Administering a local anesthetic injection to a patient, or anesthetizing the patient into a coma, colloquially known as general anesthesia, is just the most basic, simplest task of an anesthesiologist.
The technical content is not very high.
Anesthesiologists are truly called guardians of life because they can provide patients with various life supports.
They can anticipate various crises in advance, thus the entire perioperative safety is under their control.
During the surgery, if unexpected events occur – the patient has an allergic reaction, sudden cardiac arrest, respiratory failure, a sharp drop in blood pressure, or a severe decline in blood oxygen... any issue related to life signs that patients encounter during surgery requires them to provide a solution immediately.
If the patient has a sudden cardiac arrest, then immediate cardiac resuscitation is necessary.
If ventricular fibrillation occurs, then defibrillation is mandatory.
