What else should we do before we get a liver needle?

In order to make the examination safer, routine liver biochemical examination, coagulation function test, blood routine, platelet test, chest X-ray and abdominal ultrasound should be performed 1 to 2 days before surgery. 1 day before the operation, ultrasound should be used to locate the puncture site and find out if there are any large blood vessels or enlarged gallbladder. Preoperative 1 and the day of surgery, to intramuscular injection of vitamin K1 10 mg each 1 times, the patient had better be hospitalized. Before surgery, the doctor should explain to the patient the precautions to cooperate with the puncture, practice the aspiration and eliminate the patient's fear and tension. The patient's blood pressure and pulse were measured half an hour before the operation and urine was emptied. After liver puncture, blood pressure and pulse should be closely observed, and absolute bed rest for 24 hours after surgery. Patients can get up for indoor activities after 24 hours in bed.
