The patient was a 32-year-old woman who presented with infertility secondary to uterine didelphys. Hysteroscopic metroplasty was chosen as the corrective surgical procedure for this anatomical defect. During the surgical repair, the patient developed a massive air embolism (MAE) leading to hypotension, arrhythmia, and cardiogenic shock. Resuscitation was started by placing the patient in the right-side up position, and emplacement of central venous catheter, but it was unsuccessful. The decision was then made to bypass the patient's cardiopulmonary system to effectively treat the MAE...

Amniotic fluid embolism (AFE) is an unusual cause of life threatening peri partum hemorrhage (PPH). AFE resuscitation is often associated with renal and respiratory insufficiency, and a coagulopathy similar to disseminated intravascular coagulation (DIC). Resuscitation requires immediate recognition and limited use of crystalloid. We present a case of PPH caused by AFE with resultant cardiac arrest, renal and respiratory failure, and DIC-like coagulopathy, whose successful resuscitation was guided by perfusionist-directed serial thromboelastography (TEG)...

Uncertainty exists regarding the optimal strategy for the management of anemia in the setting of cardiac surgery. We sought to improve our understanding of the role of intra-operative hematocrit (HCT) and transfusions on peri-operative outcomes following cardiac surgery. A total of 18,886 patients undergoing on-pump cardiac surgery were identified from a multi-institutional registry including surgical and perfusion data. Patients were divided into four groups based on their intra-operative nadir HCT (<21 or ≥21) and whether or not they received intra-operative red blood cell (+RBC or -RBC) transfusions...

Presently, there exists no published valid and reliable salary study of clinical perfusionists. The objective of the 2015 Perfusionist Salary Study was to gather verifiable employee information to determine current compensation market rates (salary averages) of clinical perfusionists working in the United States. A salary survey was conducted between April 2015 and March 2016. The survey required perfusionists to answer questions about work volume, scheduling, and employer-paid compensation including benefits...

This study assesses the effects of transfusion of autologous or allogeneic blood on cerebral and tissue oxygenation during spinal surgery. Packed red blood cell transfusions are indicated to improve oxygen delivery to tissues. There are limited data demonstrating changes in tissue oxygenation with blood administration. Tissue (deltoid) and cerebral oxygenation were monitored using near-infrared spectroscopy during spinal surgery in patients. As indicated, cell saver or allogeneic blood was administered. Tissue and cerebral oxygenation were recorded before and after transfusion...

Autotransfusion protocols often use the use of costly filters, such as leukocyte-depleting filters (LDFs), to minimize reinfusion of activated leukocytes and inflammatory mediators associated with reperfusion injury (RI). LDFs are used extensively in hospital settings; however, they represent an additional capital expenditure for hospitals, as well as a constraint on the reinfusion rate of blood products for health-care providers. We compared a commonly used LDF to a novel centrifugation method employing a widely used cell salvage device...

REVIEW
Brittney Williams, Wendy Bernstein
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...

Over the years, there has been a growing recognition of the potential negative sequelae of allogeneic blood products on postoperative outcomes following cardiac surgery. In addition, followers of the Jehovah's Witness (JW) faith have a religious restriction against receiving blood or blood components. Advances in perioperative care, cardiopulmonary bypass (CPB), and surgical technique have minimized the need for allogeneic blood products. Specific blood conservation strategies include maximizing the preoperative hematocrit and coagulation function as well as intraoperative strategies, such as acute normovolemic hemodilution and adjustments of the technique of CPB...

Seizures following cardiopulmonary bypass are an immediate and alarming indication that a neurologic event has occurred. A case report of a 67-year-old man undergoing aortic valve surgery who unexpectedly experiences seizures following cardiopulmonary bypass is outlined. Possible contributing factors including atheromatous disease in the aorta, low cerebral perfusion pressures, an open-chamber procedure, and the use of tranexamic acid are identified.

Gaseous microemboli (GME) are an abnormal physiological occurrence during cardiopulmonary bypass and extracorporeal membrane oxygenation (ECMO). Several studies have correlated negative sequelae with exposure to increased amounts of GME. Hypobaric oxygenation is effective at eliminating GME in hollow-fiber microporous membrane oxygenators. However, hollow-fiber diffusion membrane oxygenators, which are commonly used for ECMO, have yet to be validated. The purpose of this study was to determine if hypobaric oxygenation, compared against normobaric oxygenation, can reduce introduced GME when used on diffusion membrane oxygenators...

Open aortic arch replacement is a complex and challenging procedure, especially in post dissection aneurysms and in redo procedures after previous surgery of the ascending aorta or aortic root. We report our experience with the simultaneous selective perfusion of heart, brain, and remaining body to ensure optimal perfusion and to minimize perfusion-related risks during these procedures. We used a specially configured heart-lung machine with a centrifugal pump as arterial pump and an additional roller pump for the selective cerebral perfusion...

Competitive flows syndrome result in severe regional hypoxemia when the deoxygenated flow from the native left ventricle (LV) competes with oxygenated flow from extracorporeal life support (ECLS) pump with potentially severe consequences for the cerebral and coronary circulations. Fast correction of hypoxemia could be obtained by decreasing native LV flow by infusion of a short-acting beta-blocker (esmolol). Our purpose was to retrospectively review the efficacy of esmolol in this situation and hypothesize on the potential mechanisms of action and the associated risks...

#17
Daniel P Herbst
The process of microbubble filtration from blood is complex and highly dependent on the forces of flow and buoyancy. To protect the patient from air emboli, arterial-line filters commonly use a micropore screen, a large volume housing with purpose-built shape, and a purge port to trap, separate, and remove circulating microbubbles. Although it has been proposed that an insufficient buoyancy force renders the purge port ineffective at removing microbubbles smaller than 500 μm, this research attempts to investigate the purge flow of an arterial-line filter to better understand the microbubble removal function in a typical radial filter design...

REVIEW
Donald S Likosky, Timothy A Dickinson, Theron A Paugh
Cardiac surgery accounts for between 15% and 20% of all blood product utilization in the United States. A body of literature suggests that patients who are exposed to even small quantities of blood have an increased risk of morbidity and mortality, even after adjusting for pre-operative risk. Despite this body of literature supporting a restrictive blood management strategy, wide variability in transfusion rates exist across institutions. Recent blood management guidelines have shed light on a number of potentially promising blood management strategies, including acute normovolemic hemodilution (ANH) and retrograde autologous priming (RAP)...
