INTRODUCTION: Explosion injury is very common on the battlefield and is associated with major burn and inhalation injuries and subsequent high mortality and morbidity rates. Here we report six victims who suffered from explosion injuries caused by stun grenade; all were treated with extracorporeal membrane oxygenation (ECMO) as salvage therapy. This study was aimed to evaluate the indications and efficacy of ECMO in acute and critically ill major burn patients. METHODS: This was a retrospective analysis of six patients from Tri-Service General Hospital, National Defense Medical Center in Taiwan...

The role and timing of percutaneous mechanical circulatory support (MCS) devices in the treatment of acute myocardial infarction complicated by cardiogenic shock (AMICS) are not well understood. We sought to evaluate patient characteristics and predictors of outcomes in patients presenting with AMICS supported with an axial flow percutaneous MCS device; 287 consecutive unselected patients enrolled in the catheter-based ventricular assist device registry presenting with AMICS who underwent percutaneous coronary intervention (PCI) were included in this analysis...

The current management of patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is associated with a high rate of mortality, despite widespread regional implementation of rapid transfer to percutaneous coronary intervention-capable centres for prompt infarct-related artery reperfusion. The limited clinical effectiveness of early revascularization in patients with AMI-CS might be secondary to the extent of coronary artery disease in these patients and the risk of incomplete revascularization, as well as the lower probability of achieving successful reperfusion compared with acute myocardial infarction without hemodynamic instability...

Three basic principles provide the rationale for the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database (CHSD) public reporting initiative: (1) Variation in congenital and pediatric cardiac surgical outcomes exist. (2) Patients and their families have the right to know the outcomes of the treatments that they will receive. (3). It is our professional responsibility to share this information with them in a format they can understand. The STS CHSD public reporting initiative facilitates the voluntary transparent public reporting of congenital and pediatric cardiac surgical outcomes using the STS CHSD Mortality Risk Model...

Acute left ventricular dysfunction in children justifies aggressive treatment because of the high potential for complete recovery. The options for providing mechanical support to the failing heart in a child include extracorporeal membrane oxygenation, left ventricular assist devices, and the use of the intra-aortic balloon pump (IABP). The IABP is a commonly used method of temporary circulatory support in adults. However, despite the availability of pediatric size balloons, the usage of IABP for temporary circulatory support in children has not been widespread...

Peroxynitrite is a powerful oxidant, formed from the reaction of nitric oxide and superoxide. It is known to interact and modify different biological molecules such as DNA, lipids and proteins leading to alterations in their structure and functions. These events elicit various cellular responses, including cell signaling, causing oxidative damage and committing cells to apoptosis or necrosis. This review discusses nitrosative stress-induced modification in the DNA molecule that results in the formation of 8-nitroguanine and 8-oxoguanine, and its role in disease conditions...

Extracorporeal life support (ECLS) describes a system that involves drainage from the venous circulation and return via an oxygenator into the arterial circulation (veno-arterial extracorporeal membrane oxygenation). ECLS provides effective cardiopulmonary support, but the parallel circulation has complex effects on the systemic and pulmonary circulatory physiology. An understanding of the physiological changes is fundamental to the management of ECLS. In this review, the key physiological concepts and the implications on the clinical management of ECLS are discussed...

Retropharyngeal hematoma following blunt cervical spine injury is a known cause of airway obstruction, but it is not known to cause hemorrhagic shock. We report the case of a massive retropharyngeal hematoma caused by a blunt vertebral artery transection leading simultaneously to airway obstruction and hemorrhagic shock. An 83-year-old woman was injured in a motorcycle accident. In the field, the patient exhibited paradoxical breathing with no breath sounds, and her blood pressure could not be measured. Therefore, emergency intubation and fluid resuscitation were initiated and the patient was transferred to the emergency department...

OBJECTIVE: The role of short-term mechanical circulatory support has increased in patients with refractory cardiogenic shock. However, limited data exist on the outcomes of a bridge to a durable left ventricular assist device strategy using short-term mechanical circulatory support. METHODS: We retrospectively reviewed 382 patients who underwent continuous-flow left ventricular assist device insertion between 2004 and 2014. Of these, 45 (12%) were bridged with short-term mechanical circulatory support devices for refractory cardiogenic shock...

The past decade has seen an exponential increase in the application and development of durable long-term as well as nondurable short-term mechanical circulatory support for cardiogenic shock and acute or chronic heart failure. Support has evolved from bridge-to-transplant to destination therapy, bridge to rescue, bridge to decision making, and bridge to a bridge. Notable trends include device miniaturization, minimally invasive and/or percutaneous insertion, and efforts to superimpose pulsatility on continuous flow...

REVIEW
Jan Bakker
In this review, the relationship between changes in macrohemodynamics during the development and treatment of acute circulatory failure is discussed in the context of coherence with microcirculation and changes in lactate. In models of circulatory failure, coherence between changes in macrocirculatory and microcirculatory perfusion and coherence with subsequent changes in lactate levels are more or less preserved. However, in patients, particularly those with septic shock, these relationships are much less clear...

Critical illness associated with cardiac pump failure results in reduced tissue perfusion in all organs and occurs in various conditions such as sepsis, cardiogenic shock, and heart failure. Mechanical circulatory support (MCS) devices can be used to maintain organ perfusion in patients with cardiogenic shock and decompensated chronic heart failure. However, correction of global hemodynamic parameters by MCS does not always cause a parallel improvement in microcirculatory perfusion and oxygenation of the organ systems, a condition referred to as a loss of hemodynamic coherence between macro- and microcirculation (MC)...

Cardiogenic shock is an acute life-threatening condition, which results in impaired end-organ perfusion and oxygenation. Invasive ventilation and medicinal treatment with inotropes or vasopressors are necessary in most cases; however, they are also associated with reduced long-term prognosis. Frequently, medical treatment is not even sufficient to stabilize the patient; therefore, dedicated mechanical circulatory support devices that actively reduce the load on the left ventricle were developed to allow myocardial recovery or to gain time until definitive treatment...

The both aims of this single-centre, retrospective study were to analyse the outcomes and to identify the independent predictors of 30-day and long-term mortality in case of cardiopulmonary resuscitation requiring extracorporeal life support (ECLS) in the elderly.From October 2004 to May 2014, 163 patients with a mean age of 75.5 years [range 70-91] required veno-arterial ECLS. The main indication was post-cardiotomy cardiogenic shock (79.6%). ECLS duration averaged 5.6 ± 4.3 days. Thirty-day mortality was 72% (n=117) and follow-up survival rate was 14...
