Criteria for Continuous Kidney Replacement Therapy Cessation in ICU Patients
INTRODUCTION: In intensive care unit (ICU) patients with acute kidney injury, specific recommendations to guide the decision to cease continuous kidney replacement therapy (CKRT) are lacking. METHODS: We performed a survey to identify criteria currently used to cease CKRT in real-life clinical practice in the Netherlands. We used an online questionnaire with multiple choice questions designed with web-based software from SurveyMonkey. RESULTS: We received 169 completed questionnaires from intensivists (n = 126) and nephrologists (n = 43). Essential determinants for the cessation of CKRT were a spontaneously increasing diuresis (indicated by 92% of the respondents), absence of fluid overload (indicated by 88% of the respondents), and improvement in creatinine clearance (indicated by 61% of the respondents; intensivists 56%; nephrologists 77%, p = 0.03). Most often mentioned cut-off values used for increase in diuresis were 0.25 and 0.5 mL/kg/h (35% and 33%, respectively). Actual CKRT cessation was often postponed until the filter clots or until circuit disconnection is needed because of patient transport for diagnostic or intervention procedures (indicated by 58% of the respondents). Expected discharge from the ICU was the most frequently reported determinant to switch from CKRT to hemodialysis (indicated by 67% of the respondents). CONCLUSIONS: CKRT cessation in clinical practice is mostly based on spontaneously increasing diuresis, absence of fluid overload, and improvement in creatinine clearance and is often delayed until filter clotting or disconnection of the circuit because of logistic reasons
Ultrasound and NICOM in the assessment of fluid responsiveness in patients with mild sepsis in the emergency department: A pilot study
Objective We investigated whether combining the caval index, assessment of the global contractility of the heart and measurement of stroke volume with Noninvasive Cardiac Output Monitoring (NICOM) can aid in fluid management in the emergency department (ED) in patients with sepsis. Setting A prospective observational single-centre pilot study in a tertiary care centre. Primary and secondary outcomes Ultrasound was used to assess the caval index, heart contractility and presence of B-lines in the lungs. Cardiac output and stroke volume were monitored with NICOM. Primary outcome was increase in stroke volume after a fluid bolus of 500mL, while secondary outcome included signs of fluid overload. Results We included 37 patients with sepsis who received fluid resuscitation of at least 500mL saline. The population was divided into patients with a high (>36.5%, n=24) and a low caval index ( Conclusions Our small pilot study suggests that at least 1000mL saline is needed to induce a significant response in stroke volume in patients with sepsis and a high caval index. This amount seems to be safe, not leading to the development of fluid overload. Therefore, combining ultrasound and NICOM is feasible and may be valuable tools in the treatment of patients with sepsis in the ED. A larger trial is needed to confirm these results
