What Can I Expect from General Anesthetic Recovery?

"Aesthetic awareness" means that the patient's motor nerves are paralyzed while the patient's consciousness is still awake when undergoing general paralysis during surgery. At this time, to the outsider, the patient will not respond to the outside world, but in fact His consciousness is sober. If surgery is performed in this state, every cut, ligation, puncture, medication ... the patient will feel it clearly. And terribly, there are about 60,000 a year in the United States alone. Man suffers the devastation of such a nightmare operation.

What happened

During general anesthesia

nickname

Intraoperative awareness

Under general anesthesia, human consciousness disappears, but there may still be cognitive activity in the brain. May occur in patients under anesthesia

In the past, general anesthesia was considered to be a rare complication of general anesthesia, but with the in-depth study of intraoperative awareness, especially implicit memory, and the continuous development of psychological testing methods, patients with general anesthesia

The influencing factors are more complicated. Most anesthesiologists believe that the influencing factors known during surgery are limited to the patient's age, gender, preoperative condition classification, the amount of anesthetic drug application, additional time, drug compatibility, etc., but as before

Ghoneim et al. (1997) analyzed the consequences known during the operation, and found that the two most common complaints of patients were the ability to hear various events and feel weakness or paralysis during the operation, and some patients were accompanied by pain. In particular, patients can recall conversations that are not good for them and their medical condition. The most reported postoperative symptoms are mainly sleep disorders, dreaming,

How to confirm the existence of cognitive activities under anesthesia? If the patient has a clear memory after anesthesia, which reflects the hearing or recall of bad speech and feeling during the anesthesia, and confirmed by the competent anesthesiologist, it can be confirmed that the patient has explicit memory under anesthesia.

Doing the following points carefully can basically avoid intraoperative awareness during general anesthesia.

1. All instruments need to be carefully inspected, and continuous inhalation of mixed gas needs to be monitored.

2. The anesthesiologist should be highly alert to the patients and instruments being monitored.

3. Benzodiazepines can be used as preoperative drugs, which is beneficial for patients with severe hemodynamic instability with shallow anesthesia for a long time.

4. Immediately intubate after succinylcholine administration, and the dose of inducer should exceed the "sleep dose".

5. Delay in intubation (or difficulty in intubation) or give non-depolarizing muscle relaxants, increase the dose of inducer or inhalation anesthetic.

6. Patients who do not need to be intubated should avoid muscle relaxants.

7. Apply an adequate amount of analgesics.

8. If you want to use N2O, it must reach at least 1.0 ~ 1.2MAC. If only inhaled anesthetic is used instead of N2O, the concentration of inhaled anesthetic should be at least 0.8 ~ 1.0MAC, and the concentration of end-expiratory anesthetic should be monitored.

9. Caution should be used in the application of intravenous anesthesia. Due to pharmacokinetic changes and the widespread distribution of drugs in patients, the drug concentration is reduced, but it is easier to know than inhaled anesthesia.
