Anticoagulation during extracorporeal membrane oxygenation.

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To determine the efficacy and safety of anticoagulation for maintaining extracorporeal membrane oxygenation in people of all ages with cardiac or respiratory failure, or both.

Mechanical Circulatory Support for Acute Myocardial Infarction Cardiogenic Shock: Review and Recent Updates.

Cardiogenic shock (CS) in acute myocardial infarction (AMI) is a life-threatening syndrome characterized by systemic hypoperfusion that can quickly progress to multiorgan failure and death. Various devices and configurations of mechanical circulatory support (MCS) exist to support patients, each with unique pathophysiological characteristics. The Intra-aortic balloon pump can improve coronary perfusion, decrease afterload, and indirectly augment cardiac output.

Non-adrenergic vasopressors for vasodilatory shock or perioperative vasoplegia: a meta-analysis of randomized controlled trials.

Background: Excessive exposure to adrenergic vasopressors may be harmful. Non-adrenergic vasopressors may spare adrenergic agents and potentially improve outcomes. We aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of non-adrenergic vasopressors in adult patients receiving vasopressor therapy for vasodilatory shock or perioperative vasoplegia.

Oral blood pressure augmenting agents for intravenous vasopressor weaning.

Intravenous (IV) vasopressors are essential in the management of hypotension and shock. Initiation of oral vasoactive agents to facilitate weaning of IV vasopressors to liberate patients from the intensive care unit is common despite conflicting evidence regarding the benefits of this practice. While midodrine appears to be the most frequently studied oral vasoactive agent for this purpose, its adverse effect profile may preclude its use in certain populations.

Early high-dose vasopressors in refractory septic shock: A cohort study.

Purpose: Septic shock refractory to high-dose vasopressors confers unacceptably high mortality, however, the impact of timing of peak vasopressor dose exposure on outcomes is unknown.

Methods: This retrospective cohort study included adults who required a vasopressor dose ≥0.5 μg/kg/min norepinephrine-equivalents in the first 24 h of septic shock.

Analysis of The 2024 ESC/EACTS Guidelines For The Management Of Atrial Fibrillation.

The 2024 European Society of Cardiology guidelines for atrial fibrillation (AF) emphasize a patient-centered approach to management, structured around the AF-CARE pathway: Comorbidity and risk factor management (C), Avoiding stroke and thromboembolism (A), Reducing symptoms through rate and rhythm control (R), and Evaluation and dynamic reassessment (E). This framework ensures that comorbidities such as hypertension, heart failure, diabetes, and obesity are effectively managed to prevent disease progression and improve outcomes. A key principle of the guidelines is shared decision making involving patients, families, caregivers, and healthcare teams to ensure individualized care that reflects patient preferences.

Challenges in renally eliminated medication use: Evaluating cystatin C and serum creatinine eGFR discordance.

Background: Accurately estimating glomerular filtration rate (GFR) is crucial for dosing medications in hospitalized patients. Due to limitations of serum creatinine for GFR estimation, serum cystatin C (CysC) has been explored as an alternative functional kidney biomarker. This study assessed discordance between eGFR and eGFR in a large sample of hospitalized patients and examined the frequency of renally eliminated medications affected by eGFR discordance.

The renin-angiotensin-aldosterone-system in sepsis and its clinical modulation with exogenous angiotensin II.

Dysregulation of the renin-angiotensin-aldosterone-system (RAAS) in sepsis is a complex and early phenomenon with a likely significant contribution to organ failure and patient outcomes. A better understanding of the pathophysiology and intricacies of the RAAS in septic shock has led to the use of exogenous angiotensin II as a new therapeutic agent. In this review, we report a multinational and multi-disciplinary expert panel discussion on the role and implications of RAAS modulation in sepsis and the use of exogenous angiotensin II.

Remimazolam in Cardiac Anesthesia: Analysis of Recent Data.

