ABSTRACT
Objective: To determine the mean placental birth weight ratio at term in
primigravidae
Study design: Cross-sectional study
Place and Duration: Department of Obstetrics and Gynecology, Civil Hospital Karachi,
duration was six months after the approval of synopsis from 1st January
2016 to 30th June 2016
Subjects and Methods: A total of pregnant women who fulfill the inclusion criteria were
included in this study. After delivery, baby was weighed by using weight
machine and weight of baby was also noted (as per operational definition).
After expulsion of complete placenta, placental weight was measured by using
weight machine. The placental-birth weight ratio (PBWR) were calculated as
ratio of placental weight to neonatal weight multiplied by 100.
Results: Mean ± SD of maternal age was 24.77±4.04 with C.I (24.11----25.42)
years. Mean ± SD of placental weight was 505.84±99.97 with C.I (489.71----521.97)
grams. Out of 150 neonatal babies 101 (67.3%) were male and 49 (32.7%) were
female. Mean placental birth weight ratio was found to be 16.82±2.63 with C.I
(16.39----17.24).
Conclusion: It is to be concluded that placental weight increased according to the
birth weight. The placental weight to birth weight ratio decreased slightly
with advancing gestational age.
