BACKGROUND: Sodium lactate seemed to improve fluid balance and avoid fluid overload. The objective of this study was to determine if these beneficial effects can be at least partly explained by an improvement in disseminated intravascular coagulation (DIC)-associated renal microvascular thrombosis. METHODS: Ancillary work of an interventional randomized open label controlled experimental study. Fifteen female "Large White" pigs (2 months old) were challenged with intravenous infusion of E...

The prognosis of septic shock is tightly linked to the earliness of both appropriate antibiotic therapy and early hemodynamic resuscitation. This latter is essentially based on fluid and vasopressors administration. The step-by-step strategy, called "early goal-directed therapy" (EGDT) developed in 2001 and endorsed by the Surviving Sepsis Campaign (SSC) between 2004 and 2016 is no longer recommended. Indeed, recent multicenter randomized clinical trials showed no reduction in all-cause mortality, duration of organ support and in-hospital length of stay with EGDT in comparison with standard care...

BACKGROUND: Central venous pressure (CVP) is an important factor affecting capillary blood flow, and it is associated with poor outcomes in adult septic shock patients. However, whether a similar association exists in pediatric patients remains unclear. METHODS: We retrospectively analyzed data from patients admitted to our pediatric intensive care unit (PICU) between February 2009 and July 2015. Patients were divided into two groups-survivors and nonsurvivors-according to 28-day mortality...

Traditional abrasive fluid jet polishing (FJP) is limited by its high-pressure equipment, unstable material removal rate, and applicability to ultra-smooth surfaces because of the evident air turbulence, fluid expansion, and a large polishing spot in high-pressure FJP. This paper presents a novel cavitation fluid jet polishing (CFJP) method and process based on FJP technology. It can implement high-efficiency polishing on small-scale surfaces in a low-pressure environment. CFJP uses the purposely designed polishing equipment with a sealed chamber, which can generate a cavitation effect in negative pressure environment...

BACKGROUND: During early treatment of haemorrhagic shock maintenance of cerebral and end-organ oxygen supply by fluid resuscitation is mandatory. Gelatin-polysuccinat (GP) recently regained attention despite a still unclear risk profile and widely unknown effects on cerebral and peripheral microcirculation. This study investigates the effects of GP versus balanced electrolyte solution (BEL) with focus on cerebral regional oxygen saturation and peripheral microcirculation in a porcine haemorrhagic shock model...

BACKGROUND: The World Health Organization (WHO) recommends rapid intravenous rehydration, using fluid volumes of 70-100mls/kg over 3-6 h, with some of the initial volume given rapidly as initial fluid boluses to treat hypovolaemic shock for children with acute gastroenteritis (AGE) and severe dehydration. The evidence supporting the safety and efficacy of rapid versus slower rehydration remains uncertain. METHODS: We conducted a systematic review of randomised controlled trials (RCTs) on 11th of May 2017 comparing different rates of intravenous fluid therapy in children with AGE and moderate or severe dehydration, using standard search terms...

PURPOSE: Postoperative vasoplegic shock after cardiac surgery seems to be a frequent complication with poor outcomes. We hypothesized that vasopressin may increase the risk of poor outcomes in patients with preoperative Left Ventricular Dysfunction (pLVD) rather than norepinephrine. The aim of this study was to assess whether vasopressin is superior to norepinephrine to improve outcomes in patients with pLVD after cardiac surgery. METHODS: This retrospective cohort study included 1,156 patients with postoperative vasoplegic shock (mean arterial pressure <65 mmHg resistant to fluid challenge and cardiac index >2...

INTRODUCTION: Hemorrhagic shock accounts for a large amount of trauma-related mortality. The severity of trauma can be further aggravated by an additional blunt chest trauma (TxT), which independently contributes to mortality upon the development of an acute lung injury (ALI). Besides, cigarette smoke (CS) exposure before TxT enhanced posttraumatic inflammation, thereby aggravating ALI. We therefore aimed to characterize the impact of an acute and/or chronic lung injury on organ dysfunction in a murine model of traumatic hemorrhagic shock (HS)...

INTRODUCTION: The opening of the round window and the insertion of the electrode array into the scala tympani during cochlear implant surgery can lead to a pressure shock of the delicate inner ear structures. By filling the tympanic cavity with Ringer Solution during these surgical steps (underwater technique), the hydrostatic pressure of the fluid acts as a smooth pressure stabilizer, avoiding a pressure shock of the inner ear structures. The aim of this retrospective study was to present long-term results of this new method of cochlear implantation in underwater technique...

