AIMS: A successful cephalosomatic anastomosis ("head transplant") requires, among others, the ability to control long-term immune rejection and avoidance of ischemic events during the head transference phase. We developed a bicephalic model of head transplantation to study these aspects. METHODS AND RESULTS: The thoracic aorta and superior vena cava of a donor rat were anastomosed with the carotid artery and extracorporeal veins of a recipient rat by vascular grafts...

BACKGROUND: Glutamine is the most abundant free amino acid in the body. It modulates immune cell function and is an important energy substrate for cells in critically ill patients. Reduction of injury cardiac markers had been observed in patients receiving intravenous glutamine and in a pilot study with oral glutamine. The aim of this study was to analyze the effect of preoperative oral supplementation of glutamine on postoperative serum levels of cardiac injury markers. METHODS: A randomized clinical trial was performed in 28 Mexican patients with ischemic heart disease who underwent cardiopulmonary bypass with extracorporeal circulation...

BACKGROUND: Living donor liver transplantation has shorter cold ischemia time, less preservative volume and lower metabolic load compared to transplantation from deceased donors. We investigated the impact of rinsing the graft contents into the systemic circulation on operative course and post-operative outcomes. PATIENTS AND METHODS: Donors had right hepatectomy and grafts were preserved with cold Histidine-Tryptophan-Ketoglutarate solution. On ending portal vein anastomosis, grafts were flushed by patient's portal blood; either through incompletely anastomosed hepatic vein (Extracorporeal Rinse group, EcRg, n=40) or into systemic circulation (Circulatory Rinse group, CRg, n=40)...

Extracorporeal circulation has led to a great development in cardiovascular surgery during the last five decades. Its time-proven efficacy and safety have made on-pump coronary artery bypass grafting (CABG) the gold standard method of surgical revascularization. However, coronary revascularization on cardiopulmonary bypass and the accompanying aortic manipulation are related to plenty of deleterious complications. Therefore, off-pump CABG surgery was established to avoid complications. Nevertheless, despite the initial enthusiasm on this technique, only 20% of myocardial revascularization procedures worldwide are performed off-pump...

BACKGROUND: Coronary artery bypass surgery can be performed without (Off-Pump) or with cardiopulmonary bypass (On-Pump). Extracorporeal circulation and cardioplegic arrest may cause alterations in the plasma metabolome. We assessed metabolomic changes in patients undergoing On-Pump or Off-Pump coronary artery bypass surgery. METHODS: We assessed five analyte classes (41 acylcarnitines, 14 amino acids, 92 glycerophospholipids, 15 sphingolipids, sugars, lactate) using a mass-spectrometry-based kit (Biocrates AbsoluteIDQ® p150) in paired arterial and coronary sinus blood obtained from 10 consecutive On-Pump and 10 Off-Pump patients...

BACKGROUND: Performing advanced cardiac life support (ACLS) in the cardiac catheterization laboratory (CCL) is challenging. Mechanical chest compression (MCC) devices deliver compressions in a small space, allowing for simultaneous percutaneous coronary intervention and reduced radiation exposure to rescuers. In refractory cases, MCC devices allow rescuers to initiate percutaneous mechanical circulatory support (MCS) and extracorporeal life support (ECLS) during resuscitation. This study sought to assess the efficacy and safety of MCC when compared to manual compressions in the CCL...

Cardiac surgery with extracorporeal circulation is characterized by different degrees of myocardial ischemia/reperfusion, which is often associated with postoperative atrial fibrillation (POAF). We have previously shown that a novel preventive therapy based on the reinforcement of the antioxidant system using omega-3 fatty acids plus antioxidant vitamin supplementation applied to patients undergoing cardiac surgery reduces POAF occurrence. We hypothesized that oxidative stress and nitrosative stress are involved in the development of an arrhythmogenic substrate by their effect on connexins (Cx40, Cx43 and Cx45) abundance and distribution pattern...

