A simple femoral vein puncture Yuntian has been practiced hundreds of times.

Practice until you can accurately insert into the femoral vein at one time and hit the nail on the head before you start the next step.

Into the vascular sheath, insert the guidewire, look at the projection screen on the device, the microwire begins to swim in the blood vessels.

Although it was just a simple action, Yuntian was very laborious.

Although I got the intermediate skill of CTPA from the system, the body's response and cāo) made it completely unable to keep up. Therefore, Yuntian controls the micro-guidewire and does not walk smoothly.

However, after all, it is an intermediate skill book, and although Yuntian is not very smooth, he still keeps moving forward, fortunately, there are no accidents.

Traveling all the way up from the femoral vein, when the catheter reached the pulmonary artery, Yuntian felt that he was all soaked in sweat!

Connect the pressurized injector and inject the contrast medium!

This cāo) requires a scan to be completed at the pulmonary arterial stage.

This results in images that are not interfered with by the pulmonary veins.

But after all, Yuntian is the first time to make it, the speed is a little slower, and the timing is slightly lacking.

In addition to arterial shadows, there are quite a few pulmonary vein artifacts!

The first imaging was a failure.

There are too many pulmonary vein artifacts, and the film is so dense that it is impossible to identify at all.

Yun Tian glanced at the system time, and an hour and a half had passed.

Taking a deep breath, a new simulated test subject appears.

The clouds began to re-cāo).

In 24 hours, the same arteriography was done nearly 20 times in Yuntian.

Until the system training time was cleared, Yuntian was kicked out of the system training room.

Wearing thirty or forty pounds of lead clothing, he repeatedly performed venipuncture, catheterization, and contrast injection for 24 hours in a row, and Yun Tian returned to the doctor's office still in a slight trance.

Fortunately, after Yun Tian exchanged the CTPA technique with the intermediate skill book, he had actually completely mastered the key points of this technique, and then practiced repeatedly for 24 hours, just to keep up with the body's reaction speed.

Therefore, at this time, from the simple operation of CTPA, Yuntian has completely mastered it.

Looking at the time, plus the five hours of learning and absorbing relevant knowledge points at the beginning, Yuntian has been in the system training room for more than 29 hours.

But in reality, time is still stuck in the moment when Yun Tian enters the doctor's duty room.

It's just that whether it is the soreness of the arm or the stinging pain of the finger twisting the micro-guidewire, it reminds Yuntian that he has indeed mastered the invasive examination method of CTPA.

But again, it is impossible to complete this procedure in the current state.

After thinking about it, Yuntian spent 100 experience points and exchanged it with the system for a bottle of energy-restoring potion and drank it.

After drinking the energy potion, the mental power was significantly restored.

The soreness in the arm and the tingling in the fingers all disappeared together.

Even the anxiety caused by worrying about Uncle Zhao's illness disappeared together.

The energy potion produced by the system is really powerful.

When I returned to the ward again, Uncle Zhao's condition

Slightly better.

But the heart rate is still around 140 beats per minute.

Although the heart rate has decreased, the situation is still not optimistic.

The diagnosis must now be made as soon as possible.

The best way to make a definitive diagnosis is CTPA.

Yun Tian picked up the phone and dialed Director Shi again.

"Director Shi, I suspect that 38 patients have pulmonary embolism, and CTPA confirmatory examination should be performed as soon as possible. ”

On the other end of the phone, Director Shi was silent for a while.

"I'm already at the hospital, come and talk about it. Director Shi did not answer Yuntian's request clearly, but hung up the phone.

Zhao Lei lowered his head and stood quietly in the corner of the ward, silent.

Yun Tian walked over and patted Zhao Lei's arm for comfort, there were a thousand words to comfort his closest brother, but he opened his mouth and didn't say a word.

Not long after, Director Shi appeared at the door of the ward, accompanied by Director Tang Feiyi of the Department of Cardiology.

"The patient suddenly fainted 30 minutes ago, and his blood pressure ......" Yun Tian immediately stepped forward and reported Uncle Zhao's situation to Director Shi.

Director Shi quietly listened to Yun Tian's report on the patient's condition and glanced at Director Tang Feiyi.

Regardless of the top departments of Xihua Cardiology, the interventional catheterization laboratory has just been launched.

Now there is only one person who can do it, Tang Feiyi, the director of the department.

In recent years, as a new type of coronary heart disease treatment, cardiac stent surgery has been popular, and since the business of the interventional catheterization laboratory was opened, Director Tang has been in high-load operation.

Patients who have been waiting for stent surgery have appointments for several months.

Today alone, Director Tang has already performed eight stent surgeries. Eight stent surgeries a day is definitely the limit.

It's not just a matter of energy, interventional surgery needs to be carried out under X-rays, although there are thirty or forty pounds of lead clothing protection, but even lead clothing cannot completely isolate radiation damage.

Therefore, although he made a phone call, Director Tang agreed to come over and take a look at his face, but he knew in his heart that Director Tang definitely didn't have the energy to do a CTPA again.

No matter what, it is impossible for me to ask Director Tang to add a CTPA examination.

Touching Director Shi's gaze, Director Tang Feiyi was also a little helpless:

"I made eight brackets today, not to mention the wire problem, I am old, and lack of energy is the biggest problem. "Although Director Tang is only in his early forties, perhaps because he is too tired, he looks much older than Director Shi.

Yun Tian had already heard about the situation in the Xihua Cath Laboratory, which is why Yun Tian entered the system training room and spent a huge price to learn the CTPA procedure when he decided to do CTPA for Uncle Zhao.

"Director Shi, I can try. "Director Shi is not Director Lin, and he does not have the absolute trust that Director Lin has in himself.

Therefore, when Yun Tian said this, he was very quiet and had no confidence.

After all, an intern who has not been in contact with someone who has intervened in a different room says that he can do it

CTPA？

It sounds a bit mysterious.

Sure enough, after listening to Yun Tian's words, Director Shi glanced up at Yun Tian, his eyes full of consternation.

Not only Director Shi, but even Director Tang raised his head in surprise.

The cardiac catheter project in Xihua Hospital has been carried out for several months, and Director Tang and the doctors in the department have done it countless times.

But so far, there is not a single person in the department who can do it.

Therefore, how could Director Tang not be surprised to hear this intern who had not been exposed to interventional catheter-related disciplines say that he could do CTPA alone!

Although CTPA is not as complex as cardiac stents, and the requirements are not as high, it is a relatively easy procedure in the field of interventional catheterization, but it is not something that an intern can complete!
