Abstract

Aim: Coronavirus-2019 (Covid-19) primarily affects the respiratory system, and how it affects respiratory muscles and lung volume is still not fully understood. Our study aimed to assess the time-dependent changes that may occur in lungs and respiratory muscle sizes on chest computed tomography (CT) in adult coronavirus disease 2019 (COVID-19) patients.
Material and Methods: The clinical and radiological records of 101 adult patients who had at least two non-contrast chest CT images in stage 1 (0-4 days) and stage 6 (>28 days) were collected retrospectively. ImFusion Suite program were used to calculate lung volumes, and the cross-sectional areas of the pectoral and intercostal muscles were also calculated using with “ImageJ” program.
Results: One-hundred one patients (51 females, 50.49%) were included in the study. ANCOVA revealed a significant stage*side interaction effect regarding cross-sectional area (CSA) of intercostal muscles [(p=.010; η²p=.064)]. There was no significant difference between the two stages in terms of CSA of pectoralis major and minor muscles [(p=.314; η2p=.010), (p=.644; η²p=.002)] respectively and lung volume [(p=.340; η²p=.009)].
Conclusion: Covid-19 pneumonia causes an atrophy in respiratory muscles. However, it seems to have a nonsignificant effect on auxiliary respiratory muscles and lung volume. Further investigation of respiratory muscles and respiratory muscle training to reduce the risk of serious complications during viral infections are required.

Akciğer Hacmi ve Solunum Kasları Ağır Seyretmeyen Covid-19 Hastalarında Nasıl Etkilenir?

Abstract

Amaç: Coronavirus-2019 (Covid-19) öncelikle solunum sistemini etkiler ve solunum kaslarını ve akciğer hacmini nasıl etkilediği hala tam olarak anlaşılamamıştır. Çalışmamız erişkin koronavirüs hastalığı 2019 (COVID-19) hastalarında akciğer bilgisayarlı tomografisinde (BT) akciğerlerde ve solunum kası boyutlarında zamana bağlı olarak oluşabilecek değişiklikleri değerlendirmeyi amaçladı.
Materyal ve Metot: Evre 1 (0-4 gün) ve evre 6’da (>28 gün) en az iki kontrastsız göğüs BT görüntüsü olan 101 erişkin hastanın klinik ve radyolojik kayıtları geriye dönük olarak toplandı. Akciğer hacimlerini hesaplamak için ImFusion Suite programı kullanıldı ve pektoral ve interkostal kasların kesit alanları da “ImageJ” programı kullanılarak hesaplandı.
Bulgular: Yüz bir hasta (51 kadın, %50,49) çalışmaya dahil edildi. ANCOVA, interkostal kasların kesit alanına (KA) ilişkin önemli bir evre*yan etkileşim etkisi ortaya çıkardı [(p=.010; η²p=.064)]. Sırasıyla pektoralis major ve minor kaslarının KA’sında [(p=.314; η²p=.010), (p=.644; η²p=.002)] ve akciğer hacminde [(p=.340; η²p=.009)] iki evre arasında anlamlı bir fark bulunmadı.
Sonuç: Covid-19 pnömonisi solunum kaslarında atrofiye neden olur. Ancak yardımcı solunum kasları ve akciğer hacmi üzerinde önemsiz bir etkiye sahip olduğu görülmektedir. Viral enfeksiyonlar sırasında ciddi komplikasyon riskini azaltmak için solunum kaslarının daha fazla araştırılması ve solunum kas eğitimi gereklidir.
