What is anesthesia?

Anesthesia is a medical method used to prevent pain during surgical or diagnostic procedures by temporarily blocking sensation or awareness. It can be local, affecting a small area; regional, numbing a larger section of the body; or general, which induces unconsciousness. Anesthesiologists administer these drugs and monitor vital signs throughout the procedure. Common agents include gases, injections, or topical medications. Anesthesia allows doctors to perform complex surgeries safely without causing pain or distress. Afterward, patients are monitored as the drugs wear off. Proper management of anesthesia ensures patient comfort, safety, and smooth recovery.
