10 Frequently Asked Questions about Anesthesia

1. If anesthesia is not good, will it really kill people?

It’s possible.

Inadequate preparation for pre-anesthesia evaluation, selective errors in anesthesia schemes, errors in anesthesia operations, allergy to anesthetic drugs, and omissions in monitoring and management during anesthesia may all become anesthesia-related causes of patient death.

However, the anesthesia mortality rate is still very low, generally less than one in 10,000, and some 3A hospitals can even reach one in 200,000 to one in 300,000.

With the continuous updating and diversification of clinical anesthesia monitoring methods, the continuous improvement of anesthesia drugs, the standardization of anesthesiologist training and the improvement of sense of responsibility, anesthesia death is already a very rare situation with the most appropriate anesthesia scheme, so there is no need to worry too much.

2. Will general anesthesia affect children’s intellectual development?

In the past, there was no definite conclusion on whether general anesthesia would affect the intellectual development of infants at home and abroad. The latest research in the United States shows that general anesthesia surgery will not affect the intellectual development, cognitive function and behavioral performance of children under 3 years old (3 years old is an important stage of brain development) in the future.

There are also studies in China. The Pediatric Hospital Affiliated to Fudan University in Shanghai conducted cognitive function tests on 100 children aged 4-7 years old who underwent general anesthesia. The results showed that general anesthesia did not cause obvious damage to children’s cognitive function. [1]

However, for children with major congenital diseases and premature infants, whether narcotic drugs have any effect on the neurological development of children’s brains needs further research. This problem cannot be used to avoid necessary surgery, because life-saving surgery is often more important at these times.

3. Can I sleep on pillows after general anesthesia and semi-anesthesia?

The deep-rooted idea is not to sleep on pillows. But in fact, if the doctor does not give special instructions, he can sleep on pillows unless he does not sleep on pillows in his personal life habits.

For [hemp], that is, lumbar hemp, anesthesiologists in the past puncture needle on the patient’s back is relatively thick, lumbar hemp through arachnoid hole is relatively large, outflow of water, that is, cerebrospinal fluid natural more, may cause headache due to intracranial pressure reduction. Now the puncture needle is much more advanced and solves this problem.

When it comes to general anesthesia, doctors and nurses may explain to patients to prevent what they spit out of their mouths from being sucked in! But think carefully, which one breathes more smoothly, lying down or raising the head? Which one is more likely to choke yourself? Experts’ guidelines at home and abroad also point out that semi-decubitus position or head elevation is also conducive to rapid recovery after surgery.

4. Will memory deteriorate after general anesthesia?

It is possible, but it is not the fault of the narcotics.

Some patients feel hypomnesis after the operation. There are many possible reasons, such as cerebral hypoxia and ischemia caused by low blood pressure during the operation, tension and anxiety caused by surgical trauma, intuitive psychological feeling, etc.

Although some mouse experiments have found that large doses of anesthetic inhalation for a long time are associated with senile dementia. However, in actual surgery, it is impossible to use such large doses of anesthetic, and the operation time is much less than that used in the experiment. Moreover, anesthesia is controllable during the operation, and the metabolic elimination of anesthetic drugs is relatively fast and will not continue to affect.

At present, there is no evidence in what that narcotic drugs have a direct impact on human memory.

5. Why does the whole body shiver after general anesthesia?

Some patients will tremble all over their bodies after general anesthesia, causing their families to be very nervous. In fact, this is a normal phenomenon.

In a long operation time, the lower temperature in the operating room, blood transfusion, infusion, anesthesia factors, and the opening of the surgical wound will all lead to the loss of the patient’s own heat, and the patient is prone to hypothermia and postoperative chills.

For postoperative chills, it can be prevented or relieved by some measures during the operation, such as using thermal insulation blanket, inputting heating liquid, turning on the air heater, and covering other parts other than the operation part. Anesthesiologists will also prevent and relieve the postoperative chills of patients by using drugs.

6. Patients will be agitated after general anesthesia. What is going on?

Some patients will suffer from agitation after operation, which is roughly due to the following reasons:

General anesthetic drugs will be stopped with the end of the operation, and their analgesic effect will gradually decrease. Pain will cause involuntary agitation of patients.

Poor breathing, poor stimulation of catheter in airway, throat discomfort; The irritation of the catheter and the urination caused by it;

The anesthesia state suddenly turns to awake, but the residual effect of the drug and the conscious thinking are still temporarily affected, which is also easy to cause agitation.

7. Is anesthetic addictive?

No, it won’t.

Speaking of narcotics, It is easy for the average person to think of drugs that are easy to make people hallucinate. However, as a strictly controlled narcotic drug, with the progress of technology and drug improvement, the analgesic drugs currently used are fentanyl and its derivatives with strong analgesia and low addiction, and the dosage used during operation is also very small, which is within the absolute safe dosage range and will not produce addiction effect.

8. Why do you feel sore throat after general anesthesia?

Some patients will suffer from hoarseness, sore throat, especially dry mouth, and even discomfort such as blood in spitting after general anesthesia.

This is because during tracheal intubation, Tracheal tubes pass through the mouth and throat and are inserted into the air inlet. And the whole operation time is put inside until the end. Intubation this action, also may scratch the mucous membrane in the mouth or throat, if there are some difficult intubation patients, such as relatively fat, throat injury what, the incidence rate of this situation is higher. Of course, these conditions are usually only temporary, can return to normal in a short period of time.

With the wide promotion of visual laryngoscope, the postoperative comfort of patients will be further improved.

9. It’s scary. Can you endure pain without anesthesia?

You may have heard of customs clearance officials scraping bones to cure poison, Liu Bocheng picking eyeballs with pain, and other Jianghu legends. You may also wonder if not using anesthesia can save some surgical expenses.

However, what we want to say is that at least the operation performed in the operation room cannot be performed without anesthesia.

For the following reasons:

    Surgical operation will cause excessive stress reaction. As the saying goes, jumping up in pain will cause serious damage to the body. Although everyone’s tolerance to pain varies, the tolerance is limited and it is difficult to bear the pain of surgical degree. Anesthesia, as an indispensable condition for surgical operation, can make the patient in a good braking state, thus ensuring the surgeon to perform the operation with high quality.

10. How long can I get pregnant after general anesthesia?

As for the time problem, it has a great relationship with the recovery of the operation, but not with general anesthesia.

The general anesthetic drugs during the operation can be completely metabolized within a few days after the operation and removed from the body. All kinds of anesthetic drugs currently used are safe and reliable, and there are no reports and relevant data of human teratogenicity. Don’t worry too much.

Some operations may affect pregnancy in the future in terms of time, such as large abdominal surgery, which requires consultation with the surgeon and the advice of obstetricians and gynecologists. No special circumstances, several months after stable menstruation, pregnancy can be considered.
