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

When the fourth ambulance stopped, the floor tiles in the emergency room were covered in watermarks.

The stretcher wheels creaked as they rolled over the threshold.

"The passenger in the back seat, a woman in her twenties, has an open wound on her left forearm but is conscious!"

"There's an elderly person here, experiencing chest tightness, with blood pressure at 146 or 148!"

The last one to come down was a child.

The boy, about six or seven years old, was held in the arms of the paramedics. He was wrapped in an adult coat, and his face was as white as if he had just been pulled from the water. He wasn't crying; his eyes were open, and raindrops still clung to his eyelashes.

When Nurse Zhao saw that he wasn't crying, she frowned instead.

Where are the child's family members?

The paramedic shook his head: "The scene was chaotic. He was sitting next to the child in the back seat, and we haven't been able to confirm whose child it is yet. He didn't talk much on the way here. When we asked if his stomach hurt, he nodded and then shook his head."

Lin Ye looked up from beside bed number one.

The system message indicated that he had not been given time to catch his breath.

[New case in the red zone: Childhood trauma.]

High-risk: Abdominal organ damage, early stage of hemorrhagic shock.

[Key abnormalities: unusual quietness, abdominal wall ecchymosis, cold and clammy extremities.]

[Risk window: 24 minutes 09 seconds.]

Lin Ye's gaze shifted from the red frame to the child's pale lips.

Children are the easiest to fool in the emergency room.

He might not cry out in pain, nor can he clearly explain where it hurts. His failure to cry when he should is even more frightening.

"Sister Zhao, let the child go into the red zone first."

Nurse Zhao had already taken out the child monitoring cuff: "That's what I was thinking too. Don't be fooled by his quietness, he's too quiet."

The injured woman next to him clutched her arm and cried out, "Doctor! My arm bone is showing! Stitch me up first!"

The old man clutched his chest, saying, "I feel tightness in my chest; I have heart disease!"

Several people in the lobby tried to push forward at the same time, and the security guard held them back with his arms.

Qin Hai stood at the door of the emergency room, his voice drowning out the rain: "The yellow and green zones are separated according to the trauma protocol. If you can shout, don't shout yet; if you can shout, it means you still have strength. The child goes into the red zone, Lin Ye goes with him."

The injured woman, her eyes red with anger, exclaimed, "Why? He wasn't bleeding!"

Nurse Zhao pushed her toward the debridement area: "Because he doesn't have the strength to shout. If you suddenly stop yelling, I'll be the first to push you into the red zone."

The injured woman opened her mouth, but didn't push forward any further.

When Lin Ye took the boy, he realized how incredibly light the child was.

She was a small, curly figure, but there was a purplish-red mark diagonally across her stomach under her clothes, as if she had been severely choked by a seatbelt.

"What's your name?"

The boy's lips moved slightly: "Lele."

"How old are you?"

"Seven years old."

"Does your stomach hurt?"

Lele glanced at him and nodded.

"Where does it hurt?"

The child's hand slowly moved to his upper left abdomen, then withdrew as if afraid of being scolded.

Lin Ye observed the actions: "Sister Zhao, blood pressure, heart rate."

"Blood pressure 88.56, heart rate 148, oxygen saturation 96. Hands and feet are cold."

Jiang Peng followed, holding the record sheet: "Children's blood pressure is already difficult to measure, could it be a problem with the cuff?"

Lin Ye didn't look up: "Retake the measurement, and establish intravenous access at the same time. Don't explain all abnormalities away with 'maybe the measurement was wrong'."

Jiang Peng's face flushed: "I know."

Lin Ye gently pressed on Lele's abdomen.

The child shrank back, but didn't cry out.

There was significant tenderness in the upper left abdomen, and the abdominal muscles were somewhat tight.

He lifted his coat, revealing a shockingly dark seatbelt mark that ran diagonally from his right shoulder to his left abdomen.

"Abdominal ligature marks from the car accident, tenderness in the upper left abdomen, rapid heart rate, low blood pressure, and cold extremities." Lin Ye reported while looking at Qin Hai, "Director Qin, I suspect spleen damage or other abdominal bleeding. It cannot be treated as a common abrasion and placed in the yellow zone."

Qin Hai had already heard: "Bedside ultrasound."

"The general surgery department is over there in room number two," Nurse Zhao said.

Qin Hai turned and called out, "Meng Qingwei!"

From the distant surgical preparation area came Meng Qingwei's voice: "I can't leave. Have the emergency bedside scan done first. Call me immediately if you see any fluid!"

Sun Zhiqiang squeezed over from beside bed number two, his gloves still stained with blood: "Put your head out for me."

He used to be afraid that Lin Ye would cause trouble, but now that he saw the baby's belly, his face darkened.

"Little friend, let me take a look at your tummy with something. No injection needed."

Lele stared at the ceiling without saying a word.

When the probe is pressed down, a gray-white image flickers on the screen.

When Sun Zhiqiang scanned the spleen and kidney recesses, his brows furrowed.

"There is a liquid dark area."

Lin Ye spoke almost simultaneously: "Prepare blood, notify general surgery. Child trauma, suspected abdominal bleeding."

Jiang Peng wrote it down immediately.

Qin Hai glanced at the screen: "Call Meng Qingwei and tell him to bring down the second-line staff. There are no separate night shifts in pediatric surgery, so general surgery can cover for now. If necessary, ask for help from higher-ups."

Nurse Zhao held Lele's little hand: "It's hard to find a vein, and the child's extremities are cold."

Lin Ye squatted down and looked into Lele's eyes: "Lele, I'm going to give you a shot, it might hurt a little. If you're scared, look at my buttons, not the needle."

Lele asked in a very soft voice, "Where's my mom?"

Everything in the emergency room was a beat slower.

The paramedic whispered, "There's a woman stuck in the back seat. Firefighters are still breaking her up. We're not sure if she's his mother."

Lin Ye swallowed those words.

He only said, "We'll get you stable first. Your mother will see you as soon as she arrives."

Lele's eyes reddened, but she still didn't cry.

The system notification flashed again.

[Patient No. 4 in the Red Zone: Entering effective treatment procedures.]

Just as Lin Ye breathed a sigh of relief, the fetal heart monitor in the inner room suddenly sounded a series of urgent alarms.

Shen Ruomei's voice came from inside: "The fetal heart rate has dropped again! Below 90, and it's been like this for half a minute!"

The pregnant woman's younger brother broke down in tears at the door, shouting, "Sister!"

The second injured person was being wheeled to the operating room. Upon hearing this sound, he struggled to lift his head.

"Is she my wife? Doctor! Is she my wife?"

Sun Zhiqiang grabbed the stretcher and shouted, "Don't move!"

Lin Ye stood by the child's bed, looking at the monitors that lit up on both sides at the same time.

A seven-year-old child.

A 29-week-old fetus.

A man with abdominal bleeding who hasn't even gone to the operating table yet.

Qin Hai gripped the walkie-talkie tightly: "Has the anesthesiology team arrived yet?"

The sound of running footsteps came from the doorway.

The anesthesiologist rushed in carrying a case: "We're here!"

The system taskbar popped up briefly in Lin Ye's field of vision.

[Currently in the red zone: four players.]

[Incomplete and invalid transition: No. 3 and No. 4.]

Lin Ye looked at the fetal heart monitor, then at Lele's increasingly pale lips.

There were no extra staff in the emergency room.

Every alarm call is part of a race to get a doctor.
