Rebound pain in the lower abdomen is most often seen when intra-abdominal organ lesions involve the adjacent peritoneum and also in primary peritonitis. Rebound pain is a sign of inflammatory involvement of the peritoneal wall and is most often seen in cases of intra-abdominal organ disease involving the adjacent peritoneum and primary peritonitis. Gently pressing on the painful area, then quickly lifting the hand, and having a distinct pain at the moment of lifting the hand, is called rebound pain, which often represents inflammation of the peritoneum where the pressure is applied. So, how can patients prevent the emergence of abdominal rebound pain? The following is a brief introduction: 1, rebound pain: is a sign of inflammatory involvement of the peritoneal wall layer, first of all, to establish the concept of asepsis: abdominal dialysis is the patient’s own treatment operations, need to strengthen the abdominal dialysis process of aseptic operation techniques. Usually, each center provides training on the seven-step lavage procedure and fluid exchange for newly admitted patients. Despite the knowledge of relevant aseptic concepts, it is still necessary for the patients themselves to perform strictly in the long-term fluid exchange operation, neglecting any of the steps has the potential risk of infection. 2. Avoid constipation and intestinal infections: constipation and diarrhea caused by improper diet can lead to the transfer of intestinal microbial infiltration to the peritoneum, resulting in peritonitis. Therefore, patients should pay attention to dietary hygiene, avoid overeating and the use of spicy food, try to eat more food containing high fiber such as vegetables, corn, buckwheat, etc.. Try to maintain good bowel habits and take medications to increase bowel movements or laxatives if necessary. Moderate exercise is also good for increasing the peristaltic function of the stomach and intestines. If the patient has diarrhea and other symptoms should be given full attention, timely treatment to avoid intestinal infection and peritoneum. 3, strengthen the catheter outlet care and personal hygiene: it is recommended that abdominal dialysis patients daily care of the outlet of the abdominal dialysis catheter, care should not forcibly remove the outlet crust, pay attention to the protection of the outlet when showering, try to avoid the occurrence of infection and tunnelitis at the outlet. Antibiotic treatment should be administered promptly in case of infection at the relevant site. Patients are advised to bathe and wash their heads regularly to maintain personal hygiene. 4, maintain a good home environment: daily air disinfection should be carried out, air conditioning vents should be cleaned regularly, avoid keeping pets at home, abdominal dialysis fluid exchange location should be away from the wind and windows. 5, nutritional status: good nutritional status is conducive to the maintenance of normal immune function, abdominal dialysis patients because of the daily loss of albumin from the abdominal dialysis fluid, usually need to eat protein as a supplement, the recommended daily protein intake is 1.3 g/kg / day, of which at least 50% is high-quality protein.
