After ascites puncture, the patient should lie down and rest for 8 to 12 hours, and continue to observe whether there is any adverse reaction and whether there is any overflow of fluid at the puncture point. Peritoneal fluid is extracted from the peritoneal cavity by puncturing the peritoneal cavity directly through the anterior abdominal wall with a puncture needle or catheter. In order to avoid oozing of fluid from the puncture hole, the patient should lie down and rest for 8 to 12 hours after the peritoneal fluid puncture and keep the puncture hole on the upper side in order to avoid the leakage of peritoneal fluid, and continue to observe whether there are any adverse effects such as dizziness, palpitations (accelerated heartbeat, often accompanied with panic), nausea, shortness of breath, and so on, in order to be alert of the triggering of hepatic encephalopathy. If after ascites puncture, the puncture site needs to be covered with gauze and then bandaged for fixation. If there is any ascites spillage, the physician should be informed in time, and it can be viewed by the medical staff and then applied with fire cotton glue, and the dressing can be changed in time to prevent the wound from becoming infected. If there is a possibility of infection, it can be treated with antibiotics such as cefuroxime and levofloxacin.
