[Chapter 12 Cardiovascular Ward 07]

At 6 o'clock in the afternoon, the students had their own dinners, and then came to the ward where Yue Xingwen was, and handed over the "homework" that had been assigned to everyone back to Yue Xingwen's hands.

Yue Xingwen carefully summarized the homework that everyone handed in, and sorted out the experiences of the five deceased before their death.

Bed 5, 55 year old female, cheerful personality. Her son and daughter-in-law are both teachers. She visited her in the hospital yesterday afternoon. It was originally agreed that she would go through the discharge procedures today, and the old lady is recovering well. The family members came to the hospital this morning and heard that she died unexpectedly. They refused to accept the fact. They cried a lot in the ward and argued with the doctors for a long time.

Yue Xingwen handed the information to Liu Zhaoqing, who frowned and said, "This old lady died so wrongly. She could have been discharged from the hospital today, but she suffered a heart attack last night. No wonder the family members couldn't accept it."

Yue Xingwen continued: "The family members of the 80-year-old man are very calm. He is in critical condition and has been hospitalized six times. His family members should have been psychologically prepared and quickly accepted the fact that the old man died and has Take the body away."

Liu Zhaoqing asked, "The 60-year-old old lady had an operation scheduled for three days later, but unfortunately, she died before the operation. What did her family say?"

Yue Xing Wen said: "Her family members are out of town and have not had time to claim the body. The remaining two grandfathers, 70 and 77 years old, have already undergone surgery. The family members should be more uncomfortable. They thought the surgery was successful. , and the result was sudden postoperative death.”

Liu Zhaoqing sighed: "Alas, sudden illness in the hospital, death in the middle of the night is very common, I have encountered several times when I was on the night shift. But if it is true, as you said, someone is secretly doing something, it will be completely different. ."

Yue Xingwen nodded: "So, we have to find clues as soon as possible."

At 7:30 in the evening, most of the doctors had already left work, and the students began to pretend to be sick as instructed by Yue Xingwen.

First, Liu Xiaoxiao, who was in bed 4, pressed the call for help. When the nurse came to the bed, she huddled on the bed and rolled while shouting, "My stomach is so uncomfortable, did I eat something bad? It hurts..."

The thin girl was sweating coldly on her forehead, and her face was pale as she pressed her stomach. The nurse was startled and hurried to the doctor on duty.

As soon as the doctor walked into her ward, the boys in the chemistry department also began to pretend to be sick. The boy was already sick, shrank on the bed and shivered, while pressing his heart and groaning in pain: "My heart hurts so much, it's so uncomfortable... ..." Zou Yuhang, who was in the same ward, rushed to the doctor's office nervously: "Doctor, my patient has a heart attack, go and see!"

The doctor who had just eaten was called away by him.

Then, Qin Lu also cooperated with the acting, pretended to have a headache, and called the last doctor on duty away.

The condition of the patients in the ward was frequent, and the three doctors were transferred away from the mountains. Yue Xingwen and Liu Zhaoqing had been walking near the doctor's office. Seeing that all the doctors were called away, Yue Xingwen immediately gestured to Ke Shaobin in the distance.

Ke Shaobin understood, sneaked into the doctor's office under the cover of Yue Xingwen, opened the doctor's computer and started to decipher the code. Liu Zhaoqing and Yue Xingwen guarded the left and right corners of the corridor to prevent doctors or nurses from coming.

Ke Shaobin was sitting in front of the computer, his slender hands quickly tapping the keyboard, his expression extremely serious.

Lines of complex codes appeared on the computer screen. After a while, Ke Shaobin successfully invaded the system. He quickly raised his right hand, placed his laptop next to the desktop, and started wireless data transmission.

A blue [Data transfer...] reading box appears on the computer.

Seeing that the transmission was at 80%, there was a sudden sound of footsteps in the corridor on the right. Liu Zhaoqing saw a nurse pushing a treatment car over, and hurriedly stepped forward to stop the other party, smiling: "Hello nurse, please ask me, tonight I will Do I still need an injection? I am Liu Zhaoqing, a 16-bed patient."

The nurse glanced at the name on his wristband, flipped through the doctor's order on the treatment car, and said, "You don't need injections tonight, go back and have a good rest. For the specific treatment plan, you will ask your doctor in charge during your rounds tomorrow morning. ."

Hearing the conversation in the corridor, Ke Shaobin was so nervous that his palms were sweating.

The data transmission finally became 100%, and Ke Shaobin immediately exited the system, raised his right hand, retracted the laptop into his palm, quickly slipped out of the office, and turned and left with Yue Xingwen.

When Liu Zhaoqing saw them approaching, he smiled at the nurse and turned sideways to make way: "Thank you, beautiful lady."

