During this period, Cao Zhao crossed his hands on the student's chest and continued to press 100 to 120 times per minute.
Picking up the two electrode pads from the defibrillator, Cao Dong shouted to everyone: "Get out of the way!"
It's time to defibrillate. Cao Zhao was forced to stop.
Everyone gave up their positions.
The two electrode plates were immediately placed on the right sternum and the apex of the patient's heart, and they were discharged against the clock.
After the first blow, the cardioversion failed. Two hundred joules should be prepared for the second blow.
Some people at the scene saw this situation and their legs went limp again, and all the medical students knew what it meant if electric defibrillation didn't work.
As mentioned before, electrical defibrillation is not effective for rescuing all heart disease patients, and it has its indications.
Putting it on the current patient, the electrocardiogram connected to the instrument shows a rapid ventricular tachycardia heart rate, which is supposed to be effective. If it does not work, one reason may be that the energy is not large enough, the operator can increase the charging energy to 200 and try again. If the second blow fails, the effect of defibrillation must be re-estimated and the consequences must be reconsidered.
There was a patient who was in ventricular electrical storm, that is, recurrent ventricular tachycardia or ventricular fibrillation within 24 hours. During the rescue period, medical staff performed 100 times of electrical defibrillation to bring him back to life. This 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 a typical myocardial infarction.
For patients whose etiology is not clear, if electrical defibrillation fails to achieve successful electrical conversion, the doctor needs to carefully analyze the cause for research and judgment. Whether defibrillation can be given again, it must be considered that electrical defibrillation is not completely free of side effects. Electric defibrillation acts directly on the heart. If it doesn't work, no one can guarantee whether it will cause adverse consequences to the heart if it is imposed multiple times.
The choice has always been the biggest problem facing doctors in rescuing patients.
The indications of the defibrillator are not a panacea, and death can never be easily dealt with.
Under the current rescue, doctors can only think about conventional medical measures according to the medical procedures, and it is safest to follow the steps.
Defibrillation didn't work, so I quickly continued to do chest compressions, and simultaneously took cardioversion and emergency medicine.
Relevant rescuers ran into the dispensing room, rushed out with boxes of commonly used first-aid medicines and put them on the ground, and asked the doctor, "What medicine to give?"
No boss responded.
What medicine are you pushing? According to clinical experience, electrical defibrillation is the most effective measure to deal with abnormal ventricular electrical activity, with minimal side effects. For cardioversion with drugs, cardioversion drugs have always had serious side effects, and doctors want to use them well, like walking on thin ice.
Simply put, cardioversion drugs are to restore the heart rhythm to a normal state, and one of them must be to bring the heart rate down. It can often be seen in clinical practice that under the condition of slowly pushing cardioversion drugs by hand at a slow speed, the patient's heart rate in the first second can suddenly change from a heart rate of more than 100 to less than 60 in the next second. This is what happens in patients with a clear cause, not to mention what would happen if such a drug were given to a patient with an unknown cause.
Once you push a wrong medicine, it will either save people or push the patient to death.
The patient in front of him was his student, so the big guy didn't dare to act rashly.
Consider it, and do so very carefully.
