The Clinical Significance of Fluctuations in the Minute-to-minute Urine Flow Rate and in its Minute-to-minute Variability During Septic Events in Critically Ill Patients.
Septic events complicated by hemodynamic instability can lead to decreased organ perfusion, multiple organ failure, and even death. Acute renal failure is a common complication of sepsis, affecting up to 50-70 % of cases, and it is routinely diagnosed by close monitoring of urine output. We postulated that analysis of the minute-to-minute changes in the urine flow rate (UFR) and also of the changes in its minute-to-minute variability might lead to earlier diagnosis of renal failure. We accordingly analyzed the clinical significance of these two parameters in a group of critically ill patients suffering from new septic events. ⋯ We consider that minute-to-minute changes in UFR and UFRV could potentially serve as early and sensitive signals of clinical deterioration during new septic events in critically ill patients. We also suggest that these parameters might be able to identify the optimal endpoint for the administration of fluid resuscitative measures in such patients.
