Membrane Lung and Blood Pump Use During Prolonged Extracorporeal Membrane Oxygenation
This manuscript describes the use of membrane lungs and blood pumps used during ECLS support from 2002 to 2017 in over 65,000 patients reported to the Extracorporeal Life Support Organization Registry. Device longevity and complications associated with membrane lungs and blood pump are described and stratified by age group: neonates, pediatrics, and adults.
Switching to Centrifugal Pumps May Decrease Hemolysis Rates Among Pediatric ECMO Patients
These data suggest decreasing rates of hemolysis with centrifugal pumps compared to roller pumps. Since hemolysis was also associated with increased risk of death, these data support the switch from roller to centrifugal pumps at ECMO centers.
Effects of Implementing Rotational Thromboelastometry in Cardiac Surgery: A Retrospective Cohort Study
The use of thromboelastometry testing was associated with increased possibility to receive coagulation product transfusions. However, it appears that thromboelastometry testing was mostly used to assist in management of major bleeding.
Extension of Cardiopulmonary Bypass Outside the Operating Room as A Short-Term Bridge to Recovery “The Poor Man’s ECMO”
This report describes the use of conventional cardiopulmonary bypass (CPB) circuit beyond the operating room to the critical care unit to provide cardiopulmonary support for patients requiring emergent resuscitation as well as short-term support for rest and recovery of the heart.
Validation of Transcutaneous Carbon Dioxide Monitoring Using an Artificial Lung During Adult Pulsatile Cardiopulmonary Bypass
Our experience in utilizing tcCO2 during CPB has demonstrated accuracy in estimating PaCO2 when compared to the gold standard arterial blood gas analysis, even during CO2 flooding of the surgical field.
Blood Oxygenation Using Fluoropolymer-Based Artificial Lung Membranes
The blood oxygenation performance was assessed using animal sheep blood, and the fabricated fluoropolymer membranes showed competitive performance to that of commercial polyolefin membranes without any detectable hemolysis. The data also confirmed that the bottleneck in the blood oxygenation performance was not the membrane permeance but rather the rate of mass transfer in the blood phase, highlighting the importance of efficient module design.
ECMELLA: Successful Rescue Cardiopulmonary Support in Post-Coronary Artery Bypass Graft Cardiogenic Shock with Cardiac Arrest-Case Report
Although there is limited evidence of the benefit of a combined use of mechanical support (VA-ECMO with other mechanical devices) in the management of cardiogenic shock and cardiac arrest following CABG surgery, there seems to be a lower mortality with this approach, and possibly more favourable neurological outcomes. Further research is needed to elucidate the advantages of Impella vs. intra-aortic balloon pump combined with VA-ECMO in such patients.
Concurrent Use of Renal Replacement Therapy during Extracorporeal Membrane Oxygenation Support: A Systematic Review and Meta-Analysis
RRT on ECMO was associated with higher mortality rates and a longer ICU/hospital stay compared to those without RRT. Future research should focus on minimizing renal dysfunction in ECMO patients and define the optimal timing of RRT initiation.
Perfusion Strategy Using Axillary or Femoral Cannulation for Minimally Invasive Cardiac Surgery: Experience in 270 Patients with Computed Tomography-Based Criteria
We believe our CT-based perfusion strategy using AC or FC minimized brain embolic rates. AC can be a good alternative to prevent brain embolization for minimally invasive cardiac surgery patients with advanced atherosclerotic disease.
Use of the Hypotension Prediction Index During Cardiac Surgery
HPI predicted hypotensive episodes during cardiac surgeries with a high degree of sensitivity and specificity.
Percutaneous Femoral Cannulation and Decannulation Using A Plug-Based Vascular Closure Device in Minimally Invasive Cardiac Surgery
These findings indicate that the technique of percutaneous cannulation presented in this tutorial decreases complications frequently seen with surgical cutdown. The risk of conversion to surgical cutdown iswas low. The risk of stenosis of the femoral artery seems to be reduced if distal perfusion is confirmed by ultrasound at the end of the procedure.
Hemolysis at Low Blood Flow Rates: In-Vitro and In-Silico Evaluation of A Centrifugal Blood Pump
These findings underline the urgent need for a specific pump optimized for low-flow treatment. Due to the inherent problems of available centrifugal pumps in the low-flow range, clinicians should use the current centrifugal pumps with caution, alternatively other pumping principles such as positive displacement pumps may be discussed in the future.
