ReviewDoes use of intraoperative cell-salvage delay recovery in patients undergoing elective abdominal aortic surgery?
A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was whether the use of intraoperative cell-salvage (ICS) leads to negative outcomes in patients undergoing elective abdominal aortic surgery? Altogether 305 papers were found using the reported search, of which 10 were judged to represent 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 were tabulated. ⋯ Indeed two trials actually show a significantly shorter hospital stay after ICS use, one a shorter ITU stay and another suggests lower rates of chest sepsis. Based on these papers, we concluded that the use of ICS does not cause increased morbidity or mortality when compared to standard practise of transfusion of allogenic blood, and may actually improve some clinical outcomes. As abdominal aortic surgery inevitably causes significant intraoperative blood loss, in the range of 661-3755 ml as described in the papers detailed in this review, ICS is a useful and safe strategy to minimise use of allogenic blood.

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.

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.

Should we operate on microscopic N2 non-small cell lung cancer?
Traditionally non-small cell lung cancer (NSCLC) stage N2 is considered as a contraindication for curative resection. We investigated the outcome of patients with microscopic N2 disease, who underwent potentially curative resections. The independent effects of lobectomy vs. pneumonectomy, histology subtype, body mass index (BMI), sex, and PET-scanning were investigated. ⋯ A low N2 survival risk score was associated with increased survival, P=0.001. Resecting microscopic N2 disease in NSCLC may be appropriate in some patients. An N2 survival scoring system may help select patients for surgery, and help evaluate adjuvant and neoadjuvant publications with regard to microscopic N2 disease.

Case ReportsA ruptured mature teratoma in which follow-up computed tomography observation at short intervals was useful for a definitive diagnosis.
Rupture of mature mediastinal teratomas occasionally occurs, necessitating prompt surgical treatment. However, the clinical presentation of a ruptured teratoma can resemble that of pneumonia and/or pleuritis. We report a case of mediastinal teratoma rupture, in which follow-up computed tomography (CT) a short-interval after the first CT was useful for definitive diagnosis. ⋯ Eighteen hours later, a repeat CT-revealed an increase in the soft tissue area of the chest wall adjacent to the tumor, which led to the definitive diagnosis of ruptured teratoma, and immediate resection was performed. The histological diagnosis was a mature teratoma, and rupture was confirmed by the high lipase level in the pleural fluid. The patient's postoperative course was uneventful.
