PURPOSE: Lactate reduction, a common method of risk stratification, has been variably defined. Among patients with an initial lactate >4mmol/L, we compared mortality prediction between a subsequent lactate ≥4mmol/L to a <10% and <20% decrease between initial and subsequent lactate values. MATERIALS AND METHODS: We performed a single-center retrospective study of patients presenting to the emergency department with an initial lactate ≥4mmol/L and suspected infection...

This study investigated the diagnostic value of soluble urokinase plasminogen activator receptor (suPAR) and serum lactate in elderly patients with sepsis and evaluated their capacity to predict mortality and their correlation to Sequential Organ Failure Assessment (SOFA) score. The study included 80 participants, divided into two groups: 40 cases (mean age, 68.9 ± 5.9) admitted to the intensive care unit and 40 healthy controls (mean age, 67.1 ± 6.2). Elderly patients with sepsis had significantly higher levels of serum suPAR and lactic acid compared to healthy controls...

INTRODUCTION: The Surviving Sepsis Campaign guidelines recommend early goal-directed therapy (EGDT) for the resuscitation of patients with sepsis; however, the recent evidences quickly evolve and convey conflicting results. We performed a meta-analysis to evaluate the effect of EGDT on mortality in adults with severe sepsis and septic shock. METHODS: We searched electronic databases to identify randomized controlled trials that compared EGDT with usual care or lactate-guided therapy in adults with severe sepsis and septic shock...

Hyperlactatemia predicts mortality in patients with sepsis and septic shock, and its normalization is a potential treatment goal. We investigated the association of blood lactate and its changes over time with 90-day mortality in septic shock. We performed a post hoc analysis of 513 septic shock patients with admission blood lactate measurements in the prospective, observational, multicenter FINNAKI study. Repetitive lactate measurements were available in 496 patients for analyses of change in lactate values during ICU stay...

IFN regulatory factor (IRF)3 plays a detrimental role in the cecal ligation and puncture (CLP) mouse model of sepsis. However, it is unclear which pathway activates IRF3 in this context. In this report we investigate two pathways that activate IRF3: the Stimulator of Interferon Genes (STING) pathway (which senses cytosolic DNA) and the TIR-domain-containing adapter-inducing interferon-β (TRIF) pathway (which sense dsRNA and LPS via Toll-like receptor (TLR) 3 and 4). Initially, we examine the impact of these pathways using a severe CLP model (∼90% mortality)...

OBJECTIVE: To describe the effect of liver disease (LD) on lactate clearance during early sepsis resuscitation. METHODS: This is a multicenter randomized clinical trial. An initial lactate >2 mmol/L and subsequent serum lactate measurement within 6 hours were required for inclusion. LD was categorized by two methods: 1) past medical history (PMH) categorized as no LD, mild LD (no Child's score criteria, but PMH of hepatitis B/C), cirrhosis; and 2) measurable liver dysfunction determined by the liver component of the sequential organ failure assessment (L-SOFA) score as no dysfunction (L-SOFA score 0), mild dysfunction (score 1), moderate-severe dysfunction (score 2 to 4)...

Lactic acidosis is common in critical care; by contrast, a subtype called alcohol-associated lactic acidosis (AALA) is rarely encountered. The primary purpose of this study was to determine the prognosis of AALA in critically ill patients and the second aim was to determine whether the survival was associated to the peak blood lactate concentration. An 8-year retrospective analysis of adult patients admitted to the intensive care unit (ICU) with AALA between January 2007 and December 2014 was considered in a tertiary care hospital...

PURPOSE: Although overall paediatric septic shock mortality is decreasing, refractory septic shock (RSS) is still associated with high mortality. A definition for RSS is urgently needed to facilitate earlier identification and treatment. We aim to establish a European society of paediatric and neonatal intensive care (ESPNIC) experts' definition of paediatric RSS. METHODS: We conducted a two-round Delphi study followed by an observational multicentre retrospective study...

