Vasoplegic syndrome during heart transplantation: A systematic review and meta-analysis.

BACKGROUND: Vasoplegic syndrome (VS) is a common occurrence during heart transplantation (HT). It currently lacks a uniform definition between transplant centers, and its pathophysiology and treatment remain enigmatic. This systematic review summarizes the available published clinical data regarding VS during HT. METHODS: We searched databases for all published reports on VS during HT. Data collected included the incidence of VS in the HT population, patient and intraoperative characteristics, and postoperative outcomes. RESULTS: Twenty-two publications were included in this review. The prevalence of VS during HT was 28.72% (95% confidence interval: 27.37%, 30.10%). Factors associated with VS included male sex, higher body mass index, hypothyroidism, pre-HT left ventricular assist device or venoarterial extracorporeal membrane oxygenation (VA-ECMO), pre-HT calcium channel blocker or amiodarone usage, longer cardiopulmonary bypass time, and higher blood product transfusion requirement. Patients who developed VS were more likely to require postoperative VA-ECMO support, renal replacement therapy, reoperation for bleeding, longer mechanical ventilation, and a greater 30-day and 1-year mortality. CONCLUSIONS: The results of our systematic review are an initial step for providing clinicians with data that can help identify high-risk patients and avenues for potential risk mitigation. Establishing guidelines that officially define VS will aid in the precise diagnosis of these patients during HT and guide treatment. Future studies of treatment strategies for refractory VS are needed in this high-risk patient population.

Evaluating the Impact of Operative Team Familiarity on Cardiac Surgery Outcomes: A Retrospective Cohort Study of Medicare Beneficiaries.

OBJECTIVE: To associate surgeon-anesthesiologist team familiarity (TF) with cardiac surgery outcomes. BACKGROUND: TF, a measure of repeated team member collaborations, has been associated with improved operative efficiency; however, examination of its relationship to clinical outcomes has been limited. METHODS: This retrospective cohort study included Medicare beneficiaries undergoing coronary artery bypass grafting (CABG), surgical aortic valve replacement (SAVR), or both (CABG+SAVR) between January 1, 2017, and September 30, 2018. TF was defined as the number of shared procedures between the cardiac surgeon and anesthesiologist within 6 months of each operation. Primary outcomes were 30- and 90-day mortality, composite morbidity, and 30-day mortality or composite morbidity, assessed before and after risk adjustment using multivariable logistic regression. RESULTS: The cohort included 113,020 patients (84,397 CABG; 15,939 SAVR; 12,684 CABG+SAVR). Surgeon-anesthesiologist dyads in the highest [31631 patients, TF median (interquartile range)=8 (6, 11)] and lowest [44,307 patients, TF=0 (0, 1)] TF terciles were termed familiar and unfamiliar, respectively. The rates of observed outcomes were lower among familiar versus unfamiliar teams: 30-day mortality (2.8% vs 3.1%, P =0.001), 90-day mortality (4.2% vs 4.5%, P =0.023), composite morbidity (57.4% vs 60.6%, P <0.001), and 30-day mortality or composite morbidity (57.9% vs 61.1%, P <0.001). Familiar teams had lower overall risk-adjusted odds of 30-day mortality or composite morbidity [adjusted odds ratio (aOR) 0.894 (0.868, 0.922), P <0.001], and for SAVR significantly lower 30-day mortality [aOR 0.724 (0.547, 0.959), P =0.024], 90-day mortality [aOR 0.779 (0.620, 0.978), P =0.031], and 30-day mortality or composite morbidity [aOR 0.856 (0.791, 0.927), P <0.001]. CONCLUSIONS: Given its relationship with improved 30-day cardiac surgical outcomes, increasing TF should be considered among strategies to advance patient outcomes.

Prevention of drug diversion and substance use disorders among anesthesiologists: a narrative review

Abstract Diversion of substances from the care of the intended patient is a significant problem in healthcare. Patients are harmed by the undertreatment of pain and suffering, transmission of disease, as well as the risk associated with impaired vigilance. Healthcare providers may be harmed by the physical and mental impact of their addictions. Healthcare systems are placed in jeopardy by the legal impact associated with illegal routes of drug release including sanction and financial liability and loss of public trust. Healthcare institutions have implemented many measures to reduce diversion from the perioperative area. These efforts include education, medical record surveillance, automated medication dispensing systems, urine drug testing, substance waste management systems, and drug diversion prevention teams. This narrative review evaluates strengths, weaknesses, and effectiveness of these systems and provides recommendations for leaders and care providers.

Invasive Pressure Monitors: Leveling the Playing Field.

