The effects of twin pregnancy on uterine pull tension
摘要
Abstract
Objective To study the effects of the uterine contraction when the uterine pull tension of twin pregnan-cy has changed. Methods The uterine smooth muscle of single and twin pregnant women in the second trimester of pregnancy (26 ± 6) W and late pregnancy(37 ± 6) W were collected to be made into 30 strips each group, ob-served the change of uterine pull tension of single and twin pregnancy and the effects to uterine contraction, when oxytocin concentration gradient was stimulated. Results In Krebs solution, the uterine pull tension of late single pregnancy was bigger than that in the second trimester, and the uterine pull tension of late twin pregnancy was big-ger than that in the second trimester, and the uterine pull tension of the second trimester of twin pregnancy was big-ger than that of single pregnancy at the same time, and the uterine pull tension of late twin pregnancy was bigger than that of single pregnancy at the same time. There was statistical significance (P<0. 05). With the progress of pregnancy, the uterine pull tension was enlarged. Moreover, the uterine contraction of late single pregnancy caused by the change of uterine pull tension was more obvious than that of late twin pregnancy under the oxytocin concen-tration gradient. There was statistical significance (P<0. 05). Conclusion The uterine contraction begins to de-cline with the uterine pull tension of twin pregnancy increases.关键词
