Hello, I’m Doctor Jaehyun Park at Dana Plastic Surgery. Today I am going to talk about epinephrine, a vasoconstrictor. And the sub-topic is about how to reduce blood loss during surgery. For the people who had surgery in our hospital are watching this video They will understand what I am saying. After surgery, when they come for shampoo and other treatments

they ask me why is there no blood clot? On the internet I saw a lot of reviews on hair transplant and they all had blood clots. But why don’t I get any blood clots after surgery? This is because the amount of blood loss during surgery is minimal. I would like to talk about the secret behind epinephrine today. Think about the emergency room where a patient is coming in from a car accident

and the blood pressure is not stable. The emergency medical doctor will tell the nurses to give epinephrine. You might have seen this in a movie or somewhere before but Epinephrine increases blood pressure. In other words, if the blood pressure increases the blood vessels shrink. Epinephrine is a vasoconstrictor. But if it wasn’t used

Or has lost its effectiveness than there will be blood loss. For the surgery department to not use epinephrine is something I cannot imagine. Since it constricts the blood vessels it is used in every surgery. But there are exceptions such as the tip of the finger. If you use epinephrine for the tip of the finger the blood will not be able to go through And eventually rot. Or for instance the male genitals

Since the blood will not circulate around this area, it will rot. If it’s not the extremities, epinephrine is the fundamental for any kind of surgery. But by using epinephrine at different volume and area I realized that it was different for each part of the body. I started to do extensive research on this.

For the people who watch our videos frequently may already know but we only tell you medically proved information. We study the latest knowledge and share it on our video. Consistently doing extensive research and sharing information is the philosophy of our hospital. As you can see here, this is the thesis that we

presented on dermatologic surgery journal. It’s about how the different concentrations of epinephrine used affect the constriction of the vessels. As you can see, we use laser doppler equipment to measure the constriction. This is one expensive equipment. On this figure 3 graph, you will see that

Depending on the volume, the time it takes will be 1:400,000 to 1:50,000. As the number goes down the amount of epinephrine is greater. To put it simply, if it goes from 1:400,000 to 1:200,000 the concentration will be two times higher. If its 100,000 it will be 4 times and so forth. And if it goes from 100,000 to 50,000 it will be double the concentration.

And then we compared the A and B area. We determined that the time varies for different concentrations from A and B area. I have been explaining this in a difficult way but For instance, using the vasoconstrictor in the middle section of the hairline and the outer region will have different effects.

What will happen is that as you are implanting and move towards the other area The effect of epinephrine would be almost gone which will result in blood loss. Blood loss is not simply about forming a blood clot. If there is blood loss, the blood will push out the hair follicle. It also causes the survival rate to decrease because of blood clots in between skin tissue.

And if this happens, you will have to push in the hair follicle again Causing damage to the skin which will make the surgery result worse. How you use epinephrine is extremely important. It will decide whether you go through the surgery bloodless or soaked in blood. We have presented our thesis on epinephrine and how we used it for over 10 years

with the laser doppler. I think I have helped other doctors about this problem. Therefore, all the patients that have gone through surgery at our hospital Say that there is almost no blood less and are satisfied with their results.