Interest in remimazolam has surged in recent years, thanks to its advantageous pharmacologic profile. This ultra-short-acting benzodiazepine is noted for its rapid onset and termination of action, organ-independent elimination, availability of a reversal agent, and excellent hemodynamic stability. Although the use of remimazolam has been explored in various anesthesia settings and procedures, data on its application in cardiovascular anesthesia and catheterization laboratory procedures remain limited.

Bivalirudin in Extracorporeal Membrane Oxygenation.

Extracorporeal membrane oxygenation (ECMO) is a mechanical support treatment modality used in patients with refractory cardiac and/or pulmonary failure. Bleeding and thrombotic complications associated with ECMO are inherent concerns that require careful management. Anticoagulation optimization may help mitigate these risks by providing more adequate therapeutic anticoagulation and lessen the bleed risk.

Short-Term Neurologic Complications in Patients Undergoing Extracorporeal Membrane Oxygenation Support: A Review on Pathophysiology, Incidence, Risk Factors, and Outcomes.

Regardless of the type, extracorporeal membrane oxygenation (ECMO) requires the use of large intravascular cannulas and results in multiple abnormalities including non-physiologic blood flow, hemodynamic perturbation, rapid changes in blood oxygen and carbon dioxide levels, coagulation abnormalities, and a significant systemic inflammatory response. Among other sequelae, neurologic complications are an important source of mortality and long-term morbidity. The frequency of neurologic complications varies and is likely underreported due to the high mortality rate.

Inhaled volatile anesthetics in the intensive care unit.

The discovery and utilization of volatile anesthetics has significantly transformed surgical practices since their inception in the mid-19th century. Recently, a paradigm shift is observed as volatile anesthetics extend beyond traditional confines of the operating theatres, finding diverse applications in intensive care settings. In the dynamic landscape of intensive care, volatile anesthetics emerge as a promising avenue for addressing complex sedation requirements, managing refractory lung pathologies including acute respiratory distress syndrome and status asthmaticus, conditions of high sedative requirements including burns, high opioid or alcohol use and neurological conditions such as status epilepticus.

Palliative care in the cardiovascular intensive care unit: A systematic review of current literature.

Background: There has been an evolution in the disease severity and complexity of patients presenting to the cardiac intensive care unit (CICU). There are limited data evaluating the role of palliative care in contemporary CICU practice.

Methods: PubMed Central, CINAHL, EMBASE, Medline, Cochrane Library, Scopus, and Web of Science databases were evaluated for studies on palliative care in adults (≥18 years) admitted with acute cardiovascular conditions - acute myocardial infarction, cardiogenic shock, cardiac arrest, advanced heart failure, post-cardiac surgery, spontaneous coronary artery dissection, Takotsubo cardiomyopathy, and pulmonary embolism - admitted to the CICU, coronary care unit or cardiovascular intensive care unit from 1/1/2000 to 8/8/2022.

Cumulative epinephrine dose during cardiac arrest and neurologic outcome after extracorporeal cardiopulmonary resuscitation.

Background: Epinephrine is recommended without an apparent ceiling dosage during cardiac arrest. However, excessive alpha- and beta-adrenergic stimulation may contribute to unnecessarily high aortic afterload, promote post-arrest myocardial dysfunction, and result in cerebral microvascular insufficiency in patients receiving extracorporeal cardiopulmonary resuscitation (ECPR).

Methods: This was a retrospective cohort study of adults (≥ 18 years) who received ECPR at large academic ECMO center from 2018 to 2022.

Unresponsiveness of Activated Partial Thromboplastin Time to Bivalirudin in Adults Receiving Extracorporeal Membrane Oxygenation.

Activated partial thromboplastin time (aPTT) is the standard for monitoring bivalirudin but demonstrates a nonlinear response at higher drug concentrations. The objective of this study was to assess the relationship between bivalirudin dose and aPTT in patients receiving extracorporeal membrane oxygenation (ECMO) to determine a threshold where aPTT unresponsiveness occurs. Two hundred fourteen adults receiving bivalirudin during ECMO between 2018 and 2022 were included.
