Chapter 1571

See Ling Ruonan very aggrieved to shed tears there, Wu Yue is low head, a pair of dejected look, Luo Ziling finally can't bear.

He wiped his hands on the apron, and then took out a paper towel from his pocket and wiped away the tears on Ling Ruonan's face.

"Mom, why don't we have a good chat after dinner later," Luo Ziling said softly. "Wu Yue and I will tell you everything. You can make a decision after listening. Where do you think needs to be remedied, you decide. "

"OK," Ling Ruonan took a paper towel, wiped his tears, and then told Wu Yue, "you go out first and report anything at any time."

"Yes," Wu Yue nodded and went out.

Luo Ziling and Ling Ruonan continue to be busy in the kitchen, but they don't say anything more. In the kitchen, except for the sound of the range hood, there are only the sounds of cutting and frying. The atmosphere is very dull, which makes Ling Ruonan feel very depressed and Luo Ziling also feels very uncomfortable.

However, both mother and son don't know how to break the depression.

When Luo Ziling and Ling Ruonan think of anger, there is chaos in the VIP ward of Yanjing people's hospital about three kilometers away from where they live.

Emergency, let everyone are confused.

Yang Yunzhong, a VIP patient who lived here for nearly a month and whose injuries tended to be stable, suddenly deteriorated. The medical staff put into the rescue at the first time, but in the end, the rescue was not as good as before. The line indicating the heartbeat on the ECG monitor was slowly straightened.

After rescuing for more than an hour, the hospital finally declared the patient dead.

When Yang Yunzhong's condition deteriorated, the hospital immediately called the police, and the police arrived at the hospital as quickly as possible to control the floor where Yang Yunzhong lived. Most of the hospital leaders also arrived at the ward in a very short time.

After Yang Yunzhong's death was announced, the doctors on the scene wrote the rescue case completely and handed it to the police.

The doctor in charge of Yang Yunzhong also reported the cause of Yang Yunzhong's death to the hospital leaders.

"A large amount of potassium chloride was injected into the patient, causing cardiac arrest and death." This is written in the case by the doctors involved in the rescue and the cause of death reported by them.

It is because of the discovery of artificial injection of high concentration of potassium chloride, so the hospital first alarm.

Before Yang Yunzhong was declared dead, the police at the scene found the abnormal situation.

A nurse in this ward was found unconscious in the dispensing room and her work clothes were stripped.

After the police found out this situation, immediately transferred to the ward monitoring.

Monitoring showed that the nurse entered the dispensing room and came out soon.

Because the nurse was wearing glasses, a mask on her face and a hat on her head, no abnormal situation could be seen from the monitoring.

The nurse pushed a car out of the dispensing room and went directly into the ward where Yang Yunzhong lived.

There are bodyguards guarding the door of the ward where Yang Yunzhong lives, but they don't have any interrogation of the nurses.

The nurse went in and came out in about a minute.

When she came out, she also said two words to the bodyguard at the door.

What to say, no audio acquisition monitoring system can not distinguish.

After the nurse left with the dressing cart, she walked to the other ward and disappeared in the monitoring area, but soon appeared in another monitor.

She walked to the ward next to the elevator, looked back at the direction of the monitoring, and then put the dressing car at the door of the ward, and people walked to the elevator direction. When the elevator door opened, she walked in.

Police continued to follow up the monitoring inside the elevator and found that the nurse had gone to the washing room in another ward and never appeared again.

Police officers immediately went to the washing room and found that there was a set of changed nurses' working clothes in the washing room, but no one was in it.

After inspecting the washing room, the police found that the bathroom was next to the washing room.

After discovering this situation, they continued to check the monitoring and found that several men and women were in and out of the bathroom for a period of time after the nurse disappeared.

After looking back and forth at the monitoring screen, the police finally found that the number of people in and out of the bathroom was different, and there was one more person out of the bathroom than in the bathroom.

In other words, the "nurse" left the bathroom.

After making a rigorous comparison, the police targeted a woman in a pink down jacket, a woolen hat and a mask on her face.

The woman left the bathroom and took the elevator down again.

But it is depressing that the monitoring of the elevator is broken, and there is no monitoring video left.

After checking all the surveillance videos in the hospital, the police still couldn't find the woman again.

The surveillance video of the neighborhood was also called. The police used a large number of personnel to check all the surveillance videos in the neighborhood, but they still failed to find any clues. In other words, the woman just disappeared.The situation is also very clear, this is a man-made murder, is outside disguised as a nurse, injected a large dose of potassium chloride on Yang Yunzhong's body, resulting in Yang Yun's sudden cardiac arrest and death.

During the rescue, the medical staff also made electrolyte and other biochemical tests for Yang Yunzhong.

The serum potassium concentration was as high as 18.7 mmol l l, which was several times higher than the normal upper limit of 5.5 mmol l L.

With hyperkalemia synchronous, there are many indicators abnormal.

Originally, the biochemical indexes in Yang Yun were basically normal, and the latter abnormality should be the result of hyperkalemia.

The massive injection of potassium chloride led to the death of Yang Yunzhong, which was also recognized by the police. However, the medical staff and the police were puzzled why Yang Yunzhong did not respond to the injection of potassium chloride.

You know, when high concentrations of potassium ions are injected into the blood vessels, the pain can't be tolerated at all.

The patient must have struggled and called, but Yang Yunzhong did not have the slightest such performance, and was very calm all the time.

It's not very scientific.

Police also took his blood and sent it to the criminal identification center to test for any abnormal components in the blood.

After death, the red blood cells in the body begin to destroy.

In other words, after the death of the patient, the blood potassium concentration in the patient's body rises rapidly. The potassium concentration in red blood cells is 30 to 40 times higher than that in plasma. The blood potassium concentration detected after Yang Yunzhong's life lost disease has lost its significance.

However, the police detected an anesthetic component in the patient's body, and the existence of barbiturates, which can work in an ultra short time, explained the doubts in everyone's mind.

The woman disguised as a nurse injected Yang Yunzhong with potassium chloride solution mixed with this highly effective anesthetic called thiopental sodium, or injected him with anesthetic first and then potassium chloride. In this way, Yang Yunzhong quickly fell into anesthesia without any reaction.
