PROJECT SUMMARY The umbilical cord is the essential lifeline of fetus supplying nutrients, oxygen and fluids necessary for life in utero. The trivascular conduit is well protected by Whartons jelly, amniotic fluid and the helical pattern or coiling of vessels. Coiling of umbilical cord and its blood flow pattern has been the subject of various anatomical and sonographic studies. These studies considered the development, structure of umbilical cord, its blood flow pattern and assessed utility of sonography to detect abnormal coiling and its blood flow pattern in utero as a marker of foetal compromise. This study will be done to determine whether abnormal umbilical cord coiling patterns and its blood flow parameters measured sonographically between 13 to 28 weeks of gestation are associated with adverse perinatal outcomes.
NEED FOR STUDY Very few studies have assessed blood flow characteristics utilizing
Doppler ultrasound and its association with umbilical cord coiling index and
perinatal outcome. we hypothesized that umbilical coiling
index may be associated with abnormal cord blood flow pattern and associated with various perinatal outcome. Hence if the coiling index and its Doppler blood flow characteristics
will
be measured
antenatally, it would act as a predictor
of adverse perinatal
outcome.
RESEARCH QUESTION Can second trimester umbilical coiling index and its doppler flow characteristics be used to predict adverse perinatal outcome? AIM To determine if any association is present between umbilical coiling index and doppler flow parameters in second trimester with adverse perinatal outcomes. HYPOTHESIS There is no association between umbilical coiling index and its doppler parameters measured in second trimester with adverse perinatal outcomes. OBJECTIVES To record umbilical coiling index and doppler flow parameters in second trimester. To find any association between umbilical coiling index and its doppler flow parameters with perinatal outcomes. |
