Neonatal surgery refers to surgeries performed on newborns, while foetal surgery refers to operations performed on babies still in the womb. These procedures cover a wide range of treatments and are commonly employed to correct a variety of birth abnormalities. Neonatal surgery is done on babies that have birth abnormalities that can't be corrected while they're still in the womb. Surgery might be performed right after birth or in the days or weeks afterward. Fetal and neonatal surgery are both extremely difficult and often fatal operations that require a multidisciplinary team of doctors. They can, however, be lifesaving. Both foetal and neonatal surgery are treatments for a wide range of birth abnormalities and other illnesses. Infants who require newborn surgery or cardiology services, as well as those who require therapeutic cooling, are admitted to a neonatal intensive care unit (NICU). Premature babies frequently require neonatal surgery to fix developmental issues.
