general anesthetics
Total sedation drugs
General anesthetics are drugs that induce unconsciousness and loss of sensation throughout the entire body, typically administered before surgery.
They work by suppressing brain activity, allowing patients to undergo procedures without awareness or pain.
Delivered by inhalation or injection, they require careful monitoring: The anesthesiologist administered a general anesthetic before the operation.
Distinguished from local anesthetics, which numb only specific areas.
