    【Abstract】 Objective To study the effect of umbilical vein-to-vein distance and the index of umbilical cord trosion on the prognosis of perinatal fetal.Methods From April2000to October2001，two hundred and eleven cases of in-patient delivery were recruited.The umbilical cord was clamped and the arterial blood was sampled for blood gas analysis as soon as the child was delivered.At the same time the circuits of cord torsion and the length of umbilical cord were recorded as well as the Apgar score of the neonate and the character of amniotic fluid.Results The umbilical arteˉrial blood’s pH and oxygen pressure were significant different in those with≤2cm umbilical vein-to-vein distance from those with>2cm vein-to-vein distance(P<0.05).The distance of the umbilical vein-to-vein had positive correlation with the umbilical arterial blood’s pH ......
