Patient: Sudden onset of epigastric pain with chest tightness for 8 days. 2011 August 4, 2011, he was admitted to Changhai Hospital. 2011 August 5, the operation name: ascending aorta + total arch replacement + descending aorta stent placement. 2011 September 1, he was discharged from the hospital. Blood biochemistry showed that albumin was 30, electrolytes were normal, and blood count was normal: HB95. He was discharged from the local hospital after two days of cefuroxime (Taiwan) infusion without improvement (the local hospital refused to accept this patient). The patient complained of itchy skin all over the body and denied various skin diseases and hygiene problems. I would like to ask Prof. Song about the treatment. Thank you.
