چکیده

The coronary Bypass operation at the beating heart ("off-pump surgery") is a new procedure which promises advantages in comparison to the established procedure with uses a heart-lung machine ("on-pump-surgery"). In the presented HTA report cardiac surgery the question is investigated, whether there are advantages of the off-pump-surgery in comparison to the on-pump-surgery regarding medical effectiveness, safety as well as cost effectiveness. At the beginning a systematic literature search was done, the articles were classified according to the hierarchy of evidence. There are partly considerable different groups of patients included in the different studies as well as quite different outcome parameters. The quality of the studies in detail, where at least two groups are compared was generally very good.The studies results show more or less equivalent results in the comparison of the two operation techniques. Concluding neither a clinical superiority nor an inferiority on the basis of the present available studies can therefore be proven (off-pump Coronary Artery Bypass; OPCAB) or the conventional bypass operation with use of the heart-lung machine (Coronary Artery Bypass Graft; CABG can).The diagnostic criteria of a patient who is allocated to the one or other operating technique are important. Due to technical reasons the majority of patients with the necessity of a bypass operation con only be treated by CABG, (on-pump-surgery). These criteria for the allocation of operation techniques should be the important components of optimization considerations.

On-Pump Beating Coronary Artery Bypass in High Risk Coronary Patients

Background: There are some conflicting results with Conventional Coronary Artery Bypass Grafts (CCABG) with arrested heart in coronary high-risk patients. Moreover, performing off-pump CABG in these cases may be associated with serious complications. The objective of this study is to evaluate the efficacy of the on-pump beating CABG (OPBCABG) in coronary high-risk patients in comparison with th...

Use of Carbon dioxide versus air blower in on-pump beating-heart coronary artery bypass surgery

Introduction:  The use of carbon dioxide blower has been recognized as the standard of care in patients undergoing beating coronary artery bypass grafting (CABG) due to higher solubility and lower risk of embolization. On the other hand, the compressed air blower has gone out of use since air can be easily trapped and is less soluble which can cause coronary embolism. The prese...

Base deficit in the immediate postoperative period of open-heart surgery and patient outcome

 Abstarct Background: Base deficit is a non-respiratory indicator of acid base status that evaluates the severity of shock at the cellular level. Base deficit results from cellular metabolism of pyruvate under anaerobic conditions. In this situation, base deficit is a sensitive marker of the magnitude of anaerobic metabolism and tissue oxygen deficit [1]. Several studies have shown a strong pos...
