OBJECTIVE: Use of deep hypothermic low-flow (DHLF) cardiopulmonary bypass (CPB) has been associated with higher fluid loading than the use of deep hypothermia circulatory arrest (DHCA). We evaluated whether these perfusion strategies influenced fluid extravasation rates and edema generation differently per-operatively. MATERIALS AND METHODS: Twelve anesthetized pigs, randomly allocated to DHLF (n = 6) or DHCA (n = 6), underwent 2.5 hours CPB with cooling to 20°C for 30 minutes (min), followed by 30 min arrested circulation (DHCA) or 30 min low-flow circulation (DHLF) before 90 min rewarming to normothermia...

Giant pulmonary bullae are rare and surgical management of patients with severe emphysema and advanced chronic obstructive lung disease (COPD) presenting with giant bullae can be very challenging. Previously, perioperative, two-site, high-flow, veno-venous extracorporeal membrane oxygenation (ECMO) was successfully utilized during giant bulla resection. Here we report the perioperative application of single-site, low-flow extracorporeal CO2 removal (ECCO2R) for minimally invasive thoracoscopic giant bulla resection...

INTRODUCTION: A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering...

INTRODUCTION: Interaction of blood with a cardiopulmonary bypass (CPB) circuit activates the coagulation-fibrinolysis, complement and kinin-kallikrein systems that are mainly supported by proteases and their inhibitors. METHODS: Biocompatibility of a new polymer-coated (SEC-coated) CPB circuit was globally evaluated and compared with that of a non-coated CPB circuit by quantitative proteomics, using isobaric tags for relative and absolute quantification labeling tandem mass spectrometry...

BACKGROUND: Continuous bilateral thoracic paravertebral blockade has been used for analgesia after cardiac surgery, but its efficacy has never been formally tested. METHOD: Fifty adult patients were enrolled in a double-blind, randomised, controlled study of continuous bilateral thoracic paravertebral infusion of 0.5% lidocaine (1 mg.kg(-1).hr(-1)) for analgesia after coronary surgery. Control patients received a subcutaneous infusion of lidocaine at the same rate through catheters inserted at the same locations as the study group...

INTRODUCTION: When applying a blood-conserving approach in paediatric cardiac surgery with the aim of reducing the transfusion of homologous blood products, the decision to use blood or blood-free priming of the cardiopulmonary bypass (CPB) circuit is often based on the predicted haemoglobin concentration (Hb) as derived from the pre-CPB Hb, the prime volume and the estimated blood volume. We assessed the accuracy of this approach and whether it may be improved by using more sophisticated methods of estimating the blood volume...

Inferior vena cava abnormalities or agenesis had to be suspected in front of technical difficulties during venous catheterization. In the setting of extracorporeal life support and during chest compressions, femoral vascular access is the easiest, most efficient and, perhaps, the first approach for a successful extracorporeal cardiopulmonary resuscitation. In the case of inferior vena cava agenesis leading to cannulation failure and/or complications, the use of the right internal jugular vein for salvage venous cannulation is a potential life-saving strategy...

INTRODUCTION: Lung dysfunction following cardiac surgery is currently viewed as the consequence of atelectasis and lung injury. While the mechanism of atelectasis has been largely detailed, the pathogenesis of lung injury after cardiopulmonary bypass is still unclear. Based upon clinical and experimental studies, we hypothesized that lungs could be injured through a mechanical phenomenon. METHODS: We recorded pulmonary compliance at six key moments of a heart operation in 62 adult patients undergoing elective cardiac surgery...

INTRODUCTION: Safety concerns have been one of the main reasons opposing a wider acceptance of minimal invasive extracorporeal circuits (MiECC). Following an extensive experience and a multitude of modifications, we have set out to employ a modular MiECC as a universal extracorporeal circuit. METHODS: A total of 129 cardiac surgical procedures were performed by a single surgeon in 2013. Excluding procedures done under circulatory arrest or with the potential need of such, the MiECC was utilized in almost 90% of surgeries...

We report on a 32-year-old male patient with acute left-hemispheric stroke caused by embolism due to infective endocarditis affected from the HACEK group. Additionally, atypical findings from the transesophageal echocardiography (TEE) which showed fluttering structures belonging to the papillary muscle could be proven as infectious agents with the help of a glucose positron emission tomography (PET) scan. TEE controls showed increasing vegetation involving the mitral valve so that surgery became necessary. The current work reflects, in detail, the emergent clinical course of this young patient, suffering from both an unusual localization and an infrequent cause of endocarditis and focuses on an actual view to the literature...

BACKGROUND: Cardiopulmonary bypass is thought to propagate a global systemic response through contact with the non-physiological surfaces of the extracorporeal circuit, leading to the stimulation of leukocytes, their adherence to endothelial cells and the release of cytotoxic molecules. This, in turn, has been shown to accelerate pulmonary injury. This study tested a new leukocyte-filtration system (RemoweLL) against a conventional system with no leukocyte-depleting capacity to determine the efficacy of the filtration system and its effects on pulmonary function...

BACKGROUND: Development of a high-fidelity cardiac surgery simulator (CSS) requires integration of a heart model with a mock cardiopulmonary bypass (CPB) circuit that can provide feedback to mimic the pathophysiology of cardiac surgery. However, the cost of commercially available simulators precludes regular use. We describe steps in the construction of a high-fidelity CSS that integrates a pulsatile paracorporeal ventricular-assist device (Pulse-VAD) and a commercially available CPB simulator...

INTRODUCTION: The aim of this study was to assess the relationships among cardiac output, extracorporeal blood flow, cannulation site, right (RCa) and left carotid (LCa), celiac (Ca) and renal artery (Ra) flows during extracorporeal circulation. METHODS: A mock circulatory circuit was assembled, based on a compliant anatomical aortic model. The ascending aorta, right subclavian and femoral artery cannulations were created and flow was provided by a centrifugal pump (Cp); cardiac output was provided by a roller pump (Rp)...

INTRODUCTION: We report a case of renal replacement therapy (RRT) during extracorporeal membrane oxygenation (ECMO) via a single venous access and analyze the feasibility of transpulmonary thermodilution (TPTD) for hemodynamic monitoring. CASE REPORT: ECMO and RRT connected into the ECMO-extracorporeal circuit were performed via a single venous access because of multiple venous thromboses. An indicator for TPTD and pulse contour analysis (PCA) was applied into the central venous catheter (CVC) placed in the right vena jugularis...

BACKGROUND: Acute kidney injury (AKI) following cardiopulmonary bypass affects 5% of patients, representing significant postoperative morbidity and mortality. Animal models have shown an increased uptake of lipid microemboli (LME) into the renal vasculature, potentially indicating ischaemic causation. This study tested a new lipid filtration system (RemoweLL) against a conventional system with no lipid-depleting capacity to determine the efficacy of the filtration system and its effects on renal function...
