Respiratory physical therapy techniques recommended for patients with cystic fibrosis treated in specialized centers.

ABSTRACT

BACKGROUND: Respiratory therapy is a part of the treatment of patients with cystic fibrosis (CF). However, there is no information about the main factors influencing the recommendation of the use of different techniques or devices by physical therapists from different specialized centers. OBJECTIVE: To determine the respiratory therapy techniques recommended for the treatment of patients with CF seen in specialized treatment centers in Brazil. METHODS: This is a descriptive study including a sample of Brazilian CF specialized treatment centers. Data on demographics, spirometric variables, and recommended respiratory therapy treatment techniques were collected. RESULTS: Twelve specialized treatment centers with a total of 974 patients were included (13.5±11.3 years old and FEV1 (%) 75.7±27.9). The most recommended techniques were huffing (61.1% of patients), high frequency oral oscillation (HFOO) (52.0%), and positive expiratory pressure (PEP) (45.3%). Most often, recommendation was to perform treatment once (54.8% of patients) or twice (34%) a day. There was great variability in the recommendation among the different states. When data were separated by age, there was a predominance of performing conventional and manual techniques in infants and preschool children. There were no significant variations according to pulmonary function. Based on the literature, techniques based on volume, huffing, and PEP were most prevalently performed in international centers. CONCLUSION: The most recommended treatment techniques for patients with CF in Brazil are huffing, HFOO, and PEP, followed by volume-based techniques. There were geographical variations in the preferred treatment techniques, as well as based on patient age, but not based on the level of pulmonary function.
