REVIEW
Rob Loflin, Michael E Winters
Since its original description in 1832, fluid resuscitation has become the cornerstone of early and aggressive treatment of severe sepsis and septic shock. However, questions remain about optimal fluid composition, dose, and rate of administration for critically ill patients. This article reviews pertinent physiology of the circulatory system, pathogenesis of septic shock, and phases of sepsis resuscitation, and then focuses on the type, rate, and amount of fluid administration for severe sepsis and septic shock, so providers can choose the right fluid, for the right patient, at the right time...

Acute heart failure is still characterized by poor prognosis with high mortality. Diagnosis is based on clinical symptoms and hemodynamic measurements. Early coronary revascularization in cardiogenic shock complicating myocardial infarction improves outcome. The further contemporary therapeutic options in the management of acute heart failure are limited to a merely symptomatic effect with relief of dyspnea, reduction of volume overload and improvement of hemodynamic parameters by vasodilators (in hypertension) or inotropic and vasopressor agents (in hypotension)...

The benefits and disadvantages of pulsatility in mechanical circulatory support devices have been argued since before the first use of cardiopulmonary bypass (CPB) with a nonpulsatile pump. The debate over the superiority of either pulsatile or nonpulsatile perfusion during CPB persists, but recently, the evidence in favor of pulsatile perfusion during CPB is increasing. Complications associated with chronic nonpulsatile flow in patients implanted with left ventricular assist devices have renewed interest in generating pulsatility with these devices...

COMMENT
Federico Pappalardo, Andrea Montisci
Post-cardiotomy cardiogenic shock (PCCS) is a complication of heart surgery associated with a poor prognosis: veno-arterial extracorporeal membrane oxygenation (VA ECMO) ensures end-organ perfusion while fully replacing heart and lung function, though it is associated with unsatisfactory results. Few studies have identified reliable predictors of poor prognosis early in the course of extracorporeal support. A recent study showed the strong prognostic power of urine output in the first 24 hours of VA ECMO in predicting early and late mortality of PCCS...

Tachyarrhythmia-induced cardiomyopathy (TIC) is a rare, yet life-threatening phenomenon in children. TIC has been defined as myocardial dysfunction that is entirely or partially reversible after control of the responsible tachyarrhythmia and is typically caused by an incessant supraventricular tachycardia. In cases of unsuccessful termination of the tachycardia, cardiogenic shock may occur. Several authors favour the use of mechanical circulatory support in such cases. Particularly with regard to these partly severe cases, the authors would like to present the option of transoesophageal overdrive pacing (TOP) as a tool for initial heart rate control and hemodynamic stabilization of patients with TIC refractory to conventional strategies of tachycardia termination...

BACKGROUND: Refractory post-cardiotomy cardiogenic shock (PCCS) is a relatively rare phenomenon that can lead to rapid multi-organ dysfunction syndrome and is almost invariably fatal without advanced mechanical circulatory support (AMCS), namely extra-corporeal membrane oxygenation (ECMO) or ventricular assist devices (VAD). In this multicentre observational study we retrospectively analyzed the outcomes of salvage venoarterial ECMO (VA ECMO) and VAD for refractory PCCS in the 3 adult cardiothoracic surgery centres in Scotland over a 20-year period...

OBJECTIVES: The use of short-term mechanical circulatory support (MCS) has increased in the treatment of refractory cardiogenic shock (RCS). Percutaneous short-term MCS technology has emerged rapidly; however, limitations in flow and durability remain. We therefore investigated a minimally invasive surgical approach using an external ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) in patients with RCS. METHODS: Twenty-five patients underwent minimally invasive external VAD insertion with a magnetically levitated centrifugal pump for various causes of cardiogenic shock between April 2010 and May 2016...

BACKGROUND: The lack of a patent source of infection after 24 hours of management of shock considered septic is a common and disturbing scenario. We aimed to determine the prevalence and the causes of shock with no diagnosis 24 hours after its onset, and to compare the outcomes of patients with early-confirmed septic shock to those of others. METHODS: We conducted a pragmatic, prospective, multicenter observational cohort study in ten intensive care units (ICU) in France...

