Chapter 101 Acute methamphetamine poisoning
Meth is the common name for amphetamine or methamphetamine.This substance derived from ephedrine hydrochloride is also called "amphetamine" together with Ritalin and dextroamphetamine.

Unlike ordinary opioid tranquilizers, amphetamine is a potent central nervous system stimulant.It can stimulate neurons in the locus coeruleus, striatum and other parts of the human brain.As a result, the human body will experience involuntary increased exercise, hyperactivity, stereotyped exercise, irritability and other behavioral and mental changes, and even self-harm may occur.

This central stimulant was widely used in the military field during World War II.After taking amphetamines, a large number of soldiers became hyperactive without fear of death, did not need to rest, and even did not need much logistics—after taking amphetamines, the drug effect would suppress their appetite.

During World War II, apart from the United States, only Germany and Japan, the country where amphetamine was invented, were widely used as a military stimulant.Since the Japanese chemist Axiong Kata first synthesized methamphetamine using ephedrine in 1920, Japan's technology of extracting amphetamine from ephedrine has advanced by leaps and bounds.The concentration of the refined product can reach almost 100%.The Japanese expats who mastered this technology and immigrated to Hawaii discovered a large demand for methamphetamine in the United States.Especially after the control of methamphetamine was further strengthened in the United States in the mid-1980s, a large number of underground homemade methamphetamine began to appear.

These products flowed into the United States under the control of local gangs.At the same time, the method of manufacturing methamphetamine was also substituted into the central United States and Mexico.Due to the relatively relaxed attitude towards drugs in the Western world, a more serious problem of drug abuse has been triggered.

This is why there have been similar reported cases in Hawaii Zhou and Gao Yan.In acute poisoning caused by methamphetamine (abbreviated as MA), there will be very few cases of high fever, extremely high creatine kinase, high cerebrospinal fluid pressure, and grass-green urine.At the same time, people who abuse stimulants or sedatives generally develop resistance to anesthesia-they cannot effectively anesthetize and relieve pain when the dose is low, and are more prone to adverse reactions than ordinary people when the dose is high.

It's just that in the Fourth Central Hospital, there is no way to test whether the urine contains methamphetamine metabolites.Although the Provincial Occupational Disease Prevention and Control Hospital has such technology, the test results come out too slowly.Only then did Sun Lien call his attention to the police station.

Unlike the Western world, China is arguably the country with the strictest attitude towards drugs.Grass-roots police stations are basically equipped with quick-test test strips, an artifact to combat drug abuse.

Quick test strips can test whether the person under test has used drugs in the past two weeks, and hair can be used for more than two weeks.Judging from Gao Yan's onset, he should have taken drugs about a week ago.It happened to be within the detection range of the quick test paper.

"Test paper?" Old Wu put down the rag in his hand, and said with a vigilant expression, "Yes, there is, why do you want this?"

"The knife wound sent today, I suspect that it may have been drugged." It is also part of the doctor's job to report the situation of the drug addicts found to the police.Sun Lien had no other ideas on how to punish Gao Yan for his drug use. He just wanted to diagnose his illness quickly and save his life—he was just 21 years old, so there should be many possibilities for his life.It is such a pity to die on the bed in the emergency room of the hospital.

"Ice?" Old Wu nodded thoughtfully, "Wait a minute, I'll look for it."

The police room at the entrance of the Fourth Central Hospital is not big, about [-] square meters in size.In addition to office supplies, there are mainly several sets of steel forks, transparent shields and helmets for controlling people.The police room, which was originally not very big, suddenly seemed a little cramped.Old Wu bent down and searched around in the police room, and finally took out a small cardboard box from the drawer.But he didn't give the reagent to Sun Lien, but put it in his pocket. "Let's go, I'll go with you."

Lao Wu hung a body camera on his shoulder, followed Sun Lien, and swayed all the way to the ICU.Considering that law enforcement might be obstructed, Lao Wu didn't greet Gao Yan's parents who were waiting outside the door, but walked into the ICU first.Asking the little nurse on duty for an unused paper cup, Lao Wu skillfully squatted down and released a bit of grass-green urine from Gao Yan's urine bag.Then experimented with test paper.

After 5 minutes, an obvious horizontal line appeared on track C on the test paper.Confirmed to be a positive reaction.After Lao Wu focused on his reaction with the law enforcement recorder, he said to Sun Lien, "What should I do? Can the patient's condition be stabilized?"

Sun Lien ignored the white eyes of the little nurse in the ICU, and was quickly notifying Xu Yourong via WeChat on his mobile phone.He shook his head while sending a WeChat message, "It's hard to say, he has been poisoned for a long time. Let's go to the treatment first, let's take a look at it."

As expected, Gao Yan's parents vehemently denied the fact that their son had used meth.The eyes of the old couple looking at Sun Lien were full of shock and resentment. If it weren't for the presence of Old Wu in police uniform, they would have come up on the spot to beat up Sun Lien to relieve their grievances.

But the hints from the quick test did exist, and Gao Yan's symptoms did meet the characteristics of acute methamphetamine poisoning.Although there is a possibility of false positives in the quick test, after comprehensive consideration, it is the most appropriate method to treat according to acute poisoning.

"Adjust the treatment plan." Sun Lien has never dealt with acute methamphetamine poisoning, but Xu Yourong may have seen more OD (overdose, overdose) patients during his internship in the United States than Sun Lien had seen emergency patients.She skillfully adjusted Gao Yan's treatment content, "Two grams of vitamin C, mixed with 200 milliliters of glucose. Infuse once every 12 hours. Increase the total amount of rehydration fluid and inject it according to the standard of 8 liters per day." Xu Yourong's plan was brutal and direct, "200ml of mannitol intravenously every two hours. Woke his kidneys to work."

No matter what kind of poisoning it is, getting the toxin out of the body as soon as possible is the first means of treatment.Vomiting when people eat spoiled food is a natural evolutionary means of eliminating toxins.And now there is obviously no point in making Gao Yan get up from the bed to vomit - methamphetamine is not taken orally, and too much time has passed.What the doctors can do now is to speed up the metabolism in Gao Yan's body.Let the kidneys work hard, hoping to expel as many toxic substances from his body as possible.

　Thanks to the lord Xinyun Qianyin for the reward... Unfortunately, I have been a little more immobile these days.The lord Jiageng is temporarily owed, a total of five shifts... Make it up as soon as possible.

　　If there are other book lovers who want to reward the leader... think twice!
