Chapter 359: Changes in the Minus Sign

Soon, the results of the emergency blood test came out.

All the patient's test results were normal.

At this time, Wang Xiaodong also came to the emergency rescue ward.

"How is the patient?"

Lu Chen said: "After swallowing the battery, the patient had abdominal discomfort and ST segment elevation in the inferior wall lead of the electrocardiogram. Apart from that, the blood test results were normal, and there were no symptoms of chest tightness or chest pain."

"Please consult with the Department of Cardiology, General Surgery, and Gastroenterology." Wang Xiaodong said.

"I have already asked." Lu Chen replied.

"Okay." Wang Xiaodong nodded slightly. It's great to have Lu Chen in the team, which can save a lot of things.

In another week, Lu Chen will rotate to another department. At that time, he will really be uncomfortable!

"Lu Chen, what do you think of this electrocardiogram?" Wang Xiaodong looked at Lu Chen.

Since Lu Chen's reputation spread, whenever the department has an electrocardiogram that they don't know how to read, everyone will come to him.

"The inferior wall lead is indeed elevated, but the reason for the elevation is not yet known." Lu Chen said in a deep voice, "At present, myocardial infarction can be ruled out. I think it may be due to the battery."

"You said it was caused by the battery?" Wang Xiaodong asked doubtfully.

"Well, that's the only way to think about it now." Lu Chen said.

At this time, the patient's life value suddenly dropped again!

It became 64 (--).

"Doctor, my stomach is still very uncomfortable!" The patient was lying on the bed, holding his stomach.

"Use some stomach-protecting medicine first." When encountering such a patient who swallowed a battery, Wang Xiaodong did not dare to use other medicine rashly.

At this time, Cheng Peng said, "Brother Wang, the patient's chest X-ray image is out."

Everyone immediately came to the computer to check the image.

The chest X-ray showed that there was a radiopaque metal body in the patient's gastric antrum.

This should be the battery he swallowed.

"It seems that he really swallowed a battery." Wang Xiaodong frowned and said, "Let's wait for the consultation opinions of the relevant departments first."

About five minutes later, the cardiologist came.

However, this was the first time that everyone encountered a patient who swallowed a battery, and there was no particularly good way to deal with it.

"Don't consider myocardial infarction for now." The opinion of the cardiologist was very clear.

Based on the patient's symptoms and blood test results, the diagnosis of myocardial infarction is definitely not valid!

Lu Chen stood in front of the computer and carefully compared the patient's chest X-ray.

"If the battery affects the changes in the electrocardiogram, then there is only one possibility!" Lu Chen thought to himself.

Batteries are foreign objects after all.

When foreign objects enter the human body, the first thing to consider is whether there is a possibility of airway obstruction.

Judging from the patient's symptoms, there is definitely no such possibility.

Secondly, whether the foreign object is toxic and how toxic it is!

Substances such as pesticides, rat poison, and metals can cause damage to the human body.

The situation where batteries enter the human body is relatively rare, and most doctors don't really understand it.

However, Lu Chen had previously obtained a skill card for emergency toxicology, and he also studied it after returning.

The hazard of batteries is that their surface comes into contact with the conductive tissue of the esophagus, causing severe burns.

This contact will generate an electric current and decompose nearby water into highly corrosive liquid.

Looking at the chest X-ray in front of him and thinking of the location of the battery, Lu Chen suddenly had an epiphany.

"Brother Lu, did you find anything?" Wang Xiaodong asked as he watched Lu Chen staring at the chest X-ray.

Lu Chen nodded slightly: "Brother, I think I understand why the patient's electrocardiogram is like a heart attack."

Wang Xiaodong and Cheng Peng came up immediately after hearing this.

Lu Chen paused for a moment and said: "Since gastric acid has a corrosive effect on batteries, and the contents of batteries are strong acids and strong alkalis, once the battery surface is corroded and the contents leak, it will corrode the digestive tract. It just so happens that the stomach is facing the lower wall of the heart, which may lead to ST segment elevation!"

"In fact, the ECG waveform feels weird. Not only is the lower wall elevated, but the chest leads are also elevated!" "

"This graph also needs to rule out the possibility of interference! According to the Einthoven triangle, the I lead waveform is quite good. It is indeed necessary to rule out the waveform changes caused by interference from the left lower limb! ”

“…”

Lu Chen’s explanation was very simple. It was the corrosion of the battery by gastric acid. Its position was right against the lower wall of the heart, so it caused the change in the electrocardiogram.

Cheng Peng on the side suddenly realized: "Lu Chen, after listening to you, I understand. It seems that the electrocardiogram is not only about the heart. As long as we know the principle of the generation of the electrocardiogram, we can better understand these things. ”

“Yes, that’s right. "Lu Chen smiled.

Wang Xiaodong nodded slightly.

Lu Chen's explanation seemed simple, with only a few words, but being able to explain the electrocardiogram from this level is not something that ordinary people can do!

No wonder Lu Chen was able to get the sixth place in the electrocardiogram competition, this is all due to his ability!

After initially understanding the patient's condition, the next step is treatment.

The battery must be taken out!

But the method of taking it out is to use a gastroscope or a surgical method, which depends on the judgment of general surgery and gastroenterology.

As for the method of excretion, it is still unclear whether it can be excreted. Once the battery stays in the gastrointestinal tract for too long, it may cause corrosion to multiple parts of the intestine.

That would be more harm than good!

Therefore, vomiting and excretion methods are not advisable.

"Doctor... I won't open my abdomen, right?" The patient lay on the bed with a bitter face.

Accidentally swallowing a button battery actually caused so much trouble.

"Not necessarily." Lu Chen said, "Looking at the position of this chest X-ray, it may be possible to take it out with a gastroscope, but the specific method still needs to be determined by other professional departments."

Lu Chen did not say anything definite.

Gastroscopy is just a minimally invasive surgery, but laparotomy is a major surgery.

"Doctor, if you can use a gastroscope, use a gastroscope." The patient pulled Lu Chen's sleeve and cried, "I'm still young, I really don't want to do this kind of surgery!"

"This is determined by your condition. If the gastroscope cannot be taken out, surgical methods must be used." Lu Chen said seriously, "Once the battery stays in your body for a long time, the damage may become greater and greater. At that time, it will not only change the electrocardiogram!"

Although the patient looks stable now, the two "--" after the life value number on his head forced Lu Chen to carefully explain his condition.

If this battery is not taken out as soon as possible, it will sooner or later be a big problem!

After hearing Lu Chen's explanation, the patient could only sigh slightly and accept his fate.

About a few minutes later, the gastroenterology department and the general surgery department came.

After comprehensive consideration, they chose to remove the battery by gastroscopy.

However, if it fails, the endoscopic operation will be converted to a surgical operation!

…

Before approaching the gastroscopy room, UU reading www.uukanshu.net Lu Chen also used "honey" treatment on the patient.

This method is not in the textbook, but Lu Chen found it in a newly published document.

After swallowing the battery by mistake, the risk of tissue damage can be reduced by using honey multiple times.

Regardless of whether it is useful or not, after obtaining the patient's consent, Lu Chen used honey on the patient.

About ten minutes later.

Lu Chen saw that the minus sign after the patient's life value number changed from "--" to "-"!

Sure enough, honey is effective for the early treatment of such patients!

At this time, a prompt popped up on the system panel.

"Congratulations, the system upgrade completion rate has reached 1%!"
