Hemorrhagic fever, also known as renal syndrome hemorrhagic fever (epidemic hemorrhagic fever), is an acute natural epidemic disease caused by hantavirus and transmitted mainly by rodents, with a rapid onset, severe symptoms, and strong contagiousness, it is a relatively serious infectious disease, which, if left untreated, can lead to infections and other complications, with a certain degree of fatal risk. Is hemorrhagic fever serious? Hemorrhagic fever is characterized by sudden high fever, chills, hypotensive shock in 1-3 days, accompanied by systemic coagulation abnormalities, resulting in systemic vascular hemorrhage, which can lead to secondary infections, acute renal failure, and other systemic complications, seriously endangering the safety of life, with a certain degree of fatal risk. How to treat hemorrhagic fever? Hemorrhagic fever should be actively treated with antiviral and antipyretic treatment in the early stage, while in the middle and late stage, active prevention of hemorrhage and shock and pro-diuretic treatment are needed to prevent complications.1. Antiviral treatment: it is recommended to actively apply antiviral drugs, such as intravenous ribavirin and intramuscular interferon, within 3-5 days after the onset of the disease to effectively control the replication of hantaviruses in the body.2. Antipyretic treatment: for patients with high fever, the We can use warm towel to wipe the whole body and other physical ways to reduce the temperature, if necessary, under the guidance of the doctor to take ibuprofen, acetaminophen and other drugs to reduce fever.3, prevention of hemorrhage treatment: intravenous infusion of triclosan, vitamin C, in order to reduce the permeability of blood vessels to prevent bleeding, as well as infusion of glucose saline, to reduce the vascular exudate, and if necessary, can be transfused with albumin, as well as plasma fractions; 4, prevention of shock treatment: mainly use of Dextrose anhydride, balanced salt solution, etc. to reduce blood viscosity, supplement blood volume, sodium bicarbonate solution, etc. to prevent or correct acidosis, if necessary, can be injected intravenously dopamine, dilate the microvessels, relieve vasospasm, so as to play a role in preventing shock; 5, diuresis: due to the reduction of systemic effective circulating blood flow, renal blood flow is insufficient, resulting in renal mesangial edema compression of the renal tubules, oliguria symptoms. Treatment is often intravenous furosemide, supplemental albumin, promote urination. Patients with acute renal failure can be treated with hemodialysis. In addition, patients with hemorrhagic fever need strict bed rest, and the diet should be nutritious and easy to digest. After discharge from the hospital, they should rest for 1-2 months, and regularly review the renal function, blood pressure and pituitary function, and if there is any abnormality, it should be treated in time.