BACKGROUND: Previous work established resuscitation parameters that minimize complications with early fracture management. This Early Appropriate Care (EAC) protocol was applied to patients with advanced age to determine if they require unique parameters to mitigate complications. METHODS: Between October 2010 and March 2013, 376 consecutive skeletally mature patients with unstable fractures of the pelvis, acetabulum, thoracolumbar spine, and/or proximal or diaphyseal femur fractures were treated at a level I trauma center and were prospectively studied...

Antimicrobial therapy for sepsis has beneficial effects, but prolonged use fosters emergence of resistant microorganisms, increases cost, and secondary infections. We tested whether 3 days versus 5 days of antibiotics in the murine model of cecal ligation and puncture (CLP) negatively influences outcomes. Following CLP mice were randomized to receive the antibiotic imipenem-cilastatin (25mg/kg) in dextrose 5% in Lactated Ringer's solution every 12 hours for either three or five days. Serial monitoring over 28 days included body weight, temperature, pulse oximetry, and facial vein sampling for hematological analysis and glucose...

BACKGROUND: Serial lactate measurements over time or lactate clearance has been reported to be clinically reliable for risk stratification in different pathologic conditions ranging from sepsis to trauma, but no data are so far available on the behavior of lactate during venovenous extracorporeal membrane oxygenation (VV-ECMO) support in refractory adult acute respiratory distress syndrome (ARDS). METHODS: We assessed lactate values during VV-ECMO support and the prognostic role of lactate clearance at 6, 24, and 72 hours after ECMO start in 126 consecutive patients with refractory ARDS treated with VV-ECMO...

BACKGROUND: Jehovah's Witnesses (JW) are a Christian faith with > 1 million members in the United States who do not accept autologous blood transfusions. The optimal management of these patients undergoing neurosurgical procedures is not well defined. Here, we examined the feasibility and safety of JW undergoing neurosurgery in a blood management program. STUDY DESIGN AND METHODS: Sixty-eight JW patients including 23 males and 45 females (mean age 53 +/- 12 years) who underwent a variety of cranial (n=19) and spinal (n=49) neurosurgical procedures over a 5-year period were identified retrospectively and their hospital charts, anesthetic records and operative reports reviewed...

BACKGROUND AND AIMS: The choice of vasopressor for treating cirrhosis with septic shock is unclear. While noradrenaline in general is the preferred vasopressor, terlipressin improves microcirculation in addition to vasopressor action in non-cirrhotics. We compared the efficacy and safety of noradrenaline and terlipressin in cirrhotics with septic shock. PATIENTS AND METHODS: Cirrhotics with septic shock underwent open label randomization to receive either terlipressin (n=42)or noradrenaline (n=42) infusion at a titrated dose...

INTRODUCTION: We aimed to pilot test the delivery of sepsis education to emergency medical services (EMS) providers and the feasibility of equipping them with temporal artery thermometers (TATs) and handheld lactate meters to aid in the prehospital recognition of sepsis. METHODS: This study used a convenience sample of prehospital patients meeting established criteria for sepsis. Paramedics received education on systemic inflammatory response syndrome (SIRS) criteria, were trained in the use of TATs and hand-held lactate meters, and enrolled patients who had a recent history of infection, met ≥ 2 SIRS criteria, and were being transported to a participating hospital...

PURPOSE: Screening of patients with sepsis is needed to increase recognition and allow for earlier interventions. There is no consensus on whether the addition of lactate to the critical result laboratory's call list should be a standard practice. MATERIALS AND METHODS: This was a retrospective cohort study that compared management and outcomes of patients with sepsis having lactate ≥4 mmol/L before (group 1) and after (group 2) the addition of a critical result threshold of lactate of ≥4 mmol/L to the critical result laboratory's call list and its effects on time to antibiotics and intravenous fluids (IVFs)...
