Allergic response produce histamines. These histamines will act on different areas of the body (eyes, throat, nose, gastrointestinal tract, skin or lungs) to produce symptoms of an allergic reaction. The allergic response is not limited to a certain amount of exposure. If the body is exposed to the allergen multiple times the immune system will react every time the allergen is present. The reason why people get allergies is not known. The allergens are not passed down through generations. It is believed if parents have allergies the child is more likely to be allergic to the same allergens. Some common symptoms include
Allergic reactions to anaesthesia Allergic reactions to anaesthesia The incidence of life-threatening hypersensitivity reactions occurring during surgery and anaesthesia is around one in 10,000 procedures. Serious allergic reactions to anesthetic medications are rare and a usually attributable to factors other than the anesthetic. Neuromuscular blocking agents, natural rubber latex, and antibiotics are the most common causes of serious allergic reactions during surgery. The mortality rate from these reactions ranges between 3-9%. Successful immediate treatment requires prompt recognition by the attending anaesthetist, or in the US, the attending anesthesiologist or nurse anesthetist. Anaesthetists are trained to recognise if an allergic reaction is occurring. The identification
