Twin pregnancy: prematurity and perinatal mortality

Area of Science:

• Obstetrics and Gynecology
• Perinatology
• Maternal-Fetal Medicine

Background:

• Twin pregnancies present unique challenges in perinatal care.
• High rates of preterm labor and associated perinatal mortality are observed in twin gestations.
• Effective management strategies for twin pregnancies are crucial for improving outcomes.

Purpose of the Study:

• To analyze the management and outcomes of twin pregnancies.
• To evaluate the effectiveness of bed rest in improving perinatal outcomes for twin pregnancies.
• To determine the optimal gestational window for implementing bed rest interventions.

Main Methods:

• Retrospective analysis of 245 twin pregnancies.
• Data collected over an 8-year period (1976-1984).
• Examination of perinatal mortality rates and gestational age at delivery.

Main Results:

• The incidence of twin delivery was 1 in 69.
• Perinatal mortality rate was 85.7 per 1,000 total births.
• A significant proportion of perinatal deaths (28 out of 42) were linked to preterm labor before 28 weeks' gestation.

Conclusions:

• Hospital bed rest for twin pregnancies should be implemented between 21 and 28 weeks' gestation.
• There is no clear theoretical or observed benefit for hospitalization beyond 28 weeks' gestation for twin pregnancies.
• Targeted interventions during the critical window of 21-28 weeks may improve perinatal outcomes in twin gestations.
