NONİNVAZİV MEKANİK VENTİLASYON DESTEĞİ OLAN VE OLMAYAN AKUT SOLUNUM YETMEZLİĞİNDE FONKSİYONEL BAĞIMSIZLIK VE KAS KUVVETİ

Amaç: Akut solunum yetmezliği (ASY) sürecinde kas zayıflığı gelişimi sıktır. Bu çalışmanda yoğun bakımda ASY nedeni ile tek başına standart medikal tedavi (SMT) ve SMT’ye ek olarak noninvaziv mekanik ventilasyon (NIV) uygulanan olgularda kas kuvveti ve fonksiyonel bağımsızlığı karşılaştırılmak amaçlandı. Yöntem: Çalışmaya ASY ile izlenen 32 olgu (19 NIV ve 13 SMT) dahil edildi. Olguların özellikleri kaydedildi. Periferal kas kuvveti için Medical Research Council Skalası (MRC) kullanıldı ve el kavrama kuvveti ölçüldü. Fonksiyonel bağımsızlık düzeyi Barthel İndeksi (Bİ) ile değerlendirildi. Sonuçlar: NIV grubunda proksimal kas kuvveti (omuz abduktorleri) distal ekstremite kas kuvvetinden (el bileği ekstansorleri) anlamlı olarak daha düşüktü (p=0,030). Her iki grupta, proksimal alt ekstremite kas kuvveti (kalça fleksiyonu), distal ekstremite kas kuvveti (ayak bileği)’nden anlamlı olarak daha azdı (p=0,002). NIV grubunun Bİ toplam puanı SMT grubundan anlamlı olarak daha düşüktü (p=0,016). Bİ puanı, MRC toplam puanı (r=0,633) ve el kavrama kuvveti (r=0,629) ile ilişkiliydi (p<0,05). Tartışma: ASY nedeni ile NIV uygulanan hastalarda fonksiyonel bağımsızlık ve distal kas kuvveti ile karşılaştırıldığında proksimal kas kuvveti olumsuz yönde etkilenmektedir. Yoğun bakımda rehabilitasyon uygulamalarında zayıflık veya fonksiyonel kısıtlılığın hastaların uygun fonksiyon görmesini engelleyebileceği göz önünde bulundurulmalıdır.

FUNCTIONAL INDEPENDENCE AND MUSCLE STRENGTH IN ACUTE RESPIRATORY FAILURE WITH AND WITHOUT NON-INVASIVE MECHANICAL VENTILATORY SUPPORT

Purpose: Development of muscle weakness is common in the course of acute respiratory failure (ARF). This study aimed to compare muscle strength and physical function in subjects with ARF undergoing noninvasive mechanical ventilation (NIV) added to standard medical treatment (SMT) and SMT only in the intensive care unit. Methods: Thirty-two subjects with ARF (19 NIV and 13 SMT) were included. Subject characteristics were recorded. Peripheral muscle strength was measured using the Medical Research Council Scale (MRC) and handgrip strength. Functional independence was evaluated using the Barthel Index (BI). Results: In the NIV group, proximal muscle strength (shoulder abduction) was significantly lower than distal limb strength (wrist extension) (p=0.030). In both groups, proximal lower limb strength (hip flexion) was also significantly lower than distal limb strength (ankle dorsiflexion) (p=0.002). The BI total score was significantly lower in the NIV group than that of the SMT group (p=0.016). The BI score was significantly related to the MRC sum score (r=0.633) and handgrip strength (r=0.629, p<0.05). Conclusion: Functional independence and proximal muscle strength compared to distal adversely affected in patients undergoing NIV for ARF. Weakness or functional limitations may prevent patients from functioning adequately in rehabilitation practices in intensive care.
