Nuchal cords and neonatal outcome.

摘要: To assess the significance of nuchal cords, 110 affected woman-infant pairs at term gestation were compared with control pairs. Newborns a cord had an increased prevalence umbilical artery acidemia (22 versus 13 110; P less than .05) and more variable fetal heart rate (FHR) decelerations in first stage labor (mild = 41 20; .0001; moderate-severe 21 5; .0001) second (moderate-severe 46 21; .0001). In newborns cord, was usually mixed (68%) or respiratory (23%) origin, pure metabolic infrequent (9%). We conclude that cords are associated FHR stages incidence acidemia.
