Hemodilution contributes significantly to transfusion requirements in patients undergoing CABG under CPB. We hypothesised that restriction of parenteral fluids in comparison to a liberal fluid administration policy leads to less use of packed red cells in CABG operations supported by cell salvage. After consent and approval, 130 patients operated under ...

BACKGROUNDS/AIMS: We recently demonstrated that pulsatile cardiopulmonary bypass (CPB) versus standard linear CPB is associated with better perioperative renal function. Since older subjects have a higher risk of acute renal failure, we have extended our study to evaluate the specific impact of pulsatile CPB on the perioperative renal function in ...

Though propofol requirement is expected to decrease during cardiopulmonary bypass (CPB), a few studies have failed to demonstrate this. The factors affecting pharmacokinetics of propofol and, therefore, the requirement, are different during hypothermic and normothermic CPB. We evaluated and compared the requirement of propofol during hypothermic and normothermic CPB. Fifty ...

We sought to examine the short- and long-term outcomes of blood transfusion in patients presenting with ST-segment elevation myocardial infarction (STEMI). The short- and long-term consequences of blood transfusion in anemic patients with recent STEMI remain controversial. We evaluated 30-day, 6-month, and 1-year all-cause mortality among 4,131 STEMI patients enrolled ...

Di-(2-ethylhexyl)phthalate (DEHP), an excellent plasticizer for poly(vinyl chloride) (PVC), is a known endocrine-disrupting chemical. This study was designed to investigate whether a new non-DEHP bilayer tube reduced the release of DEHP, suppressed inflammatory cytokines, and altered coagulation-fibrinolysis systems. Sixteen patients undergoing coronary artery bypass grafting (CABG) were randomly assigned to ...
