What do you suggest if my newborn is infected "alveolar rupture complication"." pneumopericardium",the doctor said. how to treat it?

Treatment varies: Your lungs are little bunches or air sacks - one of these popped open on your newborn and air escaped where it shouldn't have. How it's treated depends on how big the air leak was. If big, sometimes needs a tube put in chest to remove the air. If small, which most are, can often just watch baby very closely and body will take care of it on its own. Baby needs very close monitoring in the meantime.
