1. What is the composition of anaesthesia?
In the earlier days, anaesthesia was composed of ether or chloroform, but nowadays it consists of nitrous oxide gas mixed with the derivatives of ether, such as isoflurane, sevoflurane and desflurane.
2. What are the types of anaesthesia?
The types of anaesthesia are
(1) General anaesthesia: Used for major operations like knee replacement
(2) Intravenous/monitored sedation: It makes you drowsy
(3) Regional anaesthesia: Numbs a particular part of the body but the patient is aware
(4) Local anaesthesia: Numbs a very small area and is used for procedures such as stitches or mole removal.
3. What are the risks associated with anesthesia?
Anaesthesia is a safe procedure, but a patient undergoing long hours of surgery or elderly patients are likely to develop confusion, heart attack, stroke and pneumonia after surgery.
4. What does anesthesia feel like?
Anaesthesia is like reversible coma, where you lose your ability to feel pain, memorise events and move around.
5. Why do people sleep after they are given anesthesia?
Medicines used in anaesthesia induce deep sleep so that patients cannot feel the pain of the surgical procedure.
