简要总结
The purpose of this study is to determine whether there is a difference between cortisol levels in fetal blood of babies who were born while using a unipolar needle opposite to using a bipolar needle, and compared to the control group (infants who were born in a vaginal birth).
详细描述
Today, on Caesarean section, there's a widely usage of electric unipolar needle for cutting tissue and / or bipolar needle to burn blood vessels. These Needles use an electric current flow for cutting the tissue. When using unipolar needle there's a transfer of the electric current through the mother's body and through the amniotic fluid , while when using bipolar needle the current goes back through the needle directly the generator so that the flow does not transfer to the amniotic fluid and fetus.
Despite the growing usage of electric needles, there is no literature information about the extent of electrical current that is transferred to the fetus during cutting, hence, no information about stress level felt by the baby as a result of electrical current exposure.
The purpose of this experiment is testing the possibility that there is a difference between cortisol levels in fetal blood of babies who were born while using a unipolar needle opposite to using a bipolar needle, and compared to the control group (infants who were born in a vaginal birth).
Also, we want to check whether there is correlation between maternal cortisol levels and newborn cortisol levels (whether motherly cortisol levels affects newborn cortisol levels).
To assess cortisol at birth, blood will be taken from the umbilical vein following clamping of the cord after birth. Saliva-based cortisol will be collected from mothers.
