Premature Infant Clinical Trials

Many babies born very preterm (\<32 weeks of pregnancy) require support to breathe from a breathing machine (mechanical ventilator) via a breathing tube. Although this keeps babies alive, it can damage their lungs. To reduce this damage, doctors and nurses try to change babies to gentler breathing support that does not require a breathing tube. This is usually done using a method called nasal continuous positive airway pressure (nCPAP) that uses a nosepiece to deliver breaths. This process of removing the breathing tube is called extubation. Many babies will need the breathing tube put back in after extubation (for various reasons) and this is independently associated with poorer outcomes. This research study aims to compare two ways of performing extubation - both of which are already used regularly by doctors and nurses. The standard extubation approach involves taking a baby's breathing tube out first, then applying the nosepiece and starting nCPAP. The more recent approach, called prePAP, involves applying the nosepiece and starting nCPAP before taking the breathing tube out. Previous research suggests that a prePAP approach may provide better support for babies during extubation. However, larger studies are required before this approach is more commonly used. This study is investigating whether extubating the baby with prePAP is better than extubating the baby without prePAP. The main question it aims to answer is: Does initiating nCPAP before extubation in very preterm babies reduce the fall in their oxygen levels post-extubation?