The three walked along the corridor towards the ward. When they passed the nurse station, they found a large trash can marked "medical waste" at the end of the aisle next to the nurse station. Yue Xingwen looked at Liu Zhaoqing and pointed to the trash can: "Senior brother, do you want to go through it? If my inference is true, the evidence that the murderer didn't have time to deal with might be in the trash can."

Liu Zhaoqing nodded: "Well, let's go."

The three sneaked up to the nurse's station.

Since the other students were still trying their best to hold the doctors and nurses, there was no one nearby. Ke Shaobin stood guard at the entrance. Yue Xingwen and Liu Zhaoqing stole two pairs of medical gloves from the nurse station and put them on. They opened the trash can and started looking for clues. .

Gauze, syringes, these have no reference value, the key lies in the medicine bottle.

Yue Xingwen pulled out all the medicine bottles and infusion bags, and Liu Zhaoqing checked carefully next to him: "Saline, glucose, antihypertensive drugs, blood transfusion drugs... and epinephrine, which should have been used when rescuing patients... ..." He passed the bottles of medicine that he turned out one by one, and then shook his head: "It's all common drugs, nothing unusual."

Although it was a waste of time, Yue Xingwen was not frustrated, and said softly: "There are no traces left here, which means that the murderer did not change the medicine at the nurse's station. The possibility of the nurse committing the crime is relatively low, and the scope of investigation can be further narrowed."

The three returned to the ward and sat down, and after a while, several classmates knocked on the door and came in.

Yue Xingwen's eyes swept over everyone, and his voice was gentle: "Everyone has worked hard, find a place to sit, let's have a meeting and discuss it first."

Zou Yuhang quipped: "It feels like a class meeting, Xingwen is our squad leader?"

Yue Xingwen smiled at him and looked at Ke Shaobin: "Open the data and see the conclusions of the doctors."

Ke Shaobin raised his right hand, and the computer icon in the palm of his hand turned into an ultra-thin notebook. The other students were very envious of the computer department's reward - it was a laptop and an intelligent robot. The computer department is really rich!

Ke Shaobin opened the patient data folder in the laptop and rotated the screen to Yue Xingwen. Yue Xingwen quickly swiped over the disease course records that she had read yesterday, directly opened the newly added "Death Case Discussion" section, and greeted Liu Zhaoqing: "Senior brother, you are more professional, so come and have a look."

Liu Zhaoqing moved a stool and sat next to him, looking at the screen and saying, "These are the analysis of death cases recorded after the doctors' meeting in the afternoon. The cause of death of the five people is all acute myocardial infarction. The detailed time of death and rescue records, from the rescue records, the doctors did their best, but unfortunately they were not rescued."

Yue Xingwen tore off a piece of white paper from the dictionary and said as he sorted it out—

"15, 77-year-old male, died at 1:10 am; 24, 80-year-old male, died at 1:20 am; 5, 55-year-old female, died at 3:30 am; 33, 60 50-year-old female, died at 3:40 in the morning; 50-year-old male, 70 years old, died at 5:00 in the morning." He looked up at everyone: "Have you found the pattern?"

Everyone looked at each other for a while.

Zou Yuhang raised his hand first: "Is there a problem with the time of death?"

Ke Shaobin analyzed: "These hospital beds sound quite messy, but after Xingwen arranged the death time, the patient's death seems to be divided into three stages, two died at 1:10, 1:20, and 3:30. Two dead at 3:40, one dead at 5?"

The other classmates suddenly realized, but followed with blank expressions: "What's the point of this?"

Yue Xingwen used a pen to draw a circle on the paper: "The murderer's crime time, and the path of movement."

Hearing the word "murderer", a group of students froze at the same time, Zou Yuhang's face was pale, and his lips couldn't help trembling: "Murderer, murderer? You mean, these five patients were killed by someone?!"

"That's right." Yue Xingwen analyzed seriously, "The additional question allows us to find the real cause of death of the patients in the ward. If there is no human factor in their death, then the answer to this question is 'acute myocardial infarction'. Do you think, 30 The additional questions for points, will it be so simple to give points directly to everyone?"

Heart disease patients, acute myocardial infarction death, everyone is easy to think of. The doctors' death case analysis is also written in this way, which is definitely not the correct answer.

"I personally believe that the deaths of the five patients were caused by the same murderer." Yue Xingwen paused, then turned to look at Liu Zhaoqing, "Senior brother, is there any medicine that can cause a heart attack to a patient with a heart attack?"

"Vascular constricting drugs." Afraid that everyone would not understand, Liu Zhaoqing lightly clenched his left hand into a fist again, representing the heart, and his right hand gestured on it to explain: "You can understand this, coronary heart disease patients have narrow blood vessels on the surface of the heart, and the river is congested. Doctors usually use drugs that relax and soften blood vessels to unclog the river. But if they do the opposite, give them drugs that tighten blood vessels…”

His two fingers suddenly clamped: "The originally narrowed blood vessel is blocked by the drug so tight, isn't it?"