Invasive pressure monitors are ubiquitous in cardiothoracic and vascular anesthesia. This technology allows beat-to-beat assessment of central venous, pulmonary, and arterial blood pressures during surgery, procedural interventions, and critical care. Education is commonly focused on the procedural aspects and the complications associated with the initial placement of these monitors without instruction on the technical concepts required for obtaining accurate data. Anesthesiologists must understand the fundamental concepts on which measurements are made to effectively use invasive pressure monitors, including pulmonary artery catheters, central venous catheters, intra-arterial catheters, external ventricular drains, and spinal or lumbar drains. This review will address important gaps in knowledge surrounding leveling and zeroing of invasive pressure monitors, emphasizing the impact of varied practice patterns on patient care.

Barriers to recovery for medical professionals: Assessing financial support through a survey of Physician Health Programs.

BACKGROUND AND OBJECTIVES: There is increasing focus on physician burnout, psychiatric problems, and substance use disorders. Costs of recovery for physicians enrolled in Physician Health Programs (PHPs) remain unexamined with little known regarding funding resources. We sought to elucidate perceived costs of recovery from impairing conditions and highlight resources for financial strain. METHODS: This survey study was distributed by the Federation of State Physician Health Organizations via e-mail to 50 PHPs in 2021. Questions assessed perceptions of costs and ability to pay for recommended evaluation, treatment, and monitoring. Questions also assessed limitation of engagement due to financial concerns, and availability of financial resources. RESULTS: Complete responses were received from 40 of 50 eligible PHPs. The majority (78%) of responding PHPs assessed ability to pay at initial intake evaluation. There is notable financial strain on physicians, particularly those earliest in training, to pay for services. DISCUSSION AND CONCLUSIONS: PHPs are vital to physicians, especially physicians-in-training, as "safe haven programs." Methods to financially assist through PHPs included fee deferrals, sliding scale fees, and fee forgiveness. Health insurance, medical schools, and hospitals were able to provide additional assistance. SCIENTIFIC SIGNIFICANCE: Because burnout, mental health, and substance use disorders are high stakes amongst physicians, it is critical that access to PHPs is available, destigmatized, and affordable. Our paper focuses specifically on the financial cost of recovery, the financial burden placed on PHP participants, a topic lacking in the literature, and highlights remedies and vulnerable populations.

Factor V Deficiency (Owren's Disease) in a Patient at High Risk for Transfusion-Associated Circulatory Overload and Bleeding During Laser Lead Extraction.

Congenital factor V deficiency is an extremely rare abnormality and may be associated with significant bleeding as a result of trauma or surgery. Perioperative management primarily includes the administration of fresh frozen plasma to replace the deficient clotting factor. Acute administration of multiple blood products is a risk factor for transfusion-associated circulatory overload. Herein, the case of a 71-year-old man with an ejection fraction of 13% and a history of congenital factor V deficiency who was at risk for significant bleeding and transfusion-associated circulatory overload who underwent successful complex extraction of a right atrial pacing lead is reported.

Perioperative Outcomes of Thrombectomy Patients Using Venovenous Bypass and Suction Filtration With General Anesthesia.

OBJECTIVE: AngioVac (Angiodynamics, Latham, NY) is a novel drainage system that offers a less-invasive approach compared with open surgical thromboembolectomy to remove intracardiac and intravascular thrombotic and embolic material. For this study, the authors' single-center experience with patients undergoing thromboembolectomy using the AngioVac system was reviewed retrospectively to evaluate anesthetic management and postoperative complications. DESIGN: Retrospective, observational study. SETTING: Single institution, quaternary care hospital. PARTICIPANTS: The study comprised 20 consecutive patients whose treatment included the AngioVac between January 2016 and November 2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Twenty patients underwent AngioVac suction filtration. The mean age was 56 years, and women comprised 35% of the patient cohort. Indications for AngioVac suction filtration included deep venous thrombosis involving the inferior vena cava (n = 12 [60%]), right atrial mass/thrombus (n = 11 [55%]), right ventricular mass/thrombus (n = 3 [15%]), and pulmonary embolism(n = 2 [10%]). All patients required vasopressor support, and nine patients (45%) required blood transfusion during the procedure. There was no intraoperative death or cardiac arrest associated with the procedure. The 30-day mortality was zero, and in-hospital mortality was 5% (1/20). Significant postoperative complications occurred in 11/20 patients (55%). Postoperative left ventricular dysfunction (36% v 0%; p < 0.05), preoperative shock requiring vasopressors (36% v 0%; p < 0.05), postoperative blood transfusion (100% v 56%; p < 0.05), and having undergone recent surgery (64% v 11%; p < 0.05) were associated with increased odds of experiencing postoperative complications. CONCLUSIONS: The rate of intraoperative complication during AngioVac suction filtration is low, but vasopressors and blood transfusions often are required. Patients at increased risk of developing postoperative complications potentially can be identified as having undergone recent surgery, experiencing preoperative shock requiring vasopressors or postoperative left ventricular dysfunction, and requiring postoperative blood transfusion.

