The catheter is also too thick for the child's bronchi.
Let me talk about again why Dr. Liu Yu reminded Student Xie.
When obstetricians make their own water bags, they do so in a completely visual environment. The doctor can clearly see how big the water bag should be and what shape will best fit the patient's uterine wall to stop bleeding.
Otherwise, a balloon like the one used in interventional endoscopic surgery would be needed, such as the hemostatic balloon originally invented in obstetrics and the various balloons currently in use. There is a tube connected to the balloon to slowly pressurize the balloon. Otherwise, if the balloon is too large or too small, it will not have any hemostatic effect.
What is the prerequisite for compression hemostasis in the lumen? Adequate packing.
Because the doctor's hands cannot enter, in order to fully press on the bleeding surface, he can only rely on the lumen's own volume contraction ability to apply pressure to the bleeding surface.
If the doctor cannot fully estimate the volume and shape of the bleeding part, and uses a capsule of the wrong size or shape, it may result in the capsule not being able to enter the cavity, or the capsule being too small to press on the bleeding surface.
All I can say is that Dr. Liu Yu didn't know Ms. Xie very well, so he had concerns about whether she could do it.
The big boss Zhang Huayao doesn't seem to have this worry at all.
...
...
No, the boss is really "making things difficult" and won't remind you. If you can't do it, step down. There's nothing to say.
"Be careful, there may be more than one bleeding point."
When this voice suddenly appeared on the operating table, everyone's eyes fell on the cold forehead and eyebrows of the person who spoke - it was Fu Xinheng.
Zhang Huayao's eyes narrowed slightly: Cao Yong didn't say anything, and you, a robot, actually spoke?
Cao Yong was worried about something different from him.
What Cao Yong always worries about most is that she overuses her brain.
What Fu Xinheng was thinking was: Why should the interns of our hospital be tested like this by you, Guozhi? If there is any test, it should be our own teachers from the National Association. Are you Guozhi looking for trouble with the National Association? Do you think that the teachers from the National Association can't teach this student well? He has been very unhappy about this for a long time.
After all, he is the heart of Guoxie, and he happens to be a competitor of your Guozhi. He is definitely a hundred times more sensitive to this than Cao Yong.
Liu Yu was calm and could feel the subtle atmosphere on the operating table. As a dentist at the National Association for the Treatment of Stomatology, he had frequent contact with Guozhi and people outside the National Association for the Treatment of Stomatology due to business relations, and was fully aware of how strong and terrible the competition between the two units was.
In such a situation, medical students might be caught in a dilemma. Would they be scared to death?
No. A stubborn person would only answer like this: "Thank you, Mr. Fu."
Then, Xie Wanying quickly adjusted the shape of the homemade balloon. Teacher Fu was right. We should fully consider the possibility that the wound would be lengthened or a smaller wound would be added if the foreign body was clamped out.
The nurse standing nearby saw her making it and couldn't help but praise her: "You have such deft hands."
The other doctors heard this and looked at what she was holding.
Cut out a glove finger fragment, use surgical sutures to quickly tie a circle on the tail, inject saline into it, and form a slightly longer cylindrical water bag. Then follow the teacher's instructions and add two small cylindrical tails. The child's bronchi are small, and the diameter of the water bag cross section must be very small, so it is necessary to control each value.
