Abstract
BACKGROUND AND RESEARCH QUESTION In case of events such as a cyber attack or a mass casualty incident, ad hoc measures have to be taken in hospitals. As part of the critical infrastructure, hospitals are required by law to prepare, update and exercise alarm and emergency plans for various special situations. The processes and instruments involved for emergency response are defined in the hospital alert and emergency planning. The present study aims to explain with which resources and for which special situations hospitals are prepared. METHODS A prospective, exploratory, anonymous survey of hospitals in Germany was conducted. Hospitals with both internal medicine and surgery departments were included. Out of 2497 hospitals listed in the German Hospital Directory ( www.deutsches-krankenhaus-verzeichnis.de ), 1049 met the inclusion criteria. After correcting for hospital groups with shared administrations, 850 employees were identified and contacted by e‑mail. Quality and risk management managers were asked about resources, risks, and content of their own hospital alert and emergency planning using a standardized questionnaire. The survey was conducted using the online platform EFS Survey (Tivian XI GmbH, Cologne) via www.unipark.de . Access to the survey was via a nonpersonalized hyperlink. Apart from the size and type of hospital surveyed, no data were collected that would allow identification of an individual person. RESULTS Of the participating hospitals 45% (n = 43) were primary care hospitals, 24% (n = 23) were specialty care hospitals, 10% (n = 9) were nonuniversity maximum care hospitals, and 21% (n = 20) were university maximum care hospitals. In total 95 hospitals participated in the survey, of which 98% (n = 93) reported having a hospital alert and emergency plan. Preparation for individual scenarios varied widely. Of the participating hospitals 45% (n = 43) reported having been the target of cyber attacks with an emphasis on maximum care hospitals (55%, n = 11 of 20). Technical redundancy for computer systems is available in 67% (n = 63) of participating hospitals, while independent means of communication exist in 50% (n = 47) of hospitals. A physician-staffed crisis and disaster management unit existed in 60% (n = 56) of the surveyed hospitals. At least a part time position for planning issues was installed in 12 hospitals. CONCLUSION Most participating hospitals are aware of the need for a hospital alert and emergency plan and have various scenario-specific plans in place. Especially mass casualty events, fire and hospital evacuation scenarios are uniformly covered among participating hospitals; however, gaps appear to exist not only for chemical, biological or radionuclear situations but also especially in the area of extreme weather events and infrastructure failures. Only about two thirds of all participating hospitals have contingency plans for water supply and/or heating failures. An important limitation of the study is the comparatively low response rate of 12.9% (n = 95 of 850). While primary care hospitals were underrepresented in the study, 32% of Germany's larger hospitals (> 800 beds) participated. In the future, there is a particular need to engage enough medical staff in the area of hospital alert and emergency planning and refunding of these measures by hospitals.

Abstract
Abstract
Introduction
After solid organ transplantation every second patient develops transplant vasculopathy (TV), which still remains the major obstacle for long-term graft survival. The main risk factor for developing TV are de novo synthesized donor-specific antibodies binding molecules of the MHC complex (HLA complex in humans, respectively) on the surface of endothelial cells (EC). EC become activated, vascular smooth muscle cells proliferate, and monocytes are recruited, contributing the development of the neointima a hallmark of TV. We have demonstrated that the anti-HLA I antibody (w6/32) significantly increases transmigration of monocytes across an endothelial monolayer in vitro. These interactions were dependent on modulating the anti-inflammatory enzyme heme oxygenase (HO)-1.
Purpose
The aim of the project is to investigate which adhesion molecule might mediate the antibody-induced transmigration of monocytes sensitive to HO-1 modulation and whether this modulation has beneficial effects in an allogenic aortic transplantation model in mice.
Methods
Before w6/32 stimulation, HO-1 was modulated by pretreating Human Coronary Artery Endothelial Cells (HCAEC) either with CoPPIX as a HO-1 activator or with statins to test for a therapeutic approach. Expression of a variety of established adhesion receptors in HCAEC was screened after HO-1 modulation and w6/32 stimulation. Antibody-induced transmigration and adhesion of THP-1 were quantified in the presence of CD62E-blocking antibodies. Thoracic aorta was transplanted into the abdominal aorta between fully MHC mismatched mice and applying the corresponding anti-MHC I antibody (SF1-1.1) induced TV. Mice were treated with CoPPIX, statins or CORM to evaluate the effects of HO-1 modulation or its metabolite CO on TV development. Statistical evaluation was performed with t-test or ANOVA.
Results
HO-1 modulation in HCAEC diminished w6/32-induced THP-1 transmigration. CD62E-expression in HCAECs was enhanced after w6/32 stimulation on mRNA and protein level, but preincubation with CoPPIX or statins reduced these effects. Incubation of HCAEC with a CD62E-blocking antibody after w6/32 stimulation significantly diminished the rate of transmigration normalized to isotype-stimulated HCAEC (isotype 100%, w6/32 + IgG 226% vs. w6/32 + CD62E-block 138%, p<0.05.). Treatment of mice with CoPPIX resulted in a significant reduction of the SF1-1.1-induced number of transmigrated monocytes (SF1-1.1: 10 vs. CoPPIX: 5.4; p<0.05). Application of statins (SF1-1.1: 10 vs. statin 6.6; p<0.05) or CORM (CORM: 6.1 vs. iCORM: 11.3, p<0.05) significantly reduces monocyte number as well. In all treatment groups, the SF1-1.1-induced neointima formation was ameliorated.
Conclusion
w6/32-induced monocyte transmigration is CD62E-dependent. SF1-1.1-induced monocytic infiltrate and intimal hyperplasia in a murine aortic transplantation model is also CD62E dependent and amenable to HO-1 modulation.

