Meth is commonly known as amphetamine or methamphetamine. This substance derived from ephedrine hydrochloride is also called "amphetamine" together with Ritalin and dextroamphetamine.

Unlike ordinary opioid sedatives, amphetamine is a central nervous system stimulant with strong potency. It can stimulate neurons in the human brain's blue spots, striatum and other parts. This leads to unconscious increase in movement, hyperactivity, stereotypes, irritability and other behaviors, mental changes, and even self-harm.

This central stimulant was widely used in the military field during World War II. A large number of soldiers became excited but not afraid of death after taking amphetamines, and did not need rest, and even logistics was not needed - after taking amphetamines, the effect of the drug would suppress appetite.

During World War II, besides the United States, only Germany and the inventor of amphetamine were left. Since the Japanese chemist Atsuto Kado first used ephedrine to synthesize methamphetamine in 1920, Japan's technology to extract amphetamine with ephedrine has made rapid progress. The concentration of the extracted finished product can almost reach 100%. The Japanese expatriates who mastered this technology and immigrated to Hawaii discovered a large demand for methamphetamine in the United States. Especially after the United States further strengthened its control of methamphetamine 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 methods of manufacturing methamphetamine were also substituted into central America and Mexico. Due to the relatively relaxed attitude towards drugs in the Western world, more serious drug abuse problems have been triggered.

This is why there were similar cases of Gao Yan in Hawaii Week. Among the acute poisoning caused by methamphetamine (abbreviated as MA), there are 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 tranquilizers generally develop resistance to anesthesia - they cannot effectively anesthetize and relieve pain at low doses, and at high doses, they are more likely to have adverse reactions than ordinary people.

However, in the Fourth Central Hospital, there was no means to detect whether the urine contained methamphetamine metabolites. Although the Provincial Occupational Disease Prevention and Control Hospital had such technology, the test results were too slow. Only then did Sun Lien call the police station to pay attention.

Unlike the Western world, China can be said to be the country with the most harsh attitude towards drugs. Grassroots police stations are basically equipped with test tools to combat drug use - quick test strips.

The quick test strip can test whether the person being tested has used drugs in the past two weeks, and can pass the hair for more than two weeks. Judging from Gao Yan's onset, he should have taken drugs about a week ago. It just so happens that he is still within the range of the quick test strip.

"Test strip?" Old Wu put down the rag in his hand and said with a warning look on his face, "Yes, yes, what do you want this?"

"I suspect the knife wound I sent today may have been a methamphetamine." Reporting the drug addict to the police was also one of the doctor's work content. Sun Lien had no other thoughts on how to punish Gao Yan for drug addicts. He just wanted to diagnose the condition and save his life - he was just 21 years old, and his life should have many possibilities. It was a pity to die in the hospital bed in the emergency room of the hospital.

"Method?" Old Wu nodded thoughtfully, "You wait a moment, I'll look for it."

The police room at the entrance of the Fourth Central Hospital is not large, just about 20 square meters. In addition to office supplies, there are mainly several sets of steel forks, transparent shields and helmets used to control people. The police room, which was not very large, suddenly became a little cramped. Old Wu bent over and looked around in the police room, and finally took out a small cardboard box from the drawer. However, he did not hand the reagent to Sun Lien, but put it in his pocket. "Let's go, I'll go with you."

A law enforcement recorder was hung next to Lao Wu's shoulder, following Sun Lien and swayed all the way to the ICU. Considering that law enforcement might be obstructed, Lao Wu did not greet Gao Yan's parents who were waiting outside the door, but walked into the ICU first. He asked the young nurse on duty to come with an unused paper cup. Lao Wu squatted down skillfully and released a little grass-green urine from Gao Yan's urine bag. Then he used the test paper to do the experiment.

Five minutes later, an obvious horizontal bar appeared on C on the test strip. It was confirmed that it was a positive reaction. Lao Wu used a law enforcement recorder to retake the reaction and said to Sun Lien, "What should I do? Can the patient's condition stabilize?"

Sun Lien ignored the rolling eyes of the ICU nurse and was quickly notifying Xu Yourong on WeChat on his mobile phone. While sending WeChat, he shook his head and said, "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."

As expected, Gao Yan's parents fiercely denied the fact that their son had used methamphetamine. The old couple looked at Sun Lien with shock and resentment. I guess if it weren't for the fact that Old Wu was wearing a police uniform, they would have come up and beat Sun Lien up on the spot to relieve their resentment.

However, the prompts for quick tests do exist, and the symptoms of high severity do meet the characteristics of acute methamphetamine poisoning. Although the quick test may be false positive, after comprehensive consideration, the most appropriate method is now used to treat acute poisoning.

"Adjust the treatment plan." Sun Lien has not treated acute methamphetamine poisoning, but Xu Yourong saw more OD (overdose, overdose) patients during his internship in the United States may be more than Sun Lien's emergency patients. She skillfully adjusted Gao Yan's treatment content, "Two grams of vitamin C, 200 ml of glucose. Inject it once every 12 hours. Increase the total amount of rehydration and inject it according to the standard of 8 liters per day." Xu Yourong's plan was rough and direct, "Inject 200 ml of mannitol every two hours. He called his kidneys to work."
