[0002] Gastrointestinal fistula is one of the serious complications of abdominal surgery. Its main feature is that a large amount of corrosive digestive fluid overflows through the fistula, which not only causes the loss of body fluids and nutrients, disrupts the physiological function of the body, and causes nutritional imbalance, but more importantly, causes edema, erosion and necrosis of the tissue at the fistula, and the wound is difficult to heal, endangering the patient's life. Adequate drainage is an important means of treating gastrointestinal fistula, and active and effective nursing measures are the key to keeping the drainage tube unobstructed and ensuring the drainage effect. At present, the clinical use of continuous flushing negative pressure drainage is simple to make, economical and effective, and has important clinical significance for the prevention and treatment of postoperative intestinal fistula, bleeding, bile leakage and infection in abdominal surgery.
