Chapter 763: Fighting the God of Death for a Person

"Didn't take any medicine?" Xu Qiu confirmed again.

The man was about to nod, but suddenly remembered that his wife was still having diarrhea, so he immediately said, "Does medicine for stomachache count?"

"What."

"It seems to be called oxytetracycline."

Xu Qiu paused.

Oxytetracycline is an old antibiotic that was once popular in rural areas and was regarded as a miracle drug for diarrhea in the eyes of the older generation.

But now, because of the many side effects of the drug and most of them have developed drug resistance, it is no longer a routine choice for human medication, but has become popular in the field of veterinary medicine, such as the treatment of enteritis, gill rot, and vertical scale disease in fish.

However, oxytetracycline is very effective for diarrhea caused by intestinal infection or dysentery, and is still used by some old doctors in village clinics.

"Oxytetracycline can cause side effects, but they are concentrated in gastrointestinal reactions, liver and kidney damage, etc., which does not match Jiang Qiang's performance." Xu Qiu ruled out oxytetracycline.

After asking a few more questions, Xu Qiu did not get any valuable medical history, so he returned to the emergency room.

At this time, tracheal intubation had been completed here.

Oxygen mask doesn't work, but tracheal intubation will work, right?

However, to everyone's surprise, Jiang Qiang's oxygen saturation remained at an extremely low level.

Xu Qiu's face changed.

"Needle."

After a brief instruction, the nurse immediately prepared the equipment and completed the disinfection of the injection area.

Xu Qiu quickly inserted a needle, slowly increasing the strength in his hand. After a while, the dark brown blood slowly filled the needle.

"This..."

"How can it be this color!"

The doctors present were dumbfounded.

Rather than saying this is blood, it is more like melted chocolate syrup.

The moment he saw the chocolate-colored blood, a disease popped up in Xu Qiu's mind.

Methemoglobinemia.

It also has another nickname, called blue baby disease.

As the name suggests, people with this disease often have too much methemoglobin in their blood. The deep pathogenic mechanism is that the body cannot produce enough methemoglobin reductase and cannot reduce methemoglobin to hemoglobin.

Hemoglobin is the oxygen-carrying protein in the human body, which is reduced from methemoglobin. If it gets stuck at this step, the blood will naturally lose the ability to carry oxygen, which will lead to hypoxia and blueness...

The most classic manifestation is dyspnea, bluish skin, and cyanosis of mucous membranes.

Jiang Qiang's condition just fits the symptoms of methemoglobinemia.

"Prepare methylene blue." Xu Qiu ordered immediately.

The most effective rescue method for methemoglobinemia is oxygen inhalation.

Secondly, a large amount of infusion is used to dilute the concentration of toxins in the body. The drugs used are vitamin C and methylene blue. They are both reducing agents that can reduce trivalent methemoglobin to divalent ferrous iron, restore oxygen-carrying capacity, and significantly improve hypoxia symptoms.

Soon, 100 mg of methylene blue was injected into Jiang Qiang's body through intravenous injection.

Everyone was waiting.

Beep--

Beep--

Suddenly, the blood oxygen number on the monitor began to rise. In just a few minutes, it was maintained above 60, and as the methylene blue took effect, the patient's blood oxygen continued to rise to the normal range.

"Huh~"

Everyone's mood suddenly relaxed.

He was saved!

Many people wiped the sweat from their foreheads. In order to save this patient, most of them ran all the way, sent him to the emergency room and started treatment without stopping. Now they can finally take a breath.

This is the charm of the emergency department.

A life can easily pass away in your hands.

But at the same time, you will also get a chance to prolong your life because of the correct rescue drugs and reasonable treatment measures.

Fighting death is the true portrayal of emergency doctors.

...

The other doctors left with a relaxed look and returned to their posts.

Xu Qiu kept the family members.

Although the patient was saved and diagnosed with methemoglobinemia, there were still many points that Xu Qiu couldn't figure out.

For example, how could Jiang Qiang suddenly develop blue baby disease, and it was life-threatening right from the start!

There are many clinical reasons, such as genetics, allergic reactions, foods containing excessive nitrites, or toluene pigments, etc.

"Does her family have similar situations?" Xu Qiu asked.

Jiang Qiang's husband immediately shook his head and denied it: "Only her mother has a little high blood pressure, and everyone else is very healthy. By the way, her aunt's uncle died of liver cancer, does this count?"

Xu Qiu shook his head.

Family history only counts direct relatives, and liver cancer has no connection with Jiang Qiang's disease, so they can't be linked together.

After asking a few more questions, the possibility of hereditary methemoglobinemia was ruled out, so it could only be caused by acquired factors.

The most easily exposed foods in the family are nitrite foods, such as kimchi, pickled products, etc.

However, after asking, it was learned that Jiang Qiang's family did not have the habit of pickling kimchi, and they rarely ate these things.

The second one is mothballs that are easily exposed to clothing when storing clothes.

In the past, mothballs were made from naphthalene, which is not only a Class 2B carcinogen, but long-term exposure can also induce methemoglobinemia...

Although it has been banned, it can still be purchased in some places.

"There is no wardrobe where we live. All clothes are placed in a box. We have never used mothballs." Jiang Qiang's husband denied this guess again.

In this case... Xu Qiu fell into deep thought again.

Women often come into contact with nail polish remover.

But Xu Qiu did not see any traces of nail polish on Jiang Qiang.

Out of rigor, Xu Qiu still asked routinely, but as expected, he got a negative answer.

In fact, in addition to the above, there is another common substance, aniline, which is one of the chemicals that cause occupational diseases and has long been notorious, but the patient is a female worker in an electronics factory and cannot be exposed to these.

"Have you worked in other industries before?" Xu Qiu asked as usual.

The printing and dyeing industry, or work related to rubber, plastic, paint, perfume or drug synthesis, may be in close contact with aniline.

Jiang Qiang's husband shook his head: "We were assigned to the electronics factory for internship in our senior year, and then we stayed in this factory and never did anything else."

"I know."

Seeing that no more information could be collected, Xu Qiu could only return to the office.

The next morning, Jiang Mai, who was in charge of the handover, mentioned Jiang Qiang.

"This morning, the patient's arterial blood has turned red, and the patient has awakened and is in a good state of consciousness." Jiang Mai reported.

Wang Ping touched his chin... After listening to Jiang Mai's report, Jiang Qiang's condition was very clear. The question is, how did methemoglobinemia come about?
