The term anaesthetic refers to drugs which prevent the pain during surgery. There are various drugs which are used in the modern anaesthetic process.
Anaesthetics can be divided into two categories: general anaesthetics and local anaesthetics. General anaesthetics cause a reversible loss of consciousness. Instead, local anaesthetics provoke a loss of sensation in a limited area of the human body.
Local anaesthetics include procaine, lidocaine, prilocaine, ropivacaine, cocaine, dibucaine and mepivacaine. These substances prevent the transmission of the nerve impulses without causing unconsciousness.
The most common general anaesthetics are desflurane isoflurane, sevoflurane and methoxyflurane. All these anaesthetics are volatile agents which evaporate into a vapour that provokes the general anaesthesia. However, there are other general anaesthetics which are used intravenously. These include barbiturates, benzodiazepines, propofol and ketamine.
As well as this, there are other anaesthetics which are used to relax muscles. These can be divided into depolarizing muscle relaxants and non-depolarizing muscle relaxants. The second category is furtherly divided into short-acting muscle relaxants, intermediate-acting muscle relaxant and long-acting muscle relaxants.