Implantable Cardioverter-Defibrillator Shock Delivered During Electroconvulsive Therapy Despite Magnet Application: A Case Report.

Electroconvulsive therapy (ECT) in a patient with an implantable cardioverter-defibrillator (ICD) presents challenges to anesthesiologists. We encountered a patient who received an inappropriate shock during ECT despite magnet application. The phenomenon provides insight into how ICDs work-how they can inappropriately detect ECT stimulation and how they deliver antitachycardia therapy. We illuminate issues related to using magnets, discuss risks associated with inappropriate ICD therapy, and provide guidance for ICD management during ECT.

Pulmonary Artery Catheter Thrombus in a Patient With Essential Thrombocytosis: A Case Report.

Essential thrombocytosis (ET) is a rare chronic myeloproliferative disorder characterized by elevated platelet counts. The management of patients with ET undergoing coronary artery bypass graft remains unclear. Often, patients who are deemed "high risk" for thrombotic events receive cytoreductive therapy before surgery, while patients deemed "low risk" do not receive cytoreductive therapy. Here, we present a case of a patient with ET with only a mild elevation in platelets deemed "low risk" for thrombotic complications who was found to have a small intracardiac thrombus around the pulmonary artery catheter before initiation of cardiopulmonary bypass.

Reducing the Incidence of Substance Use Disorders in Anesthesiology Residents: 13 Years of Comprehensive Urine Drug Screening.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: The incidence of substance use disorders in the United States among residents in anesthesiology is between 1% and 2%. A recent study reported that the incidence of substance use disorders in U.S. anesthesiology residents has been increasing. There are no reports of effective methods to prevent substance use disorder in residents. A comprehensive drug testing program including a random component may reduce the incidence of substance use disorders. METHODS: The authors initiated a comprehensive urine drug screening program of residents, fellows, faculty physicians, and certified nurse anesthetists. The authors performed 3,190 tests over 13 yr. The authors determined the incidence of substance use disorders among residents in our large anesthesiology residency program during the decade before (January 1, 1994, to December 31, 2003) and for the 13 yr after (January 1, 2004 to December 31, 2016) instituting a random urine drug testing program. A total of 628 residents trained in the program over these 23 yr; they contributed a total of 1,721 resident years for analysis. Fewer faculty and certified nurse anesthetists were studied, so we do not include them in our analysis. RESULTS: The incidence of substance use disorders among trainees in our department during the 10 yr before initiation of urine drug screening was four incidents in 719 resident years or 0.0056 incidents per resident-year. In the 13 yr after the introduction of urine drug screening, there have been zero incidents in 1,002 resident years in our residency program (P = 0.0305). CONCLUSIONS: This single-center, comprehensive program including preplacement and random drug testing was associated with a reduction of the incidence of substance use disorders among our residents in anesthesiology. There were no instances of substance use disorders in our residents over the recent 13 yr. A large, multicenter trial of a more diverse sample of academic, government, and community institutions is needed to determine if such a program can predictably reduce the incidence of substance use disorders in a larger group of anesthesiology residents.

A Comprehensive Review of Transesophageal Echocardiography During Orthotopic Liver Transplantation.

Orthotopic liver transplantation (OLT) is characterized by significant hemodynamic disturbances and anesthetic challenges. Intraoperative transesophageal echocardiography (TEE) can be used to guide management during these procedures. This review examines the role of echocardiography during OLT, presents common TEE findings during each phase of OLT, and discusses the benefits demonstrated with TEE use and the safety of TEE in this patient population. Finally, the authors propose an algorithm for the safe use of TEE during OLT.

Perioperative management of a redo aortic root replacement in a patient with severe factor XI deficiency.

Factor XI deficiency is associated with significant bleeding in the setting of trauma and surgery. We present a patient with FXI deficiency and multiple red blood cell allo-antibodies requiring repeat aortic root replacement and discuss the perioperative management of patients with FXI deficiency undergoing cardiac surgery.

How Cardiac Anesthesiology Can Help "STEM" the Tide of Under-representation of Minorities in Science and Medicine.

The field of medicine is built upon science, technology, engineering, and math (STEM), yet the United States is rapidly falling behind when it comes to educating the next generation in these disciplines, especially under-represented populations. The authors reflect on existing educational literature surrounding efforts to promote interest in STEM among students and under-represented populations. The authors advocate for greater efforts toward the development of youth programing. Cardiac anesthesia is uniquely positioned as a subspecialty to advance the goal of promoting interest in STEM in diverse groups of young students. The authors describe their development and implementation of a community outreach program to enhance interest in medicine through a cardiac dissection experience.
