Surgery in the elderly is relatively risky because many patients have underlying medical conditions, including hypertensive disease, diabetes, coronary artery disease, and chronic obstructive pulmonary disease. The perioperative period is prone to complications that increase the difficulty of surgical treatment and the difficulty of perioperative management. Common risks are intraoperative and postoperative cardiovascular and cerebrovascular accidents, and complications such as sudden cardiac death, heart attack, or cerebral thrombosis or cerebral hemorrhage. In addition, if the elderly are bedridden for a long time after surgery, it is not convenient to move around, but also easy to complicate intrapulmonary infection and urinary tract infection. Especially for patients with long time indwelling urinary catheter, it is also easy to induce serious infectious shock. In addition, the relative poor nutritional status of the elderly, the postoperative incision is slow to heal, and it is also easy to show delayed healing of the incision, and if necessary, it is necessary to promote healing through multiple drug changes.
