Chapter 1602 652: Prolonging the Endurance Limit with Hypothermia—A New Knife Technique Combining Strengths of Three Schools (Part 2)
Director Feng calmly sat at the rear, safeguarding the patient's life.
His gaze was extremely sharp, sometimes staring at the monitor's dials and screens, sometimes watching the progress of the patient's surgery.
Zhou Can dissected step by step, finally reaching the brainstem region.
Even after so many years, the surgical scars left after the tumor was excised could still be seen.
The average person couldn't tell, but Zhou Can, with his rich neurosurgical experience, could immediately identify the deficient areas.
"Teacher, was the nerve cut here back then?"
Zhou Can pointed beside the trigeminal nerve extending near the brainstem and asked.
"Yes, a cut was made here at the pons. At the time, the tumor was large and had infiltrated the brainstem region. If the surgery wasn't thorough, recurrence was certain. There were only two choices: either to risk everything and make a daring attempt, or to close the cranial cavity, sew it up, and tell the family that the difficulty was too great, surgery was impossible."
Dr. Xu did not continue.
He chose the former.
Taking a daring risk.
The result was his life being ruined thereafter, losing his bright future, and directly falling into an abyss.
Being a surgeon is genuinely difficult, striving to become a benevolent and skilled surgeon is even harder.
If Dr. Xu were to choose again, he might choose the latter.
Close the cranial cavity again and announce that surgery was impossible.
Such situations occur from time to time in hospitals, though it's somewhat embarrassing, it's certainly better than something going wrong.
"Was it closed again after being cut open?"
"Repair was done, but the results were unsatisfactory."
Dr. Xu frankly admitted.
"Looking at this situation, we must cut open the area repaired back then, debride it, then re-anastomose."
After careful examination, Zhou Can said this.
Nerve anastomosis is extremely difficult.
Moreover, nerve cells are the only non-renewable cells.
They can't automatically repair or heal like other bodily tissues.
During nerve anastomosis, there are tens of thousands of nerve guidewires inside, each one must be correctly placed to ensure the optimal effect of the nerve anastomosis.
If some guidewires misalign or miss, that's akin to what people often say when scolding, "misaligned nerves."
The consequences are imaginable.
"Director Feng, Director Liu, I'm about to operate on the brainstem. The patient's vital signs might disappear at that time. How long can you give me at most?"
Zhou Can took a deep breath, but his gaze remained firm.
"Within three minutes is the safest, the shorter the time the better."
Director Feng directly responded.
The brainstem is called the life forbidden zone; not to mention cutting it, even peripheral areas seldom have doctors daring to touch.
Currently, domestically only a few major hospitals dare to claim that the brainstem is no longer a life forbidden zone.
Tu Ya barely has some strength in this aspect.
But honestly, Wu Baihe never gambles with his future and tomorrow; as long as the risk is too high, he gives up.
Unless the family is willing to sign a waiver and Tu Ya's legal team steps in to sign documents.
If two of ten brainstem surgeries succeed, that's already quite good.
Zhou Can's Incision Skill is still a bit short of Level 7, while debridement, anastomosis, suturing, knotting, and pathological diagnosis are all Level 7. It's fair to say he's capable of making an attempt, but not fully confident.
His Stable Knife Technique and Fast Knife Skill have been stuck at the Second Realm, unable to break through to the third realm, which also caused his Incision Skill to be stuck at level six.
Debridement and incision are extremely closely linked.
Especially for Mr. Song's brainstem repair site; wanting to cut open, then debride, is unimaginably difficult.
"Three minutes definitely won't be enough, I have no confidence at all."
Zhou Can shook his head.
Cutting open, debriding, then quickly anastomosing—not to mention three minutes—even doing it all within thirty minutes would be top-tier in the field of neurosurgery.
"Then how much time do you need?"
Director Liu from the Intensive Care Medicine Department asked.
"Conservatively estimating, at least around ten minutes is needed."
If Zhou Can's Fast Knife Skill and Stable Knife Technique could break through, this time might be shortened quite a bit more.
Because the quality of the incision directly correlates with the debridement difficulty.
It also affects the difficulty and effect of suturing.
After Director Liu listened, he turned to look at Director Feng.
"Old Feng, should we maybe try the cooling method? Apart from that, I'm afraid there's no better way to extend the time to ten minutes."
"This method is quite good."
Director Feng's eyes brightened slightly, nodding in agreement.
Consumptions are two different concepts between low and normal temperature environments.
Nowadays, the technology for cryogenically preserving life is quite mature, and in sci-fi films, there are people frozen by an avalanche on snowy mountains. Then after years, using thawing technology, the person comes back to life.
The operating room temperature is usually controlled at around 25 degrees.
Because the patient is undergoing surgery naked, this temperature is most friendly to the patient.
In winter, the operating room temperature is generally adjusted to above 20 degrees, with twenty-two or three degrees being most suitable. In summer, it's appropriate to maintain the temperature below 26 degrees.
Human wisdom is infinite.
In conventional surgeries, the operating room temperature is controlled within this range, but for special surgeries, reducing the temperature can aid in the smooth execution of the procedure.
The most common practice is to lower the temperature to around 15 degrees.
At this time, the body's blood circulation, metabolic rate will correspondingly slow down, which is extremely beneficial for controlling bleeding, extending surgical duration.
"We can extend the time by about threefold by adjusting the room temperature, within 9 minutes should be relatively safe. Do you think you can handle it?"
