| 1 | Perfusionist strategies for blood conservation in pediatric cardiac surgery显示文摘There is increasing concern about the safety of homologous blood transfusion during cardiac surgery,and a restrictive transfusion practice is associated with improved outcome.Transfusion-free pediatric cardiac surgery is unrealistic for the vast majority of procedures in neonates or small infants;however,considerable progress has been made by using techniques that decrease the need for homologous blood products or even allow bloodless surgery in older infants and children.These techniques involve a decrease in prime volume by downsizing the bypass circuit with the help of vacuumassisted venous drainage,microplegia,autologous blood predonation with or without infusion of recombinant(erythropoietin),cell salvaging,ultrafiltration and retrograde autologous priming.The three major techniques which are simple,safe,efficient,and cost-effective are:a prime volume as small as possible,cardioplegia with negligible hydric balance and circuit residual blood salvaged without any alteration.Furthermore,these three techniques can be used for all the patients,including emergencies and small babies.In every pediatric surgical unit,a strategy to decrease or avoid blood bank transfusion must be implemented.A strategy to minimize transfusion requirement requires a combined effort involving the entire surgical team with pre-,peri-,and postoperative planning and management. | Yves Durandy | 2010 | World Journal of Cardiology2010，2，2： | 5 |
| 2 | Is there a rationale for short cardioplegia re-dosing intervals?显示文摘While cardioplegia has been used on millions of patients during the last decades, the debate over the best technique is still going on. Cardioplegia is not only meant to provide a non-contracting heart and a field without blood, thus avoiding the risk of gas emboli, but also used for myocardial protection. Its electromechanical effect is easily confirmed through direct vision of the heart and continuous electrocardiogram monitoring, but there is no consensus on the best way to assess the quality of myocardial protection. The optimal approach is thus far from clear and the considerable amount of literature on the subject fails to provide a definite answer. Cardioplegia composition(crystalloid vs blood, with or without various substrate enhancement), temperature and site(s) of injection have been extensively researched. While less frequently studied, re-dosing interval is also an important factor. A common and intuitive idea is that shorter redosing intervals lead to improved myocardial protection. A vast majority of surgeons use re-dosing intervals of 20-30 min, or even less, during coronary artery bypass graft and multidose cardioplegia has been the 'gold standard' for decades. However, one-shot cardioplegia is becoming more commonly used and is likely to be a valuable alternative. Some surgeons prefer the comfort of single-shot cardioplegia while others feel more confident with shorter re-dosing intervals. There is no guarantee that a single strategy can be safely applied to all patients, irrespective of their age, comorbidities or cardiopathy. The goal of this review is to discuss the rationale for short re-dosing intervals. | Yves D Durandy | 2015 | World Journal of Cardiology2015，7，10： | 1 |

| 5 | Mediastinitis in pediatric cardiac surgery:Prevention,diagnosis and treatment显示文摘In spite of advances in the management of mediastinitis following sternotomy,mediastinitis is still associated with significant morbidity.The prognosis is much better in pediatric surgery compared to adult surgery,but the prolonged hospital stays with intravenous therapy and frequent required dressing changes that occur with several therapeutic approaches are poorly tolerated.Prevention includes nasal decontamination,skin preparation,antibioprophylaxis and air filtration in the operating theater.The expertise of the surgical team is an additional factor that is difficult to assess precisely.Diagnosis is often very simple,being made on the basis of a septic state with wound modification,while retrosternal puncture and CT scan are rarely useful.Treatment of mediastinitis following sternotomy is always a combination of surgical debridement and antibiotic therapy.Continued use of numerous surgical techniques demonstrates that there is no consensus and the best treatment has yet to be determined.However,we suggest that a primary sternal closure is the best surgical option for pediatric patients.We propose a simple technique with high-vacuum Redon's catheter drainage that allows early mobilization and short term antibiotherapy,which thus decreases physiological and psychological trauma for patients and families.We have demonstrated the ef-ficiency of this technique,which is also cost-effective by decreasing intensive care and hospital stay durations,in a large group of patients. | Yves Durandy | 2010 | World Journal of Cardiology2010，2，11： | 0 |
