the overall perinatal mortality was 4.9%. The spontaneously delivered infants have a mortality of 4.1%. Manual assistance was associated with a perinatal mortality of 5.9%. Caesarian section had a perinatal mortality of 11%.(ABSTRACT TRUNCATED AT 250 WORDS)
