Local adverse effect of compressed-air aerosol inhalation for patients with pulmonary diseases and countermeasures

Abstract

Objective To explore the reasons of local adverse effect of compressed-air aerosol inhalation for patients with pulmonary diseases, and to put forward corresponding countermeasures. Methods By convenience sampling, 150 patients with respiratory diseases, treated by aerosol inhalation in Department of Respiratory Medicine in a Level III-Class A hospital in Tianjin, were selected, and were surveyed by a cross sectional questionnaire about their general data, knowledge of aerosol inhalation, the adverse effect the patients percepted during aerosol inhalation and their countermeasures. Results Within the 150 patients, clinical symptoms of 127 had been improved, with a total effective rate of 84.67%. Local adverse effect happened to 136 patients, accounting for 90.67%, including dryness in mouth, nose or throat, bitter taste, pharyngeal discomfort, cough, etc. Hoarseness happened to four patients. Only one patient discontinued the aerosol inhalation because of long lasting serious dryness in the upper respiratory tract. Comparison of incidence rate of local adverse effect in patients′ gender, educational background, monthly income, time of aerosol inhalation and mastery of relevant knowledge showed statistical significance (P 0.05) . Conclusions Main reasons leading to local adverse effect during aerosol inhalation are the patients′ lack of relevant knowledge and professional guidance. So during aerosol inhalation, nursing staff should take the initiative to guide the patients technologically, so that incidence rate of local adverse effect can be lowered, and patients′ treatment compliance improved.
