Abstract:
Introduction: Conventional Chest Physiotherapy (CCPT)
remains the mainstay of treatment for sputum mobilization
in patients with productive cough such as bronchiectasis
and “Chronic Obstructive Airway Disease” (COPD). However
CCPT is time consuming requires the assistance of a
physiotherapist and limits the independence of the patient.
Mechanical percussors which are electrical devices used to
provide percussion to the external chest wall might provide
autonomy and greater compliance. We compared safety and
efficacy of a mechanical chest percusser devised by
Formedic Technology with conventional chest percussion.
Methods: Twenty patients (mean age 64years) were
randomly assigned to receive either CCPT or mechanical
percussor on the first day and crossed over by “Latin square
randomisation” to alternative treatment for 6 consecutive
days and the amount of sputum expectorated was compared
by dry and wet weight. Adverse events and willingness to
use was assessed by a home diary and a questionnaire.
Results: There were 13 males and 7 females, eight
diagnosed as bronchiectasis and 12 COPD. The mean dry
weight of sputum induced by CCPT (0.54g + 0.32) was
significantly more compared with MP (0.40g + 0.11); p-value
= 0.002. The mean wet weight of sputum with CCPT (10.71g
+ 8.70) was also significantly more compared with MP (5.99g
+ 4.5); p-value < 0.001. There were no significant difference
in adverse events and majority of patients were willing to
use the device by themselves.
Conclusion: The mechanical percussor although produces
less sputum is well tolerated and can be a useful adjunct to
CCPT
