Anaesthesia
In Greek, ‘Anaesthesia’ means ‘loss of sensation’. Anaesthesia is the condition where the physical sensations are taken away, temporarily without the person becoming unconscious. The person remains conscious throughout the period the anaesthetic has been injected - in most cases. Anaesthesia is used for medical purposes. Anaesthesia is required to relax the patient, both physically and mentally, so that the doctors can carry out their work without getting interrupted. The other reason is to prevent pain and discomfort. When a surgery or a medical procedure is needed to be done, the patient is subjected to anaesthesia. There are various ways on how an anaesthetic drug can be given – rubbing of an ointment, a nasal spray, a droplet, an injection, orally, inhalation of a gas etc.
How does Anaesthetics work?
Anaesthesia works by blocking nerve transmission from going to the pain centres in the central nervous system via nerves. Nerves are tiny bundles of fibres. This happens when anaesthetics bind to and inhibit the function of an ion channel (Sodium Channel) in the cell membrane of nerve cells.
Types of Anaesthesia
There are mainly three types of anaesthesia. Those three are:-
1) Local Anaesthesia
A local anaesthetic numbs a small part of your body. It is used when the nerves can easily be reached by drops, sprays, ointments or injections. The consciousness is not lost, but the patient will be free from pain or any other sensation that the area of administration might cause. Local anaesthesia is used for minor medical procedures, like stitching of a cut or for treating a minor wound. Local anaesthesia lasts from about a few minutes to a few hours.
2) Regional Anaesthesia
Regional anaesthesia can be used for operations on larger or deeper parts of the body. Local anaesthetic drugs are injected near to the bundles of nerves which carry signals from
