2614.2515 Bloodless Surgical Procedure

"That's meaningless." Su Yun said, "Humans have 46 chromosomes, gorillas have 48, so there's no way to be born with 47 chromosomes… huh? Why are we talking about this?"

"It's not your fault." Zheng Ren used sterile Gloves to tweak the patient's sole hair twice, pondering how to solve this problem.

"It has nothing to do with reproductive isolation or genetic alteration; I think the situation is like hair migration." Zheng Ren picked up the hair growing on the patient's sole with his fingers, lightly placed it on his fingertip, "It is embedded in the outermost layer of the skin, and as walking continually pushes it deeper, it gradually stimulates the nerve endings of the thicker layer of skin on the foot."

"Zheng Lao Ban, please speak slower." Zhou Litao didn't hear clearly; he asked if he didn't understand, and immediately spoke.

"How can I not understand anything you say?" Su Yun seemed to have forgotten the patient's sweaty foot smell, leaned over to Zheng Ren's finger, stared intently at that extremely fine hair, and said: "Indeed, I remember that article, the doctors in Xiba published."

"Yun Ge'er, what is it?" Zhou Litao asked.

"The Journal of Emergency Medicine Visual Magazine has similar case reports; I think Caucasians have softer hair, making hair migration unlikely." Su Yun said, "Normally, in Asian populations with coarser, harder hair, it is more likely to occur."

"But this hair… is a bit soft, right?"

Su Yun leaned in even closer, seriously examining the hair twisted between Zheng Ren's fingers.

Zheng Ren was worried that Su Yun would faint from the smell like Lin Yuan did; after looking for a while, his eyes were already brimming with tears.

It's not deep affection; it's just that the sour stench is too strong.

"Zheng Lao Ban, is this it?" Zhou Litao doubted, looking at the hair on the sole; it's really hard to link the patient's severe pain with it.

Zheng Ren then lightly touched the root of the hair with his other hand.

"Ah..." The patient immediately cried out in pain.

"Is it really that painful?" Su Yun asked.

"It hurts… not that much, but I've gotten used to it." The patient said somewhat fearfully: "Any little pressure, and it hurts when touched; I… I'm not faking it."

"I know, the hair penetrates the stratum corneum, extends deep into the sole, and touches the nerve endings." Zheng Ren said softly: "Looking at his pain condition, consider that the hair may have gone even deeper."

"With tweezers, I'll do it." Su Yun said.

"No." Zheng Ren said, "Take it out under the Microscope."

"Is this making a mountain out of a molehill?" Su Yun asked puzzledly.

"I've also read that article in the Journal of Emergency Medicine Visual Magazine; since the patient is Caucasian, his hair is softer, so tweezers can pull it out." He thinks this case needs caution; if any part of the hair remains deep, extracting it would be troublesome. Even if cut open, it couldn't be found.

Zheng Ren seriously spoke his true thoughts.

The patient sat on the examination bed, dazed, still trying to process what was just said about human-gorilla reproductive isolation, unable to recover.

What does this have to do with that? My heel hurts, and you've gone off on a tangent.

"Alright, put on your shoes and follow me to the treatment room." Zheng Ren said.

"Doctor, what are we going to do?" The patient blinked, then asked softly.

"The hair fell out, you stepped on it with your sole, then it penetrated the stratum corneum and reached the nerve endings." Zheng Ren said, "We need to pull out that hair for your condition to improve."

The patient still didn't understand; he felt this young doctor was somewhat young, but had a strong aura that didn't allow him to question.

He put on his shoes, tiptoed, and limped along to the treatment room.

"Lin Yuan, go to the Operating Room and fetch my Microscope." Zheng Ren said: "And also… never mind, you contact Yi Ren, I still need… or I'll just do it myself."

Zheng Ren probably thought giving a brief instruction was too troublesome, so he said a couple more things to the patient and turned to leave.

Lin Yuan looked surprised as Zheng Ren left, went to find the surgical equipment, and whispered: "Yun Ge'er, what is Zheng Lao Ban going to do?"

"Making a mountain out of a molehill." Su Yun said, "Just pull it out with tweezers; he insists on cutting the stratum corneum under the Microscope. Think about how thick hair is."

"60-90 micrometers." Lin Yuan said without thinking.

"Exactly, less than 1/10 millimeter. Your Zheng Lao Ban is mighty, going to perform a bloodless surgical procedure." Su Yun always speaks poorly, his mocking tone thick and impossible to dispel.

"Yun Ge'er, bloodless?"

"Cut the stratum corneum; the sole's stratum corneum is slightly thicker, about 100 micrometers. Then reach the germinative layer, where the adhesion between tissue and hair is not severe, and then pull out the hair."

"……"

Lin Yuan glanced at the patient, merely someone who came to the Emergency Department for consultation; no wonder Yun Ge'er said Zheng Lao Ban was making a mountain out of a molehill.

The patient silently sat on the treatment room bed waiting; soon he saw that young doctor carrying back a metal-filled surgical box.

When he put on the Microscope for surgery, opened the surgical box, and took out the small microsurgical instruments, the patient stared at Zheng Ren, full of technological feeling, with countless questions he wanted to ask.

Before he could ask, Zheng Ren said, "This is the black line in the skin, which needs to be differentiated from parasitic migration."

"If it were epidermal parasites, there wouldn't be fixed pain, and the itching would be intense. Now that we have experience, next time we encounter a similar situation, you'll know what to do."

As he spoke, the patient saw Zheng Ren install a tiny blade onto the handle, small like a child's toy. Yet the cold glints reflected from the blade made him feel somewhat apprehensive.

Although somewhat afraid, he gave himself psychological comfort in his mind.

"It's fine, it's fine, anesthesia will be needed anyway. I just don't know how fine a needle would be needed to administer anesthesia with such a tiny surgical blade."

"Wrong! Where's the needle for anesthesia? And also! No anesthetic drug!"

The patient stared blankly, not yet understanding what had happened, when Zheng Ren had already set the knife aside and picked up a pair of tweezers.

"Doctor, no anesthesia?" The patient asked anxiously.

"It's done, no anesthesia needed." Zheng Ren said lightly, then looked at the freshly removed hair under the light.

"This is……"

"It's because you walked barefoot at home and stepped on a hair. This hair drilled into your sole like a needle." Zheng Ren smiled, twisted the hair onto a piece of sterile gauze, then handed the sterile gauze to the patient.
