After surgery, the manifestation of significant abdominal distension and lack of ventilation is most often caused by disturbances in the internal environment, especially hypokalemia. The discomfort caused by hypokalemia can be significantly relieved by timely liver and kidney function measurements, intravenous supplementation with polarizing fluids, and intravenous administration of glucose, insulin, and potassium chloride. Also appropriate clockwise abdominal massage and hot compresses can improve microcirculation and assist ventilation. In addition, if the symptoms of abdominal infection are severe, paralytic intestinal obstruction is also likely to be complicated, and intravenous anti-infection treatment should be actively administered, preferably with bacteriological evidence, and the patient should be advised to leave bed early to promote early recovery of intestinal peristaltic function. In addition, abdominal drainage should be left in place in patients with severe infection to facilitate observation of changes in the condition and drainage of purulent or purulent blood.
