He saw that tracheal intubation had been completed and bilateral lung ventilation had been ensured. The remaining task was to restore the patient's spontaneous heartbeat.

So Wu Xiangdong looked at Li Yanan standing aside: "Leave ventilation to Lao Wan for the time being. You can then give the patient an epinephrine and observe the changes in his vital signs."

"Okay." As the assistance ended, Li Yanan handed the simple respirator back to Wan Zhihua's hands, and she pushed the added epinephrine into the patient's body through a syringe.

With the release of a large amount of adrenaline, the blood vessels of the patient's heart, liver, and muscles begin to expand, and the blood vessels of the skin and mucous membranes further contract, allowing all energy to be concentrated into the heart.

Under the dual effects of the drug and Wu Xiangdong's compressions, the heart, which was originally weak in contraction, gradually began to respond after receiving stimulation.

"Doctor Wu, look at the waveform on the ECG monitor. It seems to be different from before." Li Yanan, who had been keeping a close eye on the patient's changes, suddenly noticed the change in the heart rhythm on the screen.

Following her reminder, Wu Xiangdong immediately stopped pressing and looked up at the monitor aside.

I saw that the heart rate, which was originally a straight line, gradually began to pulsate, and the wide and deformed U waves were like big waves, quickly filling up the entire screen of the monitor.

"This is a ventricular tachycardia wave, and the patient's rescue is effective!" Li Yanan's reminder made Wan Zhihua, who was ventilating the patient, couldn't help but turn his head and look at the monitor placed aside.

After seeing the U-shaped wave, Wan Zhihua became a little excited. As long as he worked hard, he might be able to save the patient in front of him.

At this time, Wu Xiangdong seemed very calm. Since the patient had partially recovered his heart rate, he no longer needed to perform chest compressions.

Wu Xiangdong rubbed his somewhat red wrist and said to Li Yanan who was standing aside: "Yanan, there should be amiodarone in the rescue vehicle. Just give him two doses and see the effect."

"Two?" Li Yanan was slightly frightened after hearing this. She knew about the drug amiodarone. She used to use this kind of drug frequently when she was still in the cardiology department.

Amiodarone, a third class of antiarrhythmic drugs, is a mildly noncompetitive alpha and beta adrenergic receptor blocker.

It has a direct dilation effect on coronary arteries and peripheral blood vessels, and can effectively eliminate the damage caused to myocardium by malignant arrhythmias such as ventricular tachycardia.

However, there are clinical requirements for the dosage of amiodarone. Like the two intravenous amiodarone injections Wu Xiangdong said, she had never tried it before, so she was a little hesitant when facing his instructions.

When Wu Xiangdong saw this, he showed a very confident look: "It is said that in troubled times, heavy prescriptions are used, and for serious illnesses, strong medicines are used. The dose of 300 mg is not much for him now, so you can rest assured and use it."

"Okay, I listen to you." Li Yanan nodded. Her trust in Wu Xiangdong was unconditional, so she directly found two amiodarones from the drawer of the rescue vehicle, broke them open and drew out a ten milliliter syringe.

inside.

"300mg amiodarone intravenous injection." Li Yanan repeated the doctor's instructions again, and after Wu Xiangdong nodded to confirm, he pushed all the medicine into the patient's body.

"Okay, leave the rest to me." Wu Xiangdong took advantage of the effect of amiodarone to start to work in the patient's body. He directly pushed the defibrillator placed aside to the patient's side and adjusted the parameters on it.

.

Slightly different from the previous asynchronous electric defibrillation, Wu Xiangdong manually turned the button to synchronized electric cardioversion this time. This was done according to the patient's indications.

Generally, asynchronous electrical defibrillation is suitable for the treatment of ventricular flutter and ventricular fibrillation. It is a means of rescuing malignant arrhythmias and is one of the key technologies for successful rescue of cardiac arrest patients. Synchronous electrical defibrillation is used for cardioversion.

Various types of ectopic tachyarrhythmias other than ventricular fibrillation.

Wu Xiangdong looked at the ventricular arrhythmia on the screen, which was well over 200 beats/min. After confirming again that it was correct, he pressed the electrode pads of the defibrillator against the patient's body.

"Synchronized electrocardioversion 100J is ready. Everyone leaves and leaves alone." Wu Xiangdong pressed the charging button and glanced around with the corner of his eyes. At this time, Wan Zhihua and Li Yanan took a step back at the same time and left the rescue in a tacit understanding.

bed.

Therefore, Wu Xiangdong hunched over, ensuring zero contact with the patient's whole body, and then held the electrode pads with both hands and pressed hard toward the patient's heart area.

At the same time, press the discharge button with your thumb, and the current is concentrated on the electrode plate again, and is conducted to various areas of the heart through the sternum.

The originally unresponsive heart gradually began to beat under the dual effects of the drug and the electric shock.

"Sinus, the patient has returned to sinus rhythm." At this time, Li Yanan cried out excitedly after seeing the waveform on the monitor.

"The QRS wave complex is normal, and there is no malignant arrhythmia for the time being." Wu Xiangdong also glanced at the monitor, then picked up the stethoscope on the side, starting from the mitral valve auscultation area on the patient's chest, and then followed the aortic valve, pulmonary valve, and

Check the tricuspid valve auscultation areas one by one.

At this time, the entire rescue room was silent except for the regular sound of squeezing the balloon. Everyone looked nervously at Wu Xiangdong who was undergoing the examination, not daring to disturb him at will.

"The systolic and diastolic functions of the heart are normal, and the patient has been rescued." Wu Xiangdong put down the stethoscope in his hand and glanced at the clock hanging on the wall. Eight minutes had happened to have passed from the beginning to the end of the rescue. This made him

I couldn't help but let out a long breath.

With Wu Xiangdong's judgment, the entire tense atmosphere instantly relaxed, and Li Yanan was even more excited and speechless.

"That's great." Wan Zhihua also breathed a sigh of relief at this time. You must know that once the rescue time exceeds ten minutes, the brain will be irreversibly damaged. In this way, all their efforts will be greatly compromised.

, or even go to waste.

"Help him organize his belongings. It won't be long before he wakes up." Wu Xiangdong said confidently.

"Okay." Li Yanan was also very excited at this time. She came to the patient, looked at the sleeves that had been pulled open due to the rescue, then put it on him again and zipped up his coat.

When she was further organizing the patient's belongings, she discovered that the originally unconscious patient actually blinked his eyelids.

"Hey, Doctor Wu, the patient seems to have woken up."

"Really?"

Following Li Yanan's reminder, Wu Xiangdong also came to the patient. He held the patient's hand, leaned down to the patient's ear, and asked: "Uncle, can you hear me? If you wake up, please hold my hand."

hand."
