ReviewShould surgeons scrub with chlorhexidine or iodine prior to surgery?
A best evidence topic was written according to a structured protocol. The question addressed was whether chlorhexidine gluconate is equivalent or superior to the use of povidone-iodine during surgical hand scrub. A total of 593 papers were found using the reported searches of which eight represented the best evidence to answer the clinical question. ⋯ Four studies went further to analyse cumulative and residual activity by testing for bacterial reduction after using a scrub solution for a number of days, an area in which chlorhexidine showed consistent advantages over povidone-iodine. These findings are given more credibility by the clinical finding of a recent meta-analysis of over 5000 patients in which chlorhexidine as an antiseptic skin preparation was associated with significantly reduced surgical site infection (SSI) in clean-contaminated surgery. Despite this, there is no evidence suggesting the use of chlorhexidine during hand scrub reduces SSI, which perhaps explains why guidelines from the World Health Organization, the Centers for Disease Control and Prevention and the Association for Perioperative Practice do not recommend one specific antimicrobial over another for hand scrub.

ReviewIn adult patients undergoing redo surgery for left atrioventricular valve regurgitation after atrioventricular septal defect correction, is replacement superior to repair?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'In adult patients undergoing redo surgery for left atrioventricular valve regurgitation after atrioventricular septal defect correction, is replacement superior to repair?' Altogether more than 109 papers were found using the reported search, of which eight represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes, and results of these papers are tabulated. ⋯ We feel that for older patients or for those in whom long-term anticoagulation is a concern, biological prosthesis can be an option, also due to the growing and expanding experience of percutaneous/transapical valve-in-valve replacement in mitral position. Since in these patients the number of previous sternotomies is usually one or more and re-entry injuries can be a major source of perioperative mortality and morbidity, we believe that mini-thoracotomy approach can avoid potential damage; furthermore, arterial cannulation can be either central or peripheral according to the degree of visceral adhesions or surgeon's choice. Venous drainage should be provided by a percutaneous vacuum-assisted femoral double stage venous drainage, which is useful especially when concomitant tricuspid valve surgery is planned.

Preoperative computed tomography is associated with lower risk of perioperative stroke in reoperative cardiac surgery.
Preoperative computed tomography (CT) use appears to be increasing among patients undergoing cardiac reoperations. We hypothesized that preoperative CT imaging reduces adverse outcomes and operative mortality for these patients. From July 2002 to February 2009, 373 patients underwent cardiac reoperations. ⋯ Importantly, perioperative stroke occurred only within the NCT group (5.6% vs. 0.0%, P=0.003), and emergent operative status [odds ratio (OR): 6.45, confidence interval (CI): 1.15-36.10, P=0.03] as an independent multivariate predictor of perioperative stroke. Thus, preoperative CT imaging is associated with lower rates of perioperative stroke in patients undergoing cardiac reoperations by optimizing cannulation and aortic clamping strategies. Routine use of preoperative CT should be considered for patients undergoing cardiac operations following prior sternotomy.

Extracorporeal membrane oxygenator rescue and airborne transportation of patients with influenza A (H1N1) acute respiratory distress syndrome in a Mediterranean underserved area.
Adult respiratory distress syndrome (ARDS) secondary to H1N1 viral infection has been a worldwide medical and organizational challenge. We report our experience with extracorporeal membrane oxygenator (ECMO) rescue and transportation of patients with H1N1 ARDS within an insular and rural Mediterranean area of seven million inhabitants. A 24/7 on-call ECMO team was organized including one anesthesiologist, one cardiac surgeon, and one perfusionist. ⋯ No complications secondary to the transportation means or to the ECMO were reported. Delivery of advanced medical technology can be achieved even in remote and underserved areas presenting geographical barriers. A multidisciplinary mobile ECMO team coordinated with adequate means of transportation could be routinely employed to rescue patients affected with other forms of severe acute hemodynamic and/or respiratory impairment.

Case ReportsPulseCath(R) as a right ventricular assist device.
The PulseCath(®) is a pulsatile pump that offers a circulatory support up to 3 l/min. The PulseCath(®) is indicated for patients who require a higher degree of support than that offered by the intra-aortic balloon pump. We describe the first two cases of the use of the PulseCath(®) as a temporary support for the right ventricle after insertion through the pulmonary artery trunk. ⋯ In the first patient an irreversible metabolic unbalance, already present prior to PulseCath(®) insertion, led to multi-organ failure and eventually to death. In the second case the early utilization of PulseCath(®) led to a complete recovery of the right ventricle and the patient was discharged in good clinical condition. Besides the technical feasibility, this report would suggest that a correct timing is the key to success for the PulseCath(®) as a right ventricular assist device.
