The optical tweezers were replaced three times, which sounds like someone was not comfortable with the instrument and was forced to change it. This means that someone's skills may not be up to standard and unreliable.
The problem is that this phenomenon did not occur in an unreliable hospital but in the most reliable neurosurgery hospital.
All I can say is that maybe Pan counted the wrong number.
Probably not.
If so, a group of Fang Ze people at the scene would start cursing and jumping up and down. How could they allow someone to deliberately be blind and cause trouble in their own operating room?
That’s strange, has it really changed? Why change?
You need to study it further and don't jump to conclusions.
The monitoring device beeped twice, and the numbers indicating the patient's vital signs jumped out of the normal range, which quickly aroused the doctor's vigilance.
The anesthesiologist instructed the nurse to bring the prepared blood bag and hang it on the infusion stand.

For patients with large craniotomy windows like this, a large amount of bleeding is inevitable as the operation time accumulates. This means that the current situation is under the control of the doctors and there are no major changes.
Blood transfusion can stabilize the patient's blood pressure. However, as mentioned before, in order to stabilize blood pressure during surgery, the first condition must be adequate hemostasis to stop the bleeding. The surgeon did not take the situation lightly, but carefully observed the common bleeding spots and performed hemostasis.
Each surgical specialty has its own set of specialized technical characteristics. Not to mention the advanced technology, there may be significant differences in the basic surgical techniques. Neurosurgery is such a special department. As mentioned before, when cutting the scalp, due to the anatomical characteristics of the scalp with rich blood vessels, neurosurgeons must use special incision methods such as the cross method or the arc method.
Similarly, ligation for hemostasis, which is often seen in general surgery, has become a minority use scenario in neurosurgery, and is mainly used only for ligating the blood supply to the lesion area. Therefore, in the neurosurgery operating room, it is relatively rare to see a group of doctors tying surgical knots and dancing with their hands, looking beautiful and handsome like in the general surgery department.
The common scene of hemostasis in the neurosurgery operating room is that the TV dramas do not deceive people. Scenes like this are often shown on TV, showing brain surgeons holding sponges. This is a common sight in neurosurgery operating rooms.
Sponge sheets are quite special in neurosurgery. What is special about them? Because brain tissue is extremely fragile, direct electrocautery and ligation may cause harm. The safest way is to use sponge compression to stop bleeding.
Even the suction method commonly used in surgical operations, during craniotomy, the doctor cannot hold the suction head of the suction device on the brain tissue to suck, and needs to suck blood through the sponge.
In this way, the sucked blood, exudate, secretions and other things are not directly sucked into the suction tube and into the drainage bottle, but are sucked onto the sponge. As a result, because the absorption capacity of a thin piece of sponge is limited, doctors have to frequently replace the full-load sponge during surgery.
Well, the doctor has to replace one piece after another. Such repetitive operations will undoubtedly increase the doctor's procedures and workload, prolong the operation time, which is obviously not good for the patient, especially when heavy bleeding needs to be stopped quickly, it is fatal.
what to do?
Based on this, the best neurosurgeons invented gelatin sponge. The amount of blood absorbed by gelatin sponge can be dozens of times that of ordinary sponge.
