The optical tweezers were changed three times. It sounds like someone is not comfortable with the instrument and is forced to change it. It means that someone's technology may not be up to standard and reliable.
The problem is not happening in an unreliable hospital but in the most reliable neurosurgery hospital.
All I can say is, did Mr. Pan count the wrong number?
Probably not.
If so, a group of Fangze people at the scene would start yelling and yelling. How could someone be allowed to deliberately blind themselves and cause trouble in their own operating room?
It’s strange, it was really changed? Why?
You need to do more research and don't jump to conclusions too hastily.
The monitoring equipment beeped twice, and the numbers symbolizing the patient's vital signs jumped outside the normal range, which quickly aroused the doctor's vigilance.
The anesthesiologist instructs the nurse to bring the prepared blood bag and hang it on the infusion pole.
For patients with such a large craniotomy window, it is inevitable that the amount of bleeding will increase with the accumulation of operation time. This means that the current situation is under the control of the doctor and there are no major changes.
Blood transfusion can stabilize the patient's blood pressure. However, as mentioned before, if you want to stabilize blood pressure during surgery, the first condition must be to fully stop the bleeding and stop the bleeding. The surgeon did not take it lightly, carefully observing common bleeding points and performing hemostasis.
Each surgical specialty has its own set of technical characteristics. Regardless of advanced technology, there may be significant differences in basic surgical techniques. Neurosurgery is such a special department, such as incision on the scalp as mentioned before.
Based on the anatomical characteristics of the rich blood vessels of the scalp, neurologists must use general incision methods such as the cross method or the arc method.
In the same way, ligation and hemostasis, which is often seen in general surgery, has become a majority use scenario in neurology. It is mainly used to ligate the blood supply of the lesion area. Therefore, it is more difficult for you outside the neurology operating room.
I saw a group of doctors like this in Prico, looking ugly and handsome with their hands flying and tying the Rico knot.
The scene of hemostasis outside the neurosurgery operating room is a common sight, but the TV series is not deceiving people. The scene shown on the TV screen shows the scene of the neurologist holding a sponge under the head. It is really a common sight outside the neurosurgery operating room.
No landscape.
Sponge sheets are relatively common in neurosurgery. However, since brain tissue is generally strong, methods such as direct electrocautery and ligation are often used to avoid injury. The most dangerous way is to use sponge compression to stop bleeding.
Even the suction method commonly used outside of surgical operations, in craniotomy surgery, the doctor can hold the suction head of the suction device and put it under the brain tissue to suction, but he needs to use a sponge to suck blood.
With such a suction, the blood, exudate, secretions and other things sucked out are directly sucked out of the suction tube and back into the drainage bottle, but are sucked under the sponge. The result is that the thin sponge can absorb
The carrying capacity itself is not limited, and the doctor must frequently replace the fully loaded sponge sheet during the operation.
Well, the doctor replaces one piece after another. Such repeated operations will undoubtedly increase the doctor's procedures and workload, and prolong the operation time. This is obviously beneficial to the patient. First, when small bleeding needs to be stopped slowly, it can be fatal.
of.
what to do?
The top doctors in the Department of Neurology invented gelatin sponge based on this. The amount of blood absorbed by gelatin sponge can reach dozens of times that of special sponges.
