All surgeries carry the potential for certain risks, even when everything is done properly. One of the most common risks is high blood pressure complications after surgery. To learn more about this situation, please follow the article below.

Patients may face high blood pressure after surgery for a number of reasons. Whether you develop additional complications after surgery depends on the type of surgery you have, the type of anesthetic you have, and whether you have had high blood pressure before.
Postoperative hypertension was defined as systolic blood pressure greater than 190 mmHg or diastolic blood pressure greater than 100 mmHg, or both, occurring after surgery. This phenomenon prompts immediate consideration of treatment.
Blood pressure is defined as the force of blood needed to exert on the walls of arteries to bring blood to the tissues of the body. A blood pressure reading consists of two numbers: the maximum blood pressure, also known as the systolic pressure, and the diastolic blood pressure, also known as the diastolic blood pressure. For adults, a blood pressure reading of about 120/80 mmHg is considered normal blood pressure.
According to the American Heart Association (AHA), blood pressure measurements are classified into 3 subgroups as follows:
Ideal range: <120mmHg for systolic blood pressure and <80mmHg for diastolic blood pressure; Prehypertension: Systolic blood pressure about 120 - 129 mmHg and diastolic blood pressure <80 mmHg; Hypertension: Systolic blood pressure >130 mmHg or diastolic blood pressure >80 mmHg. Heart surgery and surgery involving the aorta are often associated with a higher risk of high blood pressure after surgery, especially for people with a pre-existing history of high blood pressure. If you do not control your blood pressure well before entering the operating room, you will definitely face complications after surgery, which is hypertension.

Factors that are considered risk factors for developing hypertension after surgery include: high body mass index (BMI), age, and stress level of surgery. Significant postoperative hypertension can cause serious complications such as heart failure, arrhythmias, myocardial ischemia, incisional bleeding, and cerebral hemorrhage.

High blood pressure after surgery can be caused by the following:

If your body is used to medications that lower blood pressure, stopping them suddenly can cause your blood pressure to rise again immediately.
Therefore, you need to tell your surgeon about this before doing surgery. Be detailed about the classes of medications you take and any missed doses. Some blood pressure medications can be taken the morning of surgery, so you don't have to worry about missing a dose. You should confirm this with your surgeon or anesthesiologist.

Pain can cause your blood pressure to rise higher than normal. However, rest assured that this problem does not last long. Blood pressure will return to normal after taking pain medication.

Anesthesia can have a negative impact on your blood pressure. Experts note that some people's respiratory systems are quite sensitive to breathing tubes. This can stimulate a faster heart rate and cause a temporary increase in blood pressure.
Recovery from anesthesia also has the potential to cause high blood pressure after surgery. Factors such as body temperature and the amount of intravenous fluid needed during anesthesia and surgery can lead to hypertension.

When under anesthesia, your body is likely not getting the oxygen it needs. This leads to a decrease in the amount of oxygen in the blood, causing hypoxemia. As a result, blood pressure increases.

Certain prescription or over-the-counter medications can raise your blood pressure. People with high blood pressure who take non-steroidal anti-inflammatory drugs (NSAIDs) may experience side effects, making the condition worse. If you have high blood pressure, ask your doctor about options for pain control before performing surgery. They may recommend different treatments or prescribe alternative medications.
If you have no history of hypertension, any symptoms of high blood pressure after surgery may be temporary. It usually lasts about 48 hours. The doctors and nurses will monitor your health and use medication to lower your blood pressure back to the ideal range. If you have a history of high blood pressure, proper control of your blood pressure will limit your risk of developing it. In addition, discuss the plan in detail with your doctor before surgery to reduce the risk of risks.

In order to assess your blood pressure status and control your blood pressure well, you should go to a reputable hospital to be prescribed by a doctor to carry out the necessary diagnostic measures. The basic hypertension package and the advanced hypertension package deployed by Vinmec International General Hospital are the first choice to help you accurately determine your blood pressure status and receive practical advice from your doctor. doctor to protect your heart health.
