An anaesthetic is a drug mixture that when administered, causes sensation loss. They are grouped into the following:
Your surgeon or anaesthetist will talk through the various options with you and recommend the best type, but it you will make the final decision about which anaesthesia you wish to receive. This document will provide details outlining the benefits and risks in order to help you in your decision, and let you make an informed choice. If you have questions that this document does not answer, it is recommended that you ask your surgeon, anaesthetist, or healthcare team.
These are usually injected through a drip (small tube) into a vein. Within about 30 seconds, most people are asleep. Although the injection may ache slightly at the time, the uncomfortable feeling will often be gone by the time you wake up.
It is also an option to administer anaesthetic as a gas. This will be through a face mask, and should also take effect in about 30 seconds.
During your operation, more of the same anaesthetic is administered either by the drip or by anaesthetic gases in order to keep you asleep. Sometimes the anaesthetist may also administer further medication to limit any sickness or pain afterwards.
When the operation is over, the anaesthetic wears off, which enables you to wake up.
It is possible to give different combinations of anaesthesia, so the operation can proceed with the smallest amount of discomfort to you. An example of this is a local anaesthetic being given to a patient before a general anaesthetic.
The simplest way to give a local anaesthesia is to inject it around the area which is going to have the procedure. It may burn or sting initially, but the area should go numb after a couple of seconds.
When it comes to nerve blocking, a combination of local anaesthetics and painkillers will be injected to the part of your body on which you be operated, near to the major nerves of this area.
This will temporarily numb the nerves to give you pain relief. A fine tube called a catheter is inserted near into the epidural space near the spinal cord. Most of your nerves pass through this space. Once the catheter is in place, a mixture of painkillers and local anaesthetics are injected into the epidural space, and your nerves should be numbed.
This technique is similar, but with a spinal anaesthesia you will only receive one injection. This is inserted into the bag of fluid surrounding the spinal cord.
For most patients all types of anaesthesia are safe. If you require a general anaesthetic, it may be necessary to undergo a couple of tests before the operation, to see how safe this will be. These tests will allow the healthcare team to choose what other options are available and if they need to carry anything out differently.
Death following an operation is nearly always because an individual’s body cannot cope with the surgery itself. This risk increases if you have ill health and require emergency surgery.
The anaesthetist may also recommend that you see your GP, to discuss improving your medical condition beforehand. These include angina, asthma, anaemia or high blood pressure.
Anaesthesia in its different forms can be used to provide a safe and effective way for you to undergo a operation, as well as giving you the necessary pain relief. An awareness of them will also help you to detect and treat any potential problems at an early stage. Complications can occur, although usually people do not have any issues and are satisfied with the anaesthetic. In order to make an informed decision about an anaesthetic, it is important that you are aware of these complications.
