Study design (if review, criteria of inclusion for studies)
RCT
Participants
20 newly diagnosed infants with CF (mean age, 2.1 months; range, 1-4)
Interventions
standard postural drainage chest physiotherapy (SPT) or a modified physiotherapy regimen without head-down tilt (MPT). Parents kept a detailed symptom and treatment diary for the following 12 months.
Outcome measures
Serial chest radiographs, taken at diagnosis, 12 months, 2(1/2) years, and 5 years after diagnosis, were assessed using the Brasfield score. Pulmonary function tests were compared between groups after 5 years.
Main results
Of the 20 infants, 16 (80%) completed the review at 12 months, and 14 (70%) at 2(1/2) and 5 years. Patients receiving SPT had more days with upper respiratory tract symptoms than those on MPT (70 +/- 32.8 vs. 37 +/- 24.9 days; P = 0.04) and required longer courses of antibiotics (23 +/- 28.5 vs. 14 +/- 11.2 days; P = 0.05). Chest x-ray scores were similar at diagnosis but were worse at 2(1/2) years for those receiving SPT (P = 0.03). Forced vital capacity and forced expired volume in 1 sec (FEV(1)) at 5-6 years was lower for SPT than for MPT (P < 0.05).
Authors' conclusions
MPT was associated with fewer respiratory complications than SPT in infants with CF.
