There are several types of reactions after insect bites, sometimes with similar clinical manifestations, so it is good to know poderlas differentiate apply appropriate treatment to each type of reaction.
The reactions can be divided into three groups:
Not immune.
Immunologic.
No defined mechanism.
January. Immunological reactions:
They are tissue responses to venom components with a high power drug and enzyme. Usually these reactions occur between 24 and 48 hours after the bite. They are presented with a swelling around the site of the bite of an internal diameter of 10 cm., Pain more or less strong depending on the site of the bite (higher in the limbs). Reactions can be local or systemic mild.
Treatment is symptomatic with measures such as cold compresses, antihistamines, and anti-inflammatory.
2. Immunological reactions:
Allergies to Insect Stings
- Presents a strong local reactions. It swells around the site of the bite with a diameter greater than 10 cms. and stays for more than 48 hours in children the inflammation can affect two adjacent joints. In these patients showed presence of antibodies against some components of the venom such as hyaluronidase, and phosphatase.
The treatment is with antihistamines and anti-inflammatory, but it must be conducted to see the intensity of sensitization if necessary immunotherapy treatment.
- Known as serum sickness. Immune reaction also does not appear immediately after the bite, but after a few days (between 2 and 10) and presents with fever, generalized inflammation of the skin, joint pains, and swollen glands. The symptoms resolve without sequelae within 1 to 2 weeks.
The treatment is with steroids (cortisone), do not require immunotherapy.
- Anaphylaxis. Anaphylactic reactions various systems and organs and jeopardize the patient’s life. The first symptoms are usually skin, such as hives affecting the whole body, general itching may also occur and swelling of the skin. If the reaction is more intense pictures associated with general anxiety, fatigue, breathing (dyspnea), chest tightness, coughing, vomiting, diarrhea and abdominal cramps, urinary incontinence (including fecal), uterine cramps, arrhythmias and circulatory collapse or pulmonary edema.
In some cases, there are always the same clinical picture of anaphylaxis due to a cut back in others anaphylactic table is becoming increasingly severe and serious.
In these cases, treatment should be put to insect venom immunotherapy in question (bee or wasp) and carry an adrenaline kit treatment on self-injection syringe Tortor + + Antihistamine. You must have your instructions for self-inoculated the adrenaline in case of accidental bite.
3. No clear mechanism:
Renal, nerve inflammation, meningitis, and blood clotting disorders (purple).
The treatment is specific in each case and does not require Immunotherapy
How to Avoid the bee and wasp stings
Both bees and wasps sting only in defense of themselves or their nests. Most bites occur between the months of May and September July and August being the months with highest incidence of stings due to high temperatures that make a great activity to these insects.
The honeybees are attracted by the fragrance of flowers, bright colors and the surface of calm water with this in mind to prevent accidents should be taken not to wear bright colors or strong perfumes during the period of greatest activity.
These wasps feed on juices, sap, nectar and, in general, liquid sugar, some larval wasps feed on other insects for which the parent uses its venom to paralyze the future food source for the larvae. To inoculate the wasp venom the sting can preserved and repeatedly biting, which does not happen with the stingless bees has as its lateral recesses, by way of hooks, are anchored to the tissue of the victim, losing along with part of the digestive system , so the bee can only sting once and die.
In case of bee or wasp sting that have not been seen it would appear that the latter was to remain anchored the sting to the skin must be careful when removing it because it may inadvertently press the venom sac and inoculated all of its contents, in any case, when the stinger is stuck in the tissue together with part of the intestine of the bee that has escaped the venom gland will continue to contract periodically to inoculate all, so it is important to remove the stinger as soon as possible.
When a wasp stings it releases a pheromone that encourages others in the colony to be bitten by it is advisable, if stung, move away as soon as possible to the accident area to prevent a massive attack.
Recommendations
Do not go near beehives or wasp nests, if you accidentally close, retire with slow movements.
If a bee or wasp lands on any part of your anatomy do not try to kill or frighten it, stay still or made only slow movements until they go away.
During hot weather, if you drink a sugary liquid, check that there are no bees or wasps at the edges of the bowl.
If you leave clothes on the floor shake before wearing, as there may be a wasp in its folds.
Avoid walking in gardens in bloom, fields of clover or any area with abundant flowers.
During the period of activity (May to September) wear inconspicuous color and do not use perfume or hairspray when you leave the field.
Do not prune trees or mow lawns or hedges during the period of activity.
Collisions with these insect stings can cause so avoid running or riding, by bicycle or motorbike in areas where an abundance of flowers. A convertible car with the roof down is especially dangerous.
Within enclosures maintain a net to catch any flying insect that enters, it is also useful to have an insecticide to kill them (in the glove compartment can be very useful).
Warn children not to throw stones or branches to the nests of insects
