Even today, craniotomy is risky. Before the operation, the doctor will definitely ask you or your family to sign a letter of commitment on medical risks and medical responsibilities. What's more, the ancient medical level and medical technology were seriously lacking? If I were Cao Cao, I'm afraid I have to doubt Hua Tuo's motives.
There are two issues involved here:
First, the ancients' cognition of body and medical treatment. Chinese medicine pays attention to "looking, listening and asking" and taking the pulse. Then write a prescription. Can be decocted into decoction for oral administration, or ground into powder for external application. Or we can solve the patient's pain through acupuncture. As for surgery, such historical records are rare.
Hua Tuo's medical books have not been handed down from generation to generation, and we don't know whether Hua Tuo really has the ability to do a brain surgery. But on the whole, Hua Tuo's medical skills, however brilliant, could not exceed the overall medical level of the same period by much. After all, it will be limited by the times.
Under such medical inheritance, it is generally difficult for someone to break through the limitations of medical means. Let alone let ordinary people undergo such surgery. Even if today's people give Hua Tuo the title of "Master of Surgery", it will not change the cognition of ordinary people in his time. Moreover, brain surgery is different from other surgical operations. This point, no matter when ordinary people understand, the head is always more important than the hands and feet, which is directly related to life.
The medical skill that most people understand is Chinese medicine treatment, even witch doctor. As for the medical skill of cutting and closing the human brain, I'm afraid it will surprise everyone. Will think this is a fantasy. Unless someone is in a hurry, I'm afraid no one will be willing to make fun of his life.
What's more, it's gone with the Three Kingdoms. For ordinary people, it is lucky to survive. Who dares to try Hua Tuo's sharp axe with his own head? Even though he's called an imperial doctor.
Second, is Hua Tuo's medical skill really up to the point where he can perform brain surgery? Hua Tuo invented "Mafeisan", a drug that can be anesthetized. But it is hard to say whether this medicine is used to solve the pain of patients during the operation or to alleviate the pain of patients suffering from the disease itself.
Although I am not a doctor and have not studied medical knowledge systematically, I am afraid that Hua Tuo can't solve some common medical problems. For example, even if anesthesia can be implemented, how to deal with massive bleeding? How to solve the intracranial pressure problem after craniotomy? How to prevent postoperative wound infection?
These were all unsolvable under the medical skills at that time. Just solving an anesthesia problem does not mean that the operation can be carried out. Take another 10,000 steps. Even if Hua Tuo solves all these problems, can the operation still be carried out?
Without the help of modern medical equipment and a huge scientific medical team, can Hua Tuo ensure the success of the operation only by his own strength and a sharp axe, even with Ma Feisan?
Even if Hua Tuo once had a successful medical experiment, what is the probability of success? Did one monkey in 1000 survive, or did one monkey in1000 survive?
Even if Hua Tuo can achieve a success rate of 10% (although it is almost impossible, let's assume power), as Cao Cao, it is tantamount to putting his life in Hua Tuo's hands. You know, Cao Cao's life is not only his own, but also related to the political situation of the whole three countries. Even if Cao Cao dares to take the risk, his gang will not agree. What's more, Cao Cao is not a reckless person.
Therefore, no matter who, in that case at that time, would not choose to believe Hua Tuo. After all, everyone has only one head. Who wants to make fun of this head?
