Filter by:The purpose of this study is to evaluate the safety and efficacy of a system combining continuous glucose measurement with a computer-based algorithm for insulin delivery in patients undergoing elective cardiac surgery.
The RECESS study will compare the effects of transfusing red blood cell units stored <= 10 days vs. red blood cell units stored >= 21 days, in patients who are undergoing complex cardiac surgery and are likely to need a red blood cell transfusion. The primary hypothesis is that there is a clinically important difference between the effects of shorter-storage red cell units and longer-storage red cell units on clinical outcomes and mortality risk.
Oxidative stress is an unavoidable event during cardiac surgery. Isoprostanes have been demonstrated to be a reliable biomarker for the evaluation of oxidative stress in vivo.The aims of this study are(1)to develop an accurate liquid chromatography-tandem mass spectrometry methods for the detection of urinary isoprostane isomers in samples collected from healthy volunteers(for method quality control) and patients receiving a cardiac surgery (2)to investigate the change of isoprostanes after cardiopulmonary bypass(CPB) (3)to investigate the effect of different anesthetics on isoprostanes.
This large randomized double-blind clinical trial (esmolol vs placebo) will enroll patients undergoing cardiac surgery to study the additive cardiac protection of this therapeutic strategy.
PURPOSE: Autotransfusion devices may be employed in cardiac surgery to decrease allogenic blood requirements. Limitations of previous trials include the use of cell saver systems in selected high risk patients only or the lack of blood transfusion-sparing strategies. The aim of this prospective randomized study is to evaluate the efficacy of cell salvage CardioPAT routinely used in cardiac surgery. METHODS: The investigators will randomize 350 patients in two groups: group 1 receives a CardioPAT cell saver device (175 patients), group 2 doesn't receive any cell saver device. The incidence of allogenic blood transfusion and clinical outcome in both groups are evaluated.
The administration of rhEPO on the one day before cardiac surgery will be effective to decrease the bleeding due to the surgery.
The purpose of the present research study is to investigate the pharmacokinetics, as well as safety, tolerability and pharmacodynamics of different ascending dosing regimens of AP214 in patients undergoing cardiac surgery. AP214, the investigational drug, is being developed to potentially prevent post-surgical kidney injury after thoracic aortic aneurysm repair.
The objective of this study is to verify, through a randomized, single-blind, multicentre, parallel and comparative study, the effectiveness of heparin sodium of porcine origin in patients undergoing heart surgery at that require the aid of cardiopulmonary bypass, through the control of hemostasis during and after surgery, based on the strengths of markers of coagulation TCA, TTPA, Anti-Xa, heparin bioavailable and loss of excessive blood (bleeding) at the end of the surgery.
