Chapter 3094 【3094】Special Way
The optical tweezers were changed three times. It sounded like someone was having trouble with the instruments and was forced to change them, which meant that someone's skills might not be very good or reliable.
The problem is that this phenomenon does not happen in unreliable hospitals, but in the most reliable neurosurgery hospitals.
It can only be said that whether student Pan counted the wrong number.
Probably not.
If so, a group of Fangze people at the scene would start yelling and jumping, how could they allow someone to intentionally go blind and cause trouble in their own operating room.
Strange, really changed? Why change?
More research is needed, so don't jump to conclusions.
The monitoring instrument made two beeps, beeps, and the number symbolizing the patient's vital signs jumped out of the normal range, which quickly aroused the vigilance of the doctor.
The anesthetist instructed the nurse to put the prepared blood bag on the infusion stand.
For patients with such a large craniotomy window, it is inevitable to accumulate more bleeding during the 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 the 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 observed the usual bleeding points and stopped the bleeding.
Each surgical specialty has its own set of specialized technical characteristics, not to mention advanced technology, there may be significant differences in the part of basic surgical technology. Neurosurgery is such a special department, such as the incision of the scalp mentioned earlier, based on the anatomical characteristics of rich blood vessels in the scalp, neurosurgeons must use the special incision method of cross method or arc method.
In the same way, ligation and hemostasis, which is often seen in general surgery, has become a minority usage scenario in neurosurgery, and it is mainly used only to ligate the blood supply of the lesion area. Therefore, in the neurosurgery operating room, it is relatively difficult for us to see a group of doctors in the general surgery department dancing with surgical knots, beautiful and handsome.
The hemostatic scene in the neurosurgery operating room is a common sight, but the TV series did not deceive people. The scenes that are often shown on TV show brain surgeons holding sponges, which are really common sights in neurosurgery operating rooms.
Sponge sheets are special in neurosurgery. Because the brain tissue is very fragile, direct electrocautery and ligation are often used to cause injury. The safest way is to stop bleeding by compressing the sponge.
Even the suction method commonly used in surgery, in craniotomy, the doctor cannot hold the suction head of the suction device on the brain tissue to suck, but needs to suck blood through the sponge sheet.
In this way, the blood, fluid, secretions and other things sucked out are not directly sucked into the suction tube into the drainage bottle, but are sucked onto the sponge sheet. As a result, because the capacity of a thin piece of sponge sheet to absorb and carry is limited, doctors have to 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 procedures and workload of many doctors and prolong the operation time, which is obviously not conducive to the patient, especially when the bleeding needs to be stopped quickly.
what to do?
The pinnacle of neurosurgery doctors invented the gelatin sponge accordingly. The blood absorption capacity of gelatin sponge can reach dozens of times that of ordinary sponge.
