Capítulo 1397: 【1397】Specificity
If he wants to collaborate with her, they will need to climb the same incredibly challenging mountain path in the future. The process will undoubtedly be arduous, but overcoming all obstacles might lead them to reach the Mount Everest of medicine.
Pan Shihua’s gentle eyes changed, and his fair face was tinged with a stern expression.
Soon, Jin Tianyu discovered that Student Pan, who appeared gentle and frail, seemed unremarkable; it turns out this person was capable and not overwhelmed by his gaze.
In the control room, a group of seniors keenly scanned the two students in the operating room, observing their every move.
After completing the preparatory work, Xie Wanying, with her gloved right hand, picked up the super-slippery guidewire that Doctor Fang hadn’t been able to deliver to the heart target.
As the name suggests, the super-slippery guidewire is extremely slippery, made from a special hydrophilic material, and becomes quite slippery with a bit of water, making it easy to navigate through blood vessels. For patients with stenosed and diseased blood vessels, such a tool increases the chances of threading the guidewire through narrow sections, thus enhancing the success rate of balloon dilation and stent placement.
However, some doctors are not very fond of using such super-slippery materials, preferring the principle of using standard guidewires with non-hydrophilic materials first. If the guidewire cannot pass through the diseased area, then the hydrophilic material can be chosen. The reason is simple: if it’s too slippery, it might mistakenly enter small vascular branches. For beginners, especially, it’s challenging to control this degree. Entering small vessels by mistake can cause significant accidents, and if the guidewire tears a blood vessel inside the body, creating a dissection and bleeding, it doesn’t matter if it’s a small or large vessel. The super-slippery guidewire will equally tear through a small vessel because no matter how slippery it’s made, the diameter remains the same and can rupture small-diameter vessels.
Doctor Fang’s choice of a super-slippery guidewire was out of necessity, given that they anticipated the patient’s coronary artery stenosis to be severe. Switching back and forth with regular guidewire would be repetitive and cumbersome.
They could only continue to use the super-slippery guidewire.
Jin Tianyu and the others did not forget that it was probably Xie Wanying’s first time using it, and they watched intently to see if her hands could hold it steadily. Controlling a super-slippery guidewire is challenging. The doctor must hold it steadily, controlling its head to prevent erratic movement within the vascular system, with its path constantly under the doctor’s hand and mental control. Typically, this requires the doctor to have skilled experience. Without experience, one can rely on similar previous operations and acquired knowledge.
The group diligently observed that her hand placement was correct, which indicated that her claim of watching teaching videos was true and that she was not entirely unfamiliar with PCI.
Jin Tianyu, though confident, was also very cautious, advising her, “Go slowly; I know you seem confident, but don’t rush.”
She had considerable experience with such long-distance controlling instruments, including bronchoscopes, gastroscopes, and laparoscopes. Therefore, as long as the guidewire was at her fingertips, her sense of touch and brain quickly adapted. Hence, Senior Jin judged this about her, fearing that she would act swiftly as she usually did once she gauged it correctly.
The usually impatient Senior Jin at this moment was, well, more like the extremely composed Teacher Nie.
Technical experts have this in common: when it comes to being careful, they appear more cautious and timid than the average doctor.
The senior’s advice had to be heeded. Xie Wanying followed the senior’s guidance, nodding, holding the guidewire steadily, her eyes fixed on the puncture site and the patient’s entire left upper limb, once again mentally verifying her hypothesized route map.
