Recently, our country has entered on both sides of the Changjiang River cold season, the north is snow, the south is always rainy. The number of patients with respiratory diseases in hospitals around the country has also increased dramatically.
Inhalation therapy of asthma refers to corticosteroids and beta 2 agonists, anticholinergic drugs and cromolyn sodium and other drugs made of aerosol particles or powder particles in an aerosol or dry powder method etc. to prevent and relieve the symptoms of respiratory inhalation. Inhalation therapy is superior to oral administration, intramuscular injection and intravenous administration. However, the correct method of drug absorption has a direct impact on clinical efficacy, so clinicians must teach patients and their families to master the correct inhalation method.
At present, there are still some problems in inhalation therapy: one is that the patients are not familiar with the inhalation technique. Inhalation therapy is different from oral therapy, it needs to use some of the inhalation skills. According to foreign reports on inhalation aerosol return data show that only 1/3-1/2 patients can master the inhalation of skills, so the families of patients with asthma patients with inhalation therapy after drug use is very important. The second is not long-term adherence. Inhalation therapy is rapid and the symptoms can be relieved soon, so many patients believe that the effect has been achieved and stop using. In fact, the short-term use of regular drug treatment after the patient's lung function and potential airway inflammation has not been completely alleviated, the excessive reduction or even interruption duration, often will be delayed for a long time, and the emergence of recurrent symptoms. Therefore, the correct approach is to improve the condition, every 3 months to conduct a comprehensive assessment, the condition is effectively controlled, can gradually reduce, rather than stopping drug.
In general, moderate and severe asthma need to adhere to medication 1-3. For the elderly, children with asthma, the need for personalized, differentiated treatment. Special attention is needed to closely observe the condition in patients with asthma after the withdrawal, closely observe whether there are signs of recurrence after discontinuation, including understanding and recognition such as nasal congestion, runny nose, cough and asthma in early signs, found early signs of mild asthma attack immediately restore inhalation treatment, prevent the progression of the disease.
Inhalation techniques for quantitative aerosol (MDI)
The commonly used MDI preparation are available domestic bronchodilators (such as salbutamol), anticholinergic bronchodilator type (such as ipratropium bromide) and glucocorticoids (e.g. beclomethasone dipropionate). When the device is used to open the lid of drugs, drug tank shaking several times, with MDI in the upright position, with a spout, pay attention to the teeth, tongue is not blocking the nozzle in the slow deep inhale while pressing with a finger, keep the breath for more than 10 seconds after the slow breath movement. There are difficulties for suction and suction medicine can not effectively maintain the breath movement synchronization, the elderly and children, can be installed on the nozzle in chuwuguan, mouth bite or nasal mask covering mouth and nose, press the aerosol, the medicine mist sprayed stored in the tank, let the patient breathe naturally about 30 seconds. Usually the first use of bronchodilators (salbutamol and / or ipratropium bromide), wait for 3-5 minutes, then inhaled corticosteroids, inhaled the same way, 2-3 times a day. Use chuwuguan + nasal mask inhalation in the treatment of patients, should gargle, face in inhalation therapy after removal of residual drug in the skin.
Dry powder inhaler (DPI) inhalation technique
At present, there are many kinds of DPI available in the domestic market, and the appearance of the device and the procedure are different because of different manufacturers. That is already in the inhalable drug device state, with the listener with nozzle for lip suction action, the intensity and magnitude of suction should not be too big; should avoid sucking force suck action (such as Straw drink), because the oral space narrowed sharply, inhaled drug powder may have gathered in adsorption the oral mucosa, and did not enter the airway, to reach the desired effect.
Atomization inhalation (NEB) technique
The utility model relates to a method for treating the medicine liquid in the gas phase to disperse into a mist particle (aerosol) by using the ultrasonic cavitation and the high speed air flow impact. Small droplets atomization treatment requirements (diameter of about 3 ~ 5 m) and uniform, so that after inhalation into the bronchioles and alveoli, play the corresponding role.
Atomization inhalation is especially suitable for children and the elderly, the breathing mode of patients requires less, can choose a variety of drugs, the type of disease is also more obvious than MDI and DPI.
Techniques for inhalation therapy include:
1 as far as possible in the sitting position of the atomization treatment, long-term bed bed, can take half lying position.
2 patients with hand-held nebulizer or wearing nasal mask, do slow deep breathing movements, make the drug fully reach the bronchi and lungs, then inhale breath 1-2 seconds, the better.
3 atomization treatment, if the patient feels tired, can be suspended for a short time after the inhalation, until the liquid absorption. General 10-15 minutes to 5ml liquid medicine atomization inhalation.
4 the use of nasal mask inhalation therapy, timely mouthwash, brush a face, in the surface of the skin to remove residual drug.
