With the improvement of people's living standards and changes in lifestyles, more and more people suffer from hypertension .
Hypertension refers to the pressure on the blood vessel wall when the blood flows in the blood vessel is higher than the normal value. It is one of the most common cardiovascular diseases and is also an important risk factor for diseases such as stroke , coronary heart disease , heart failure , and heart failure .
So, what are the criteria for hypertension?
If the antihypertensive drug is not used, the blood pressure value of the three non-same day measurements is higher than normal, that is, systolic blood pressure ≥140mmHg, and (or) diastolic blood pressure ≥90mmHg, which can diagnose hypertension.
You can see that this standard is different from the previous years. Previously, systolic blood pressure exceeding 120 was defined as hypertension. The standard of
has been improved, and many people have relaxed at once: they have finally been removed from the hypertensive population. Then, continue with the previous lifestyle. The changes in the standard of
Hypertension actually make the doctors very worried. What doctors are worried about is that people reduce their health requirements.
, I’m afraid, a restaurant owner recently called to inquire: Blood pressure 200 and blood pressure 160, which one has a higher risk of surgery?
asked clearly the reason and found out that he was going to have a gallbladder surgery recently. However, after hearing the doctor and the patient in the ward explain the risks, he began to worry. Because, he is also a hypertensive patient. However, the patient's blood pressure is 200 and his blood pressure is 160.
The risk was doctor in the department of anesthesia, and he also postponed the patient's surgery backwards, saying, "Wait until the blood pressure is better before the surgery." Hearing this, he began to worry that the doctor would not perform surgery on him.
Faced with his concerns like this, we clearly told him: the difference in the value of hypertension does not mean the magnitude of the risk. For example, if the blood pressure value is high, the risk is not necessarily high.
, he asked with a look of surprise: What is the reason?
During surgical anesthesia, the main risks of hypertension are cardiovascular and cerebrovascular accidents and insufficiency of blood supply to various organs.
Why does hypertension still cause blood supply incomplete blood?
This is the deviation of most people’s understanding: most people think that if the blood pressure is high, the blood volume in the blood vessel should be very large. Even some hypertensive patients will deliberately drink less water and porridge to reduce excessive water intake.
This approach is completely wrong: patients with hypertension must not deliberately restrict drinking water. Limiting drinking water may lead to blood concentration and high blood viscosity.
In addition, due to the long-term damage of hypertension, the spasm and sclerosis of small and medium arteries and the lumen becomes smaller.
If the blood pressure is lower, the blood flow rate in the blood vessels will be slower.
During surgical anesthesia, stress response, blood loss and the inhibition of anesthetics may all lead to a decrease in blood pressure.
Assuming that the above factors appear at the same time, organ ischemia is likely to occur. Therefore, ischemia is more likely to occur when hypertension occurs. Will
have bleeding risks?
will. For example, when the patient recovers from anesthesia, the blood vessel of the hypertensive patient has poor elasticity and weak buffering. In order to counter hypotension , the capacity input in the body may be the cause of bleeding risk. Sudden increase in blood pressure may cause hemorrhagic stroke in the patient during this period.
looked back and saw which one is more risky, , blood pressure 200 or blood pressure 160?
is not determined simply from the numerical value, but it can be numerical to judge that patients with blood pressure of 200 may not listen to advice or have serious hypertension.
Therefore, its risk may be greater. But it should be emphasized that this is not absolute, it mainly depends on the degree of damage caused to the body by hypertension.
In clinical practice, anesthesiologists often use blood pressure 180 as the standard for stopping surgery. The basis is that when blood pressure above 180 occurs, there is a high probability that the target organ damage may be serious.
pauses the operation, on the one hand, adjusts the blood pressure well, and on the other hand, it also makes the patient or family members pay attention to hypertension.After all, being able to let your blood pressure be so high means that there is a problem with your attitude.
Finally, let’s emphasize that medical guidelines are all very valuable and even painful lessons in the past, so we must obey the arrangements of medical staff. You can question it, but please keep it in your heart!
