A Survey on Diagnosis and Prognosis of Prenatal Asphyxia based on Antioxidant Oxidant Balance: Evidence from a Systematic Review and Meta-Analysis.
Hassan et al., Curr Pediatr Rev 2024

Summary of Findings:
The study presents a meta-analysis examining the relationship between prooxidant-antioxidant balance (PAB) and malondialdehyde (MDA) levels with the risk and prognosis of prenatal asphyxia in newborns. The analysis included 13 studies and found that:
- Neonates with asphyxia had PAB levels twice as high as normal newborns.
- Neonates with asphyxia and adverse prognosis had PAB levels three times higher than those with a favorable prognosis.
- The sensitivity of PAB in predicting neonatal asphyxia prognosis was 83-89%, and specificity was 71-92%.
- A significant association was found between PAB and MDA levels with the risk of prenatal asphyxia (SMD = 1.447, 95%CI: 0.961-1.934, P < 0.001).
This suggests that measuring antioxidant enzymes and oxidant agents, and assessing their balance, could be useful in diagnosing and predicting the prognosis of neonatal asphyxia.
Importance:
This research contributes to the understanding of prenatal asphyxia by highlighting the importance of oxidative stress markers in its diagnosis and prognosis. It provides evidence that could lead to improved diagnostic and prognostic tools for this condition.
Contribution to Literature:
The study adds to the current literature by systematically reviewing and quantifying the association between oxidative stress markers and prenatal asphyxia, which has not been comprehensively done before. It offers a quantitative measure of the relationship between PAB and MDA levels and the risk of prenatal asphyxia, which could be crucial for clinical assessments.
Limitations:
The study acknowledges limitations such as incomplete access to all relevant articles, variability in the quality of reports, and differences in diagnostic methods for prenatal asphyxia across studies.
