Heparin Therapy during Extracorporeal Circulation: Deriving anOptimal Activated Clotting Time during Cardiopulmonary Bypass for Isolated Coronary Artery Bypass Grafting
The effect of heparin dose, sensitivity, metabolism, patient size, elective/urgent, protamine reversal regime, returned pump blood volume and heparin content, and average ACT during CPB with regard to postoperative blood loss and resternotomy was examined in a consecutive series of patients undergoing isolated coronary artery bypass surgery.
Validation of a Perfusion Registry: Methodological Approach and Initial Findings
Although regional and national registries exist to measure and report performance of cardiac surgical programs, few registries exist dedicated to the practice of cardiopulmonary bypass (CPB). We developed and implemented a cardiovascular perfusion registry (Perfusion Measures and outcomes [PERForm] Registry) within the structure of the Michigan Society of Thoracic and Cardiovascular Surgeons (MSTCVS) to improve our understanding of the practice of CPB.
Endogenous Gas Formation – An In Vitro Study with Relevanceto Gas Microemboli during Cardiopulmonary Bypass
Gas embolism is an identified problem during cardiopulmonary bypass (CPB). Our aim was to analyze the potential influence from gas solubility based on simple physical laws, here called endogenous gas embolism.
Development of a New Arterial Line Filter Design Using Computational Fluid Dynamics Analysis
This article reviews theoretical principles of micropore filter technology and outlines the development of a new arterial-line filter concept using computational fluid dynamics analysis.
A Novel Technique for Intra-aortic Balloon Positioning in the Intensive Care Unit
In this technique, we rely on the left radial arterial trace obliteration as the IABP catheter is pushed in along a guidewire as a marker for tip positioning.
Our Experience with Two Cardioplegic Solutions: Dextrose versus Non-Dextrose in Adult Cardiac Surgery
Intraoperative hyperglycemia has been observed to be associated with increased morbidity and mortality after cardiac surgery. Dextrose cardioplegia is used for its cardioprotective effects but may lead to intraoperative hyperglycemia and more postoperative complications.
Ventricular Assist Device Malfunction: Sometimes It Is a Zebra
Preventing, recognizing, and troubleshooting problems with the many intricate systems used by perfusionists are key skills within the profession.
The Effect of Acute Sleep Deprivation and Fatigue in Cardiovascular Perfusion Students: A Mixed Methods Study
Sleep deprivation as a result of long working hours has been associated with an increased risk of adverse events in healthcare professions but not in cardiovascular perfusion. The purpose of this study is to investigate the impact of sleep deprivation on cardiovascular perfusion students.
Theoretical Treatise: Arterial Pressure during Aortic Surgery
This theoretical treatise predicts that blood pressure management should be temperature- and hematocrit-dependent. The target optimal blood pressure will vary during the course of surgery as a result of heating, cooling, and hemodilution.
Cardiac ECMO Series Report (EP Video)
Monica Olsen provides a summary report on cardiac ECMO (42:59 minutes).
Increasing Surgical Experience with Off-Pump Coronary Surgery Does Not Mitigate the Morbidity of Emergency Conversion to Cardiopulmonary Bypass
The incidence of emergency conversion during OPCAB has decreased with increasing surgical experience; however, the morbidity in these patients remains essentially unchanged. The outcomes in these patients remain worse than those in nonconverted patients. Safer bailout strategies during OPCAB are still warranted.
Totally Thoracoscopic Surgical Treatment for Atrial Septal Defect: A Mid-Term Follow-up Results in 45 Consecutive Patients
Totally thoracoscopic operation provides minimally invasive alternative for patients with atrial septal defect. In this study, we report the mid-term follow-up results of 45 patients with atrial septal defect who underwent totally thoracoscopic operation and discuss the feasibility and safety of this new technique.
