The main items that need to be checked after the birth of a newborn baby include measurement of height and weight, blood routine, heart and lung auscultation, hearing test and other tests. 1. Height and weight: The height and weight of the fetus should be measured routinely after birth to understand the growth and development of the fetus. 2. Blood routine: Blood routine is also needed to observe whether the fetus has anemia. 3. Auscultation of the heart and lungs: to see if there is any murmur in the heart and lungs, to rule out congenital heart disease and lung malformation. 4. Hearing test: three days after birth, the hearing should be tested to observe whether there is any congenital hearing impairment. In addition to this, it is important to observe whether there are any abnormalities in appearance, such as congenital anal atresia. Newborns are routinely examined after birth to prevent the appearance of a number of diseases. In case of any other problems, it is advisable to consult a medical professional for guidance.
