Waldenström's Macroglobulinemia (WM) is a rare lymphoma caused by the overproduction of immunoglobulin M (IgM). The elevated level of IgM causes serum hyperviscosity, cold agglutinins, and cryoglobulinemia. Anemia is also present because of impaired production of erythrocytes. For these reasons, placing a patient with WM on cardiopulmonary bypass (CPB) requires careful preparation. In this case, the patient was a 73-year-old male with known Waldenström's disease who required coronary artery bypass graft surgery...

Sickle cell disorders are associated with increased risk of sickling and vaso-occlusive complications when undergoing cardiopulmonary bypass (CPB) surgery. Monitoring of certain parameters such as venous and arterial oxygen content, hematocrit, acid base homeostasis, and body temperature are required for a superior outcome. Furthermore, perioperative exchange transfusion has a positive effect on the outcome of surgery and on the survival of patients undergoing heart surgery. Avoiding intraoperative hypoxia and hypothermia, and minimizing hemoglobin S (HbS) and hemoglobin C (HbC) levels with exchange transfusion make bypass surgery relatively safe with enhanced outcomes in these cases...

Many blood conservation techniques and strategies have been implemented to aid in decreasing the use of allogenic blood utilization during pediatric cardiothoracic surgery. Use of techniques, such as acute normovolemic hemodilution, retrograde autologous prime, venous autologous prime, and autotransfuion, may lead to a decrease in the need for allogenic blood products. Autotransfusion has become a standard of care for all cardiothoracic surgical procedures requiring cardiopulmonary bypass (CPB). Although widely used, there is still debate over which wash solution will produce the most physiologically normal autotransfusion product...

Although the potential for the utilization of electronic perfusion data (EPD) from proprietary software to facilitate the understanding and improvement of cardiopulmonary bypass (CPB) has been recognized, the generalizability of previous reports of EPD integration are limited by superceded software or lack of sufficient detail for reproducibility. To date, the Australian and New Zealand Collaborative Perfusion Registry (ANZCPR) is the only multicentre perfusion registry to have reported the integration of EPD...

Extracorporeal membrane oxygenation (ECMO) is often managed using minimal anticoagulation. This can make the circuitry susceptible to thrombosis. The ECMO cannula may be particularly vulnerable to thrombosis if flow is interrupted for an undetermined but prolonged period of time. Therefore, under conditions where cannula blood flow stasis may be prolonged and flashing, the cannulae is not an option (e.g., air in circuit) it is imperative to have an emergency plan available, which can be rapidly implemented that will provide a means of cannula patency preservation...

Hemolysis is a known consequence of extracorporeal membrane oxygenation (ECMO) resulting from shear force within the different components of the extracorporeal circuit. The primary aim of this study was to evaluate the EOS PMP™ oxygenator for generation of plasma free hemoglobin (PfHg) over 24 hours at nominal operating range flow rates. The EOS ECMO™ (LivaNova, Inc.; formerly Sorin, Arvada, CO) is equipped with a plasma tight polymethylpentene (PMP) hollow fiber oxygenator. We hypothesized that PfHg generation would be elevated in circuits with higher flow rates, because of the significant pressure drop across the oxygenator according to manufacturer provided flow charts...

Despite the ubiquitous use of cardioplegia in cardiac surgery, there is a lack of agreement on various aspects of cardioplegia practice. To discover current cardioplegia practices throughout the world, we undertook a global survey to document contemporary cardiopulmonary bypass practices. A 16-question, Internet-based survey was distributed by regional specialist societies, targeting adult cardiac anesthesiologists. Ten questions concerned caseload and cardioplegia practices, the remaining questions examined anticoagulation and pump-priming practices...

Acquired von Willebrand syndrome (VWS) due to loss of high-molecular-weight multimers (HMWMs) has been reported with longer term mechanical devices and is associated with mucosal bleeding, a primary hemostasis type of bleeding. However, little is known whether a similar defect occurs in patients with short-term mechanical circulatory support (STMCS) devices. We reviewed von Willebrand factor (VWF) profiles in patients with STMCS devices who underwent VWS workup from December 2015 to March 2017 at an academic quaternary care hospital...

