The most important aspects of care after hepatectomy include several aspects: 1, postoperative vital signs monitoring, vital signs refer to blood pressure, body temperature, pulse, must be within the normal physiological range. If there is a drop in blood pressure or an increase in heart rate, it means that there is bleeding in the intraoperative surgical field or other conditions, such as insufficient rehydration, which is an important monitoring method; 2. observation of urine volume, the observation of urine volume is of great significance, indicating whether the amount of rehydration is enough, if not enough urine volume will decrease, or even less than 500 ml of urine volume a day suggests that the amount of rehydration is obviously insufficient. If the amount of rehydration is enough, the normal amount of fluid for each person is 2500-3000 ml, but the urine volume is still small, indicating that the surgical field of view may have active bleeding or loss of fluid in the body; 3, pay attention to the post-operative activities of especially elderly patients, post-operative activities advocate early on the bed activities, which can reduce the length of hospitalization and speed up recovery. But there is another problem is that if the surgery is relatively large, elderly and frail patients should not be forced; 4, lung infection, pay attention to the patient’s sputum, pay attention to assist the patient to drain sputum or even use drugs to control lung infection is also very critical; 5, liver function monitoring after surgery, liver function resection surgery is the most common complications, especially the combination of patients with cirrhosis will appear liver failure, liver failure is also very important to have liver failure The care and monitoring of liver function failure is also very important.
