An Analysis of Pregnancy Outcome in Dichorionic and Monochorionic Twins Given Special Antenatal and Intranatal Care: A Four-Year Survey

摘要

Objective The present study aims to analyze perinatal outcomes in twins given special care during pregnancy and labor and to compare fetal and neonatal outcomes in dichorionic twins with monochorionic twins. Study Design Eighty eight (88) twin pregnancies booked for care at a tertiary care Fetal Medicine centre were included in this study. The maternal demographic variables, course of pregnancy, fetal problems, and specialized fetal therapeutic and diagnostic interventions were noted. The above parameters were compared in the sub-groups of dichorionic and monochorionic twin pregnancies and related to the perinatal outcome. Statistical analysis was done using the student’s t test and the two-tailed chi sqaure tests with Yate’s continuity correction. A p value <0.05 was considered as significant. Results Mean maternal age was 30.34 + 4.81?years (range 19–48). 81?% of the twins were DCDA, and 19?% were MCDA. The mean gestational age at delivery was 34.4?±?3.5?weeks, and this was not significantly different in MCDA and DCDA groups. Serious fetal problems warranting intervention at the time of initial referral were significantly higher in MCDA twins although overall perinatal outcome in both groups were not different. Conclusion Specialized care during pregnancy and labor including active fetal surveillance and therapeutic intervention when indicated improves the perinatal outcome in twin pregnancies and ensured at least one healthy live birth in over 90?% cases, although with an increase in late prematurity.
