Preterm Birth
Conditions
Brief summary
Research Objectives: 1. Establish a prediction and scoring system for twin premature birth. 2. To investigate the curative effect of 200mg,400mg and 600mg of vaginal progesterone in the prevention of twin premature birth. 3. To investigate the effect of stress cervical ligation in preventing premature delivery of twins. 4. The optimal dose of atosiban for the treatment of twin premature birth. 5. The influence of delivery mode on twin premature infants under 32 weeks.

To investigate the effect of stress cervical ligation in preventing premature delivery of twins. 4. The optimal dose of atosiban for the treatment of twin premature birth. 5. The influence of delivery mode on twin premature infants under 32 weeks. It has now entered the second phase: clinical data collection
Interventions
The delivery outcomes of the three groups were compared, including the rate of premature delivery (\<37 weeks of gestation), the rate of early premature delivery (\<32 weeks of gestation), and the need for anti-tocolysis treatment. Rates of premature rupture of membranes (\<37 weeks), neonatal perinatal mortality and morbidity.
