Whether or not kidney failure caused by hemorrhagic fever can be saved depends on the specific situation, usually timely detection, early treatment can be saved, but also related to the patient’s own physical condition. Renal failure due to hemorrhagic fever may be related to insufficient renal perfusion, renal interstitial edema compression and other reasons, it is recommended to seek timely medical treatment. 1. Insufficient renal perfusion: Decrease in blood pressure can lead to a decrease in the pressure of renal perfusion, causing insufficient renal perfusion, such as shock, can cause hemorrhagic fever renal failure. Such patients can follow the doctor’s instructions to use injectable dopamine hydrochloride and other drugs to treat, and supplement blood volume, oliguria can use diuretic drugs; polyuria attention to replenish fluids and electrolytes. 2. Renal interstitial edema compression: renal interstitial edema compression of renal tubules, as well as a large number of protein tubular obstruction of renal tubules, inducing renal tubular epithelial cell damage, necrosis, resulting in hemorrhagic fever renal failure, manifested as oliguria, anuria and other symptoms. When diuretic medication is not effective, or when the condition is severe such as hyperkalemia, hemodialysis treatment may be performed. Patients with hemorrhagic fever may be combined with coagulation and cardiac insufficiency, to do targeted treatment. It is recommended that patients with hemorrhagic fever should seek medical treatment in time and under the guidance of a doctor to avoid delaying their condition.
