Anaesthesia - Anaesthesia symptom, treatment, causes
Anaesthesia means 'without feeling', anaesthesia is the loss of sensation when the nerve supply of any part of the body is damaged by injury or disease. Anaesthesia may also be induced deliberately by the use of drugs known as anaesthetics so that surgical, dental or other treatment may be performed without the patient being aware of pain.
Anesthesia is a condition of having the perception of pain and other sensations . Anaesthesia can be given in various ways and does not always make you unconscious . Regional anaesthesia means blocking the nerve supply to part of the body most of an arm. Anaesthesia can be induced and maintained by drugs injected into a vein and by the use of anaesthetic gases inhaled by the patient. Anesthesia diseases effect is a central nervous system.
Anesthesia a definite area of the skin surface. Its limits can be traced by the distribution of certain nerves . Anesthesia may occur in conjunction with hyperæsthesia and paræsthesia in other parts of the body. Many people have an anecdotal knowledge of the use of hypnosis for anaesthesia , but few appreciate how effective it is, and how easy it is to learn to create anaesthesia for oneself. Anesthesia is dministered for medical or surgical purposes, that induces partial or total loss of sensation and may be topical, local, regional, and general.
Anesthesia is depending on the method of administration and area of the body affected . The role of the Anaesthetist has changed in recent years. The most common regional anaesthetics are spinal and epidural anaesthetics. Anaesthetists are involved with all areas of critical care medicine as well as in the care of the surgical patient prior to the operation to optimise condition.
General Anaesthesia
General anaesthesia makes a patient unconscious so that sensations are not perceived. Drugs are administered by inhalation or by injection into a vein.
Local Anaesthesia
Local Anaesthesia is achievedby injecting around a nerve, or into the part to be treated, a drug that blocks transmission of sensations to the brain. It is possible to anaesthetise parts with lining membranes (such as the mouth, throat, and upper airways), through which local anaesthetic drugs can penetrate, for minor procedures. The pain of superficial lesions (such as mouth ulcers) may be relieved by local application of an ointment or spray containing an anaesthetic drug.
Spinal and epidural anaesthesia
Spinal and epidural anaesthesia< are variations of local anaesthesia in which anaesthetic drugs are injected underneath (spinal) or outside (epidural) the membrane called the dura mater that surrounds the spinal cord. Sensation on both sides of the body is blocked in nerves below the level of the injection.
