Li Xiaofeng told Doctor Chen, "She is Teacher Shim’s junior, a surgical student, surnamed Xie."

A surgical student proficient in interventional surgical techniques? Doctor Chen was astonished.

Shim Youhuan turned his face with a smile, his lips curved towards his little junior sister. The gleam in his eyes said: Little junior sister is impressive.

Xie Wanying’s gaze fell on Senior Brother Shim’s hand holding the intercom communication button, knowing that Senior Brother Shim was being considerate by leaving a path for Doctor Yang, deliberately keeping the intercom open for Doctor Yang to hear. Because of this, she dared to finish her reminder in one go.

Clinical teachers don’t like it when students help each other cheat during exams.

After scanning the little junior sister’s calm demeanor, convinced that she had guessed his intention, Shim Youhuan’s eyebrows raised slightly, and he said to her, "I suddenly realize you’re a bit cunning."

Being labeled cunning by Senior Brother Shim. Xie Wanying wanted to say that Senior Brother Shim was the most cunning, clearly thinking it was inappropriate to instruct directly and let her speak on his behalf.

"Anatomy’s excellent." This voice came from Shilei, who had stealthily followed along.

The other two turned their heads upon hearing the voice, finally realizing someone was standing there.

Shim Youhuan turned his head back with a hum. What this Stone said was probably suggesting that surgical students learned anatomy better than medical students, a notion that medical seniors wouldn’t readily accept.

In fact, in clinical practice, there are hardly any medical students who can learn anatomy and immediately apply it to clinical practice, those who can are often called geniuses by their predecessors. Trying to translate textbook knowledge into the ever-changing patients is indescribably difficult and is something only gradually accumulated by doctors through clinical practice. Probably thinking of this, an idea popped into Shim Youhuan’s head for a moment, like Jin Tianyu: poach Student Xie to the medical department.

After the thought flashed, Shim Youhuan didn’t dare.

At Guo Zhi Hospital, no one dared offend Zhang Huayao. Student Xie was personally monitored by Zhang Huayao. This Stone staying here all night was surely commissioned by Zhang Huayao to act as his eyes on Student Xie, otherwise, why not get off work?

In the operating room, after clear guidance, Doctor Yang suddenly realized, his surgical ideas opened up, and he was no longer flustered.

"Teacher, I need fluoroscopy," Doctor Yang applied.

"Alright," Doctor Chen permitted while continuing to think that the person who gave the guidance was incredibly skilled; they went straight to the crucial points. If it weren’t for Li Xiaofeng saying who it was, he would have truly thought it was some master-level figure guiding Doctor Yang.

According to Xie Wanying’s oral instructions, with the potential position of the femoral artery confirmed, Doctor Yang confidently inserted the needle, obtaining blood return. Following existing medical procedures, the guidewire was inserted. The femoral artery has many branches, to avoid the guidewire accidentally entering small vessels, it’s best to operate under fluoroscopy. The J-shaped guidewire needs to be advanced to the aortic arch, similar to the previously mentioned transradial coronary angiography procedure, after vascular dilation, a sheath is placed along the guidewire.

Reaching this step, Doctor Yang, with zero hands-on experience with IABP, withdrew first, allowing the experienced Doctor Chen to take over. Doctor Chen needed to pass the balloon catheter’s central lumen over the guidewire, with the tip advanced along the sheath to a certain distance past the opening of the left subclavian artery in the descending aorta, approximately 1 to 2 centimeters. This position was between the second and third ribs.

With the balloon catheter in place, the next step was connecting the catheter to the counterpulsation machine.