Complications due to pump thrombus remain the weak point of mechanical circulatory support (MCS), such as the use of a left ventricular assist device (LVAD) or extracorporeal membrane oxygenation, leading to poor outcomes. Hyperspectral imaging (HSI) is an effective imaging method using a hyperspectral (HS) camera, which comprises a spectrophotometer and a charge-coupled device camera to discriminate thrombus from whole blood. Animal experiments were conducted to analyze dynamic imaging of thrombus inside a prototype of a hydrodynamically levitated centrifugal blood pump using an HSI system...

PURPOSE OF REVIEW: Despite a significant increase in the utilization of donors after circulatory death (DCD), the number of organs recovered and their function are largely inferior to those from donors after brain death. This review summarizes recent advances in in-situ normothermic regional perfusion of DCD organs prior to procurement. RECENT FINDINGS: The combination of warm and cold ischemia in DCD donation are detrimental to organ function. As a consequence, the acceptance criteria are far more restrictive and many organs are discarded...

This paper presents a decentralized safety concept for networked intensive care setups, for which a decentralized network of sensors and actuators is realized by embedded microcontroller nodes. It is evaluated for up to eleven medical devices in a setup for automated acute respiratory distress syndrome (ARDS) therapy. In this contribution we highlight a blood pump supervision as exemplary safety measure, which allows a reliable bubble detection in an extracorporeal blood circulation. The approach is validated with data of animal experiments including 35 bubbles with a size between 0...

BACKGROUND: Ventilation with low tidal volume and airway pressure results in a survival benefit in ARDS patients. Previous research suggests that avoiding mechanical ventilation altogether may be beneficial in some cases of respiratory failure. Our hypothesis was that low flow veno-venous extracorporeal CO2 removal (ECCO2R) enables maintenance of a lung protective ventilation strategy or awake spontaneous ventilation despite severe hypercapnic respiratory failure (HRF). METHODS: Twenty patients with HRF were investigated while mechanically ventilated (n=14) or breathing spontaneously close to respiratory exhaustion (n=6)...

Extracorporeal circulation is an invaluable tool in lung transplantation. Over the past years, an increasing number of centers changed their standard for intraoperative extracorporeal circulation from cardiopulmonary bypass to extracorporeal membrane oxygenation - with differing results. This meta-analysis reviews the existing evidence.An online literature research on Medline, Embase, and Pubmed has been performed. Two persons independently judged the papers using the ACROBAT-NRSI tool of the Cochrane collaboration...

PURPOSE: Patients undergoing cardiac surgery with extracorporeal circulation (ECC) frequently present haemorrhages as a complication associated with high morbidity and mortality. One of the factors that influences this risk is the volume of blood infused during surgery. The objective of this study was to determine the optimal volume of autologous blood that can be processed during cardiac surgery with ECC. We also determined the number of salvaged red blood cells to be reinfused into the patient in order to minimize the risk of haemorrhage in the postoperative period...

Movement disorders following heart surgery are very unusual. Post-pump chorea is mainly a pediatric complication of heart surgery, typically manifesting after a latent period of normality and is usually related with long extracorporeal circulation time and deep hypothermia. We report a 73-year-old woman, without risk factors predisposing to paroxysmal movement disorders, presenting acute choreoathetoid movements 5 days after aortic valvular replacement with normal extracorporeal circulation time and perioperative normothermia...

BACKGROUND: Recent studies have shown that fibroblast growth factor-23 (FGF-23) is elevated not only in chronic kidney disease (CKD), but also in acute illnesses such as acute kidney injury, septic shock, and acute heart failure. FGF-23 would be not only a simple biomarker but also a direct toxic factor in acute illness. Therefore, lowering circulating FGF-23 levels in clinical practice would be an exciting and valuable interventional strategy. Continuous hemodiafiltration (CHDF) is often performed for the treatment of the aforementioned acute illnesses...
