During this period, Cao Zhao crossed his hands on the student's chest and continued to press frantically one hundred to one hundred and twenty times per minute.
Picking up the two electrode pads that had been glued on the defibrillator, Cao Dong shouted to everyone: "Get out of the way!"
It's time to defibrillate. Cao Zhao was forced to stop.
Everyone quickly gave up their positions.
The two electrode plates were immediately placed on the right side of the patient's sternum and the apex of the heart, and they raced against time to discharge and make a sound.
After the first blow, the restoration failed. For the second blow, prepare two hundred joules.
Some people at the scene felt their legs weak again when they saw this situation. All medical students knew what it meant if the electric defibrillation was ineffective.
As mentioned before, electric defibrillation is not effective in rescuing all heart disease patients. It has its indications.
In the current patient, the electrocardiogram connected to the instrument shows a rapid ventricular tachycardia heart rate, so it should be effective. If it doesn't work, one reason may be that the energy is not strong enough. The operator can increase the charging energy to 200 and try again. If the second blow still fails, the effects and consequences of defibrillation must be re-estimated.
There was a patient who suffered from ventricular electrical storm, that is, repeated episodes of ventricular tachycardia or ventricular fibrillation within 24 hours. During the rescue period, medical staff performed defibrillation a hundred times to save his life. This situation is a very, very special case. Medical staff must have an accurate diagnosis of the patient before performing multiple electrical defibrillations. For example, this patient has abnormal cardiac electrical activity caused by typical myocardial infarction.
For patients whose cause is not clear, if defibrillation fails to achieve successful electroconversion, doctors need to carefully analyze the reasons and make judgments. Whether defibrillation can be given again depends on the fact that electric defibrillation is not completely free of side effects. Electrical defibrillation acts directly on the heart. If it is ineffective, no one can be sure whether repeated defibrillation will have the opposite adverse consequences on the heart.
Choice has always been the biggest problem faced by doctors in rescuing patients.
The indications for defibrillators are not omnipotent, and the God of Death is never easy to deal with.
Under the current rescue situation, doctors can only think of conventional medical measures according to medical procedures, and step by step is the safest.
If defibrillation is ineffective, chest compressions should be continued immediately, and drug cardioversion and rescue drugs should be administered simultaneously.
The relevant rescue personnel ran into the dispensing room, rushed out with boxes of commonly used rescue medicines, placed them on the ground, and asked the doctor: "What medicine should I use?"
No boss responded.
What medicine should I recommend? According to clinical experience, electric defibrillation is the most effective measure to deal with current abnormal ventricular electrical activity, with minimal side effects. If you use drugs for cardioversion, cardioversion drugs always have serious side effects, so doctors are trying to walk on thin ice if they want to use them properly.
Simply put, cardioversion drugs are used to restore the heart rhythm to a normal state, and one of them must be to slow down the heart rate. It is often seen in clinical practice that when cardioversion drugs are pushed slowly and slowly by hand, the patient's heart rate can suddenly change from over 100 to less than 60 in one second. This is what happens in a patient with a known cause, let alone what would happen if such a drug was given to a patient with an unknown cause.
If you recommend a wrong medicine, you will either save the patient or push the patient to death.
The patient in front of him is his student, and even a big boss would not dare to act rashly.
To consider, be sure to consider very carefully.
