Assessing Anesthesia Risks to Make Surgery Sleep Safe

For a long time, people have a misunderstanding of surgical anesthesia, believing that “anesthesia has no technical content, nothing more than an injection, and the patient sleeps”.
This is far from the truth.
If surgery is risky, anesthesia is even riskier.
Anesthesiology is a clinical subject with high professional requirements for practitioners, and it is the pioneer of modern medicine.
Anesthesiologists are the protectors of surgical patients and the heroes behind the scenes to ensure the smooth operation.

In addition to the traditional open surgery in modern surgery, there are also rapidly developing and mature minimally invasive surgery.
Minimally invasive surgery using laparoscopy, thoracoscopy, arthroscopy, hysteroscopy, cystoscope and other modern medical instruments and related equipment to carry out surgery.
Whether traditional surgery or minimally invasive surgery, the choice of different surgical methods, the way of anesthesia is different.
For general anesthesia, general anesthesia allows the human body to quickly enter the completely ignorant state of undergoing surgery from the fully awake state, without pain, consciousness, muscle relaxation, at the same time, spontaneous breathing may be suspended, and hemodynamics may be significantly fluctuated by the influence of drugs.
Besides, surgery is a treatment process as well as a trauma process, which will significantly stimulate the body’s physical signs and aggravate the risk of anesthesia.

Because the operation site is different, the operation method is different, the anesthesiologist must have the “eighteen martial arts”, master the various monitoring means, according to the patient’s different situation and complications, make a good plan in advance, and prepare all kinds of rehydration, dopamine, norepinephrine, anti-arrhythmic drugs and other kinds of rescue drugs.
Patients on the operating table vital signs are subject to the ups and downs, severe cardiac arrest, then need to anesthesiologists responsiveness, timely detection, timely treatment, at the same time, the anesthetic dose also needs to constantly adjust according to operation progress and additional, therefore, for the operation, the butcher physician is responsible for the patients with surgical effect, anesthesiologists is responsible to the life safety of the patients on the operating table.

How do anesthesiologists assess the patient’s risk of anesthesia before surgery?
The American Society of Anesthesiologists (ASA) classifies the safety of anesthesia into five levels before anesthesia according to the patient’s physical condition and the risk of surgery.
The author made a comprehensive judgment based on the patient’s past history, chief complaint, symptoms, physical examination, physical diagnosis and laboratory examination, and summarized “3 30”, which is conducive to more direct judgment of the patient’s tolerance and risk of anesthesia.

The first “30” is the breath-holding test. If the patient can hold his or her breath for more than 30 seconds, especially after the end of the exhalation, then breathing function is acceptable.
The second “30” is whether to go up continuous steps (in the middle can be at ease once or twice) more than 30 steps, not gasp, not palpitation, that heart function is OK.
The third “30” is whether you can easily walk on flat ground for more than 30 minutes. If you do not have shortness of breath or fatigue during walking, it indicates that your basic metabolism is good.
If “3 30” can be achieved, then the physique basically reaches the first or second level of anesthesia ASA grading standard, that is, anesthesia and surgery tolerance is good, anesthesia is relatively stable.
