Low blood pressure does not necessarily require blood transfusion. Blood transfusion is not required when blood pressure is lowered due to antihypertensive drugs, heart failure, or postural hypotension. Blood transfusion is needed when low blood pressure is caused by acute blood loss due to trauma or gastrointestinal bleeding.
Generally, when the blood pressure is lower than 90/60mmHg, it is called hypotension, and then the cause of the lower blood pressure should be identified and the primary disease should be treated. If the hypotension is caused by taking inappropriate antihypertensive drugs, heart failure, or postural hypotension, the antihypertensive drugs can be stopped in time, heart failure can be corrected, and if necessary, the blood pressure can be stabilized by transfusion of balancing fluid or bactrim, etc. Blood transfusion is not necessary.
When acute hemorrhagic shock is caused by traumatic bleeding or massive gastrointestinal bleeding, etc., blood transfusion treatment is needed in time to replenish blood volume and at the same time, anemia can be corrected and perfusion volume can be maintained, so as to buy time for further treatment.
When low blood pressure occurs, please go to the hospital for examination and treatment in time, and take reasonable treatment methods to avoid delaying the condition.
