The birthing procedure is difficult. Babies go through a lot of bodily changes as they get used to life outside the womb. As soon as they leave the womb, they are no longer able to rely on the mother's placenta for essential bodily processes like breathing, digesting, and disposing of waste. All of a baby's body systems must undergo significant change and collaborate differently as soon as they are born. Some infants find it challenging to make these changes. If the child is born before 37 weeks, has a low birth weight, or has a medical problem that needs rapid medical attention, this is more likely to occur. Babies that require special care after delivery are frequently admitted to the neonatal intensive care unit (NICU) of the hospital. The NICU uses cutting-edge technology and teams of various medical specialists to offer specialised treatment for neonates who are having difficulty. Babies who require intensive care may need to be transferred to another hospital because not all of them have NICUs. It can be unexpected for any parent to deliver a premature or ill baby. Anxiety can also be induced by the NICU's unusual sights, sounds, and technology. You may feel more at ease when your child receives care for their unique requirements if you are aware of the procedures that are performed in the NICU. When a newborn has trouble swallowing or has a disease that makes it difficult for them to eat, nutritional help is required. The NICU personnel will feed the infant through an IV or a feeding tube to make sure they continue to receive essential nutrition. In the first few hours in the NICU, not many premature or low-birth-weight newborns can be fed, and many unwell babies are unable to take anything by mouth for several days. The NICU staff starts an IV to give fluids containing water, glucose, sodium, potassium, chloride, calcium, magnesium, and phosphorus Total parenteral nutrition (TPN) is the name for this form of nutrition support (to ensure that your baby is receiving appropriate nutrients). A medical professional will insert an IV into a vein in your infant's skull, wrist, or lower leg. The staff may insert numerous IVs during the first few days because an IV normally lasts less than a day. Most infants eventually require more sustenance than these tiny IV lines can provide. After a few days, the medical team places a catheter—a lengthy IV line—into a bigger vein so your baby may receive more nourishment. For every 2.2 pounds, or 1 kilogramme, of body weight, a baby needs roughly 120 calories per day. A tiny plastic tube inserted through the mouth or nose may first be required to feed a very small newborn. Enteral food stimulates the GI tract to expand and begin working. Do not be reluctant to express your worries or inquire about the processes being carried out. Your anxiety may be reduced if you take an active role in your baby's care. Having friends and family by your side when your child is in the NICU may also be beneficial.