Respiratory failure associated with hematopoietic stem cell transplantation (HSCT) has been considered a contraindication for use of extracorporeal membrane oxygenation (ECMO) at many centers. We describe a child with neuroblastoma and hypoxemic respiratory failure following HSCT who was successfully managed with veno-venous (VV) ECMO. The patient was an 18-month-old female with high-risk neuroblastoma status post tumor resection, chemotherapy, autologous HSCT, and primary site radiation. On day 113 posttransplant while receiving maintenance immunotherapy, she had an acute respiratory decompensation because of rhinovirus, aspiration pneumonia, and capillary leak syndrome...

Indications for extra corporeal membrane oxygenation (ECMO) have expanded in recent years, and it has become an invaluable tool in the care of adult patients in severe cardiogenic shock or respiratory failure. Understanding the physiologic effect of ECMO has also further developed, allowing for improvements in the management of the potential morbidities associated with this technology. Here, we present a case of acute bowel ischemia that developed while the patient was on central venoarterial ECMO.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is an invaluable rescue therapy for patients suffering from cardiopulmonary arrest, but it is not without its drawbacks. There are cases where patients recover their cardiac function, yet they fail to wean to mechanical conventional ventilation (MCV). The use of high-frequency percussive ventilation (HFPV) has been described in patients with acute respiratory failure (RF) who fail MCV. We describe our experience with five patients who underwent VA-ECMO for cardiopulmonary arrest who were successfully weaned from VA-ECMO with HFPV after failure to wean with MCV...

Myocardial protection during cardiac surgery is a multifaceted process that is structured to limit injury and preserve function. Evolving techniques use solutions with varying constituents that enter the systemic circulation and alter intrinsic systemic concentrations. This study compared two distinct cardioplegia solutions on affecting intraoperative glucose levels. Data were abstracted from a multi-institutional perfusion registry, including a total of 1,188 propensity-matched cases performed from January through October 2016, at 17 cardiac surgical centers across the United States in which both del Nido and 4:1 cardioplegia were used during the study period...

Unfractionated heparin is the mainstay of anticoagulation during cardiac surgery on cardiopulmonary bypass (CPB) due to its low cost, quick onset, and ease of reversal. Since over 30 years, the activated clotting time (ACT) has been used to assess the level of heparin activity both before and after CPB. We compared two different methods of measuring the ACT: i-STAT, which uses amperometric detection of thrombin cleavage, and Hemochron Jr, which is based on detecting viscoelastic changes in blood. We included 402 patients from three institutions (Papworth Hospital, Cambridge, UK; Groote Schuur, Cape Town, South Africa; University Hospital Basel, Basel, Switzerland) undergoing elective cardiac surgery on CPB in our study...

Anticoagulation during infant-pediatric extracorporeal life support (ECLS) has been a topic of study for many years, but management of anticoagulation is still only partially understood. Adequate anticoagulation during ECLS is imperative for successful outcomes and understanding the individual variables that play part is crucial for properly implementing anticoagulation management strategies. The purpose of our study was to compare the relationships between the variables of activated partial thromboplastin time (aPTT), activated clotting time, international normalized ratio, bleeding, thrombus formation, kaolin + heparinase thromboelastograph alpha angle, kaolin thromboelastograph reaction time (KTEG R-time), heparin dose rates (HDR), antithrombin (AT), anti-Xa, bivalirudin dose rate, argatroban dose rate, interventions, and transfusions...

A pilot study to measure and compare blood and urine microRNAs miR-210 and miR-16 in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) and off-pump coronary artery bypass grafting surgery. Frequent serial blood and urine samples were taken from patients undergoing cardiac surgery with CPB (n = 10) and undergoing off-pump cardiac surgery (n = 5) before, during, and after surgery. Circulating miR-210 and miR-16 levels were determined by relative quantification real-time polymerase chain reaction...
