Correcting and improving the patient’s pathological and physiological status before anesthesia is usually very important. For patients with hypertension, if there is a history of intractable perennial hypertension, it should be controlled by systematic internal medicine treatment or preoperative consultation, the systolic blood pressure must be lower than 180 mmHg and diastolic blood pressure should be lower than 100 mmHg, which is the upper limit of it, within which the patient’s surgery will be somewhat safe, but controlled in the normotensive range as much as possible. In the choice of antihypertensive drugs is very important, because surgery will use central anesthetic drugs, antihypertensive drugs are likely to produce synergistic effects with anesthetic drugs, such as central antihypertensive drug lisdexamfetamine in the preoperative period can not be applied, at least to stop to more than 1 month, because of central antihypertensive drug lisdexamfetamine and anesthesia drugs, at the same time in the body after the reaction, it will occupy the receptor of the body’s vasoconstriction, so as to make the elevation of blood pressure The continuous action of the drug will lead to malignant hypotension and bradycardia during anesthesia, and patients often die due to hypotension. Therefore, in addition to blood pressure, the patient’s basal state should be observed preoperatively for anemia, hypovolemia, or multi-system problems in the cardiovascular system, respiratory, digestive, urinary, and neurological systems, and the various risks must be adequately assessed so that reversible factors can be corrected in a timely manner.
