What is a Catheter and Why is it Used in Neonates?
A catheter is a thin, flexible tube that can be inserted into a vein or body cavity to deliver fluids, medications, or to remove fluids. In neonates, catheters are often essential for administering intravenous (IV) fluids, medications, and nutrients, especially in the case of premature infants or those with severe neonatal disorders like congenital heart defects, respiratory distress syndrome, or sepsis.
