Postoperative renal failure after cerebral hemorrhage can be dialyzed, but adjustment of the anticoagulation regimen needs to be considered. Renal failure reaches a certain level that may require consideration of dialysis, such as in cases of high blood creatinine, heart failure, pulmonary edema, and hyperkalemia. Patients on dialysis still need to be given dialysis even if they have a combined cerebral hemorrhage. Cerebral hemorrhage surgery is not a contraindication to dialysis for renal failure. However, dialysis requires anticoagulation with drugs such as heparin or low molecular heparin, which may aggravate bleeding. Therefore, in order to reduce the number of patients with renal failure after cerebral hemorrhage surgery, the anticoagulation regimen needs to be adjusted if dialysis is needed, such as using heparin-free or citrate anticoagulation. It is recommended that patients with postoperative renal failure after cerebral hemorrhage who need dialysis should go to the hospital in time to make dialysis and anticoagulation plan under the guidance of professional doctors.
