lactate in trauma

Katalin Gornicsar, Tibor Mózes, Andor Grosz, Edit Bíró, Szabolcs Ládi, Paul Clayton
BACKGROUND: Multiple studies have found gender-based disparities in ICU admission rates and in complications following trauma. Female gender was associated with lower mortality when comparing patients less than 50 years of age. These data suggest an important role for cycle rather than gender itself. Our previous results indicate a crucial role for tumor necrosis factor alpha (TNFα) in inducing nososocomial infections. HYPOTHESIS: Cycle is important for TNF and other female hormone productions...

PURPOSE: Despite the availability of different lactate clearance (LC) metrics for clinical use, it remains unknown which metric is superior as a clinical predictor for outcome, particularly in trauma patients. This retrospective study compared four previously described metrics of LC and examined the association between LC and outcome in trauma patients. METHODS: Lactate values of trauma patients admitted to a level I trauma center between 2010 and 2013 were retrieved from patient records...

BACKGROUND/OBJECTIVES: The safety of administering uncrossmatched, group O, cold-stored, whole blood (cWB) during civilian trauma resuscitation was evaluated. METHODS/MATERIALS: Male trauma patients with haemorrhage-induced hypotension who received leuko-reduced uncrossmatched group O+, low titer (<50) anti-A and -B, platelet-replete cWB during initial resuscitation were included. The biochemical markers of haemolysis (lactate dehydrogenase, total bilirubin, haptoglobin, creatinine, serum potassium) were measured on the day of cWB receipt (day 0), and over the next 2 days, reports of transfusion reactions and total blood product administration in first 24 h of admission were recorded...

BACKGROUND: Critical administration threshold (≥3 units of packed red blood cells/h or CAT+) has been proposed as a new definition for massive transfusion (MT) that includes volume and rate of blood transfusion. CAT+ has been shown to eliminate survivor bias and be a better predictor of mortality than the traditional MT (>10 units/24h). End-tidal CO2 (ET CO2) negatively correlates with lactate and is an early predictor of shock in trauma patients. We conducted a pilot study to test the hypothesis that low ET CO2 on admission predicts CAT+...

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...

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: After injury, base deficit (BD) and lactate are common measures of shock. Lactate directly measures anaerobic byproducts, whereas BD is calculated and multifactorial. Although recent studies suggest superiority for lactate in predicting mortality, most were small or analyzed populations with heterogeneous injury severity. Our objective was to compare initial BD with lactate as predictors of inhospital mortality in a large cohort of blunt trauma patients all presenting with hemorrhagic shock...

BACKGROUND: Serum lactate serves as a surrogate marker for global tissue hypoxia following traumatic injury and has potential to guide resuscitation. Portable, handheld point-of-care monitoring devices enable lactate values to be readily available in the prehospital environment. The current review examines the utility of prehospital lactate (pLa) measurement in the management of trauma. METHODS: MEDLINE and EMBASE databases were searched using predefined criteria (pLa measurement, trauma patients) until March 10, 2016...

INTRODUCTION: We have recently shown that human whole blood stored at 4°C maintains hemostatic and platelet function. In this study, we compared restoration of hemodynamic, metabolic and hemostatic function after limited resuscitation with rat fresh whole blood, rat stored whole blood, or Lactated Ringers in traumatized rats. METHODS: Rat whole blood was stored for 10 days at 4°C for evaluation of hemostatic function. Polytrauma was performed on isoflurane-anesthetized Sprague-Dawley rats (350-450 g) by damage to the intestines, liver, right leg skeletal muscle and right femur fracture, followed by 40% hemorrhage...

BACKGROUND: Impact of early systemic hemodynamic alterations and fluid resuscitation on outcome in the modern burn care remains controversial. We investigate the association between acute-phase systemic hemodynamics, timing of fluid resuscitation and outcome in critically ill burn patients. METHODS: Retrospective, single-center cohort study was conducted in a university hospital. Forty critically ill burn patients with total body surface area (TBSA) burn-injured >20 % with invasive blood pressure and cardiac output monitoring (transpulmonary thermodilution technique) within 8 h from trauma were included...

BACKGROUND: Women who are breastfeeding often consult their general practitioner (GP) with concerns about nipple and breast pain, or the adequacy of their milk supply. Common concerns for their breastfed infant include slow weight gain, 'fussiness' with breastfeeding and 'funny stools'. OBJECTIVE: This article offers suggestions for clinicians to support breastfeeding women and their infants. DISCUSSION: Good attachment to the breast is important to reduce nipple pain and trauma, and to ensure adequate breast drainage and ongoing milk supply...

BACKGROUND: Suspended animation-like states have been achieved in small animal models, but not in larger species. Inducing metabolic suppression and temporary oxygen-independence could enhance survivability of massive injury. Based on prior analyses of key pathways, we hypothesized that PI3-kinase inhibition (PI3-KI) would produce metabolic suppression without worsening organ injury or systemic physiology. METHODS: Twenty swine were studied using LY294002 (LY), a non-selective PI3-KI: Animals were assigned to Trauma only (TO, N=3); DMSO only (DMSO, N=4), LY drug only (LYO, N=3); and Drug + trauma (LY+T , N=10) groups...

BACKGROUND: The time course of blood lactate levels could be helpful to assess a patient's response to therapy. Although the focus of published studies has been largely on septic patients, many other studies have reported serial blood lactate levels in different groups of acutely ill patients. METHODS: We performed a systematic search of PubMed, Science Direct, and Embase until the end of February 2016 plus reference lists of relevant publications. We selected all observational and interventional studies that evaluated the capacity of serial blood lactate concentrations to predict outcome...

Addenbrooke's Hospital, the Major Trauma Centre for the East of England Trauma Network, received 1070 major trauma patients between 1st January and 31st December 2014. In order to improve care, an audit was performed of 59 patients meeting our own selection criteria for orthopaedic polytrauma between 1st January 2013 and 31st December 2013. The Cambridge Polytrauma Pathway was devised through NCEPOD guidelines, literature review, internal and external discussion. It facilitates provision of best practice Early Appropriate Care, encompassing - multidisciplinary consultant decisions around the patient in our Neurological and Trauma Critical Care Unit, early full body trauma CT scans, serial measurements of lactate and fibrinogen levels, and out-of-hours orthopaedic theatre reserved for life-and-limb threatening injuries...

This study evaluated the long-term prognosis of return to normal mechanical milking after reconstructive teat surgery and determined the factors that have an impact on the outcome. A retrospective study of 67 dairy cows with teat lacerations was performed. Milking status at discharge and at long-term follow-up was adequate for 83% and 75% of the cows, respectively. No statistically significant differences were detected between the long-term prognosis and the age of the cow, the stage of lactation at presentation, or the configuration of the laceration...

INTRODUCTION: Acute traumatic coagulopathy (ATC) is an endogenous coagulopathy that develops following tissue injury and shock. The pathogenesis of ATC remains poorly understood, with platelet dysfunction, activation of the protein C pathway, and endothelial glycocalyx shedding all hypothesized to contribute to onset. The primary aim of this study was to develop an ovine model of traumatic coagulopathy, with a secondary aim of assessing proposed pathophysiological mechanisms within this model...

Measurement of trauma center performance presently relies on W-score calculation and comparison to national data sets. A limitation to this practice is a skewing of the W score, as it determines overall performance of a trauma population that is often heavily weighted by patients of low acuity. The University of Virginia relative mortality metric (RMM) was formulated to provide higher resolution in identifying areas of performance improvement within subpopulations of a trauma center using traditional Trauma Injury Severity Score methodology...
