21st Century Necromancer-Chapter 661 - 657: During Surgery (Seeking Subscriptions, Seeking Monthly Tickets)

Meanwhile, a nurse handed him the artificial blood vessel that had already been prepared.

Trimming the artificial blood vessel to the appropriate length, placing it into the right atrial appendix, and suturing it, Chen Yu then looked towards Kohinata Kaori, who had also completed the cutting of the left Anonymous Vein by this time.

"Anastomose the artificial blood vessel with the distal end of the left Anonymous Vein," Chen Yu handed the other end of the artificial blood vessel to her, and at this point, the artificial blood vessel was already filled with blood.

Kohinata Kaori took the artificial blood vessel, and with some nervousness, connected it to the patient's left Anonymous Vein, completing the vascular bridging. This replaced the cut blood vessel and ensured the patient's blood circulation.

Seeing the artificial blood vessel bridging completed, Chen Yu slightly nodded in approval of his junior's performance. However, he also said to her, "Next, we need to remove the tumor; we have to move a bit faster now."

"Yes, Senior," Kohinata Kaori quickly responded.

The tumor inside the patient was extremely large; fully separating and removing a tumor body larger than 12 cm was a very complex and troublesome task.

Especially since the patient's Superior Vena Cava had already formed a tumor thrombus, and the tumor had invaded the lung lobes, it was necessary to excise the involved parts of the lung lobes as well as the Superior Vena Cava while removing the tumor.

With the assistance of Kohinata Kaori, Chen Yu finally succeeded in completely freeing the tumor, but he didn't proceed to remove it. Instead, he said to Kohinata Kaori, "Kaori, please remove the tumor, taking care not to damage the surrounding vessels and organs."

"I understand." Kohinata Kaori knew this was Chen Yu's way of training her. After drawing in a deep breath of air filled with the acrid and bloody smell, she reached into the patient's chest cavity and removed the tumor, which was larger than her palm.

Chen Yu was very pleased with Kohinata Kaori's performance but still reminded her, "Taking a deep breath before an action can indeed help stabilize your emotions, but the air in the operating room isn't so healthy to breathe, even though we are wearing masks. The surgical smoke generated by the electrocautery cutting into the wound contains over 600 components that are harmful to the human body, which can cause headaches, dizziness, nausea, vomiting, and upper respiratory tract irritation, among other reactions. Long-term exposure can even lead to cancer, teratogenesis, and reduced fertility, so don't take deep breaths in the operating room unless necessary."

"Yes, Senior Brother!" Kohinata Kaori was actually not very aware of the risks of surgical smoke; she only knew that during surgery, someone had to evacuate the smoke, usually the second or third assistant's job.

Yet, no matter how much smoke is evacuated, there are still odors and harmful substances that reach the doctors less than half a meter away from the operating table, so it's not surprising to smell acrid or various strange odors during surgery.

However, the dangers these odors bring... These were not mentioned in the textbooks studied in school.

At that moment, Jounouchi Hiromi, who was sitting aside, heard Chen Yu talking about the hazards of surgical smoke and interjected, "Don't underestimate the dangers of surgical smoke. Although it does not cause rapid onset illnesses, like smoking, long-term exposure can lead to various severe consequences. Moreover, the smoke produced by the electrocautery when ablating 1g of tissue is as harmful as that of 6 unfiltered cigarettes, and a significant amount of tissue is often ablated in surgery."

"Isn't there any way to prevent it?" Kohinata Kaori asked Chen Yu. In her mind, her Senior Brother always had many ingenious ideas, capable of solving many problems, as if there was nothing that could get the better of him.

"Prevent?" Chen Yu looked at Kohinata Kaori with profound meaning, shook his head, and continued the surgery while saying, "The protective level of surgical masks is tested with 0.3μm diameter particles as the reference. The protection efficiency of a 90-rated mask is 90%, and that of our commonly used N95 standard mask is 95%.

But most particles in surgical smoke have diameters ≤ 0.31μm, with some even less than 0.2μm. Even if you wear a highly filtrating surgical mask, eye protection goggles, gloves, and a gown, the typical surgical mask can only block airborne particles of 5μm or larger and does not provide adequate smoke filtration protection. Like now, while you're wearing your mask, can you smell any odors?"

After Chen Yu finished his question, Kohinata Kaori couldn't help but take another sniff, and she smelled a strong burnt odor.

Watching Kohinata Kaori, Chen Yu slightly shook his head and said to her, "That's alright, these issues can't be resolved overnight, nor will they harm you that quickly. Rather than worry about this, focus on finishing the surgery first."

"I understand, Senior Brother." Kohinata Kaori quickly adjusted her mood and refocused her attention on the surgery.

As the surgery continued, Jounouchi Hiromi suddenly spoke out, "Darling, let's have barbecue after the surgery is over. I'm craving barbecue."

"Sure, just not sure if the boss has barbecue," Chen Yu glanced at Kohinata Kaori while replying to his wife.
