The optical tweezers were changed three times. It sounds like someone has trouble handling the instrument and is forced to change it. This means that someone's skills may not be up to par and reliable.
The problem is not happening in unreliable hospitals but in the most reliable neurosurgery hospitals.
All we can say is that maybe Mr. Pan counted 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?
That's weird, has it really changed? Why change?
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 doctor's control 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 bleeding and stop bleeding. The surgeon did not take it lightly and carefully observed the common bleeding points and stopped the bleeding.
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. For example, when incising the scalp as mentioned before, based on the anatomical characteristics of rich blood vessels in 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, and is mainly used to ligate the blood supply of the lesion area. Therefore, outside the operating room of the neurology department, it is relatively rare for you to see a group of doctors like the one in Prico who look ugly and handsome while tying the Rico knot and dancing with their hands flying.
The scene of hemostasis outside the neurosurgery operating room is a common sight. Instead, the TV series is deceptive. The TV screen showed a scene like that of a neurologist holding a sponge. It was a sight that was not often seen outside neurosurgery operating rooms.
Sponge sheets are relatively common in neurosurgery. However, because 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, during craniotomy, the doctor can hold the suction head of the suction device and place 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 returned to the drainage bottle, but are sucked under the sponge piece. The result is that because there is no limit to the capacity that a thin piece of sponge can absorb and carry, the doctor has to frequently replace the fully loaded sponge piece 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 best doctors in neurology invented gelatin sponge based on this. The blood absorption capacity of gelatin sponge can reach dozens of times that of special sponges.