BACKGROUND: Despite advances in treatment, mortality in acute myocardial infarction complicated by cardiogenic shock remains high. Short-term mechanical circulatory support devices acutely improve hemodynamic conditions. The Impella CP is a new percutaneous circulatory support device that provides more hemodynamic support than the intra-aortic balloon pump (IABP). OBJECTIVES: The aim of this study was to determine whether the Impella CP can decrease 30-day mortality when compared with IABP in patients with severe shock complicating acute myocardial infarction...

INTRODUCTION: The cardiac manifestations of influenza A are broad, ranging from self-limited pericarditis to fatal cardiomyopathy. The 2009 H1N1 influenza A (H1N1) strain is a rare cause of pericarditis, and its role in developing a pericardial effusion leading to tamponade has infrequently been reported. CASE PRESENTATION: We describe a case of a young female with no prior cardiovascular history who presents with a pericardial effusion and shock secondary to cardiac tamponade from pericarditis due to H1N1 influenza A...

REVIEW
Matthew J Delano, Peter A Ward
Sepsis occurs when an infection exceeds local tissue containment and induces a series of dysregulated physiologic responses that result in organ dysfunction. A subset of patients with sepsis progress to septic shock, defined by profound circulatory, cellular, and metabolic abnormalities, and associated with a greater mortality. Historically, sepsis-induced organ dysfunction and lethality were attributed to the complex interplay between the initial inflammatory and later anti-inflammatory responses. With advances in intensive care medicine and goal-directed interventions, early 30-day sepsis mortality has diminished, only to steadily escalate long after "recovery" from acute events...

Hypoxic hepatitis (HH), also known as ischemic hepatitis or shock liver, is characterized by a massive, rapid rise in serum aminotransferases resulting from reduced oxygen delivery to the liver. The most common predisposing condition is cardiac failure, followed by circulatory failure as occurs in septic shock and respiratory failure. HH does, however, occur in the absence of a documented hypotensive event or shock state in 50% of patients. In intensive care units, the incidence of HH is near 2.5%, but has been reported as high as 10% in some studies...

BACKGROUND: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an effective technique for providing emergency mechanical circulatory support for patients with cardiogenic shock. VA-ECMO enables a rapid restoration of global systemic organ perfusion, but it has not been found to always show a parallel improvement in the microcirculation. We hypothesized in this study that the response of the microcirculation to the initiation of VA-ECMO might identify patients with increased chances of intensive care unit (ICU) survival...

Shock is a systemic form of acute circulatory failure leading to cellular dysoxia and death. Such a state of aerobic metabolism failure also underlies neuronal cell death in severe traumatic brain injury. It is becoming increasingly recognized that ischemic hypoxia is not the sole mechanism and that multiple alternate cooperating mechanisms may be responsible for compromising neuronal oxidative metabolism. These different mechanisms can be usefully understood via analysis of the classic subdivisions of tissue hypoxia...

OBJECTIVE: In elderly hypertensive patients, systolic blood pressure (sBP) goals recommended by US and European guidelines (ESH) for the initiation of treatment are more liberal than in younger patients because of an increased risk of treatment-associated side-effects and hypotension. Carotid stenosis increases with age and poses a risk of brain ischemia if hypotension occurs. Its relevance for the routine care of elderly hypertensives, however, remains unclear. We analyzed data on precerebral artery morphology and BP evolution from a survey of aged hospitalized patients...

INTRODUCTION: Mechanical circulatory support may be considered as a therapeutic option in selected patients with refractory cardiac arrest (rCA). Animal studies suggest a potential role for the Impella(®) left ventricular assist device in this setting, but so far no human data have been published. METHODS: Eight patients with rCA were treated with the Impella CP(®) device at our institution from November 2014 to October 2015. The Impella CP(®) was used at the discretion of the treating physicians in patients with rCA and pulseless electrical activity with presumed primary left ventricular failure...

Some experimental data suggest that rapid bolus administration of albumin causes less plasma-expanding effects than slow, continuous infusion. To determine whether rapid bolus administration, in comparison with slow infusion, results in greater extravasation of albumin in experimental septic shock we performed a randomized controlled trial with 32 endotoxemic pigs. The animals were monitored and ventilated with standard intensive care equipment and given 10 mL x kg 5% albumin labeled with Technetium-99m, either as a rapid 15-minute bolus (Bolus group, n = 16) or as a 2-hour (h) infusion (Infusion group, n = 16)...
