Abstract:
OBJECTIVETo study the changes of pulmonary function in children with right lung middle lobe syndrome before and after treatment.
METHODSThirty children with right lung middle lobe syndrome were classified into two age groups: < or =4 years old and >4 years old. Pulmonary function was tested by the 2600-type and the MIR-type pulmonary function spirometry in the < or =4 years and the >4 years age groups, respectively before and after treatment. Terminal flows/peak expiratory flow (25/PF) and the percentage of tidal volume to peak tidal expiratory flow (% V-PF) were measured in the <4 years age group. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF) were measured in the >4 years age group.
RESULTSThe values of 25/PF and %V-PF in the < or =4 years age group were 0.42+/-0.08 and 0.28+/-0.03, respectively before treatment. The values were improved after treatment (0.58+/-0.12 and 0.39+/-0.06 respectively) (P<0.05). The values of FVC, FEV1 and PEF were 1.75+/-0.32, 1.36+/-0.52 and 2.56+/-0.78, respectively in the >4 years age group before treatment. The values were also improved after treatment (2.37+/-0.78, 2.08+/-0.65 and 3.68+/-0.80 respectively) (P<0.05).
CONCLUSIONSThere are significant differences in the pulmonary function before and after treatment in children with right lung middle lobe syndrome. The pulmonary function can return to normal after treatment.
