LC surgery is laparoscopic cholecystectomy. In general surgery, gallbladder stones and cholecystitis are a common and benign disease, and laparoscopic cholecystectomy is used for a large number of patients. After returning from the surgery, the patient needs to be put on oxygen and cardiac monitoring immediately after entering the hospital room, observing the patient’s vital signs, monitoring the heart rate, blood pressure and pulse rate. At the same time, it is necessary to observe the patient’s degree of awakening from anesthesia, whether there is complete awakening, whether there will be nausea, vomiting, and aspiration. Secondly, the patient’s temperature and abdominal pain should be observed every day in the following days, and if there is an abdominal drain, the color of the drain should be observed, whether it is bloody, pale blood, or bile-like, as well as the amount of drainage from the drain. Depending on the color of the drainage as well as the amount, the next step in continuing treatment may be necessary.
