Characterizing mucociliary clearance in young children with cystic fibrosis

EFFECT OF HIGH-FREQUENCY CHEST WALL OSCILLATION ON CLINICAL INDICES OF COMMUNITY-ACQUIRED PNEUMONIA IN CHILDREN

OBJECTIVE

The aim: To study the effect of high-frequency chest wall oscillation (HFCWO) on clinical indices of community-acquired pneumonia (CAP) in children.

PATIENTS AND METHODS

Materials and methods: The main clinical symptoms were assessed in 107 children (girls - 45.79% and boys - 54.21%) aged 6 to 17 years with acute and uncomplicated course of CAP of moderate severity. The main group (MG) consisted of 55 children who were prescribed basic therapy (BT) in combination with HFCWO procedures. The control group (CG) comprised 52 children who received BT exclusively.

RESULTS

Results: In the children of MG, the intensity of cough decreased to 0.28 ± 0.06 points compared with children of CG - 0.5 ± 0.07 points (p <0.05) on the 10th day of treatment. A positive dynamics of CAP in the form of the amount of sputum reduction was revealed in the MG children up to 0.06 ± 0.03 points compared with the CG children - 0.42 ± 0.07 (p <0.05). On the 10th day of therapy the MG children with CAP had decrease in the number of râles in the lungs up to 0.08 ± 0.04 points compared with those of CG - 0.4 ± 0.07 points (p <0.05).

CONCLUSION

Conclusions: High efficacy of HFCWO method in complex treatment of CAP in children is confirmed by the dynamics of the main clinical symptoms, such as reduction of intensity and productivity of cough as well as absence shortness of breath and moist râles in the lungs. The data obtained indicate recovery of mucociliary clearance (MCC) functions and the bronchopulmonary system as a whole.