Abstract
Die perkutane hepatische Chemosaturation ist eine Behandlungsoption bei nichtresektablen primären oder sekundären Lebertumoren. Dabei wird der Bereich der Lebervenenmündung der Vena cava inferior (VCI) mittels 2 Ballons von der Zirkulation isoliert, sodass die systemische Verteilung des über die Leberarterie applizierten Chemotherapeutikums Melphalan verhindert wird. Nach Passage der Leber und venöser Drainage aus der retrohepatischen VCI durchläuft das chemosaturierte Blut 2 parallel geschaltete extrakorporale Filter. Anschließend wird das gereinigte Blut jugulär rückgeführt. Das Verfahren geht oft mit einer ausgeprägten hämodynamischen Instabilität einher, deren Ursache nicht abschließend geklärt ist. Zusätzlich stellt das Gerinnungsmanagement eine Herausforderung dar. Die Autoren berichten von einem Fall, bei dem sich trotz ausreichender „activated clotting time“ (ACT) ein Thrombus im rückführenden Schenkel der extrakorporalen Zirkulation bildete. Gezielte Problemsuche und -lösung waren parallel zur hämodynamischen Stabilisierung und interdisziplinären Zusammenarbeit notwendig, um die Intervention erfolgreich durchzuführen und der Patientin eine sichere Therapie zukommen zu lassen.

Abstract
INTRODUCTION Microcirculatory alterations are key mechanisms in sepsis pathophysiology leading to tissue hypoxia, edema formation, and organ dysfunction. Hyperspectral imaging (HSI) is an emerging imaging technology that uses tissue-light interactions to evaluate biochemical tissue characteristics including tissue oxygenation, hemoglobin content and water content. Currently, clinical data for HSI technologies in critical ill patients are still limited. METHODS AND ANALYSIS TIVITA® Tissue System was used to measure Tissue oxygenation (StO2), Tissue Hemoglobin Index (THI), Near Infrared Perfusion Index (NPI) and Tissue Water Index (TWI) in 25 healthy volunteers and 25 septic patients. HSI measurement sites were the palm, the fingertip, and a suprapatellar knee area. Septic patients were evaluated on admission to the ICU (E), 6 h afterwards (E+6) and three times a day (t3-t9) within a total observation period of 72 h. Primary outcome was the correlation of HSI results with daily SOFA-scores. RESULTS Serial HSI at the three measurement sites in healthy volunteers showed a low mean variance expressing high retest reliability. HSI at E demonstrated significantly lower StO2 and NPI as well as higher TWI at the palm and fingertip in septic patients compared to healthy volunteers. StO2 and TWI showed corresponding results at the suprapatellar knee area. In septic patients, palm and fingertip THI identified survivors (E-t4) and revealed predictivity for 28-day mortality (E). Fingertip StO2 and THI correlated to SOFA-score on day 2. TWI was consistently increased in relation to the TWI range of healthy controls during the observation time. Palm TWI correlated positively with SOFA scores on day 3. DISCUSSION HSI results in septic patients point to a distinctive microcirculatory pattern indicative of reduced skin oxygenation and perfusion quality combined with increased blood pooling and tissue water content. THI might possess risk-stratification properties and TWI could allow tissue edema evaluation in critically ill patients. CONCLUSION HSI technologies could open new perspectives in microcirculatory monitoring by visualizing oxygenation and perfusion quality combined with tissue water content in critically ill patients - a prerequisite for future tissue perfusion guided therapy concepts in intensive care medicine.

