Returning to ’90s, She Became Famous in Major Surgical Fields

   Chapter 1570 [1570] The problem of a big head

   Since many domestic advanced medical instruments are imported, the buttons on the machine are all in English, and doctors can identify them by being familiar with the English letter "AUTO".

   Treating patients with a machine is much more difficult than washing clothes with a washing machine at home. Sometimes we cannot use a fully automatic washing machine, and we need to adjust the parameters ourselves to wash some special clothes. Like a medical machine, the doctor will turn on the "OPENATOR" working mode and operate the machine by himself. Just like the automatic adjustment of parameters by machines, doctors use the human brain to distinguish the waveform values ​​to select the trigger mode to adjust the balloon inflation and deflation time and other operations.

   The same doctor's observation is from top to bottom, first look at the electrocardiogram. Some patients have arrhythmias themselves, such as sinus tachycardia, atrial fibrillation, etc. These conditions will affect the effect of counterpulsation. The most direct impact is the improper proportion of counterpulsation. Don't be afraid of this situation, as long as you adjust the appropriate counterpulsation ratio and balloon inflation and deflation time, it can be corrected.

   Let’s look at the arterial pressure of the red wave, which is usually the key graph that the surgeon needs to observe the most.

Like the electrocardiogram, the pressure graph loaded with the balloon pressure has a complete periodic change group by group. If the group of periodic changes in the graph appear to be superimposed or separated in advance like the electrocardiogram, Basically, it can be concluded that the problem of inflation and deflation is too early and too late. At this time, the doctor only needs to adjust the balloon inflation and deflation time on the machine.

   These are the problems that are relatively easy to judge and solve. The experienced Dr. Chen excluded them one by one, so he told the superior doctor that he had adjusted the machine parameters.

  The difficulty is that after the machine parameters are adjusted, it is found that the problem has not been solved. The pressure value after inflation of the balloon is not in place. If it is a non-machine parameter factor, other reasons that affect the counterpulsation effect cannot be solved by a light-adjusting machine.

  Needs a doctor to re-examine the balloon catheter that the machine connects to the human body.

  Adjusting the catheter is not like adjusting the parameters and simply pressing a few buttons on the machine, it is all a risky operation. Who wants to move the tube that has been placed in the patient's body again and again, what should I do if I get a sudden hemorrhage? In the case of systemic heparinization of the patient, there is a real risk of bleeding by tampering with the tube.

   is that the surgeon will have a big head thinking about it, how hope it is not.

  Shin Woo-hwan also hoped otherwise. If there is a problem, you can only face the reality and say to Dr. Chen, "You can try to move the top of the balloon back a little or stretch it forward a little."

  The position of the balloon is not in place, which leads to the failure of inflating the preset pressure, which is usually one of the factors affecting the effect of counterpulsation. Now looking at this arterial pressure waveform, this factor has probably disappeared.

   "I tried and it didn't work." Dr. Chen prayed that it was not, and answered.

"If it still doesn't work, you may need to change a larger or smaller catheter to try it out." Shen Youhuan cheered the people below, suddenly thinking of something, he turned his head to the little junior sister Xie Wanying and asked, "Do you have any ideas? "

   When asked by Brother Shen, Xie Wanying, who was also observing the operation, expressed her opinion: "As Brother Shen said, the top of the balloon can be stretched forward."

   "I said I tried it." Dr. Chen emphasized repeatedly.

   "Don't be too anxious." Xie Wanying said.

   Dr. Chen was stunned: a medical student told him not to be too anxious, did he hear it wrong?
