Measurement of Placental Index in Different Gestational Age Groups in Bangladeshi Women.

Placenta is the mirror of maternal and fetal status; it reflects the changes due to complications in pregnancy of mother. The growth and survival of the fetus in utero is directly related to formation, development and maturation of the placenta. Placental index was correlated to poor pregnancy outcomes. Placental index can help to identify fetal growth restriction which is result of placental insufficiency and is characterized by insufficient trasnsplacental transport of nutrients and oxygen. This cross sectional descriptive study would provide information about the ratio of placental index in different gestational age group in Bangladeshi women. To achieve this aim the study was performed on 60 human placenta and corresponding fetuses and gestational age (in weeks) categorized as Group A (28-32), Group B (33-37), Group C (38-40). These sample and information were collected from normal pregnancy in Gynecology and Obstetrics Department of Mymensingh Medical College Hospital from July 2009 to June 2010. After preservation in 10% formal saline, study was done in Department of Anatomy in Mymensingh Medical College. In this study, the mean±SD placental index was in Group A (0.187±0.113), Group B (0.153±0.025) and Group C (0.166±0.025) and also observed that mean placental index decreased with age up to certain level then increase in Group C. The mean placental index was maximum in Group A (0.187±0.113) and was minimum in Group B (0.153±0.025). The mean difference of placental index between Groups A&B, A&C and B&C was statistically not significant. Observed findings of this study were compared with those of Western and Bangladeshi researches.
