Adverse Reactions of Nebulization Treatment
Nebulized treatment is a way of dosing, which the medicinal solution is sprayed out in aerosol form and inhaled to the respiratory tract. It has the advantages of direct reach into lungs, high local concentration, quick onset, and less systemic reactions. However, nebulization treatment is not absolutely safe, it may cause some adverse reactions if inhaled improperly. When we encounter these problems, how should we deal with it?
1.What are the common adverse reactions of nebulization treatment?
Children don’t know the correct inhalation technique, If they inhale too vigorously or too fast, they will take in a large amount of aerosol to enter the bronchi and alveoli in a short time, aggravate bronchospasm, cause frequent coughing and wheezing.
How to deal with it: When taking nebulization treatment, you should strictly control the amount of nebulizing spray to avoid over-dose. Master the speed of nebulization, and avoid nebulizing too fast or too violent. Cough can be significantly reduced after intermittent inhalation.
- Acute Pulmonary Edema
The occurrence of acute pulmonary edema is mainly related to the large amount of aerosol inhalation and long duration. A large number of droplets continue to enter the alveoli, cause alveolar atrophy and lead to acute pulmonary edema. The patient will have a series of symptoms such as frequent coughing, a large amount of foamy sputum, and difficulty breathing.
How to deal with it: Master the amount of nebulization medicine to prevent over-dose. Especially avoid continuous nebulizing in large doses.
- Tracheal obstruction
Tracheal obstruction mostly occurs in infants and young children. Infants and young children have weak cough reflex, and often have sputum that is not easy to cough up, results in sticky sputum retention in the bronchus, which is especially easy to cause obstruction of the slender bronchus of young children.
How to deal with it: During the treatment period, the patient should take a comfortable position. If the sputum is diluted and irritates the child to cough after nebulization treatment, turn over and pat their back in time to assist in sputum excretion and keep the airway unobstructed.
2.What are the factors related to the adverse reactions of nebulization treatment?
First of all, a large amount of aerosol entering the trachea may cause tracheal spasm. And if child has high airway response, symptoms may worsen after improper inhalation method. The high concentration of medication solution irritates the throat, and repeated coughing and forcefulness leads to damage to mucous membrane of the throat. Last but not least, Individual differences may also cause adverse reactions.
3.How to handle baby and children nebulizing time?
If children are crying hard during treatment, it’s easy to cause vomit to enter the respiratory tract and suffocate. Prolong nebulizing time is easy to cause excessive humidification. Especially for infants less than 3 months and comatose children, excessive humidification can lead to excessive dilution and increase of sputum, causing airway obstruction.
Therefore, nebulization treatment should be done on an empty stomach and 1 hour after a meal. The appropriate time for each inhalation is 15-20 min each time. Children with a lot of sputum were given back sputum suction before and after nebulization treatment.
Note: The occurrence of adverse reactions may be related to direct action of medicine or factors such as hyperventilation, etc., need to be screened.
