Comparison of hemodynamic indices of dialysis patients in continuous renal replacement therapy and intermittent renal replacement therapy methods with ultrasonic cardiac output monitor in intensive care unit

خلاصه انگلیسی

Introduction: Acute kidney injury (AKI) is a common complication in the intensive care unit (ICU) and is independently associated with end-stage renal disease and higher mortality in the ICU. There are different methods to supporting kidney function in critically ill patients. The renal replacement therapy (RRT) can be conducted continuously, intermittently, or in combination. Objectives: The purpose of our study is to investigate the hemodynamic indices of dialysis patients in the ICU by two methods high flow continuous renal replacement therapy (CRRT) and intermittently renal replacement therapy (IRRT) of ultrasonic cardiac output monitor (USCOM). Patients and Methods: In this study conducted at Sina hospital, patients requiring dialysis hospitalized to the ICU were studied. Around 48 patients benefited from rapid CRRT or IRRT in the opinion of a specialist. Basic patient information was recorded. To check hemodynamic parameters during dialysis, USCOM was carried out to check corrected flow time value (FTc) parameters, systemic vascular resistance (SVR) and cardiac output. Results were compared between the IRRT and CRRT groups. Results: This study was conducted on 48 patients who were candidates for dialysis. Patients were divided into high flow CRRT and IRRT groups based on clinical indications. In CRRT group, 19 patients (79.2%) and in the IRRT group, 20 patients (83.3%) were male (P=0.712). Their mean age was 68.70 ± 8.25 years in the CRRT group and 68.58 ± 7.19 years in the IRRT group. All patients had cardiac output monitored using USCOM or ultrasound. The mean Sequential Organ Failure Assessment (SOFA) score in the CRRT group was 7 and in the IRRT group was 6, with no significant difference among them. FTc value variable or modified flow time in the carotid artery, cardiac output, cardiac index, SVR variable and mean arterial pressure in in the two groups at four evaluated times (before dialysis, 15 minutes later, one hour later and end of dialysis) from the study the difference were not statistically significant. Conclusion: Although previos studies have recommended CRRT, our study showed significant difference may not be existed between IRRT and CRRT.
