Patients who are hospitalized for colorectal cancer surgery are generally nervous during their hospitalization.
It is necessary to have relevant examinations from the beginning of hospitalization, and if the indicators are not qualified, the operation cannot be performed immediately.
1.Blood tests are done, and anemia or hypoproteinemia should be corrected.
2.CT or ultrasonography of the liver is routinely done for liver metastases.
3.If the patient has urine disease, blood glucose should be kept within the basic normal range.
4.Patients with cardiopulmonary and renal insufficiency should be treated aggressively.
5.Bowel preparation: The purpose of bowel preparation before colorectal surgery is to remove stool, reduce the number of bacteria in the intestine, remove local infection, and prevent complications such as postoperative infection. This can usually be done in two ways:
Reducing potential sources of contamination visible to the naked eye by mechanically cleaning the solid matter in the intestinal lumen is called mechanical preparation;
Inhibition of bacteria attached to the surface of the intestinal mucosa and mucus by oral non-absorbable antibiotics is called antibiotic preparation.
6.**Preparation: Before the operation, **cleaning should be done to remove the perianal and **hair, so as to facilitate the surgical operation.
7.Indwelling gastric and urinary tubes are placed preoperatively.
8.The anesthesia induction phase begins with intravenous administration of medium- and long-acting broad-spectrum antibiotics.
9.Informed consent should be signed before surgery: patients and families need to be aware of the risks, complications, and other conditions of the procedure.
