The causes of increased abdominal pressure in patients are mainly the following clinical situations: First, in patients with hepatitis B cirrhosis loss of compensation, due to a significant decrease in the ability of the liver to secrete albumin, patients will develop hypoproteinemia, the vascular colloid osmotic pressure drops significantly, the water in the blood vessels can seep into the abdominal cavity, thus causing a large amount of fluid in the abdominal cavity, resulting in abdominal hypertension. At this time, it is necessary to actively supplement human albumin to strengthen diuresis and promote the excretion of fluid in the abdominal cavity, which can reduce the symptoms of abdominal distension. Second, during pregnancy, with the gradual increase in the size of the fetus will cause the patient’s abdomen to expand significantly, which will also cause a significant increase in abdominal pressure. After the fetus is delivered, the pressure in the abdomen can return to normal. Third, acute necrotizing pancreatitis, due to the large amount of pancreatic fluid infiltration into the abdominal cavity, can cause serious infection, can cause abdominal septal syndrome, serious abdominal hypertension endanger the lives of patients.
