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 was about to be defibrillated. Cao Zhao was forced to stop.
Everyone quickly gave up their positions.
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 cardioversion failed. For the second blow, 200 joules should be prepared.
Some people at the scene felt their legs weak again when they saw this situation. All medical students know what it means if the electric defibrillation is ineffective.
As mentioned before, electric defibrillation is not effective in rescuing all heart disease patients. It has its indications.
On the current patient, the electrocardiogram connected to the instrument shows a rapid ventricular tachycardia heart rate, which is theoretically 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 still fails, the effects and consequences of defibrillation must be re-estimated.
There was once 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
Before performing multiple electric defibrillations, personnel must have an accurate diagnosis of the patient. For example, this patient has abnormal cardiac electrical activity caused by typical myocardial infarction.
For patients whose cause is not clear, if electric defibrillation fails to achieve successful electroconversion, doctors need to carefully analyze the reasons and make judgments. Whether defibrillation can be given again must be taken into consideration that electric defibrillation is not completely without 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, continue chest compressions immediately, and simultaneously use pharmacological cardioversion and administer rescue drugs.
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.
Which drug should I recommend? According to clinical experience, electric defibrillation is the most effective measure to deal with the current abnormalities in ventricular electrical activity, with minimal side effects. When using drugs for cardioversion, cardioversion drugs always have serious side effects. Doctors want to use them like walking on thin ice.
.
Simply put, cardioversion drugs are used to restore the heart rhythm to a normal state, one of which must be to slow down the heart rate. In clinical practice, it is often seen that cardioversion drugs are administered slowly and slowly by hand.
, the patient's heart rate can be over 100 in one second and can suddenly change to less than 60 in the next second. This is what happens to patients with a clear cause, let alone if such a drug is used on a patient with an unknown cause.
What will be the result?
If you recommend a wrong medicine, you will either save the patient or push the patient to death.
The patient in front of me is my student, and even a big boss would not dare to act rashly.
