CRRT refers to Continuous Renal Replacement Therapy, which is an acronym for Continuous Renal Replacement Therapy, and is primarily a form of blood purification therapy. It is performed continuously for many hours or close to 24 hours per day to relieve the stress on kidney metabolism, purification and reduce the burden on the organ. This technology works by mimicking the filtration function of the glomerulus, using a semi-permeable membrane filter to help remove water and solutes from the blood, and separating the substances that the body needs from the waste substances that are metabolized, and feeding the body the substances it needs to maintain electrolyte balance and normal functioning of the body. Along with blood filtration, it can also help eliminate inflammatory mediators in the blood, improve the patient’s physical condition, reduce the chances of infection and concurrent inflammation, and improve the function of the autoimmune system, while regular blood purification can maintain the patient’s overall physical condition. It is mainly used for severe kidney, liver, heart and other organ diseases, such as acute renal failure, uremia, hepatic encephalopathy, acute pancreatitis, congestive heart failure, etc. It can reduce the burden of organs and maintain the function of organs. It can also be used to treat autoimmune system diseases, such as sepsis and systemic inflammatory response syndrome, to help inflammatory factors to be excreted from the body in order to reduce the damage of the disease to the organs. In addition, since anticoagulants are required during treatment, they should be administered by a medical professional, and if you feel unwell, please inform your health care provider immediately.
