For centuries, surgery was frequently a painful process. Anesthesiologists are able to make surgeries almost painless because to medical developments. Except in cases of emergency, the anesthesiologist normally consults with the patient prior to surgery. The doctor will inquire about the patient's medical history, as well as describe the type of anaesthesia that will be used and any potential adverse effects. Before the operation, the doctor provides anesthesia...and checks to see if it is working. The anesthesiologist keeps track of the patient's vital indicators, which include heart rate, blood pressure, body temperature, and breathing. To ensure that the patient is sufficiently sedated, the dose of anaesthetic may need to be modified on a regular basis. It's a mentally taxing and high-pressure job. This doctor is in charge of the patient's life. The majority of the work is done in operating rooms at hospitals or surgical outpatient centres. They may also be in charge of pain management in intensive care units and during childbirth. Hours might be erratic and long. Even after the procedure, anesthesiologists continue to monitor patients to ensure they recover from anaesthesia properly. Following medical school, anesthesiologists complete a four-year residency programme. Following residency, they may seek fellowship training in subspecialties like as cardiothoracic anaesthesia and critical care. Every year, millions of surgeries are carried out. Many of them would be impossible to do without the knowledge and experience of anesthesiologists.
