Four prohibitions: 1, fasting: acute abdominal disease lesions in the abdominal organs, so that the gastrointestinal tract can not complete the body’s digestive function. If eating will aggravate the inflammation of the abdominal cavity and fluid exudation, or aggravate the obstruction, vomiting and the occurrence of postoperative intestinal distension. 2, disable painkillers: patients with acute abdominal disease before the diagnosis of painkillers are prohibited, otherwise it will cover up the condition, leading to misdiagnosis and loss of time to rescue. 3, prohibit laxatives and enemas: laxatives or enemas can stimulate the intestinal wall, increase intestinal peristalsis, so that the intestinal cavity pressure increases, which can cause intestinal rupture and inflammation spread, resulting in acute peritonitis, intestinal fistula and aggravate the condition. 4, prohibit hot compresses: hot compresses can reduce pain and cover up symptoms. If the organ bleeding or various traumatic bleeding, hot compresses can make the blood vessels dilate and aggravate the bleeding. Four anti: 1, anti-shock: the main cause of shock is blood loss, infection and trauma caused by a sharp decrease in effective circulating blood volume, decreased cardiac blood expulsion, microcirculatory blockage, poor tissue perfusion and cellular hypoxia caused by. Therefore, we should closely observe the changes in the condition and take timely and effective measures to prevent the occurrence of shock. 2, anti-infection: acute abdominal disease are accompanied by infection, and most of them are E. coli infection. Pre-operative skin preparation should be done carefully to reduce the chance of infection. Postoperatively, because of the long time can not eat, gastrointestinal distension, wound pain, decreased body resistance, poor healing of the anastomosis, in addition to the spread of abdominal inflammation, and easy to lead to systemic infection and its complications, such as pneumonia, sepsis, etc.. Therefore, postoperative anti-infection is still very important and must be treated with effective antibiotics. Pay attention to dressing change and semi-recumbent position after waking up; strengthen oral care and prevention of decubitus ulcer care; encourage and assist in coughing to reduce the occurrence of pulmonary complications. 3, anti-electrolyte disorders: due to preoperative vomiting and gastrointestinal decompression and other reasons caused by the loss of digestive and body fluids in patients with acute abdomen, postoperative due to fasting and gastrointestinal decompression, coupled with trauma, blood loss, infection, reduced digestive function, impaired liver cell function and other reasons, easy to cause electrolyte disorders. Patients with large amount of gastrointestinal fluid loss are mostly seen with hyponatremia and hypokalemia. According to the results of biochemical examination and blood gas analysis, the lost components should be replenished in time, paying special attention to the principle of potassium replenishment and rationalizing the time and order of medication to maintain the balance of water and electrolytes. 4, anti-distension: abdominal distension is a common postoperative symptom in patients with acute abdomen, mostly caused by acute gastric dilatation, gastrointestinal motility inhibition and low blood potassium, etc. Generally, patients appear “gas and distension” within 2~3 days after surgery. The treatment of gastrointestinal distension after abdominal surgery focuses on prevention. Attention should be paid to preoperative fasting, gastrointestinal decompression, and correction of water-electrolyte disorders. Special attention should be paid to keep the gastrointestinal decompression open to avoid the lumen being obstructed by intestinal contents and so on. After eating, you can take some apples, orange water and juice lotion, which can help digestion and promote appetite, and also can supplement potassium to reduce abdominal distension.
