Abstract

Background: Acute kidney injury (AKI) affects 5–30% of intensive care unit (ICU) patients and is associated with increased mortality (40– 90%), prolonged ICU stays, and higher healthcare costs. While the interplay between lung and kidney injury is increasingly recognized, the impact of AKI on weaning from mechanical ventilation (MV) remains underexplored. This study evaluates the effect of AKI on MV weaning outcomes in ICU patients. Methods: A retrospective cohort study was conducted in an Internal Medicine ICU (2010–2015). Patients intubated for respiratory failure (≥48 hours) were included, excluding those with chronic kidney disease, chronic lung disease, or heart failure. AKI was defined according to the KDIGO criteria based on serum creatinine levels (an increase of ≥0.3 mg/dL within 48 hours or ≥1.5-fold within 7 days). Due to the retrospective nature of the study, urine output data were not reliably available for all patients and therefore were not included in the AKI definition. AKI was assessed based on data obtained during the intensive care course and was considered to have developed during ICU hospitalization. A total of 100 patients with AKI and 100 without AKI were compared in terms of demographic characteristics, laboratory parameters (creatinine, albumin, hemoglobin, pH, PaO₂, PaCO₂), SOFA and APACHE II scores, sepsis status, and weaning outcomes. Statistical analyses included Student’s t-test, chi-square test, and multivariable logistic regression. The multivariable model included AKI status, age, APACHE II score, SOFA score, albumin level, and sepsis as covariates. Results: Overall weaning success was 28% (56/200), with 13% in the AKI group and 43% in the non-AKI group (p 0.05). Conclusion: AKI significantly impairs weaning from mechanical ventilation in ICU patients. Even after adjustment for disease severity, AKI remains an independent predictor of weaning failure. Early recognition of AKI may improve clinical management and facilitate successful weaning.

Özet

Arka plan: Akut böbrek hasarı (AKI), yoğun bakım ünitesindeki (YBÜ) hastaların %5–30’unu etkiler ve artmış mortalite (%40–90), uzamış YBÜ yatışı ve daha yüksek sağlık maliyetleri ile ilişkilidir. Akciğer ve böbrek hasarı arasındaki karşılıklı etkileşim giderek daha fazla tanınmakla birlikte, AKI’nin mekanik ventilasyondan (MV) ayırma sürecine etkisi yeterince araştırılmamıştır. Bu çalışma, YBÜ hastalarında AKI’nin MV’den ayırma sonuçları üzerindeki etkisini değerlendirmektedir. Yöntemler: Bu retrospektif kohort çalışma, Dahiliye Yoğun Bakım Ünitesi’nde (2010–2015) yürütüldü. Solunum yetmezliği nedeniyle entübe edilen ve en az 48 saat mekanik ventilasyon (MV) altında kalan ≥18 yaş hastalar dâhil edildi. Kronik böbrek hastalığı, kronik akciğer hastalığı veya kalp yetmezliği olan hastalar ile mekanik ventilasyon başladıktan sonra AKI gelişen hastalar çalışma dışı bırakıldı. AKI, KDIGO kriterlerine göre serum kreatinin düzeylerine dayanarak tanımlandı (48 saat içinde ≥0.3 mg/dL artış veya 7 gün içinde ≥1.5 kat artış). Retrospektif veri yapısı nedeniyle idrar çıkışı verileri tüm hastalar için güvenilir şekilde mevcut olmadığından AKI tanımında kullanılmadı. AKI, yoğun bakım sürecinde elde edilen veriler temel alınarak değerlendirildi ve yoğun bakım yatışı sırasında gelişmiş kabul edildi. AKI tanısı olan 100 hasta ile AKI olmayan 100 hasta karşılaştırıldı; demografik veriler (yaş, cinsiyet), laboratuvar parametreleri (kreatinin, albümin, hemoglobin, pH, PaO₂, PaCO₂), SOFA ve APACHE II skorları, sepsis durumu ve ventilatörden ayırma sonuçları analiz edildi. İstatistiksel analizlerde Student t-testi, Ki-kare testi ve çok değişkenli lojistik regresyon kullanıldı. Çok değişkenli modelde AKI durumu, yaş, APACHE II skoru, SOFA skoru, albümin düzeyi ve sepsis değişkenleri yer aldı. Bulgular: Genel MV’den ayırma başarısı %28’di (56/200). AKI grubunda başarı oranı %13 iken AKI olmayan grupta %43 idi (p 0.05). Sonuç: AKI, yoğun bakım hastalarında mekanik ventilasyondan ayırma sürecini anlamlı ölçüde olumsuz etkilemektedir. Hastalık şiddeti için düzeltme yapıldıktan sonra dahi, AKI ventilatörden ayırma başarısızlığının bağımsız bir belirleyicisi olarak kalmaktadır. AKI’nin erken tanınması, klinik yönetimi iyileştirebilir ve başarılı ventilatörden ayırmayı kolaylaştırabilir.
