there are two main classes of anesthetics
1. General anesthetics
2. Local anesthetics
General anesthetics are used to produce general analgesia (total unconsciousness) that is utilized for surgery purpose.
eg. chloroform
Local anesthetics are used to produce analgesia (numbness) to local area of body (particular area)
eg, xylocaine

anaesthesia technology
Sensorcaine is a type of epinephrine injection. It is a local anesthetic agent and can only be taken via an injection.
For opthalmic local anaesthesia : it can be used as eye-drop to anaesthetize conrea or conjuctiva (due to its vasoconstrictive effect)
Local anaesthesia is typically used, as removing a tooth is a fairly short and simple procedure and it is simpler to have the patient awake during it. General anaesthesia might be used if the patient has a strong fear or intolerance of dentistry.
Annals of Cardiac Anaesthesia was created in 1998.
Indian Journal of Anaesthesia was created in 2002.
Anesthesia is a medically induced reversible state of unconsciousness, analgesia (pain relief), amnesia, and muscle relaxation that allows doctors to perform surgical or diagnostic procedures safely. It is caused by anesthetic agents that act on the central nervous system, altering nerve signal transmission. Mechanism: General Anesthetics – Depress the brain and spinal cord activity, leading to loss of consciousness and sensation. Local Anesthetics – Block nerve impulses in a specific area, preventing pain signals from reaching the brain. Adjunct Drugs – Sedatives, opioids, and muscle relaxants enhance anesthesia effects and improve safety. In short, anesthesia is caused by pharmacological agents interacting with the nervous system, producing a controlled, reversible lack of sensation and consciousness for safe medical procedures.
