Intraoperative Hypotension-Physiologic Basis and Future Directions
This new technology has the potential to reduce duration or even prevent IOH. In the authors’ opinion, it is an example of how human-machine interaction will contribute to future advances in medicine. Additional studies should evaluate the effects of its use on postoperative outcomes.
Arterial Carbon Dioxide and Acute Brain Injury in Venoarterial Extracorporeal Membrane Oxygenation
In conclusion, in a cohort with granular arterial blood gas (ABG) data and a standardized neuromonitoring protocol, higher pre-cannulation PaCO2 and larger ΔPaCO2 were associated with increased prevalence of ICH.
Cannulas and Cannulation Options for Minimally Invasive Surgery
Traditionally, cardiac surgery has been practiced primarily through a median sternotomy; however, as instrumentation and experience continue to advance at exponential rates, the field of minimally invasive cardiac surgery (MICS) is rapidly expanding. When compared with a conventional sternotomy, alternative access offers patients the potential benefits of decreased infection risk, reduced transfusion requirements, decreased length of admission, quicker return to normal activity, and, perhaps most important for patients, improved cosmesis. We hereby discuss our approach to cannulation for MICS operations.
Effect Of Aortic Cannulation Depth on Air Emboli Transport during Cardiopulmonary Bypass: A Computational Study.
It was demonstrated that the elongated cannula insertion length resulted in lower embolic loads, particularly at a higher flow rate. The numerical results suggest that CPB management could combine active flow variation with improving cannula performance and provide a foundation for a future experimental and clinical investigation to reduce surgical cerebral air microemboli.
Trends, Advantages and Disadvantages in Combined Extracorporeal Lung and Kidney Support From a Technical Point of View
We conducted a review to provide technical background on existing techniques for extracorporeal lung and kidney support and give insight on important aspects to be addressed in the development of this novel highly integrated artificial lung device.
Effect of Nitric Oxide via Cardiopulmonary Bypass on Ventilator-Free Days in Young Children Undergoing Congenital Heart Disease SurgeryThe NITRIC Randomized Clinical Trial
In children younger than 2 years undergoing cardiopulmonary bypass surgery for congenital heart disease, the use of nitric oxide via cardiopulmonary bypass did not significantly affect the number of ventilator-free days. These findings do not support the use of nitric oxide delivered into the cardiopulmonary bypass oxygenator during heart surgery.
Thrombosis in Extracorporeal Membrane Oxygenation (ECMO) Circuits
Examination of ECMO circuits after removal is a useful quality improvement tool that can elucidate the cause of circuit problems, indicate patients at increased risk of thrombosis, and suggest areas for possible improvements.
Cytokine Adsorption Therapy during Extracorporeal Membrane Oxygenation in Adult Patients with COVID-19
This case series aimed to contribute to the body of evidence substantiating CAT utilization in hyperinflammatory patients, namely, COVID-19 patients requiring ECMO rescue.
Venoarterial Extracorporeal Membrane Oxygenation is A Viable Option as A Bridge to Heart Transplant
Recipients bridged with extracorporeal membrane oxygenation were estimated to survive 16.6 months less than nonmechanical circulatory support recipients. Bridge to heart transplant with extracorporeal membrane oxygenation is a viable option, and these patients should be considered transplant candidates.
Carbon Dioxide Elimination After Sodium Bicarbonate Administration as a Novel Method to Assess Cardiac Output: A Pilot Study
This technique may be a way to intermittently assess cardiac output or improve accuracy when used in conjunction with other continuous output monitors.
ECMO Implantation Training: Needle Penetration in 3D Printable Materials and Porcine Aorta
Shore A 10 and 20 polymers have similar needle penetration properties compared to the porcine tissue. Significantly more force is needed to pierce through the material fully. The most similar tested material to porcine aorta for needle penetration and piercing in ECMO-implantation is the silicon Shore A 10 polymer. This silicon could be a 3D-printable material in surgical training for ECMO-implantation.
Ultrafiltration and Cardiopulmonary Bypass Associated Acute Kidney Injury: A Systematic Review and Meta-Analysis
UF in cardiac surgery is not associated with increased AKI incidence and may be safely used even in baseline chronic injury patients.
