Evaluation of Recirculation During Venovenous Extracorporeal Membrane Oxygenation Using Computational Fluid Dynamics Incorporating Fluid-Structure Interaction
We have developed a finite element computational fluid dynamics model incorporating fluid-structure interaction (FSI) that incorporates atrial deformation during atrial filling and emptying, with fluid flow solved using large eddy simulation. With this model, we have evaluated an extensive number of factors that could influence recirculation during two-site VV ECMO, and characterized their impact on recirculation, including cannula construction, insertion depth and orientation, VV ECMO configuration, circuit blood flow, and changes in volume, venous return, heart rate, and blood viscosity.
Central Versus Peripheral Arterial Cannulation for Veno-Arterial Extracorporeal Membrane Oxygenation in Post-Cardiotomy Patients
Central cannulation for VA-ECMO provides antegrade flow without Harlequin’s syndrome, changes of arterial cannula site, and better 30 day survival. Complication rates regarding need for reexploration and transfusion requirements were similar.
Aortic Flow Below and Visceral Circulation During Aortic Counterpulsation: Evaluation of An In Vitro Model
The presented mock circulation was reliable and gave values with high accuracy both at baseline and during mechanical assistance. This system allows evaluation of the mesenteric flow during IABP, under different clinical/hemodynamic conditions. Nonetheless, its translational potential needs to be further evaluated
Clinical Characteristics and Outcomes of Adults with Peripheral Extracorporeal Membrane Oxygenation in A Developing Country: A Single Center 8-Year Retrospective Study
The mortality rate in our ECMO center was considerably higher than that in the international registry report. Improved team education, rigid patient selection criteria, and a reimbursement protocol should lead to ameliorated outcomes.
Extracorporeal Life Support for Cardiogenic Shock with Either A Percutaneous Ventricular Assist Device or An Intra-Aortic Balloon Pump
Careful considerations are required before selecting an additional support to ECLS.
Outcomes of Cardiac Surgery in Jehovah’s Witness Patients: A Review.
The use of a bloodless protocol for Jehovah’s Witnesses does not appear to significantly impact upon clinical outcomes when compared to non-Witness patients, and it has even been suggested that a bloodless approach could provide advantages to all patients undergoing cardiac surgery. Larger cohorts and research across multiple centres into the long term outcomes of these patients is required.
Perioperative Cardioprotection: General Mechanisms and Pharmacological Approaches
This review presents the fundamental mechanisms of conditioning strategies and provides an overview of the most recent and relevant findings on different concepts achieving cardioprotection in the experimental setting, specifically emphasizing pharmacological approaches in the perioperative context.
International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations
After discussion of the scoping reviews and the evidence update, the task force prioritized several topics for new systematic reviews.
Pediatric Intensive Care Preparedness and ECMO Availability in Children With COVID-19: An International Survey
In conclusion, both the experience in managing patients and the availability of neonatal/pediatric ECMO in the centers the responders are working seemed to increase physicians’ preparedness.
Prompt Prediction of Fibrinogen Concentration During Cardiopulmonary Bypass: A Pilot Study
Our results indicate a strong correlation between fibrinogen activation and serum fibrinogen concentration. The maximum amplitude of activator f can estimate low fibrinogen concentration faster than traditional methods; this method quickly provides important information for anesthesia and hemostatic management in cardiac surgery.
Efficacy and Safety of Corticosteroids Prophylaxis in Cardiac Surgery: A Protocol for Systematic Review and Meta-Analysis
This study will compare the efficacy of prophylactic corticosteroids for adults and children undergoing cardiac surgery with CPB. Due to the nature of the disease and intervention methods, randomized controlled trials may be inadequate, and we will carefully consider inclusion in high-quality, non-randomized controlled trials, but this may result in high heterogeneity and affect the reliability of the results.
Anesthesiology Research Using Surgical Registries: Consider the Source
Anesthesiologists should take a lead role in studying this specialty and should be involved in development and maintenance of surgical specialty databases and quality improvement initiatives. The reliability of the data is at stake.
