The causes of hypotension and treatment methods, according to the different causes to choose different treatment methods. 1, cardiac disease, when suffering from cardiac insufficiency, myocardial infarction, aortic stenosis, will cause the heart to beat the volume of weakened, resulting in a reduction in the amount of blood transfusion, thus causing the occurrence of hypotension, this time we should target cardiac insufficiency, myocardial infarction and aortic stenosis for targeted treatment. 2, peripheral circulation dilatation, because the bacteria or toxins invade the peripheral blood vessels, so that the loss of vasoconstriction, resulting in vasodilation, blood pressure drop, we must anti-bacterial, anti-toxic drugs to resist progressive blood pressure. The blood pressure should be reduced by antibacterial and antitoxin treatment, and some antihypertensive drugs should be used to resist the progressive decrease of blood pressure. 3. Temporary blood loss, a large amount of bleeding from trauma makes the blood volume of the body circulation suddenly decrease, causing temporary hypotension, and this time we should carry out 4, hypothyroidism, when the thyroid gland function is weakened, there will be loss of energy, physical and mental fatigue, lower blood pressure and so on, this time need to actively control thyroid function, the best to take thyroxine to improve the thyroid function of the situation, so as to raise blood pressure. 5, Addison’s disease, this disease can lead to paranephric cortical hormone secretion, appearing skin This disease can cause the secretion of paranephrine hormone, skin darkening, nausea, vomiting, hypotension, this time to actively control paranephrine, in order to control hypotension. 6, malnutrition, increased menstruation in women, this condition can also lead to hypotension, we must actively control anemia, supplement the hematopoietic material to correct anemia, correct hypotension.
