Pharmacological action of

The main active principle of pollen allergens is the protein-polysaccharide complex, allowing you to diagnose a patient with staging skin samples hypersensitivity to this type of pollen of plants and use it for immunotherapy of hay fever.

Indications

specific diagnosis and treatment of hay fever, atopic bronchial asthma, caused by hypersensitivity to pollen cyclicena foolish.

Indications for diagnosis are the clinical manifestations of the disease and history.

Indications for specific immunotherapy are determined by the allergist on the basis of history, clinical manifestations of the disease, results of skin testing, taking into account contraindications.

Use during pregnancy and lactation

Immunotherapy is contraindicated in pregnancy and lactation.

Special instructions

In case of doubtful results of skin tests, they can be repeated 2 days after the local reaction to previous tests subsided. In case of positive results, it is allowed to repeat skin tests with pollen allergens no more than once a month.

Particularly sensitive patients may experience a systemic allergic reaction and anaphylactic shock. In this regard, in the office where specific diagnostics and specific immunotherapy of patients are carried out, pharmacological preparations and tools for emergency care should be located.

Assistance in general reactions and anaphylactic shock.

Following administration of an allergen, symptoms of clinical manifestations of hypersensitivity to the allergen may develop. With parenteral administration of an allergen, an immediate type of reaction may develop, including anaphylaxis, which manifests itself in the form of urticaria and vascular edema, laryngeal edema, shortness of breath and suffocation. These symptoms often occur after a sensation of generalized itching, burning sensation, hyperemia of the skin, as well as a feeling of fear of death.

As a result of anaphylactic shock, persistent bronchospasm, asphyxiation due to edema of the upper respiratory tract, and collapse may develop.

In this case, urgent treatment is required.

Prehospital care for anaphylactic shock.

1. Immediately stop the administration of the allergen that caused the reaction, lay the patient on a couch (head below the legs), turn the head to the side, extend the lower jaw, and remove any dentures.

2. Put a tourniquet in place above the introduction of the allergen, if possible.

3. Chop the injection site with 0.3-0.5 ml of adrenaline solution (dilute 1 ml of 0.1% adrenaline solution in 3-5 ml of sodium chloride injection solution 0.9%).

4. Apply an ice pack to the injection site.

5. Introduce 0.3-0.5 ml of 0.1% adrenaline solution (for children 0.05-0.1 ml / year of life) in / m or in / in with an interval of 5-10 minutes. The multiplicity and dose of adrenaline administered depends on the severity of the shock and blood pressure indicators. The total dose of adrenaline should not exceed 1 ml of a 0.1% solution. Repeated administration of small doses of adrenaline is more effective than a single administration of a large dose.

6. Provide fresh air or oxygen. In case of violation of the rhythm of breathing or its difficulty to carry out artificial lung ventilation (mechanical ventilation).

7. Urgently call a doctor, at the same time, a resuscitation team is called up.

Hospital care for anaphylactic shock.

1. In an extremely serious condition of the patient and with severe hemodynamic disturbances, 5 ml of 0.01% adrenaline solution are injected slowly in / in, and the effect is stopped. Children 0.1 ml / kg 0.01% solution slowly over several minutes.

2. If blood pressure does not stabilize, immediately start intravenous drip of norepinephrine (phenylephrine, dopamine) 0.2% 1.0-2.0 ml per 500 ml of 5% glucose solution for infusion or sodium chloride injection solution 0.9% .

3. Intravenously inject glucocorticosteroids: prednisone - 60-180 mg (children 5 mg / kg), dexamethasone - 8-20 mg (children 0.3-0.6 mg / kg), hydrocortisone - 200-400 mg (children 4-8 mg / kg). According to the state, the administration of hormones is repeated and continued for at least 4-6 days to prevent allergic reactions of an immunocomplex or delayed type.

4. Only with the stabilization of blood pressure, intramuscularly introduce 2.0 ml of a 2% solution of chloropyramine (children 0.1-0.15 ml / year of life) or 0.1% clemastine.

