Color doppler study of occupational tobacco exposure effects on fetoplacental circulation among pregnant bidi workers and pregnant non bidi workers
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 2
Abstract
Background: While preparing bidies by pregnant women, ingredients of tobacco are likely to be absorbed through intact skin of the hands and inhaled as fine dust. Doppler ultrasound, a new noninvasive technique is used to assess the qualitative aspects of uteroplacental circulation. In this study we have tried to study fetoplacental circulation in pregnant bidi workers and compared with pregnant non bidi workers. Material and Methods: The study population comprises two equal groups of 100 women each with singleton pregnancies of bidi worker and non-bidi workers at 37-38 weeks gestational age. Color Doppler and pulsed Doppler velocimetry (L and T Company) was carried out to assess Resistance index, Amniotic fluid index and umbilical artery to study fetoplacental circulation. Results: Pregnant bidi workers have higher uterine artery RI as compared to pregnant non bidi workers. Doppler velocimetry of the uterine arteries reflects vascular impedance on the maternal side of the placental circulation. Pregnant bidi workers have higher umbilical artery S/D ratio as compared to pregnant non bidi workers. Discussion: In placental insufficiency, the resistance to blood flow increases in the placental vessels, which is reflected in the umbilical artery Doppler as increased S/D ratio, RI and PI.Color Doppler is useful in studying adverse effects of tobacco handling in bidi workers on fetoplacental circulation. Pregnant bidi workers should get dietary allowance and paid leave and measures such as gloves and masks to prevent tobacco exposure.
