Hepatic ascites can only come out up to 3,000 ml a day, and the first drainage after laparotomy should not be more than 1,000 ml. This is because if excessive release of hepatic ascites, it is easy to have blood volume insufficiency, water-electrolyte balance is damaged, and in serious cases, it will lead to hepatic encephalopathy, which will jeopardize the patient’s life safety. Therefore, attention should be paid to the water-electrolyte balance when releasing hepatic ascites, and electrolyte disorders should be corrected and albumin supplemented when necessary. Generally, the first abdominal puncture to release ascites is not more than 1000mL, and then the amount can be increased according to the situation, but the maximum is not more than 3000mL. After the release of hepatic ascites, it is necessary to closely observe whether the patient’s face is pale, whether there is dizziness, pay attention to the blood pressure and heart rate monitoring, to determine whether the patient appears to be hypovolemic, and at the same time, it is necessary to pay attention to the rechecking of sodium ions and potassium ions, because excessive release of hepatic ascites can cause water electrolyte disorders. Patients with hepatic ascites, should follow the doctor’s instructions to standardize treatment.
