If a newborn has intestinal obstruction, conservative therapy and surgical treatment can be used, as follows: 1. Conservative therapy: If the symptoms of intestinal obstruction in newborns are relatively mild, and there is no obvious vomiting, abdominal distension, etc. You can apply the open plug or other laxative drugs, such as hemp seed pills, etc., so that the newborn can have a smooth stool, the intestinal obstruction will be effectively relieved, and the newborn can be spared from the pain of surgery; 2. Surgical treatment: If the symptoms of intestinal obstruction in newborns are heavy, abdominal distension is particularly serious, vomiting is violent, and even bile is vomited, and the mental state is also poor, timely surgical treatment should be performed. Otherwise, the aggravation of intestinal obstruction in newborns will lead to necrosis of the intestine, as well as serious infection of the whole body, which can be life-threatening in serious cases. In this case, conservative treatment cannot be used, and timely surgical treatment is required.
