Chapter 1567 [1667] Technical Compensation

The technical principle of IABP is embodied here. It uses pure physical action to let the balloon input helium expand during the diastole of the patient's heart, blocking 90 to 95% of the arterial lumen, so that the blood pressure can be kept in the main body. Arterial root, increase diastolic blood pressure and coronary perfusion flow, increase myocardial blood supply and increase cardiac activity. Before the heart contracts, the air bag is deflated, the aortic pressure drops, the afterload of the heart decreases, the resistance of the heart to eject blood decreases, and the myocardial oxygen consumption decreases.

With so many effects that can be achieved together, IABP technology has incomparable unique advantages over other treatment methods.

Medical treatment requires a combination of several drugs, which has many side effects, and the effect is not necessarily good. Surgical LV assist devices have stricter anticoagulation requirements and higher risks than IABP. Due to the advantages of IABP, after the advent of IABP technology, clinicians are now the first choice for IABP for patients who can fit within the IABP indications.

All kinds of new technologies are good, but any medical operation has its technical difficulties, and IABP is no exception. Based on the above-mentioned principle of IABP, the balloon should have the best physical effect in human blood vessels. Like balloon hemostasis, the volume of the balloon after expansion needs to reach the target set by the doctor for the patient, otherwise the effect will be greatly reduced. .

It becomes critical to select the appropriate size of the balloon catheter for the patient's arterial vessel. There are adults only for adults, and children only for children. There is a slight deviation in the value of blood vessel diameter between women and men, and factors such as the patient's body, fatness, thinness, and blood lipid levels also show different blood vessel diameters.

In conclusion, the models of medical devices used by adults cannot be distinguished by too small thickness differences. What's more, the difference in thickness between the four conventional IABP catheters is small, but the difference in length is large, which shows that the doctor should choose the model according to the height of the patient. This is because in addition to the thickness of the balloon catheter, the balloon catheter is placed near the opening of the left subclavian artery at the top of the human blood vessel, and the tail end is to the renal artery under the diaphragm. It takes such a large volume of balloon to affect the blood flow of the human aorta.

It can only be said that when many small gaps affect the treatment effect, it can only be made up by the doctor's experience and operation techniques.

After the machine is connected, the surgeon observes the patient's blood pressure, heart rate, etc. on the machine. Based on these values, Dr. Chen makes fine adjustments. After several debugging, I always feel that I am not satisfied.

The time passed by every minute and every second, and the night was so dark that I could not see my fingers.

It's ten o'clock at night.

After a day's work, there is no difference between the leader and the subordinates, and his face is tired.

Sitting on the sofa chair in the dean's office, Zhang Huayao yawned. On the coffee table in front of him, the dean's secretary brought him a cup of coffee to relieve his troubles.

"I don't drink anymore." Zhang Huayao said, Dean Liang fed too much dinner tonight, and the coffee was a little too full.

Hearing what he said, the little secretary went to bring him a new cup of Longjing tea.

Didn't have time to drink tea, Zhang Huayao turned over the medical records page by page.

was guessed by Shin Yoo-hwan, who was caught by Dean Liang to help conduct cross-ocean consultations for his compatriots and study the patient's medical records.

Who's medical record? If the dean can personally invite experts from the hospital to come to the office to see the medical records, it must be the medical records of the rich and noble.

Thank you for your support! ! ! Good night dears~
