A small amount of pericardial effusion in a newborn does not usually require special treatment, but a heart ultrasound can be used to rule out congenital heart disease and prevent a missed diagnosis.
A small amount of pericardial effusion in a newborn is usually not serious because a small amount of pericardial effusion can provide lubrication. If there is no recent exposure to cold or malnutrition, no special treatment is needed. Cardiac ultrasound can also be performed to rule out the possibility of congenital heart disease.
However, if the neonate shows signs of infection such as fever, the possibility of pericarditis needs to be guarded against. Liver insufficiency may also cause a small amount of pericardial effusion. In this case, blood can be drawn to check whether the liver function index is normal or not, if the pericardial effusion increases further, it is necessary to treat the cause of the disease under the guidance of the doctor, and if necessary, perform a pericardiocentesis.
Generally speaking, a small amount of pericardial effusion in newborns is not serious, so parents do not need to worry too much. However, it is important to keep the newborn warm and avoid infections.
