Antenatal Dexamethasone for Late Preterm Deliveries

Preterm Birth Clinical Trial

Official title: Antenatal Dexamethasone for Late Preterm Deliveries: a Randomized Controlled Trial

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to compare dexamethasone in late preterm deliveries. The main questions it aims to answer are: Does antenatal dexamethasone reduce the need for respiratory support in late preterm infants? Does antenatal dexamethasone reduce neonatal morbidities and mortality? Does antenatal dexamethasone reduce admission to Neonatal Intensive Care Unit and length of hospital stay? Participants will be allocated into 2 groups: intervention with dexamethasone IM and control (standard care). Investigators will compare these two groups to see if antenatal dexamethasone reduces the need for respiratory support in late preterm infants, neonatal morbidities and mortality, admission to NICU and length of hospital stay.

Clinical Trial Description

Study design: The study is a double-blinded randomized controlled trial, parallel group. The sequence of randomization will be generated by using an online tool (https://www.sealedenvelope.com/simple-randomiser/v1/lists) with 2 groups of treatments with ratio 1:1, block of variable size (2,4,6), list length 302, no stratification. After having a randomization sequence, the symbol of group (control or intervention) will be kept in a sealed envelope. These envelops will be also put in the order as the allocation sequence. Assessors and investigators will be blinded to the group allocation. Participants: Participants are women with singleton pregnancy, from 18 to 45 years old, at 34+0/7 to 36+6/7 weeks of gestation and at high risk for delivery during the late preterm period in the next 7 days. Intervention: Antenatal dexamethasone. Participants in the intervention group will be given a course of four intramuscular injections of dexamethasone 6 mg (1.2 milliliter), 12 hours apart. Comparison: Standard care. Outcomes: Primary outcome: Need for any respiratory support in first 72 hours, which is determined when babies need to be supported with continuous positive airway pressure (CPAP), high-flow nasal cannula (HFNC), supplemental oxygen, or mechanical ventilation in first 72 hours to keep the saturation in a proper range (90-95%). Sample size is 300 participants in 2 groups: intervention group and control group. Place: The study will be conducted at Danang Hospital for Women and Children, Danang, Vietnam. Eligibility of participants will be assessed at admission area of delivery department. One senior obstetrician will introduce the study to the patient by using the study information sheet. If the pregnant woman agrees to join in the research, the writen consent will be delivered to her and she will sign on it. When participants agrees, one sealed envelope with a number inside will be opened to allocate which group she involves. At that time, Eligibility criteria and Part 1 of the CRF will also be filled. After randomization, pregnant women will be monitored at delivery rooms until delivery or c-section. After birth, both mother and baby will be closed monitored and assessed until transferred to post-natal wards or neonatal unit. Part 2. Labour and at birth Part 3. Newborn outcomes Part 4: Maternal outcomes will be collected. If infants discharge before 28 days old, the follow-up section will be done at follow-up clinic of neonatal unit. Information about outcome (alive or death), any re-admission to hospital (number of time and reasons), and nutrition (types of milk (breast milk, formula milk or mix), feeding methods (breast feeding, bottle, tube/cup/spoon) will be collected for Part 5 of CRF. ;
