The primary difference between General Anaesthesia (GA) and Local Anaesthesia (LA) lies in the extent of the body affected and the patient’s state of consciousness during the procedure.
Comparison Table
| Feature | General Anaesthesia (GA) | Local Anaesthesia (LA) |
|---|---|---|
| Consciousness | Results in a reversible loss of consciousness. | Patient remains fully conscious. |
| Mechanism | Involves unconsciousness, amnesia, analgesia, and muscle relaxation. | Targets a small, specific area of the body via infiltration or topical application. |
| Typical Use | Used for major thoracic or abdominal surgeries requiring muscle relaxation and controlled respiration. | Used for minor procedures confined to a single, small site. |

General anaesthesia is a systemic approach that affects the entire body, whereas local anaesthesia is restricted to a specific site. Before inducing GA, it is mandatory to assess airway risk.
