Chapter 168 Professor Lu, You Are Amazing!

Both propafenone and atenolol are antiarrhythmic drugs.

But one thing is very interesting, all antiarrhythmic drugs can cause arrhythmia!

Therefore, clinically, the use of any arrhythmia drug is very cautious.

For example, general premature beats, whether premature ventricular or atrial premature beats, as long as there is no organic heart disease, no special treatment is required, and no antiarrhythmic drugs are required.

Substance abuse can lead to more serious consequences!

……

Lu Chen's clinical career was very short, and he never encountered propafenone poisoning.

The drug principle of propafenone in the treatment of arrhythmia is to increase the refractory period of cardiomyocytes, thereby blocking the depolarization of ectopic cells and allowing sinus rhythm to preemptively occupy.

However, during his internship, Lu Chen encountered a patient with aconitine poisoning.

Aconitine, like propafenone, can inhibit sinus node function.

At that time, the patient had frequent premature ventricular and short bursts of ventricular tachycardia, and did not receive blood purification treatment, but only used drug treatment, and finally his condition improved.

After thinking about it, Lu Chen immediately edited and replied.

"Director Fan, if you can stabilize sinus rhythm and blood pressure, hemoperfusion may have a certain effect."

Fan Zhiping kept staring at the dialogue with Lu Chen.

When Lu Chen's news appeared in the dialog box, he looked happy.

This is what he saw today, the first person to say that hemoperfusion is effective.

Fan Zhiping immediately replied: "But the patient's blood pressure is not stable, fluctuating at 90/50mmHg all the time, and the electrocardiogram now shows that it is rapid atrial fibrillation, with a heart rate of 130 beats."

"That might not work. We have to solve the problem of arrhythmia first." Lu Chen frowned.

"Can you do cardioversion?" Fan Zhiping sent another message.

Generally, patients with arrhythmia with unstable hemodynamics, that is, low blood pressure, can basically use electrical cardioversion.

"This patient cannot use electrical cardioversion." Lu Chen replied, "The patient's sinus node function is inhibited, and there is a potential conduction block, which is a contraindication for electrical cardioversion."

The electrical conduction system of the heart is a system with distinct upper and lower levels.

The sinoatrial node sends out electrical impulses, which are then conducted down through the steps.

The sinoatrial node is equivalent to a commander, controlling all the conduction systems downstream.

Once the function of the sinoatrial node is inhibited, without the Commander, the electrical conduction system of the heart will be in chaos.

"Then what else can we do?" Fan Zhiping asked doubtfully.

"Push half a dose of atropine first!"

When the message sent by Lu Chen appeared on Fan Zhiping's phone screen, he was stunned.

The blue light from the screen accentuated the astonishment on his face even more.

However, the movement in his hand was not slow, and he immediately replied: "Are you sure?"

"Sure!"

To be on the safe side, Lu Chen asked Fan Zhiping to push half atropine.

Seeing Lu Chen's exact answer, Fan Zhiping did not hesitate.

He immediately placed a doctor's order in the computerized medical record system—an intravenous injection of half atropine.

"Luo Xin, give half a dose of atropine to the poisoned patient who came here just now! I have given the doctor's order." Fan Zhiping walked out of the doctor's office and came to the nurse's station.

"Got it!" After Luo Xin agreed, she felt that something was wrong, "Director Fan, the patient's heart rate is 130 beats per minute. Are you sure you need to give half a dose of atropine?"

Atropine is a drug that raises the heart rate!

In many medical dramas, an emergency case is involved, which is organophosphate poisoning.

The specific antidote for organophosphate poisoning is atropine.

At this time, a large amount of atropine needs to be injected intravenously, so there will be various scenarios of concerted efforts to "break atropine by hand".

But now, their patient's heart rate is 130 beats per minute.

Also give him atropine?
Will the heart rate continue to soar?

Based on his shallow knowledge, Luo Xin felt that this should be a wrong doctor's order.

"That's right, it's an intravenous injection of half atropine, push it now!" Fan Zhiping's voice was unquestionable.

Seeing this, Luo Xin could only follow the doctor's orders.

She came to the ward and took out the medicine on the emergency cart.

Slowly injected half a tube of atropine intravenously to the girl on the hospital bed.

Both Fan Zhiping and Luo Xin stood by the hospital bed, staring closely at the ECG monitor next to the bed.

Atropine works very quickly.

Just finished pushing, less than half a minute.

The patient's heart rhythm changes.

On the bedside ECG monitor.

Patient's heart rhythm changed from atrial fibrillation to sinus rhythm (normal heart rhythm)!
Heart rate dropped from 130 beats/min to 80 beats/min.

Luo Xin's eyes widened, watching the patient's heart rhythm changes with his own eyes, this scene was still very shocking.

She stared at the EKG monitor, terrified that it was just a flash in the pan.

It lasted about 1 minutes.

The patient's heart rate stabilized, basically maintaining 80 beats per minute.

Fan Zhiping immediately leaned forward and asked the patient on the bed.

"Student, do you feel flustered better?"

On the hospital bed, the girl nodded slightly: "After the injection just now, I feel more comfortable."

Fan Zhiping was also astonished.

Half of atropine actually solved the problem of arrhythmia!
Until now, he hadn't figured out the reason for this.

Atropine is obviously a drug that raises the heart rate!

Why did the patient's heart rate drop after using it?

"Luo Xin, take care of the patient first, and call me whenever there is a situation."

"it is good!"

Fan Zhiping immediately walked out of the ward and came to the corridor.

Taking out his phone, he immediately edited a message to Lu Chen in a very excited mood.

"Professor Lu, you are amazing!"

If it was said that Fan Zhiping could not save face before, but now, he yelled out the words "Professor Lu" without any psychological burden.

It doesn't matter how old he is, whether he is a student or something else.

At this moment, Lu Chen is like a "professor" to Fan Zhiping!
When Lu Chen received this message, a smile appeared on his face.

It seems that the patient's arrhythmia problem has been solved!
Lu Chen continued: "Change to a small dose of atropine micropump, maintain a sinus heart rate of about 80 beats per minute, and last for five half-lives of propafenone, about 1 and a half days. Let's deal with other situations!"

"Received!" Fan Zhiping replied immediately.

Lu Chen's words are now the "imperial decree"!
"Luo Xin, use a small dose of atropine micropump to keep the patient's heart rate at 80 beats per minute!" Fan Zhiping shouted to Luo Xin in the ward with his mobile phone.

"Okay, Director."

Luo Xin also saw how powerful Director Fan is, so he didn't have any doubts about it.

She immediately carried out Fan Zhiping's doctor's order.

"If there's nothing else, I'll be busy first." Lu Chen said.

"Professor Lu, go get busy, I won't bother you."

The current Fan Zhiping calls out the three words "Professor Lu", without any embarrassment, on the contrary, he finds it very easy to pronounce!
