Director Shen must know Zhou Can's ability.

"The treatment of this patient is a bit special. It requires bone cavity apnea, which is extremely difficult. Not to mention you, even I need to be careful to succeed in the puncture. You can just watch and learn the operation steps carefully."

The patient was sent in quickly.

This is an old lady with white hair, her left knee is as swollen as her thigh.

It looks scary.

When I pushed in, I kept calling out.

This joint pain is very tormenting.

It is not the kind that can immediately hurt people to death. It is like cutting flesh with a dull knife, slowly tortureing people until their will collapse.

"Grandma, we will give you treatment right away. Please sit down and keep this position still."

When puncture of the knee joint cavity, it is best to sit in a sitting position when treating the patient.

This facilitates the selection of puncture points.

"Here, you all come and take a look. The puncture point is in this position."

Doctor Dan took a pen and drew the puncture point.

"This puncture point is not the only puncture point. You can take the inner or outer side of the patella as the puncture point according to the actual situation of the patient. If it is puncture from the outside, it should be this position."

She taught very carefully.

Ichisuke, who looked twenty-eight or nine years old, should be a resident. It seems that he has mastered the work of puncture of the knee joint cavity for a long time. He just watched from a distance.

Didn't get closer.

"After finding the puncture point, first use a 5mL syringe to pierce the joint cavity from this part. Until you have a sense of breakthrough, it means... uh, you need a sense of breakthrough to indicate that the puncture has been successful."

Her expression froze, and the puncture of the syringe on her hand seemed to have encountered obstacles.

"Oh...girl, please be gentle..."

The patient screamed in pain.

Dr. Shan couldn't help but blush.

When is Kuangpiao bad? He has to choose when she teaches students.

Didn’t this intentionally embarrass her?

The resident seemed to see Dr. Shan’s dilemma and hurried forward to help.

"Doctor Shan, we men are a little stronger, let me try it!"

He said this, obviously taking care of Dr. Shan’s face.

Help her to help.

"Puncture of the knee joint cavity is not easy to succeed. It is a secondary surgery. Be careful and do not do it recklessly."

She was very grateful for the male doctor's rescue.

I also took the opportunity to retreat aside.

The male doctor took the syringe, changed the needle and pierced it again.

"Um……"

The veins on the male doctor's hands were all revealed, and his strength must be quite strong. The old lady screamed in pain, and even her tone changed.

"It hurts, it hurts..."

She slapped the armrests of the wheelchair repeatedly.

It might have really hurt her.

If it doesn't hit the periosteum, it will definitely hurt to the bone marrow. No one can tolerate it.

"Doctor Tang, you take a rest first, I'll do it!"

Dr. Shan dared not let his subordinates do the operation anymore.

She watched the patient's film again and said a little embarrassedly, "Maybe the patient's joint lesions are more serious, and the difficulty of puncture is also increased. But it doesn't matter, it's the same, we switch to the outside of the lower part of the patella for puncture."

She changed into a new needle, comforting the patient, and finding the puncture point on the outside and then performing the puncture.

“Um…”

Judging from her expression, she must be scolding in her heart. How come she got stuck again?

Zhou Can kept standing by and watching.

He also watched the films made by the patient.

Just B-ultrasound, there is no way to clearly display the knee bones.

As Dr. Shan said, the patient's joints may undergo severe lesions, so the normal puncture point during puncture will not work.

After Doctor Shan tried twice, his face turned red and sweat was flowing out.

When teaching, one mistake was enough to embarrass her.

Who would have thought that the transition to the lateral puncture would not succeed?

This is just a preliminary puncture.

It's really embarrassing.

"Doctor Shan, I happened to have practiced puncture, why don't I try it!"

Zhou Can's injection is as high as level 4, and the attending physician is of moderate level.

When I got the injection before, I thought this medical technique might be of little use.

Now I understand.

Its use is not only for injections, but also for puncture.

Lumbar piercing, chest piercing, spinal piercing... all kinds of piercing activities should be controlled by the operating room standard trainees.

When studying in school, teachers often deceive students and learn how to physicalize them. They are not afraid of traveling around the world.

Now, Zhou Can wants to tell all doctors that if you practice ejaculation through injection, you can only have one injection of various punctures.

Doctors who need two, three, or even more times to succeed during puncture have failed to practice the injection.

Dr. Shan didn't know how to step down at this moment.

If you have failed many times, you may succeed by biting the bullet and puncture again. More likely, you will still fail.

Then the face will look even worse.

She was considering whether to ask someone to come and help.

Zhou Can volunteered. Although she didn't have any hope, it was always a good thing if someone helped her.

Otherwise, the first patient in the surgery would make her face come true. How could she teach these regular trainees later?

They dared not laugh at her in front of her.

There is still some criticism behind it.

"You should be careful, and I must stop immediately if I stop."

She reminded her a little worriedly.

"OK!"

Zhou Can took the syringe and replaced it with a new needle.

It must be said here that after the needle puncture is not successful, it is best to change to a new one.

The main purpose is to avoid bringing bacteria into it, which leads to infection in the originally sterile joint cavity. If the puncture causes infection, the consequences will be serious.

A needle doesn't cost much.

Anyway, it's included in the consumables.

Zhou Can touched the patient's joints and then stabbed it in with an injection.

"laugh!"

After the needle of the syringe was pierced into the cortex, it encountered obstacles and then pierced quickly.

The puncture was successful with one needle.

"Is this a puncture successful?"

Several regular trainees, including nurses and resident doctors, were all quiet.

Holding your breath.

Wait for the results.

Dr. Shan's little eyes instantly widened. It was not until she saw clearly that the needle was deeply immersed in the skin that Zhou Can was sure that the needle was in place and easily completed the puncture of the knee joint cavity.

"What awesome!"
