She answered so readily, which showed that this student was very confident. Du Yeqing's eyes flashed across Dou Rui's eyes and he instructed: "Do as she said, and adjust the heart rate to fifty beats per minute."
Dr. Pang adjusted the artificial heart-lung machine and the patient's heart rate increased again.
There was blood coming out again, and the surgical team had already targeted it. The separation forceps were immediately and accurately inserted into the bleeding area to separate the invisible crack. It happened that this crack led to the right ventricle and was very close to the mass attached to the ventricular wall on the CT film. The surgeon
The foreign body was immediately removed, and it was preliminarily judged to be a blood clot with the naked eye. For safety reasons, it was sent to the pathology department for a rapid pathological screening. During the suturing, the surgeon told the extracorporeal circulation specialist: "Continue to follow the heart rate she said."
Suddenly being entrusted with an important task by the teacher, Xie Wanying tensed her nerves.
Don't answer casually like answering academic questions. Stand up, observe and review the teacher's hand movement data and monitor data many times to estimate the rhythm of the surgeon's needle injection. After thinking about it, I suggested to Teacher Pang: "You can try to slow down to three."
The heart rate is fifteen beats per minute. The teacher’s movements are small but relatively fast.”
Dr. Pang adjusted the artificial heart-lung machine to make the patient's heart rate close to what she said.
Everyone looked at the monitor screen and saw that the surgeon's injection of the needle was almost consistent with the contraction of the right ventricle, and the movement of the needle was consistent with the relaxation of the right ventricle. This picture felt quite magical and wonderful.
It can only be said that Ye Qing did the right thing. It is a good thing to recruit a student who can touch his own head into the operating room.
After repairing the right ventricle, we came to the key point of the left ventricle. According to the plan, a coronary artery bypass graft was done here. First, a section of the internal mammary artery was taken to prepare the bridge. With the front ivus sentinel, the surgeon had a preliminary idea of which coronary vessel had the problem.
Judgment. Esophageal ultrasound is now used to determine whether there is a coronary artery fistula. The position of the esophageal ultrasound probe in the esophagus can be adjusted. Different lengths of penetration into the esophagus can detect different parts of the heart and great blood vessels. If it detects the left ventricle,
The probe needs to go deep into the esophagus about thirty centimeters, and a four-chamber view of the heart will appear on the screen of the ultrasound machine. Here you can see the valves, the left and right ventricles, and the left ventricular outflow tract.
The anesthesiologist operates and the surgeon observes. There is no abnormal blood flow signal in the ultrasound machine screen. If the result is correct, it proves that there is no fistula and only a bypass is needed.
There was silence in the operating room for a moment, everyone was hesitating whether Ye Qing's premonition was correct.
"Yingying, what do you think?"
It was Senior Brother Shen who asked her again.
Time was tight, so the senior brother only asked her. Anyway, her answer was that if the surgeon thought it could be used, she would use it, and if not, she would not use it. Xie Wanying did not hesitate and answered directly: "Try to move the probe back about 1 centimeter."
The anesthesiologist is super fast and can withdraw the probe directly without any instructions from the surgeon.
Doctors in large hospitals are very courageous and will respond instantly to any attempt without major risks.
As soon as he retreated, an abnormal blood flow signal appeared on the screen.
Phew, there were sounds of relief everywhere in the operating room. Because I know from Ye Qing’s experience that the chance of being wrong is very low, and it would be really terrible if I couldn’t find the problem quickly. For doctors, apart from the operations during surgery, the most difficult and most difficult thing is
Start looking for evidence.
If there is a fistula, this area should be treated precisely, sealing the leak and bridging it at the same time. The surgeon puts the prepared gasket on the fistula and sutures it.
After the two parts of the operation were completed, the time was fixed at thirty-three minutes, which was almost amazing.
