General Obstetrics and Gynecology: ObstetricsNeonatal mortality and morbidity rates in term twins with advancing gestational age
Section snippets
Material and methods
A population-based retrospective cohort study was carried out with twin registry data (1995-1997) from the United States using the Matched Multiple Birth File created by the Centers for Disease Control and Prevention. Sets of multiple births in the 1995 through 1997 birth files were matched by plurality, state and country of occurrence of delivery, mother's date of birth, date of last menstrual period, number of prenatal visits, level of education, weight gain during pregnancy, and date of
Results
There were 152,233 twin pairs in the database. Of which, 18,689 twin pairs were excluded because of a missing value on birth order, and 2480 pairs were excluded because of a missing value or apparent coding error (first twin cesarean delivery but second twin vaginal delivery) on mode of delivery. There were 70,621 twins excluded because they were delivered at <37 completed weeks of gestation, which left 60,443 twin pairs for analysis.
From Table I, it can be seen that a significant difference
Comment
There was an increased incidence of total neonatal and noncongenital anomaly-related deaths in the ≥40 weeks of gestation group when compared with the 37 weeks of gestation group for both twin A and B. When morbidity was examined, there was an increased risk of having a low Apgar score for the ≥40 weeks of gestation group for both twin A and B. In regards to the need of assisted ventilation, there was a decreased risk in the 38 and 39 weeks of gestation group for twin A and a decreased risk in

2020, Clinics in PerinatologyCitation Excerpt :In a study by Soucie and colleagues71 (2006) it was found that the risk of neonatal respiratory complications requiring ventilatory support decreases after 38 weeks. This study also identified significant risk of neonatal death with DCDA pregnancies extending after 40 weeks.71 A randomized controlled trial of uncomplicated twin pregnancies (including both monochorionic and dichorionic gestations) comparing delivery at 37 versus 38 weeks noted no difference in composite adverse infant outcomes.72
