Lower-extremity ischemia is a significant complication in children on femoral venoarterial extracorporeal membrane oxygenation (VA ECMO). Our institution currently routinely uses distal perfusion catheters (DPCs) in all femoral arterial cannulations in attempts to reduce ischemia. We performed a single-center, retrospective review of pediatric patients supported with femoral VA ECMO from January 2005 to November 2015. The outcomes of patients with prophylactic DPC placement at cannulation (prophylactic DPC) were compared to a historical group with DPCs placed in response only to clinically evident ischemic changes (reactive DPC)...

BACKGROUND: Primary graft dysfunction (PGD) is one of the most common causes of early death after orthotopic heart transplantation. Mechanical circulatory support devices are required for severe forms of PGD. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) and temporary ventricular assist device (VAD) support have both been reported to be useful for severe PGD. METHODS: Between January 2007 and December 2015, 597 patients received a heart transplant at our center...

Extracorporeal cardiopulmonary resuscitation (ECPR) is the use of rapid deployment venoarterial (VA) extracorporeal membrane oxygenation to support systemic circulation and vital organ perfusion in patients in refractory cardiac arrest not responding to conventional cardiopulmonary resuscitation (CPR). Although prospective controlled studies are lacking, observational studies suggest improved outcomes compared with conventional CPR when ECPR is instituted within 30-60 min following cardiac arrest. Adult and pediatric patients with witnessed in-hospital and out-of-hospital cardiac arrest and good quality CPR, failure of at least 15 min of conventional resuscitation, and a potentially reversible cause for arrest are candidates...

In spite of distal perfusion of the limb using a cannula, the limb can have ischemic events if there is an undetected kink or clot anywhere in the line or thrombus in the artery. There are several ways to monitor and assess the limb ischemia. Monitoring for clinical signs of limb ischemia like temperature change and pallor is reliable and mandatory. We report a method where we used color Doppler to document the blood flow. Curvilinear vascular probe of an echo machine is used to identify the flow in the distal femoral artery of the lower limb...

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...

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is widely used in treatment of decompensated heart failure. Our aim was to investigate its effects on regional perfusion and tissue oxygenation with respect to extracorporeal blood flow (EBF). In five swine, decompensated low-output chronic heart failure was induced by long-term rapid ventricular pacing. Subsequently, VA ECMO was introduced and left ventricular (LV) volume, aortic blood pressure, regional arterial flow and tissue oxygenation were continuously recorded at different levels of EBF...

OBJECTIVE: Although patients exercise greater autonomy than in the past, and shared decision making is promoted as the preferred model for doctor-patient engagement, tensions still exist in clinical practice about the primary locus of decision-making authority for complex, scarce, and resource-intensive medical therapies: patients and their surrogates, or physicians. We assessed physicians' attitudes toward decisional authority for adult venoarterial extracorporeal membrane oxygenation (VA-ECMO), hypothesizing they would favor a medical locus...

As new technologies develop, new ethical paradigms may be needed. This article considers several examples, such as stopping venoarterial extracorporeal membrane oxygenation (VA-ECMO), treating patients who are in a locked-in-like state who have awareness, purposefully deceiving patients who have dementia, meeting the needs of transgender persons, showing loved ones patients' wounds, and doing research on controlled substances. I suggest that clinicians should identify the practices underlying their value assumptions so they can alter their assumptions when this might improve the care they offer to their patients...

Venoarterial extracorporeal membrane oxygenation (VA ECMO) has become an indispensable treatment option for adult cardiothoracic patients experiencing acute refractory cardiogenic shock. VA ECMO is not without inherent complications as in-hospital mortality has ranged from 45% to 65% (1-3). Intracardiac thrombosis (ICT) is a rare but life-threatening complication associated with VA ECMO. VA ECMO cases complicated by ICT were searched for using the MEDLINE (PubMed and OVID), Society of Cardiovascular Anesthesiology Headquarters, and Google Scholar databases...

Extracorporeal membrane oxygenation (ECMO) is an accepted treatment modality for life support refractory to conventional efforts in neonates with complex congenital heart lesions. Cannulation for ECMO can be accomplished by venovenous (VV) access where patients receive primarily respiratory support or venoarterial (VA) access which provides complete cardiopulmonary support. VV ECMO delivered by a single-vessel cannulation with a dual-chamber venous cannula allows for respiratory support while the patient remains dependent upon intrinsic cardiac function to support hemodynamics...

Background Patients undergoing transcatheter aortic valve replacement can experience severe perioperative complications leading to hemodynamic instability and death. Venoarterial extracorporeal membrane oxygenation can be used to provide cardiorespiratory support during this time. Methods From 2012 to 2015, of 247 patients who underwent transcatheter aortic valve replacement, 6 (2.42%) required extracorporeal membrane oxygenation support. Their mean age was 82 ± 7.4 years, mean Society of Thoracic Surgeons score was 9...

PURPOSE OF REVIEW: Extracorporeal respiratory support in patients with acute respiratory distress syndrome is applied either as rescue maneuver for life-threatening hypoxemia or as a tool to reduce the harm of mechanical ventilation. Depending on the blood and gas flow, extracorporeal support may completely substitute the natural lung as a gas exchanger (high-flow venovenous bypass) or reduce the need for mechanical ventilation, enabling the removal of a fraction of the metabolically produced CO2...

BACKGROUND: Pheochromocytoma, a rare catecholamine-producing tumor, might provoke stress-induced Takotsubo-like cardiomyopathy and severe cardiogenic shock. Because venoarterial-extracorporeal membrane oxygenation (VA-ECMO) rescue of pheochromocytoma-induced refractory cardiogenic shock has rarely been reported, we reviewed our ICU patients' presentations and outcomes. METHODS: All pheochromocytoma-induced refractory cardiogenic shock cases managed with VA-ECMO (January 2007-March 2015) were prospectively included and reviewed...

We conducted a meta-analysis to provide the survival rates for pediatric patients hospitalized with fulminant myocarditis requiring ECMO. The literature search was conducted using Embase, PubMed, MEDLINE and Elsevier for studies published before April 1, 2016. We focus on survival rates for pediatric patients hospitalized with fulminant myocarditis requiring ECMO, and studies that reported only on adult patients were excluded. Summary of the survival rates was obtained using fixed-effect or random-effect meta-analysis which determined by I (2)...
