Controlled hypotension is a method and means of anesthesia. Its purpose is to reduce the patient's blood pressure, thereby minimizing a range of symptoms caused by pressure fluctuations, such as bleeding and arterial fluctuations.
Generally, controlled hypotension is commonly used in brain arterial aneurysm, heart surgery, and arterial aneurysm surgery in various parts of the body. Its most effective and commonly used benefit is that it can reduce bleeding by controlling blood pressure, providing a good surgical field for the operator, and reduce the pressure inside the arterial aneurysm, which prevents the aneurysm from rupturing during surgery!
This technique is usually operated by an anesthesiologist.
In the operating room, there is a saying that describes the relationship and difference between an anesthesiologist and a surgeon, "The anesthesiologist saves lives, the surgeon cures diseases."
