I would read up on neonatal cardiology and have a good understanding of a neonate's normal vitals as well as affects of common conditions and etiologies upon those vitals. Moreover, I would have a keen understanding of what you learned during the NRP part of your Paramedic curriculum. With regard to research, I suggest reading up on a few case studies in infant and neonatal critical care.
During my paramedic rotations, I focused on case studies and drug dosages. (It never hurts to have Epocrates Mobile on your side).
What textbook are you using? Mosby's Paramedic Textboook, Essentials of Paramedic Care, Emergency Care in the Streets, or Brady's?
