If the blood pressure is mildly to moderately elevated after surgery, it can be temporarily observed. If the blood pressure is significantly elevated, antihypertensive drugs such as nitroglycerin can be given to control the blood pressure in a safe range. Elevated blood pressure after surgery is often caused by postoperative pain and stress caused by surgery. If the patient has no history of organic cardiovascular disease and the blood pressure is only mildly to moderately elevated (systolic blood pressure of 140-159 mmHg or diastolic blood pressure of 90-99 mmHg), antihypertensive drugs can be temporarily dispensed with, and the blood pressure can be observed, while treatment such as analgesia and sleep improvement can be given proactively, to remove the triggers that caused the fluctuation of blood pressure. If the blood pressure is obviously elevated (systolic blood pressure ≥180 mm Hg or diastolic blood pressure ≥110 mm Hg), antihypertensive drugs, such as nitroglycerin, sodium nitroprusside, etc., can be given to control the blood pressure in the safe range. As the patient’s local surgical wound pain improves and the patient’s surgical stress is removed, blood pressure will gradually return to normal. It is recommended to follow the medical advice for treatment.
