Types of Anaesthesia

types-of-anaesthesia

There are several types of anaesthesia:

General anaesthesia produces a drug-induced unconscious state where the patient will not respond to any stimuli, including pain. It may be associated with changes in breathing and circulation.

Local anaesthesia involves the injection of local anaesthetic around the surgical area to eliminate pain stimuli and is usually used for minor surgery. It may be used alone or in combination with sedation or general anaesthesia.

Regional anaesthesia includes “nerve blocks” and “spinal blocks”. This is when local anaesthetic is injected in the vicinity of major nerve bundles that supply body areas such as the whole lower body, upper or lower limb or specific area like hand or ankle. This may be used alone or combined with sedation or general anaesthesia

Procedural sedation is used for procedures where general anaesthesia is not required. Different levels of sedation may be given depending on the requirement of procedure. It allows patients to tolerate procedures that may otherwise be uncomfortable or painful.

Conscious sedation is a medication-induced state that reduces the patient’s level of consciousness. A sedated patient does not feel pain but can respond to verbal commands or touch.
