The purpose of this study is to examine the placement, timing, associated complications, efficacy of temporary and tunneled catheters for renal replacement therapy in patient with acute kidney injury.
The purpose of this study is to examine the placement, timing, associated complications, efficacy of temporary and tunneled catheters for renal replacement therapy in patient with acute kidney injury. In particular, we will be assessing renal replacement adequacy for patients on dialysis and continuous veno-venous hemofiltration by monitoring urea reduction ratios, venous and arterial pressures. We will also be monitoring infection rates. We will compare these outcomes in patients receiving tunneled catheters and patients receiving temporary catheters.
Study Type
OBSERVATIONAL
Enrollment
150
Brigham and Women's Hospital
Boston, Massachusetts, United States
Dialysis adequacy
Adequacy will be measured using urea reduction ratio for patients on intermittent hemodialysis. For continuous renal replacement therapy, we will record the maximum blood flow rate achievable. These measurements/recordings will be made on average within 1-3 days of starting therapy.
Time frame: up to 7d after starting renal replacement therapy
blood stream infection rates
Patients will be followed throughout their hospitalization, which can range from a few days to several weeks. Bloodstream infections within 30d of catheter placement will be recorded.
Time frame: within 30d of catheter placement
