Doctor Yao could only look for evidence on the interns now, and he insisted asking: "Tell me, what did you do to the patient? I saw that you peeled off the film of the incision and performed chest compressions on the patient. Did you change your gloves?" Maybe it was a false rescue alarm signal made up by these interns.
Dai Nanhui was the first one who couldn't accept the dirty water being thrown at him. He almost exploded and shouted: "We ran over from next door to rescue people because we heard the alarm."
"Cold and quiet." These two words burst out from the mouth of the immortal brother Cao Zhao.
This is to calm everyone's mind, including their own students and Dr. Yao.
In any case, as a doctor, first of all, you have to find out what happened to the patient and whether the patient's life is in danger. Then you can figure out who is responsible for the rest.
Agreeing with the teacher, Xie Wanying said calmly, "I peeled off the protective film of the incision to make sure that the electrodes of the pacemaker wires were connected to the patient's epicardium and did not fall off."
pacemaker?
Pacemakers. Maybe now that more people are undergoing interventional surgery, we only know that pacemakers are related to interventional surgery. In fact, when pacemakers were first used, they were not installed by interventional surgery, but by traditional surgery.
To be more specific, interventional surgery to install a pacemaker involves delivering electrodes to the heart cavity via peripheral veins and installing them in the endocardium. This procedure does not require opening the chest, reduces the patient's pain, and saves the trouble of surgical operations, and is widely popular in clinical practice.

Surgical installation of a pacemaker requires the doctor to open the chest pericardium and connect the electrodes to the epicardium of the heart, which is not favored by patients.
Intervention has many advantages. Surgical installation is too painful and the technology seems to be backward, so it can be eliminated by advanced intervention. Besides, what is the purpose of surgical installation?
That's not the case. In clinical practice, we always use whichever is more convenient and whichever is more suitable for the patient's treatment. To date, in pediatrics, surgery is the first choice for pacemaker installation in children under five years old. This is due to the characteristics of pediatrics that have been repeatedly emphasized: children will grow. You need to pre-place longer wires for children to grow taller. If interventional surgery is used, the wires that are too long cannot be placed in the heart or peripheral blood vessels. Some children have heart malformations, and interventional surgery is difficult to locate the electrode installation position, so they can only be installed through surgical means. Children are active, and surgery is not like interventional surgery, which must be fixed on the chest where the skin fat is thin and difficult to place. It would be better to fix it in other places where the skin fat is thick.
Similarly, since Xiaohui had an open-chest surgery today, if she needed to install a pacemaker, there was no need for intervention. It would be more convenient to directly install the electrodes on the epicardium during the open-chest surgery.
Speaking of which, why does Xiaohui need a pacemaker? Is this child's illness not something that requires a pacemaker?
A large part of the clinical use of pacemakers is for medical treatment. Most of these patients undergo interventional surgery and use permanent implantable pacemakers. Another type of application of pacemakers is temporary pacemakers used for rescue and backup, such as the last time when Mr. Lu was rescued.
Like Xiaohui, the surgeon gave her a pacemaker during the operation, fearing the possibility of something like Teacher Lu. Many patients who have undergone heart surgery have unstable circulation. The heart may stop suddenly during or after the operation. Installing a pacemaker can help doctors save the patient's life when doctors are unable to arrive in time to rescue him in an emergency.
