PURPOSE: Despite the recent Sepsis-3 consensus, the Systemic Inflammatory Response Syndrome (SIRS) criteria continue to be assessed and recommended. Such use implies equivalence and interchangeability of criteria. Thus, we aimed to test whether such criteria are indeed equivalent and interchangeable. MATERIALS AND METHODS: From 2000 to 2015, we identified patients with infection, organ failure, and at least one SIRS criterion in 179 Intensive Care Units in Australia and New...

The hemodynamic effects of intravenous (IV) paracetamol in patients undergoing cardiac surgery are unknown. We performed a prospective single center placebo controlled randomized study with parallel group design in adult patients undergoing elective cardiac surgery. Participants received paracetamol (1 gram) IV or placebo (an equal volume of 0.9% saline) preoperatively followed by two postoperative doses 6 hours apart. The primary endpoint was the absolute change in systolic (SBP) 30 minutes after the preoperative infusion, analysed using an ANCOVA model...

Suvi T Vaara, Rinaldo Bellomo
Continuous renal replacement therapy (CRRT) has many potential indications that extend beyond the traditional removal of uremic waste products. Many of these stem from the capacity of CRRT to remove middle-sized molecules and its suitability for haemodynamically unstable patients. Using CRRT for immunomodulation to remove circulating plasma cytokines has created great enthusiasm and, in the past, immunomodulation was a frequently reported indication for commencing CRRT. Unfortunately, recent evidence from randomized controlled trials has been discouraging, and CRRT cannot be recommended for immunomodulation...

OBJECTIVE: Limited studies have examined the association between diabetes and HbA1c with postoperative outcomes. We investigated the association of diabetes, defined categorically and HbA1c as a continuous measure, with postoperative outcomes. RESEARCH DESIGN AND METHODS: In this prospective, observational study, we measured the HbA1c of surgical inpatients age ≥54 years at a tertiary hospital between May 2013 and January 2016. Patients were diagnosed with diabetes if they had preexisting diabetes or an HbA1c ≥6...

INTRODUCTION: Accurate dosing of protamine reversal following on-pump cardiac surgical procedures is challenging, with both excessive and inadequate administration recognised to increase bleeding risk. We aimed to examine the relationship between three ratios for heparin reversal and markers of haemostasis. METHODS: A retrospective analysis of a prospectively collected database was undertaken at a single tertiary cardiac unit, reviewing all cases of on-pump coronary artery bypass grafts and single valve replacements from 01/01/2011 to 31/12/2015...

OBJECTIVE: Acute kidney injury requiring renal replacement therapy in severe vasodilatory shock is associated with an unfavorable prognosis. Angiotensin II treatment may help these patients by potentially restoring renal function without decreasing intrarenal oxygenation. We analyzed the impact of angiotensin II on the outcomes of acute kidney injury requiring renal replacement therapy. DESIGN: Post hoc analysis of the Angiotensin II for the Treatment of High-Output Shock 3 trial...

OBJECTIVES: In the absence of a universal definition of light or deep sedation, the level of sedation that conveys favorable outcomes is unknown. We quantified the relationship between escalating intensity of sedation in the first 48 hours of mechanical ventilation and 180-day survival, time to extubation, and delirium. DESIGN: Harmonized data from prospective multicenter international longitudinal cohort studies SETTING:: Diverse mix of ICUs. PATIENTS: Critically ill patients expected to be ventilated for longer than 24 hours...

INTRODUCTION: Supra-clinical doses of clonidine appear beneficial in experimental sepsis, but there is limited understanding of the effects of clonidine at clinically relevant doses. METHODS: In conscious sheep, with implanted renal and pulmonary artery flow probes, sepsis was induced by infusion of live Escherichia coli. At 24 hours, a high clinical dose of clonidine (HCDC) [1.0 μg/kg/h], a low clinical dose of clonidine (LCDC) [0.25 μg/kg/h] or vehicle, was infused for 8 hours...

REVIEW
Neil J Glassford, Rinaldo Bellomo
Acute kidney injury (AKI) is common, although commonly used clinical diagnostic markers are imperfect. Intravenous fluid administration remains a cornerstone of therapy worldwide, but there is minimal evidence of efficacy for the use of fluid bolus therapy outside of specific circumstances, and emerging evidence associates fluid accumulation with worse renal outcomes and even increased mortality among critically ill patients. Artificial colloid solutions have been associated with harm, and chloride-rich solutions may adversely affect renal function...

OBJECTIVES: Albumin is used to resuscitate trauma patients but may increase intracranial pressure (ICP). Its effects on renal blood flow and function are unknown. Our aim was to examine the effects of hypertonic albumin on ICP and renal function, and if any effects are due to the hypotonicity of the solution containing albumin or to albumin itself. DESIGN, SETTING AND SUBJECTS: Cross-over, randomised controlled experimental study of six adult Merino ewes in the animal facility of a research institute...

BACKGROUND: Although acute kidney injury (AKI) frequently complicates cardiac surgery, methods to determine AKI risk in patients without underlying kidney disease are lacking. Renal functional reserve (RFR) can be used to measure the capacity of the kidney to increase glomerular filtration rate under conditions of physiological stress and may serve as a functional marker that assesses susceptibility to injury. We sought to determine whether preoperative RFR predicts postoperative AKI...