5. Symptomatic therapy according to indications. With bronchospasm, 10.0 ml of a 2.4% solution of aminophylline in a solution of sodium chloride for injection 0.9% (for children 1 ml / year of life) is injected intravenously. If necessary, cardiac glycosides, respiratory analeptics are introduced.

6. If necessary, the accumulated secretion and vomit are sucked out of the airways, and oxygen therapy is started.

7. Patients receiving beta-blockers are shown additional administration of salbutamol and / or glucagon in / in 1 ml.

8. In acute laryngeal edema, intubation or tracheotomy is indicated.

All patients with anaphylactic shock are subject to mandatory hospitalization for a period of at least 10 days in order to continue monitoring and treatment, as 2-5% of patients who underwent anaphylactic shock have late allergic reactions.

Doses of injected drugs and the tactics of the doctor are determined by the clinical picture, but in all cases it is necessary, first of all, the introduction of adrenaline, glucocorticosteroid drugs. The introduction of phenothiazine and calcium preparations is contraindicated.

Prior to the arrival of the resuscitation team, it is necessary to provide medical care and constant monitoring of hemodynamic parameters and the state of the function of external respiration (HFD).

Dosage and administration of

I. Specific diagnosis.

The drug is used for staging skin samples (scarification, prik-test and intradermal). Specific diagnostics, as a rule, are carried out simultaneously with other pollen allergens. During one procedure, it is allowed to conduct up to 15 samples with pollen allergens of various kinds.

Skin tests are placed on the inner surface of the forearm or, if necessary, on the skin of the back.

Along with the allergen, skin tests are performed with a test control liquid and with a 0.01% histamine solution, which is prepared by diluting a 0.1% histamine dihydrochloride solution (1 part) with sodium chloride solution for injection 0.9% (9 parts). The diluted histamine solution is suitable for 6 hours from the date of preparation.

The metal cap of the vial (with allergens or test control fluid) is wiped with alcohol. The central cap cap is removed with sterile forceps, and the rubber stopper pretreated with 70% ethanol is punctured with a sterile needle.

The skin of the inner surface of the forearm is wiped with 70% ethyl alcohol and allowed to dry. A drop of the tested allergen, a drop of the test control liquid and a drop of 0.01% histamine solution at a distance of (30 Ѡ10) mm from each other are applied to the disinfected skin with a sterile syringe. An allergen drawn into a syringe cannot be poured back into the vial.

When staging scarification skin samples, two parallel scratches 5 mm long are applied through the applied drops with a sterile scarification needle.

When setting prik-tests through the applied drops with a sterile injection needle, a skin injection is carried out to a depth of not more than 1-1.5 mm.

For severe skin reactions, a safe initial treatment dose is selected, for which the allergometric titration method is used.

Intradermal samples are placed in cases where there are discrepancies in the data of clinical diagnostic methods and scarification samples.

Intradermal tests are carried out on an internal surface of a forearm. The skin is pulled down with the movement of the finger, the needle is inserted at an angle of 15 Рto the surface of the skin, it is necessary to ensure that the hole of the needle is completely hidden in the epidermis, the needle should be thin with a short tip.

Sterile, individual for each allergen, labeled syringes with a scale of 0.02 ml, 0.02 ml of allergen and test control liquid are injected strictly intracutaneously, a sample with 0.01% histamine is placed using a scarification method.

Assessment of diagnostic skin tests.

The local skin reaction when staging scarification skin tests, prik-tests is taken into account after 15-20 minutes, and intradermal samples after 20 minutes in the absence of reaction to the test control fluid and in the presence of a positive test for histamine.

flowering of trees and grasses. The period of use of

allergen after its dilution is 1 month.

After each allergen injection, the patient

is observed in the office for 60 minutes. The

doctor notes the skin reaction at the injection site of the

allergen and the general condition of the patient.

Contraindication for increasing the dose is

local reaction in the form of an infiltrate of

size more than 25 mm, the general reaction of the body, exacerbation of

underlying disease. In these cases, the dose of

is reduced, the intervals between
