Local Anaesthesia vs. General Anaesthesia: Know the Difference
By Shumaila Saeed || Published on February 1, 2024
Local anaesthesia numbs a specific area without affecting consciousness; general anaesthesia induces unconsciousness and total lack of sensation.
Key Differences
Local anaesthesia is used to numb a small, specific area of the body. In contrast, general anaesthesia affects the entire body, causing loss of consciousness. Both are used for different types of medical procedures.

With local anaesthesia, the patient remains fully awake and aware, but the targeted area is desensitized. General anaesthesia, however, results in complete unconsciousness and is used for more invasive surgeries.