Everyone is not a medical major, but Brother Liu's explanation and gestures are easy to understand. The patient already has stenosis of the blood vessels. Continued use of vasoconstrictor drugs can easily lead to vascular blockage, making the patient unknowingly and unknowingly, and suddenly die of myocardial infarction.

- All they have to do is find this person, and that's the answer to the extra question.

Ke Shaobin put forward another conjecture: "Some highly toxic substances can kill these people quickly, right? If someone adds a highly toxic substance to their medicine, this injection can kill five people?"

Yue Xingwen nodded: "It is true that the possibility of poisoning cannot be ruled out."

Qu Weiwei's face turned pale, she stroked her curly hair and asked, "But who would do this? What's the reason for doing this? What kind of hatred do the five patients have with him?"

Zou Yuhang guessed: "From the information we have compiled, the five patients do not know each other at all, so the probability of offending the same murderer is very small, right? Could it be a perverted doctor in the hospital doing human experiments? Before "Escape from the Laboratory" "That level is when a drug in the lab goes wrong and the monkey mutates."

Yue Xingwen also thought about this possibility. He pondered for a moment and pointed out some doubts: "In the laboratory class, researchers are experimenting with antiviral drugs on animals. If the cardiovascular ward is also experimenting with new drugs, Liu Senior brother should be able to find out from the case, right?"

He looked at Liu Zhaoqing, who touched his chin, opened the diagnosis and treatment records of several patients in the laptop, pointed to the medicines on it and said, "I read the diagnosis and treatment plan yesterday, and there is no problem. What the doctor prescribes to the patient is clinical It is a very common drug for coronary heart disease control. We also turned over the trash can just now and found no suspicious drugs. It should not be a doctor doing an experiment."

Ke Shaobin said: "Analysis and analysis, Xingwen's inference is the most reasonable. There is a latent murderer in the ward who is committing the crime. He secretly changed the medicine, or added a high poison to the medicine, killing five consecutively. patient."

The faces of the classmates were a little ugly.

Is this really reasoning to find a murderer during the day, and a thriller battle royale at night?

Everyone looked at Yue Xingwen for help, and Zou Yuhang said, "Xingwen, do you have any clues about the murderer?"

Yue Xingwen cleared his throat and concluded, "First, many serial murderers have common characteristics among the deceased, for example, they are all long-haired women, all young men, etc. However, in our case, the five deceased persons were of different ages, identities, genders, and even the priorities of their illnesses. This shows that the murderer committed the crime by randomly selecting targets without any special direction.”

Random kills? This is very likely to happen to everyone randomly, right? Everyone's scalp was numb when they heard it.

Zou Yuhang couldn't help but complain: "Wouldn't it be more difficult to reason about killing people randomly?"

Yue Xingwen said calmly: "It's not particularly difficult. Because the murderer of this case is by our side, and there is a fixed range of suspects. We can use the exclusion method to investigate one by one."

Liu Zhaoqing quickly reacted: "That's right! The patient died last night. The time of death includes one, three, and five in the morning. There are three different time periods. The door of the ward is locked at night, and outsiders cannot enter, which means the murderer Was in the ward all night last night!"

Yue Xingwen nodded: "Except for the 10 of us and the 5 people who have been killed, all the doctors, nurses, and patients on duty who stayed in the ward last night are suspects. Let's look at this picture I drew first. ."

He picked up the paper he had drawn for a long time and showed it in front of everyone.

The students were surprised to find that he had drawn a strange ring-shaped trajectory on it.

Yue Xing Wen said: "The five patients died at 1:10, 1:20, 3:30, 3:40, and 5:00. The order of murder by the murderers was from 15 beds, 24 beds, and then to 5 beds, 33 beds, and finally 50 beds, this is the trajectory of the murderer last night."

He used a pen to draw three arrows on the paper, representing the murderer's moving route in three time periods, followed by: "According to the analysis of the graphic trajectory and the inference of criminal psychology, the murderer will first choose the closest one to himself when committing a crime. It is convenient for people to start, and after the crime is successful, they will choose a hospital bed far away from themselves. Then, the murderer is very likely to be—”

He drew an intersection of the three moving trajectories and locked the two wards at the intersection.

The students stared at Yue Xingwen in amazement.

After a while, Liu Zhaoqing gave a thumbs up: "The more detective, you are awesome!"

Zou Yuhang looked in admiration: "Dude, aren't you from the Chinese department, why do you still understand trajectory analysis?"

A smile appeared in Yue Xingwen's eyes: "I have a good friend in the mathematics department, and he taught me the reasoning method of data analysis. I think if he encountered this problem, he would definitely find the time of death quickly. , movement trajectory and the location of the murderer.”

Everyone: "..."

Following a squad leader like Yue Xingwen, can you get points by laying down and winning?
