Chapter 1571: cause of death

Seeing Ling Ruonan shed tears in aggrieved situation, while Wu Yue lowered his head and looked dejected, Luo Ziling finally couldn't bear it.
He wiped his hands on the apron, then took out a paper towel from his pocket, and wiped away the tears on Ling Ruonan's face.
"Mom, or else, after dinner, let's have a good chat," Luo Ziling sighed softly, "Wu Yue and I will tell you everything, and you can decide after listening to it. What do you think needs remedy? Yes, you decide."
"Okay," Ling Ruonan took the tissue, wiped away the tears, and then told Wu Yue, "You go out first, and you can report anything at any time."
"Yes," Wu Yue nodded and walked out.
Luo Ziling and Ling Ruonan continued to be busy in the kitchen, but they did not say anything. In the kitchen, except for the sound of the cooker hood, only the sound of cutting vegetables and cooking, the atmosphere was very dull, which made Ling Ruonan feel very depressed. , Luo Ziling also felt uncomfortable.
It's just that neither mother and son know how to break this dullness.
When Luo Ziling and Ling Ruonan thought of anger, the VIP ward of Yanjing People's Hospital, about three kilometers away from where they lived, was in chaos.
The unexpected incident has made everyone confused.
Yang Yunzhong, a VIP-level patient who has been living with them for nearly a month, and his injuries stabilized. Suddenly, his condition deteriorated. The medical staff immediately put in the rescue, but in the end the rescue was too late. The line on the ECG monitor that indicated the heartbeat Straighten slowly.
After more than an hour of rescue, the hospital finally announced that the patient was dead.
When Yang Yunzhong's condition deteriorated, the hospital immediately reported to the police, and the police rushed to the hospital as quickly as possible and controlled the floor where Yang Yunzhong was staying. Most of the leaders of the hospital rushed to the ward in a short time.
After announcing the death of Yang Yunzhong, the doctor on the scene wrote the rescued case in full 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 leadership.
"The patient was injected with a large amount of potassium chloride and died of cardiac arrest." This is what the doctors involved in the rescue wrote on the case and the cause of death they reported.
It is precisely because it was discovered that a high concentration of potassium chloride had been artificially injected, so the hospital called the police the first time.
Before Yang Yunzhong was declared dead, the police who came to the scene discovered the abnormal situation.
A nurse in this ward was found unconscious in the dispensing room, and her overalls were stripped away.
After the police discovered the situation, they immediately checked the surveillance in the ward.
Monitoring showed that this nurse came out soon after entering the dispensing room.
Because the nurse wears glasses, a mask on her face, and a hat on her head, no abnormalities can be seen from the surveillance.
This nurse pushed a car out of the dispensing room, and she went straight into the ward where Yang Yunzhong lived.
There were bodyguards guarding the door of the ward where Yang Yunzhong lived, but they did not interrogate the nurse.
After the nurse entered, she would come out in about a minute.
When she came out, she also said a few words to the bodyguard guarding the door.
What to say, the monitoring system without audio capture can't tell.
After pushing the dressing cart to leave, the nurse walked to the ward on the other side and disappeared from the surveillance range of this surveillance, but soon appeared in another surveillance.
After she walked to the ward closest to the elevator, she looked back at the direction of the monitoring, then put the dressing cart at the door of the ward, and people walked towards the elevator. After the elevator door opened, she walked in.
The police continued to track the surveillance inside the elevator and found that the nurse never showed up after walking to the washing room in another ward.
Police officers immediately went to the washing room and found that there was a set of changed nurse uniforms in the washing room, but no one was in it.
After inspecting the washing room, the police found that the toilet was next to the washing room.
After discovering the situation, they continued to check the surveillance and found that several men and women had entered and exited the bathroom during the period after the nurse disappeared.
After watching the surveillance footage back and forth, the police finally discovered that the number of people entering and leaving the bathroom was different. There were one more people who left the bathroom than those who entered the bathroom.
In other words, the "nurse" left from the bathroom.
After making strict comparisons, the police locked down a woman wearing a pink down jacket, a woolen cap and a mask on her face.
After the woman left the bathroom, she took the elevator downstairs again.
But what is depressing is that the elevator monitoring is actually broken and no monitoring video is left.
After checking all the surveillance videos in the hospital, the police still failed to find the woman's trace again.
All surveillance videos of nearby blocks were also called. The police used a large number of personnel to investigate all surveillance videos in the nearby area, but they still could not find clues. In other words, the woman just disappeared out of thin air.
The situation is also very clear. This is a man-made murder. An outsider dressed as a nurse injected a large dose of potassium chloride into Yang Yunzhong, causing Yang Yunzhong to suffer a cardiac arrest and death.
During the rescue, the medical staff also performed electrolyte and other biochemical tests on Yang Yunzhong.
The blood potassium concentration is as high as 18.7mmol/l, which is several times the upper limit of normal of 5.5mmol/l.
There are also many abnormalities that occur simultaneously with hyperkalemia.
Originally, the biochemical indicators in Yang Yun were basically normal, but the following abnormalities should be the result of hyperkalemia.
The large number of potassium chloride injections caused Yang Yunzhong's death. The police also recognized this. However, the medical and police personnel were puzzled by why Yang Yunzhong didn't respond when he was injected with potassium chloride.
You know, when a high concentration of potassium ions are injected into a blood vessel, the pain cannot be tolerated at all.
The patient must be struggling and calling behavior, but Yang Yunzhong did not show such behavior at all, and was always calm. UU Reading www.uukanshu.com
This is not very scientific.
The police also took his blood and sent it to the Criminal Identification Center to test whether there were any abnormal components in the blood.
After the patient died, the red blood cells in the body began to destroy.
The potassium in the red blood cells is released to the outside of the body after the cell is destroyed, that is to say, after the patient's death, the blood potassium concentration in the patient's body quickly rises. The potassium concentration in red blood cells is thirty to forty times that in plasma. The blood potassium concentration measured after Yang Yunzhong lost his vital signs has lost its meaning.
However, the police detected an anesthetic component in the patient's body. The existence of this ultra-short-term barbiturate drug explained everyone's doubts.
The woman dressed as a nurse injected Yang Yunzhong with a potassium chloride solution mixed with a highly effective anesthetic called thiopental sodium, or injected him with an anesthetic first and then potassium chloride. In this case, Yang Yunzhong was very Fast forward and fell into anesthesia without any response.
