Chapter 129: Air Syringes

"You haven't answered my question yet." Fu Qingyuan kept his previous movements unchanged, with a hint of a shallow smile in his deep eyes.

Mo Zishu replied with Fu Qingyuan's faint smile and said, "Yes." ”

Fu Qingyuan, who got the answer, lowered his head and chuckled, his thin short hair hanging down on his forehead.

"Rest, tired." Mo Zishu said, motioning for someone to get her the bed down, and closed her eyes to rest.

"Huh." Fu Qingyuan laughed lightly, and finally shook his head helplessly and got up and put Mo Zishu's hospital bed down.

"Something called me." Fu Qingyuan walked to the sofa and said a word, then raised his feet to the sofa and sat down.

Only one wall lamp beside Mo Zishu's bed was left in the huge hospital bed, which was soft and warm.

The next morning.

Magnolia is very happy today, it should be said that she has been very happy since last night, because Mo Huaheng, who has always slept in a separate room with her, did not mention this matter last night, and took the initiative to return to the master bedroom to rest.

She got up early this morning, and sat on the bed in disbelief, and after looking at Mo Huaheng's face for a while before believing that it was true.

"Ma'am, won't you rest for a while?" Guanhehai was a little surprised to see Magnolia, who was wearing a casual suit, sitting in the hall so early.

"No, get up early, I'll have to go to the hospital later, Zishu." Magnolia smiled slightly, shook her head, and put down the white porcelain cup in her hand.

Guanhehai nodded clearly, although he still heard the hesitation in Magnolia's mouth, but he could feel that something in it was changing little by little.

"Uncle Guan, is the soup ready?" Magnolia suddenly remembered that last night she told Guanhehai to get up early today to make soup.

"Come on, ma'am, go wash up first." Guanhehai replied with a smile, his silver-white hair was meticulously combed upwards, and he looked very energetic in a black housekeeper's uniform with a white shirt.

"Okay." Magnolia responded, got up and walked towards the second floor.

At the moment when Magnolia got up and went upstairs, she didn't notice that a smile of relief flashed in Guanhehai's old eyes, and then it became cloudy to hide that shrewdness.

People's Hospital

"Is Zhang Da awake?" Yan Heng rushed to the People's Hospital early in the morning and questioned the police officers who had been guarding outside the intensive care room.

"Report to Officer Yan, Zhang Da woke up once at 7:14, the doctor went in to check for ten minutes, and Zhang Da fell asleep again." The answer to Yan Heng was a male police officer who was full of energy, with a straight waist and a serious facial expression with a hint of funny.

Yan Heng was stunned for a moment, then nodded and said 'OK', and stood outside the glass of the intensive care unit and looked at Zhang Da lying on the hospital bed.

"Hello, I am a special nurse for patient Zhang Da, I need to change the dressing for patient Zhang Da now, please open the door with two police officers." A female voice came from the door of the intensive care unit.

Yan Heng looked over and saw the female nurse holding the tray in her hand take out her work card and show it to the two police officers guarding the door of the intensive care unit, and then the two police officers nodded, opened the door, and gave way to the female nurse.

Yan heng frowned, remembering what the police officer said just now, Zhang Da woke up at seven o'clock, and then the doctor came over to check, and then.

Yan Heng opened the sleeve of his wrist and looked at the watch on it, seven fifty.

"When the doctor came just now, did he change the dressing for Zhang Da?" Yan Heng hurriedly asked the police officer next to him another question.

"Report to Officer Yan, yes, it was changed by the attending doctor." The officer was still yelling loudly.

"Oops." Yan Heng's eyes immediately became ruthless, and he quickly rushed to the door.

The two police officers guarding the door didn't know why, so they could only let Yan Heng break in.

The female nurse who had just walked to the edge of Zhang Da's bed heard the movement, her eyes became obscure, but the speed of the movement in her hand did not decrease by half a minute, she pushed the syringe in her hand up, and then inhaled it, and there was nothing in the needle.

As soon as the tip of the needle pierced Zhang Da's skin, Yan Heng appeared in front of the female nurse.

"What are you doing?" Yan Heng frowned, looking at the female nurse in front of him with a grim look.

"Officer, I'm changing the dressing for patient Zhang Da." The female nurse was not only frightened in the face of Yan Heng, but actually smiled at Yan Heng, and then slowly pushed the syringe in her hand.

"If you don't take the needle out now, I'll kill you right away." Yan Heng looked at the female nurse, but saw that there was no liquid in the needle she injected, although he was very puzzled, he still felt that something was wrong, and took out a gun from his waist and aimed it at the female nurse's head.

The female nurse obviously didn't expect the man in front of her to be so ruthless and straight, looking at the black gun in the hand of the man in the police uniform, her heart trembled, and the syringe in her hand was pushed by nearly four millimeters, and she didn't continue to move.

