Evaluation of cough strength in bronchiectasis

Abstract

Purpose: This study aimed to evaluate the cough strength in bronchiectasis patients. We also planned to examine the relationship between cough strength, exercise capacity and quality of life. Materials and methods: The study included 24 bronchiectasis patients (bronchiectasis group) and 25 healthy individuals (healthy group). Exercise capacity was evaluated with the six minute walk test (6MWT). Cough strength (Peak cough flow (PCF)) was assessed using Mini-WrightTM peak flow meter (PFM) with a mouthpiece. The quality of life was evaluated with Leicester Cough Questionnaire (LCQ). Results: A significant difference was found between the groups in terms of PCF, 6MWT, LCQ total score and subdimension scores showed significant differences in favor of the healthy group (p<0.05). A positive high correlation was observed between PCF and the following variables: 6MWT and LCQ total score (r=0.780, p<0.000 and r=0.885, p<0.000, respectively). Conclusion: This study found that cough strength was worse in bronchiectasis patients compared with healthy individuals. In addition, cough strength could negatively affect exercise capacity and quality of life. Therefore, cough strength should be added to the evaluation parameters.

Bronşektazide öksürme kuvvetinin değerlendirilmesi

Abstract

Amaç: Bu çalışmada bronşektazi hastalarında öksürme kuvvetinin değerlendirilmesi amaçlandı. Ayrıca öksürme kuvveti ile egzersiz kapasitesi ve yaşam kalitesi arasındaki ilişkiyi incelemeyi planladık. Gereç ve yöntem: Çalışmaya 24 bronşektazi hastası (bronşektazi grubu) ve 25 sağlıklı birey (sağlıklı grup) dahil edildi. Egzersiz kapasitesi 6 dakika yürüme testi (6DYT) ile değerlendirildi. Öksürme kuvveti (Tepe öksürük akımı (TÖA)), Mini-WrightTM Pef cough metre (PCM) kullanılarak değerlendirildi. Yaşam kalitesi, Leicester Öksürük anketi (LÖA) ile değerlendirildi. Bulgular: Gruplar karşılaştırıldığında TÖA, 6DYT, LÖA total puan ve alt boyutları arasında sağlıklı grup lehine anlamlı fark görüldü (p<0,05). TÖA ile 6DYT ve LÖA total puan arasında pozitif yönde yüksek düzeyde anlamlı ilişki saptandı (sırasıyla r=0,780, p<0,000 ve r=0,885, p<0,000). Sonuç: Bronşektazi hastalarının öksürme kuvvetinin sağlıklı bireylere göre daha kötü olduğu görüldü. Ayrıca, öksürme kuvveti egzersiz kapasitesini ve yaşam kalitesini olumsuz etkilediği için değerlendirme parametrelerine öksürük kuvveti eklenmelidir.
