Effects of ACS in Twin With LPB: Study Protocol for a RCT
- Conditions
- Twin Pregnancy, Antepartum Condition or Complication
- Interventions
- Drug: Normal saline
- Registration Number
- NCT03547791
- Lead Sponsor
- Seoul National University Hospital
- Brief Summary
This study will be the first study that evaluates the effectiveness of antenatal corticosteroid (ACS) in late preterm twin neonates.
- Detailed Description
Antenatal corticosteroid (ACS) has been proven to prevent adverse outcomes including respiratory morbidities in preterm neonates before 34 weeks of gestations. Recently, it has been suggested that ACS may be also effective for reduction of respiratory complications in singleton late preterm pregnancies. On the contrary, there is a paucity of information regarding the effectiveness of ACS in twin neonates with late preterm birth, and nowadays guidelines are recommending the use of ACS in twin pregnancies based on the evidences in singleton pregnancies. However, the effect of ACS in twin needs to be determined, because the rate of neonatal morbidities in twin preterm neonates seems to be different from that in singleton neonates. This study aims to determine the effectiveness of ACS in late preterm twin neonates.

- (2) Lethal major fetal anomaly, fetal distress or fetal death in utero
- (3) Expected to deliver within 12 hours; for example, advanced cervical dilatation (>8cm) in preterm labor or active phase labor (cervical dilatation>4cm) in preterm premature rupture of membranes
- (4) History of a previous administration of ACS before 34weeks of gestation for fetal lung maturation
- (5) Administration of systemic steroid for medical indications
- (6)Diagnosis of clinical chorioamnionitis Fever >37.8 and the presence of two more following conditions: uterine tenderness, foul-odored vaginal discharge, maternal leukocytosis(>1500), maternal tachycardia(>100) or fetal tachycardia(>160)

Respiratory distress syndrome 72 hours after birth Presence of clinical signs of respiratory distress (tachypnea, retractions, flaring, grunting, or cyanosis), with a requirement for supplemental oxygen with a fraction of inspired oxygen of more than 0.21 and a chest radiograph showing hypoaeration and reticulogranular infiltrates
Surfactant use 28 days after birth Surfactant use
Maternal complication 72 hours after birth Chorioamnionitis and Postpartum endometritis
Need for resuscitation at birth at birth any intervention in the first 30 minutes other than blow-by oxygen
