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

The emergency room was bustling with noise, but Zhang Mei's hand holding her phone was trembling uncontrollably.

She dialed the number of her caregiver, Aunt Wang, with trembling hands; even her voice trembled.

"Aunt Wang, what's been going on with my mom at home these past few days? How's her appetite? Are her bowel movements and urination normal?"

The caregiver's somewhat evasive voice came from the other end of the phone.

"Sister Zhang, the old lady hasn't had much of an appetite these past few days. Yesterday at noon and in the evening, she only drank half a bowl of porridge, and she's been sleeping all day. I couldn't wake her up no matter what I did. I thought she was just feeling drowsy, so I didn't dare disturb her..."

"You're pooping or peeing!" Lin Ye sternly interrupted her, his voice close to the phone's microphone. "How often do you change your diapers? What color is your urine? Does it smell?"

"Oh dear, doctor, elderly people like this are bound to have smelly diapers." The caregiver was startled by Lin Ye's tone and quickly recalled, "But these past two days the smell has been particularly strong, a pungent ammonia smell, it's nauseating. And the urine in the diapers is very yellow, like strong tea, and a bit cloudy. I thought the old lady was just dehydrated and had some internal heat..."

Lin Ye straightened up, his gaze instantly turning cold.

The puzzle is now complete.

"Tang Wen, get her to the emergency room immediately! Put her on ECG monitoring right away, establish two IV lines, and start with 500 ml of normal saline for rapid volume expansion!" Lin Ye turned and gave the order. "Go to the catalysis lab right away; I need to see the blood gas analysis and urinalysis results as soon as possible!"

Tang Wen was completely impressed by Lin Ye's serious demeanor. She pushed off the brakes of the wheelchair and rushed the old lady into the emergency room.

Zhang Mei panicked completely, her high heels making a messy sound on the tiles as she stumbled and followed behind.

"Doctor, what happened to my mom? She didn't have any broken bones, so why does she need to go to the emergency room?"

"Cloudy urine, pungent odor, extreme drowsiness, and complete loss of appetite." Lin Ye quickly explained the condition to the family as he strode towards the emergency room. "This is a very typical case of severe urinary tract infection! Moreover, the infection has breached the local defenses, and the bacteria have entered the bloodstream. Your mother's current 'legs giving way and falling' and 'dropped blood pressure' are because she is on the verge of septic shock!"

Zhang Mei was struck dumb, frozen outside the emergency room door.

"Shock? But...but my mom doesn't even have a fever! I touched her forehead this morning before she left, and it wasn't hot at all!"

"This is the most frightening and deceptive aspect of how infections among the elderly can be so dangerous."

Lin Ye stopped and looked back at the middle-aged woman who was on the verge of collapse due to balancing work and retirement. His voice was less stern and more helpless.

"A young person's immune system is like an elite force, sounding the alarm for high fever as soon as it encounters bacteria. But an elderly person's immune system has long since declined. Faced with deadly bacteria, their body doesn't even have the strength to fight off 'fever.' They won't cry out in pain or have a fever; they'll just become extremely silent and lethargic until their internal organs completely stop functioning due to lack of blood."

"What about that wrestling match just now..."

Zhang Mei's tears welled up instantly.

"That was because her blood pressure dropped sharply due to septic shock, leading to insufficient blood supply to the brain." Lin Ye looked at her. "That fall was her last silent cry for help before her body completely collapsed."

Ten minutes later.

The bedside monitor in the emergency room emitted a regular "beep" sound.

Tang Wen, holding two newly printed lab reports, jogged over to Lin Ye's side.

"Teacher Lin, you were absolutely right..."

Tang Wen's voice was trembling.

Lin Ye took the test results.

[Blood gas analysis: Lactate (Lac) 5.2 mmol/L] (Normal value is usually less than 2.0. A surge in lactate indicates severe hypoxia in the body tissues, confirming shock!)

[Urinalysis: White blood cells (WBC) +++, filling the entire field of view] (The urine is full of pus cells that died from infection!)

[Complete Blood Test: White Blood Cell Count 2.1 x 10^9/L] (Normal range 4-10. The white blood cell count has decreased instead of increased, indicating that the elderly person's immune system has been completely overwhelmed by bacteria and is powerless to fight back!)

"Typical urosepsis complicated by septic shock." Lin Ye slapped the lab report onto the medical record folder. "Immediately administer imipenem (Tianan), the highest level of broad-spectrum antibiotic to suppress the bacteria! Continue fluid resuscitation, and prepare to request an EICU consultation and admission!"

Tang Wen looked at the old lady on the hospital bed who was still quiet and didn't even utter a groan. Her back was completely soaked with cold sweat.

If she had simply followed the standard procedure, glanced at the normal X-ray, prescribed Yunnan Baiyao for the old lady, and sent her home...

Tang Wen dared not think any further.

When Zhang Mei got home from get off work tonight, she was sure to see a cold, wet body covered in septicemia.

Tang Wen will face one of the most devastating medical malpractice incidents and a moral dilemma in her career.

Emergency room outpatient clinics are never just a superficial assembly line.

Behind those seemingly insignificant "falls," "dizziness," and "loss of appetite" often lurks a gaping abyss.

Outside the emergency room.

Zhang Mei watched as the nurse hung bags of clear liquid and antibiotics by her mother's bedside. Looking at the waveforms on the monitor that she couldn't understand but could sense were deadly danger, her legs suddenly went weak, and she collapsed onto a plastic bench in the corridor.

My phone vibrated again, the screen flashing "General Manager," urging me to attend the important meeting at 10:30.

Zhang Mei did not answer.

She covered her face with her hands, tears streaming down her face through her fingers, and let out a suppressed and painful sob in the noisy emergency room.

She hated the irresponsible caregiver, but she hated herself even more.

If she could spare ten minutes each night, even just to glance at the diaper her mother had changed.

If she had just asked her mother one more question about why she wasn't eating... perhaps things wouldn't have escalated to the point of shock.

In the fast-paced gears of modern society, this care gap caused by "being too busy with work and having to pay for care" is like an invisible blunt knife, silently reaping the lives of those silent elderly people.

Lin Ye stood behind the glass door of the emergency room, watching Zhang Mei cry, but did not go out to comfort her.

In the emergency room, doctors can use antibiotics to kill bacteria in the blood and use vasopressors to stabilize collapsing blood pressure, but they can never prescribe a single medication to heal the most helpless family rifts of our time.
