Evaluation on the Influence of the Timing of Twin Pregnancy Termination on the Outcome of Mother and Infants

Abstract

Objective: To observe the maternal and infant outcomes of pregnant women with twins terminating their pregnancy at different timings.  Methods: Among the twin pregnant women admitted to our hospital from August 2019 to August 2020, 50 primiparous women who opted to terminate their pregnancies at 5 different timings of “34——34⁺⁶ weeks”, “35——35⁺⁶ weeks”, “36——36⁺⁶ weeks”, “37——37⁺⁶ weeks”, “38——38⁺⁶ weeks” were selected as the research subjects. According to the timing of pregnancy termination, they were divided into 5 groups, each with 10 cases of pregnant women, and the impact of the timing of pregnancy termination on the outcome of the mothers and infants were compared.  Results: The “37——37⁺⁶ weeks” group had the largest amount of postpartum hemorrhage, and the difference in Hb level before and after delivery was the largest. With the increase in gestational week, the weight of both large and small fetuses increased. In terms of neonatal diseases, the comparison between “34——34⁺⁶ weeks”, “35——35⁺⁶ weeks”, “36——36⁺⁶ weeks” and “37——37⁺⁶ weeks”, “38——38⁺⁶ weeks”, P＜0.05, the comparison between “37——37⁺⁶ weeks” and “38——38⁺⁶ weeks”, P>0.05.  Conclusion: The extension of the gestational week of twin pregnancies has no effect on postpartum hemorrhage, but it can improve the outcome of infants.
