During this period, Cao Zhao crossed his hands on the student's chest and continued to press frantically for 100 to 120 times per minute.
Picking up the two electrode pads on which the defibrillator spit glue, Cao Dong called everyone: "Get out of the way!"
I'm going to defibrillate. Cao Zhao was forced to stop.
Everyone swoops out of position.
The two electrode pads were immediately placed on the right side of the sternum and the apex of the patient's heart, racing against time to discharge and make a sound.
After the first blow, the cardioversion failed. Two hundred joules to prepare for the second blow.
Some people at the scene saw this situation and their legs became weak again. All the medical students knew what it meant when the defibrillation didn't work.
I have said before that electrical defibrillation is not effective for all heart disease rescue patients, it has its indications.
On the current patient, the ECG connected to the instrument shows a fast ventricular tachycardia heart rate, which is reasonable to say that it can 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 does not work, then the defibrillation should be re-estimated and the consequences should be considered.
Once a patient was in a ventricular electrical storm, that is, ventricular tachycardia or ventricular fibrillation that recurred within 24 hours. During the rescue period, the medical staff performed defibrillation for 100 times. Such a situation is a very, very special case. Before performing multiple electrical defibrillation, medical staff must have an accurate diagnosis of the patient. For example, this patient is a typical myocardial infarction caused by abnormal cardiac electrical activity.
For patients without a clear cause, if electrical defibrillation does not play a role in successful electrical cardioversion, the doctor needs to carefully analyze the reasons for research and judgment. Whether defibrillation can be given again, it is necessary to consider that electrical defibrillation is not completely without side effects. Electrical defibrillation acts directly on the heart. If it does not work, if it is repeatedly imposed on the heart, it will cause the opposite adverse consequences. No one can guarantee this.
The choice has always been the biggest problem facing doctors in rescuing patients.
Defibrillator indications are not omnipotent, and death has never been easy to deal with.
Under the current rescue, doctors can only think about routine medical measures according to medical procedures, and it is safest to follow steps.
The defibrillation is ineffective, so continue to do chest compressions immediately, and simultaneously take drug cardioversion and push rescue drugs.
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?"
No bosses responded.
What medicine are you pushing? According to clinical experience, electrical defibrillation is the most effective measure to deal with the current abnormal ventricular electrical activity, with the least side effects. If you use drugs for cardioversion, cardioversion drugs have always had serious side effects. Doctors want to use them well, such as walking on thin ice.
In simple terms, cardioversion drugs are to restore the heart rate to a normal state, and one of them must be to beat the heart rate down. In clinical practice, it is often seen that under the condition that the patient's heart rate is above 100 in the first second, the heart rate of the patient can suddenly become below 60 in the next second under the condition that the cardioversion drug is slowly pushed at the speed of the turtle. This is what happens in patients with a clear cause, let alone what would happen if such a drug were given to a patient with no clear cause.
If you push a medicine incorrectly, it will not save the patient but push the patient to death.
The patient in front of him is his own student, and even a big boss would not dare to act rashly.
To be considered, to be considered very carefully.