OBJECTIVES: Our objectives were to determine first whether albumin prevents heparin-binding protein-induced increased endothelial cell permeability and renal cell inflammation and second, whether a plasma heparin-binding protein-to-albumin ratio predicts risk of acute kidney injury, fluid balance, and plasma cytokine levels in septic shock. DESIGN: In vitro human endothelial and renal cell model and observation cohort of septic shock. SETTINGS: Research laboratory and multicenter clinical trial (Vasopressin and Septic Shock Trial)...

Hypercapnia, elevated levels of CO2 in the blood, is a known marker for poor clinical prognosis and is associated with increased mortality in patients hospitalized with both bacterial and viral pneumonias. Although studies have established a connection between elevated CO2 levels and poor pneumonia outcomes, a mechanistic basis of this association has not yet been established. We previously reported that hypercapnia inhibits expression of key NF-κB-regulated, innate immune cytokines, TNF-α, and IL-6, in LPS-stimulated macrophages in vitro and in mice during Pseudomonas pneumonia...

This experimental study deals with the propagation of an ultrasonic shock wave in a random heterogeneous medium, constituted of identical 75μm radius bubbles, trapped in a yield-stress fluid. The fundamental frequency of the incident wave (in the MHz range) was much larger than the resonance frequency of bubbles (38kHz). A well-expanded coda, resulting from the multiple scattering of the incident shock wave through the heterogeneous medium, was experimentally measured in transmission. Despite the significant amplitude of the shock wave (90kPa), no sign of nonlinear response of the bubbles was detected...

Shock in newborn infants has unique etiopathologic origins that require careful assessment to direct specific interventions. Early diagnosis is key to successful management. Unlike adults and pediatric patients, shock in newborn infants is often recognized in the uncompensated phase by the presence of hypotension, which may be too late. The routine methods of evaluation used in the adult and pediatric population are often invasive and less feasible. We aim to discuss the pathophysiology in shock in newborn infants, including the transitional changes at birth and unique features that contribute to the challenges in early identification...

It has been demonstrated that tranexamic acid (TXA), a synthetic derivative of lysine, alleviates lung damage in a trauma-hemorrhagic shock (T/HS) model. Nevertheless, the mechanism of TXA against acute lung injury (ALI) has not deeply elaborated. In this study, we generated a T/HS rat model based on previous research, and TXA (50 mg/kg and 100 mg/kg) was intravenously injected into these rats prior to or post T/HS. The results revealed that the decreased survival rate and impaired lung permeability of the rats caused by T/HS were improved by TXA pretreatment or posttreatment...

RATIONALE: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease entity primarily described in children, but not less relevant in adults. It is characterized by a misdirected activation of the immune system, resulting in an uncontrolled cytokine release from macrophages and cytotoxic T-cells (CTLs). Primary HLH relies on a genetic predisposition, whereas secondary HLH develops in the context of infections, malignancies or autoimmune diseases. However, the awareness and therapeutic knowledge for HLH in adulthood is limited...

Grounded theory was used to generate a mid-range theory of the process of spiritual change in the lives of survivors of homicide victims. Theoretical sampling guided the selection of 30 participants from a larger study of spiritual change after homicide ( N = 112). Individual interviews were analyzed using a four-step sequence of line-by-line, focused, axial, and selective coding. Analysis generated a closed theory consisting of three fluids, consecutive but nonlinear stages. Each stage consisted of an overarching process and a state of being in the world: (a) Disintegrating: living in a state of shock; (b) Reckoning: living in a state of stagnation; (c) Recreating and reintegrating the self: living in a state of renewal...

BACKGROUND: Refractory peritonitis is defined as failure of clearance of peritoneal fluid despite 5 days of appropriate antibiotic therapy. Catheter removal decreases morbidity and mortality. Data on the outcomes of refractory peritonitis and of reinitiation of peritoneal dialysis (PD) in this group of patients are sparse. The present study analyzed etiology, outcomes, and prognostic factors of refractory peritonitis as well as survival of the reinitiation of the technique. METHODS: This was a single-center retrospective study that included 90 patients of refractory continuous ambulatory PD (CAPD) peritonitis at a tertiary care center in North India...