"I'll give you three seconds." Yan Heng slowly moved forward, his hand holding the gun getting closer and closer to the female nurse.

“3”

“2”

When the female nurse heard that the man in front of her was real, she wanted to push the syringe directly to the end, but it was too late.

"Ahh

The female nurse was shot in both hands by Yan Heng, the bullet directly penetrated the bones of the palm and then shot into the palm of the other hand, the bright red blood rolled down to the white sheets, the female nurse screamed, her eyes split, and she looked at Yan Heng with a strong hatred in her eyes.

Outside, police officers who heard the gunshots quickly rushed in and subdued the female nurse who had fallen to the ground.

"Call the doctor." Yan Heng put away the gun, put on gloves and pulled out the needle that had not been removed, and saw that Zhang Da, who was still asleep, had a bad face, and immediately shouted.

Yan Heng looked carefully at the fact that there was indeed nothing in this needle, and there was just air, air? Murderous injection of air?

"Officer Yan, the doctor is here." The police pulled the doctor and ran to Yan Heng.

"What, what's wrong, what's going on?" The doctor asked for some reason, a little out of breath.

"She injected this into Zhang Da's veins." Yan Heng pointed to the female nurse who was subdued, and then took the syringe he had just taken off to the doctor.

"Officer Yan, there's nothing." A police officer said suspiciously, looking at the empty syringes.

The doctor also looked over with Yan Heng's hand, but in just a few seconds, the doctor's face changed drastically.

"Oops." The doctor hurriedly broke free from the police officer's hand and ran towards Zhang Da's hospital bed.

"Quick, hurry up and rescue urgently." The doctor saw that Zhang Da had begun to breathe rapidly and panting, and even had signs of cyanosis, and his heartbeat stimulated his nerves like thunder, and pressed the call bell at the head of the bed.

Within a minute, a group of nurses and doctors broke in, and then pushed Zhang Da on the hospital bed and left.

It didn't even take five minutes.

"Officer Yan, what's wrong? Could it be that what she injected is something that only doctors can see? The officers were all puzzled.

Yan Heng shook his head and said, "Take her back." Then he walked to the window and took out his mobile phone to make a call.

"Hey, what's wrong?" Jing Chen's anxious voice rang on the phone.

"What happens if you inject air into your blood vessels?" Yan Heng said straight to the point, he felt that this kind of modus operandi was very familiar, but he couldn't remember it for a while, this was a case that the professor talked about in class when he was studying in the criminal investigation department of the university.

"Oh, it depends on the amount of injection, if you inject air into the blood vessels, more than 5mml (in fact, I don't know the specific data, Baidu is not accurate, if it is not accurate, please don't say it) There is a great possibility of causing gas embolism, that is, air embolism, the gas entering the pulmonary veins passes through the left atrium and left ventricle with the blood flow, and finally flows into the arterial branches of the whole body, blocking the arterial branches, causing ischemia of the corresponding organs, especially the brain and myocardium, and in severe cases, it can obstruct the blood flow back to the left heart. Severe circulatory collapse can lead to immediate death. Air embolism in the pulmonary circulation or on the right side of the heart is iatrogenic and can easily enter the central vein if the needle or catheter lumen is not closed in time when central venous puncture is done, and the negative pressure in the pleural cavity increases during inspiration. When the needle is removed or the catheter is replaced, air can also be sucked into the vein, flow into the right atrium, and enter the pulmonary artery through the right ventricle, causing pulmonary embolism, which can lead to pulmonary infarction. Jing Chen'an spoke for three minutes as if he was reciting it.

"Okay, I got it." Yan Heng hung up the phone directly after listening to Jing Chen'an, and at the same time he also remembered that the professor was talking about that case when he was in class, that case was a normal person who was injected nearly fifty milliliters of air into a vein, which directly led to death, and the cause of death was cerebral embolism.

Sure enough, their guess yesterday was not wrong, and there were really people who wanted to put Zhang Da to death, and all this happened too quickly.

Zhang Da was pushed into the rescue room, and Yan Heng and the other police officers were waiting outside the rescue room.

Tong'an Hospital.

"Yan Heng called me just now, I guess someone did something to Zhang Da." Jing Chen'an, who was disturbed by Yan Heng to sleep, hung up the phone and came directly to the hospital to see Mo Zishu, he booked a hotel near the hospital last night.

Mo Zishu was pushed to do various examinations very early, so it didn't take long for her to return to the ward at this time, but fortunately, Fu Qingyuan was with her throughout the whole process.

"It's slower than you think." Mo Zishu nodded, not surprised at all.

"Also, anyway, it was the best time to do it in the middle of the night last night." Jing Chen'an echoed.

"By what means?" Mo Zishu asked.

"Air injection, this trick is amazing." Jing Chenan said.
