Objective: To calculate Placental Weight to Birth Weight Ratio and its effect among neonates delivered at tertiary care center.
Study Design: Cross-sectional study.
Place and Duration of Study: Obstetrics and Gynecology Department of a tertiary care center, Karachi Pakistan, from Dec 2019 to Feb 2020.
Methodology: Booked cases with singleton pregnancies and gestational ages more than 37 weeks at birth were considered. On a manual scale, the placenta was weighed to the nearest gram. Immediately following delivery, the birth weight of babies was recorded to the nearest gram on the same manual weighing equipment. At 01 minute and 05 minutes, the APGAR scores were noted as well.
Results: The mean age of our respondents was 29.05±5.27 years old. Placental Weight to Birth Weight Ratio ratios were substantially greater in newborns with low APGAR scores than those with high APGAR scores at 1 minute (p=0.001), and the median Placental Weight / Birth Weight was also significantly higher in those infants at 5 minutes (p=0.001).
Conclusion: Poor perinatal outcomes, such as low APGAR scores at 1 and 5 minutes after birth, are associated with high Placental Weight/Birth Weight ratio.
