General anesthesia is a medical treatment that uses medications to induce a state of unconsciousness in patients during surgical procedures. This allows doctors to perform operations without the patient feeling pain or being aware of the procedure. The medications can be administered through an intravenous line or inhaled as gases. During general anesthesia, a anesthesiologist or nurse anesthetist monitors the patient's vital signs, such as heart rate and breathing, to ensure safety. Once the procedure is complete, the anesthesia is stopped, and the patient gradually wakes up in a recovery area, where they are closely observed until they are stable.
