After informed consent is obtained, babies are randomly assigned (from sealed, opaque, consecutively numbered envelopes), to the "ETT" or "LMA". The "ETT" group is managed according to our current practice of surfactant therapy (endotracheal intubation following premedication with atropine + morphine), whereas the "LMA" group will be pre-medicated with atropine before LMA insertion for surfactant administration.
