General anesthetics are medications used to induce a state of unconsciousness and lack of sensation during surgical procedures. They work by affecting the central nervous system, allowing patients to undergo operations without experiencing pain or awareness. These anesthetics can be administered through inhalation or intravenous injection, depending on the procedure and patient needs. The use of general anesthetics is carefully monitored by an anesthesiologist or nurse anesthetist, who ensures the patient's safety throughout the surgery. Common examples of general anesthetics include propofol, sevoflurane, and isoflurane. Recovery from general anesthesia typically involves a gradual return to consciousness and sensation, with patients often feeling groggy for a short period afterward.
