Pay attention to straightening the leg on the puncture side for 24 hours, for example, if there is a puncture point in the right femoral artery, the right leg should be straightened for 24 hours, especially for the elderly, patients with abnormal blood coagulation, obese people, patients who have taken drugs such as aspirin and Warfarin, and patients with blood diseases. More attention should be paid to prevent bleeding from the femoral artery and hematoma, which can be life-threatening in cases of severe bleeding. Families should pay close attention to the puncture site for bleeding and hematoma, if there is any, promptly get the doctor to re-pressure bandage. Because of the patient’s urination and defecation, violent coughing, etc., the puncture point of femoral artery should be pressed by hand in advance to prevent local bleeding. 2.Patients who apply platinum chemotherapy drugs, especially cisplatin, after hepatocellular carcinoma intervention should pay attention to hydration for three days, and hydration means to keep the amount of fluid infusion at 2000-3000ml, and pay attention to urination to protect liver and kidney function.
