Abstract
Introduction: Continuous renal replacement therapy (CRRT) is the gold standard renal
replacement therapy (RRT) for hemodynamically unstable patients.
Objectives: To study the characteristics and survival of patients undergoing CRRT in Iran.
Patients and Methods: This is a retrospective study conducted on 58 patients indicated for CRRT
at the Shahid-Modarres hospital of Tehran during 2016-2017. Gender, age, underlying diseases,
comorbidities, history of surgery, dialysis indication, and survival were gathered by reviewing
patients’ medical records. The data was analyzed in SPSS version 21.
Results: Sepsis constituted the most common underlying condition at admission. Overall,
continuous venovenous hemodialysis (CVVHD) was performed in 72.4% of the patients. Diabetes
and hypertension were the most common causes leading to RRT. The most common indication for
CRRT was unstable hemodynamic condition. The patients were most frequently referred from ICU
(34.5%), emergency department (20.7%), and CCU (15.5%).
Conclusion: We here reviewed the characteristics of hemodynamically unstable patients
undergoing CRRT. Our findings can help to understand the most important indications for CRRT
and to standardize CRRT practice in Iran.
