Clinical and functional features of bronchial asthma in pregnancy

Abstract

Clinical course of bronchial asthma (BA) was followed-up during pregnancy (in I, II, and III trimesters). We observed 62.3 % of patients with mild BA, 29.8 % with moderate and 7.9 % with severe BA. Acute bronchial asthma was diagnosed in 68.4 % of the patients, of them 40.5 % were in the I trimester, 55.7 % were in the II trimester and 54.4 % were in the III trimester. During the follow-up period BA was stable in 43 % of the cases, improved in 14 % and worsened in 43 %. Complicated pregnancy course was diagnosed in 94.7 % of the patients. High frequency of perinatal complications was found. A complex assessment of lung function using spirography and zonal reography of the lungs allows early detection of the respiratory failure and timely diagnosis of BA impairment.
