The surgery is performed step by step according to the steps discussed previously.
The three-dimensional mapping software is running. It is not uncommon for this method to be used in scar ablation. It is just that there is no stimulation now to avoid the risk of stimulation.
The current operation is to verify whether Xie's academic hypothesis is correct and feasible. The teachers present are also paying attention to this point.
At this time, no one can easily say who is lucky. After all, there has been an academic debate.
Ablation of the isolation zone begins. In addition to the location of ablation, the energy used in the depth of ablation needs to be carefully considered by the doctor to avoid burning through the perforation or not burning deep enough to cut off the abnormality.
The advice provided by Xie Wanying to the teacher is that the power is not consistent, there are high and low.
The surgeon had stopped talking for a long time. He carefully followed her instructions and slowly operated based on his own observations and inferences. It showed that it was not easy to do what she said. The nurse came up and wiped the sweat from the surgeon's forehead.
After the isolation band was done, the operation time passed an hour. This time was faster than the surgeons expected. It seemed to take a lot of time to discuss it back and forth. As a result, time was saved in the subsequent operation because the path was clear.
Now comes the most critical step. After the ablation is completed, a drug test is conducted to verify the effect.
"I'll push the medicine." Dai Ronghong volunteered.
Absolutely trusting in the abilities of her old friend, Dr. Che nodded.
Drug tests include isoproterenol test and ATP test. Isoproterenol will accelerate the heart rate, shorten the effective refractory period of myocardial cells and increase the excitability of slow-responsive cells, which can easily induce tachycardia. The specific usage is to use
Add two milligrams to 100 ml of normal saline and infuse intravenously at a slow to gradually high speed to a certain rate.
During the provocation test, everyone held their breath. If the ablation failed, the patient would need to be rescued at any time. People in the operating room were very nervous at first. The nurse prepared rescue equipment. Dai Ronghong, just in case, used the emergency equipment as soon as possible.
All the rescue medicines that arrive are put out first.
The defibrillator was placed beside the bed even though the defibrillation might fail again. Dr. Che called the temporary pacemaker and put it on the instrument table to stand by.
The eyes of everyone inside and outside the operating room almost wanted to be glued to the various values on the instruments and stare at them.
The second hand flashes one second on the wall clock on the white wall.
Seconds are like years.
After dripping almost half the bottle of liquid, everyone finally realized that the patient did not have tachycardia, and the occasional atrial tachycardia that the patient had previously had disappeared.
The three-dimensional software monitored the heart over and over again, and no abnormal high-pressure areas were found.
"Let's do another ATP test." Seeing that it was so successful, the doctors couldn't believe their eyes, and they all said excitedly, "Let's do another intracardiac EPS test."
EPS is an electrophysiological test. The previously mentioned mechanical stimulation on the endocardium induces tachycardia. The ATP test is also a drug test, and the administration method is intravenous injection.
After repeated verifications, it was finally concluded that the ablation effect was excellent. All the doctors were relieved of their heavy heart.
He happily went out to inform his family. When Dr. Che walked out of the operating room, he shouted: "Thank you, doctor. I'll treat you to dinner."
"No, I'll treat her to it."
When everyone realized who said this, Zhao Zhaowei and a group of classmates asked: Scared?
