[Pulmonary function of children with right lung middle lobe syndrome].

Abstract

OBJECTIVE:

To study the changes of pulmonary function in children with right lung middle lobe syndrome before and after treatment.

METHODS:

Thirty 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.

RESULTS:

The 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).

CONCLUSIONS:

There 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.
