"The recent mortality rate of heart disease patients in this hospital is very high, and there may be a lot of unexplained and unexplained things in it." Jiang Chonglang and several people quickly rushed to the hospital, visited the patients in the hospital, and looked through the death records of the most recent heart patients in the hospital.

Sure enough, after investigation, it was found that in recent months, the number of deaths of patients in the hospital's cardiology department has surged, and most of these patients are treated by an old doctor named Zhang Baiyue.

Just two days ago, another heart patient had just passed away, as the family had doubts about the cause of his death. So don't agree with the spark. Therefore, the body is still in the morgue. Jiang Chonglang hurriedly sent someone to take the body away for examination, and controlled Zhang Baiyue.

After a detailed autopsy examination of the corpse, it was found that the deceased had been injected with an excessive amount of muscle relaxant chlorzoxazone for a long time before his death, as the family of the deceased testified, the deceased was often dizzy, drowsy and had excessive potassium concentration in the blood a few days before his death.

Chlorzoxazone is a common muscle relaxant. Also known as chloroxybenzoxazole; 5-chloro-2-hydroxybenzoxazole; chlorbenoxazolone; chloroxybenoxazole; Chloroxybenzoxazole, etc.

Chlorzoxazone mainly acts on the central nervous system, inhibiting the polysynthetic arc in the spine and the inferior cerebral cortical area, thereby producing a muscle relaxant effect on spastic skeletal muscles and achieving analgesic effects. It is used for various acute and chronic soft tissue (muscles, ligaments, fascia) sprains, contusions, pain caused by muscle strain after exercise, muscle spasms caused by central nervous disease, chronic fasciitis, etc.

However, if the human body is injected with too much chlorzoxazone, it will cause the respiratory tract muscles to relax and make it difficult to breathe, and in severe cases, it will suffocate to death. A female doctor in Brazil, Virginia Sols de Souza, died by injecting patients in the intensive care unit with a lethal overdose of chlorzoxazone while reducing the oxygen supply to the patients.

After investigation, the deaths of at least 20 patients were linked to De Suza. In addition, I am afraid that the deaths of more than 300 patients are inseparable from Virginia. And her motive for committing the crime: just to free up the hospital bed.

At the same time, if the concentration of potassium ions in the blood is too high, it can lead to irregular heartbeat and rapid heartbeat.

KCl is a colorless, elongated diamond-shaped or cubic crystal, or white crystalline powder with small particles, which looks like table salt sodium chloride.

KCl is odorless and salty. Therefore, KCl is often used as an additive for low-sodium salts and mineral waters. KCl is a commonly used electrolyte balance regulator in clinical practice, with definite clinical efficacy, and is widely used in clinical departments of hospitals.

However, KCl has certain toxicity: the half-lethal dose of oral administration is about 2500mg/kg; The half-lethal dose of intravenous injection is about 100 mg/kg, and it has serious side effects on the myocardium: high doses of injections can lead to cardiac arrest and even sudden death of the injected person. The principle of lethal injection is based on this principle.

After interrogation, Zhang Baiyue quickly admitted his crime, and he had used this method to kill several heart patients in the hospital with Lian Xijiao. The reason why the two of them killed so many people so frantically was because Lian Xijiao was in a romantic relationship with Zhang Baiyue's son Zhang Yu, and Zhang Yu was admitted to the hospital for a heart attack a few months ago and was waiting for a heart transplant.

The hospital where the two of them work is the best hospital for treating heart diseases in the entire city of Yangcheng, so there are many patients who come here for treatment, and there are also many people waiting in line for heart transplants. Therefore, Changyu's surgery date could not be put on the agenda for a long time.

Moreover, Zhang Baiyue has doubts about the current heart transplant method in the hospital, believing that it is risky, and the patient will have obvious rejection reaction after thinking about transplantation, and the survival time is not long, so he does not dare to rashly give his son a heart transplant. Coincidentally, at this time, his future daughter-in-law Lian Xijiao proposed to Zhang Baiyue that she was engaged in heart transplantation research, and showed Zhang Baiyue her research progress, but her professional title was low and her qualifications were too shallow. I'm afraid the hospital won't agree with it. Lian Xijiao said that if her research results are proven to be feasible, once successful. Not only can Changyu survive, but also get a large amount of bonuses, which will also be of great help to his future career.

Regarding Lian Xijiao's current research results, Zhang Baiyue has both places for favor and places for existence, and thus places for opposition. But in the face of money and the lives of their loved ones, Zhang Baiyue and Lian Xijiao decided to take risks. Lian Xijiao discussed, found a few people's hearts to test her research results, she had a way to kill him and disguise it as suicide, so that others could not see the flaws. So, Lian Xijiao used sexual suffocation to kill Ren Mingtao, Gu Yongzhen, Xie Liang and Ma Lei one after another. The technique of acupuncture was also taught to Lian Xijiao by Zhang Baiyue, because he was afraid that some men were strong and strong, and Lian Xijiao would not be able to deal with them.

At the same time, Zhang Baiyue also hastened the death of some patients by giving them oral or excessive muscle relaxants, as well as intravenous injections of KCl solution instead of sodium chloride solution.

In the process of Zhang Baiyue's killing, the victims he chose were generally some older patients. Because this is not easy to be suspected by the patient's family, but it is still seen by some of the deceased's family members, and once again a patient's family doctor made trouble, and came to the door with a knife to cut Zhang Baiyue, but was stopped by Lian Xijiao, and also injured Zhang Lanshan who was present.

At the end of the interrogation, Zhang Baiyue also left tears of remorse. What Jiang Chonglang didn't dare to tell Zhang Baiyue was: Just a few hours ago, his son Zhang Yu learned that his father and girlfriend were arrested for murder at the same time, and his condition deteriorated rapidly because he couldn't stand the blow, and died after rescue efforts failed.

So far, the truth of this serial murder case has been completely revealed. Angels and demons, hell and heaven. In fact, just in the moment of people's thoughts, behind the snow-white mask, is it a wonderful hand and benevolence, or a knife mouth tofu heart. None of this matters, don't be a Buddha's mouth. Jiang Chonglang and Zhang Lanshan closed the file of this case and sighed heavily.

The case has finally been solved now, and the police officers of the serious crime team have finally breathed a sigh of relief, but everyone's Christmas holiday and New Year's Day holiday have been ruined because of this. So everyone clamored for compensation. Jiang Chonglang agreed: "Listen to everyone, go out for dinner in the evening." There should be a KTV in the private room for dinner, and we will drink and sing while eating. We have to get drunk before we rest, and if we don't get drunk, we won't return. ”
