Reasons for poor initial treatment effect At the beginning of treatment, there are very few patients with poor or slow onset, which is often related to improper inhalation methods, with the help of dual-use fog canisters, slowly and deeply inhaled to deliver the drug to the lesion site. For children with adenoid hypertrophy <3.5 years old with mask-type infant nebulizer inhalation, note that the mouth must be closed with nasal inhalation (or cover the mouth with paper or plastic wrap), note that the mask must be tightly covered, the green valve must be incited with breathing in order to effectively inhale. Children <3.5 years old with allergic rhinitis asthma syndrome should also try to inhale through the nose, while children with simple asthma can inhale through the mouth. Note: When inhaling medication via the nose, it should be inhaled when the nasal cavity is ventilated, and the nasal cavity should be cleaned with physiological seawater nasal rinse 15 minutes before inhalation, especially when there is thick nasal mucus or mucus, the nasal cavity must be rinsed with physiological seawater nasal rinse to rinse out the nasal mucus, otherwise the inhaled medication will easily stick to the nasal mucus and obviously affect the medication to contact the mucosa and lead to poor efficacy. An important reason why the disease is prone to relapse is that as the disease improves, the inhalation method of the patient or child becomes irregular, from slow and deep inhalation to hurried and hasty inhalation. Inadequate inhalation of medications and insufficient inhalation doses, etc. are the most common and important causes of recurrence of asthma, rhinitis or adenoid hypertrophy. Inhaled hormones have few side effects because they are inhaled in microgram quantities and are absorbed systemically with little local treatment. Inhaled budesonide has not been found to inhibit adrenocortical function and hypothalamic-pituitary-adrenocortical axis at the recommended therapeutic doses and when used correctly, nor has it been found to have side effects such as edematous obesity, osteoporosis, hirsutism, etc. According to a large sample of clinical observations of inhaled budesonide in the UK over a 2-year period, the results confirmed that it does not affect the growth and height of children. Inhalation of hormones should be noted: 1. Timely rinsing of the mouth after inhalation via the mouth (should be inhaled a snap rinse once) and spitting out the mouthwash is a key measure to avoid systemic adverse reactions to hormones inhaled via the mouth. A small number of patients may experience hoarseness and should rinse their mouths using the pharyngeal gargle method. Very few children may have occasional thrush, which is also related to not rinsing the mouth in time after inhalation. For children with allergic rhinitis and adenoid hypertrophy treated by inhalation, there may be drug deposition in the throat when inhaling slowly and deeply, so it is best to rinse the mouth promptly after inhalation and clean the nasal vestibule (i.e., at the nostrils) with a cotton swab dipped in physiological saline. 3, for infants and children under 3.5 years old with mask-type infant nebulizer cans, you should wash your face and rinse your mouth in time after inhalation, and it is also best to use a cotton swab dipped in saline to clean the nostrils after inhalation.
