Abstract

To investigate the physiological role of calcium in the labor process. Eighty-eight term healthy pregnant women who gave birth to normal healthy neonates participated in our study. We compared calcium levels between pregnant women who had normal delivery and those who underwent scheduled cesarean section. The control group consisted of pregnant women with gestation > or =37 weeks without contractions. The groups were compared with respect to calcium levels: (a) in maternal blood serum; (b) in blood serum of the neonates and mothers; and (c) in blood serum between neonates. Significantly higher calcium levels were found in the group of pregnant women who delivered vaginally compared to those who delivered by scheduled cesarean section and those of the control group. We assume that the increased calcium levels during the first stage of labor are involved with a possible role of calcium in the mechanism of initiation of labor.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
