When I'm on the night shift, all the department heads can't sleep.

The corridor outside the emergency intensive care unit was filled with the smell of highly concentrated disinfectant.

Fang Rui clutched a newly printed urgent biochemical test report tightly in his hand, staring at the numbers marked in red, his hands trembling as if he were shaking.

"Teacher Lin..." Fang Rui swallowed hard, his saliva extremely dry, and handed the form to Lin Ye, who had just come out from inside after the handover. "The results are in."

Lin Ye took the test results and glanced at them.

Creatine kinase (CK): 38500 U/L

Myoglobin (MYO): >4000 ng/mL

Serum potassium (K+): 6.2 mmol/L

Lin Ye's gaze did not waver much; this result was entirely within his expectations.

"See?" Lin Ye handed the lab report back to Fang Rui, his tone as calm as if stating an objective fact. "His muscles have already undergone extensive necrosis and dissolution due to extreme rigidity. A large amount of intracellular fluid is rushing into his bloodstream. His blood potassium level is now 6.2, teetering on the brink of cardiac arrest."

Fang Rui looked at the number 6.2 and felt a chill run down his spine; cold sweat soaked through his inner clothes once again.

"If you were to inject that depolarizing muscle relaxant in the corridor on the eighth floor..." Lin Ye looked at him, mercilessly pointing out the cruel "what if," "it would cause his already collapsing muscle cells to undergo one last violent depolarizing contraction. Within a second, a large number of potassium ions would cascade into his bloodstream. His blood potassium level would instantly spike above 8.0."

Lin Ye paused for a moment, his voice low: "His heart simply can't hold out until the elevator doors close."

Fang Rui gasped, his legs went weak, and his back slammed against the cold wall of the corridor.

He used to think that the dangers of the emergency room came from unpredictable car accidents, poisonings, and injuries.

Only today has he truly realized that the real abyss is often hidden within those seemingly "standard" rescue procedures.

"Teacher Lin, thank you." Fang Rui raised his head, the frivolity of a resident trainee gone, replaced by an almost religious reverence in his eyes. "If it weren't for your safety net, I would have killed a patient with my own hands today."

"No need to thank me, just remember this lesson. Go back and write down the contraindications for muscle relaxants used in rapid induction intubation fifty times." Lin Ye patted him on the shoulder. "Let's go, they've already started using a hemodialysis machine to clean out the toxins inside. His life is saved, the rest is up to our colleagues in intensive care."

3 PM, Emergency Department Director's Office.

Lin Ye had just finished processing a few observation medical records when a nurse called him in.

Pushing open the door, besides Qin Hai sitting behind his desk, there were two other people in white coats sitting on the sofa.

One of them was Dr. Wang, the psychiatrist I had seen on the eighth floor that morning; he was sitting somewhat awkwardly on the edge.

The other was a senior doctor in his fifties with some gray hair.

"Lin Ye, come here." Qin Hai pointed to the empty sofa next to him. "This is Director Zhao from the psychiatry department. He came down specifically to see you."

Lin Ye was slightly taken aback, then quickly went over to greet him: "Hello, Director Zhao."

Director Zhao stood up, and instead of putting on airs as the head of a higher-level college, he solemnly extended both hands and firmly grasped Lin Ye's hands.

"Dr. Lin, you're a force to be reckoned with!" Director Zhao's voice was tinged with lingering fear and deep gratitude. "I just finished the hospital's administrative meeting at noon and heard Xiao Wang report on the morning's events. If it weren't for your RRT team's quick action and sharp eyes, that young man would definitely be dead today."

Lin Ye was a little overwhelmed by the enthusiasm.

"Director Zhao, you're too kind. This is what we at RRT should do. Malignant syndrome is extremely rare, and its initial symptoms are too similar to severe encephalitis and sepsis. It's extremely easy to misdiagnose, let alone in the psychiatric ward, or even in the emergency room."

"Yes, everyone has their own expertise." Director Zhao sighed, letting go of his hand and sitting back on the sofa. "Our psychiatry department is a closed, isolated island. We are best at communicating with the mentally ill and know how to adjust the dosage of antipsychotic drugs. But once a patient's bodily systems completely collapse, those drugs that are routine to us become poison. We are blind when it comes to physical emergency care."

At this point, Director Zhao turned to look at Dr. Wang next to him, whose head was bowed even lower.

"Xiao Wang told me about how he almost gave the wrong muscle relaxant in the corridor." Director Zhao looked at Lin Ye with admiration in his eyes. "Using succinylcholine for emergency intubation is a routine procedure written in many old textbooks. In those fractions of a second, you were able to see through the fatal taboo between malignant syndrome and depolarizing muscle relaxants, and you managed to stop the intubation risk... This kind of composure in a desperate situation is unparalleled among the younger generation of the First Municipal Hospital."

Qin Hai sat behind his desk, picked up his thermos, took a sip of tea, and a proud smile appeared on his lips, but he didn't show it.

"Director Zhao, this is why the hospital is making great efforts to reorganize the rapid response team for acute and critical illnesses." Qin Hai put down his cup, his voice steady and powerful. "Specialist doctors are responsible for delving into the deepest aspects of diseases in a single area. But medicine is a net, and there are always some rare diseases and complex injuries that fall into the gaps between specialties."

Qin Hai pointed to the black RRT pager that Lin Ye had in his pocket: "The emergency department used to be regarded as the hospital's 'triage front desk.' But from now on, the RRT is the hospital's special forces. When you encounter physical failure and there is nothing that can be done in the deep waters of the special departments, the emergency department is responsible for sewing the net shut and providing a safety net for the entire hospital."

These words resonated deeply.

This not only voiced the grievances of the emergency department, but also firmly established the new status of emergency RRT in the entire hospital.

Director Zhao nodded in deep agreement.

"Director Qin is right. In the past, when something happened in our ward, our first reaction was to call the internal medicine department and wait for a consultation, which often delayed the most precious rescue time. Today, Dr. Lin has taught us a harsh lesson. From now on, if there's a blue alert in the psychiatry department, we will definitely call RRT immediately!"

Fifteen minutes later, Lin Ye walked out of the director's office.

The hall was still bustling with people, and the noise was incessant.

Lin Ye was greeted by two chief resident doctors who had come down from the general surgery department for a consultation.

In the past, these senior resident physicians or attending physicians in these specialties would look at young emergency room doctors with a sense of superiority that said, "You can only do initial screening."

But today, when the two general surgeons brushed past Lin Ye, their gaze lingered for a second on the black RRT pager clipped to Lin Ye's waist, and then they nodded slightly to Lin Ye very naturally, even with a hint of respect.

The whole hospital knows that this morning, the emergency RRT team rushed up to the eighth-floor closed ward and snatched a patient with malignant syndrome who was about to suffer kidney failure and cardiac arrest back from the clutches of death.

Lin Ye returned a standard nod.

He touched the heavy pager at his waist.

He knew that from this moment on, he was no longer just a frontline doctor in the emergency room.

He has officially become the commander of the "special forces" in the massive fortress of the First Municipal Hospital, ready to cross the barriers and face death at any time.
