If patients with rectal cancer want to take good care of them, they must pay attention to the details, because we need to know that patients with rectal cancer need to have a urinary catheter before the surgery, and they may have an artificial anus after the surgery, which are the aspects we need to take care of, and they should also be given certain psychological care according to the specific manifestation of patients with rectal cancer. Catheter care: 1.The catheter is usually left in place for about two weeks, and the urethral opening should be well taken care of. 2. Remove the catheter, train the bladder function from 5 to 7 days after surgery, and open the catheter once every 4 hours to prevent the difficulty of urination. Artificial anus care: 1, artificial anus with clamps or temporarily closed, 2 to 3 days after surgery to be opened after the recovery of intestinal peristalsis. 2, lying position because of the initial defecation thin stool, more frequent, the patient line side lying position. 3, skin care at the beginning of the thin stool, constantly flowing out of the abdominal wall around the skin irritation, easy to cause skin erosion and contamination of the incision, you need to use plastic film paper to separate the incision from the artificial anus, with petroleum jelly gauze around the fistula in a circle, the surrounding skin coated with zinc oxide ointment protection. 4. Change the fecal bag regularly to keep the abdomen clean. 5, training regular defecation: patients should be out of bed for L weeks after surgery and taught how to use the fecal bag, trained to defecate regularly, regular enemas through the fistula to establish the habit of regular defecation. 6, to prevent diarrhea or constipation: patients are prone to diarrhea or constipation after surgery, should pay attention to dietary regulation, into less slag semi-fluid or soft food. When constipation occurs after 3 to 4 days of eating without defecation or due to blockage of fecal mass, a catheter can be inserted, (usually not more than 10CM) and a liquid paraffin oil or soap and water enema is commonly used, but note that the pressure should not be too high to prevent intestinal perforation. To prevent constipation, encourage patients to eat more fresh vegetables and fruits as well as exercise more often. 7, to prevent fistula stenosis: observe whether the patient has edema, ischemia, necrosis at the fistula opening, and dilate the fistula opening with fingers twice a week for 5-10 minutes for 3 months after L weeks after surgery to avoid fistula stenosis.