Abstract
Endotoxemia impairs hypoxic pulmonary vasoconstriction which leads to systemic hypoxemia. This derogation is attributable to increased activity of nitric oxide synthase 2 and arginase metabolism. Gene expression analysis has shown increased expression of ornithine decarboxylase in lungs of endotoxemic mice, a downstream enzyme of arginase metabolism. The aim of this study was to investigate whether inhibition of ornithine decarboxylase increases hypoxic pulmonary vasoconstriction in lungs of endotoxemic mice. Mice received lipopolysaccharides or saline intraperitoneal, and hypoxic pulmonary vasoconstriction was measured using an isolated perfused mouse lung model. Additional mice with and without endotoxemia were pretreated with the ornithine decarboxylase-inhibitor difluoromethylornithine before examination of hypoxic pulmonary vasoconstriction. Hypoxic pulmonary vasoconstriction was defined as the difference of pulmonary arterial pressure between normoxic and hypoxic ventilation. In addition, lung tissue was analyzed using real-time quantitative polymerase chain reaction, Western blot and immunohistochemistry. Lipopolysaccharides caused an up-regulation of ornithine decarboxylase mRNA level (2.73 ± 0.19-fold increase, p < 0.05) as well as ornithine decarboxylase protein level (4.05 ± 0.37-fold increase, p < 0.05). Endotoxemia attenuated hypoxic pulmonary vasoconstriction when compared with untreated control mice (26.3 ± 9.7% vs. 67.0 ± 17.5%). Difluoromethylornithine (20, 100, 500 mg kg−1 body weight intraperitoneal) restored hypoxic pulmonary vasoconstriction in lungs of endotoxemic mice in a dose-dependent way (25.8 ± 9.9%, 57.3 ± 17.2%, 62.3 ± 12.4%) and decreased hypoxic pulmonary vasoconstriction in control mice (53.6 ± 13.6%, 40.0 ± 14.9%, 35.9 ± 12.4%). These results show that endotoxemia induces ornithine decarboxylase expression and suggest that ornithine decarboxylase contributes to the endotoxemia-induced impairment of hypoxic pulmonary vasoconstriction. Inhibition of ornithine decarboxylase might be a target in the therapy of diseases with inflammation impaired hypoxic pulmonary vasoconstriction, like the sepsis-associated acute respiratory distress syndrome (ARDS).

Abstract
Multidrug-resistant pathogens often lead to treatment failure of antimicrobial regimens. After a period of imbalance between the occurrence/spread of resistance mechanisms and the development of new substances, some new substances have meanwhile been approved and many more are currently undergoing clinical testing. They are particularly effective against specific resistance mechanisms/pathogens and should be preserved for definitive treatment of an isolated pathogen. In the absence of alternatives reserve antibiotics, such as aztreonam and colistin have experienced a renaissance. They are again used in special infection scenarios and clinically tested in combination with new substances. Despite the introduction and development of new substances the building of resistance will at some time also render these (at least partially) ineffective. Therefore, their implementation must be carried out according to the antibiotic or infectious diseases stewardship.

Abstract
Intravascular fluid administration belongs to the cornerstones of perioperative treatment with a substantial impact on surgical outcome especially with respect to major abdominal surgery. By avoidance of hypovolemia and hypervolemia, adequate perioperative fluid management significantly contributes to the reduction of insufficient tissue perfusion as a determinant of postoperative morbidity and mortality. The effective use of intravascular fluids requires detailed knowledge of the substances as well as measures to guide fluid therapy. Fluid management already starts preoperatively and should be continued in the postoperative setting (recovery room, peripheral ward) considering a patient-adjusted and surgery-adjusted hemodynamic monitoring. Communication between all team members participating in perioperative care is essential to optimize fluid management.

Abstract
BACKGROUND Clinically, coronavirus disease 2019 (COVID-19) is associated with a wide range of symptoms, which can range from mild complaints of an upper respiratory infection to life-threatening hypoxic respiratory insufficiency and multiorgan failure. OBJECTIVE The initially identified pulmonary damage patterns, such as diffuse alveolar damage in acute lung failure, are accompanied by new findings that draw a more complex scenario. These include microvascular involvement and a wide range of associated pathologies of multiple organ systems. A back-scaling of microstructural vascular changes is possible via targeted correlation of pathological autopsy results with radiological imaging. MATERIAL AND METHODS Radiological and pathological correlation as well as microradiological imaging to investigate microvascular involvement in fatal COVID-19. RESULTS The cases of two COVID-19 patients are presented. Patient 1 showed a relative hypoperfusion in lung regions that did not have typical COVID-19 infiltrates; the targeted post-mortem correlation also showed subtle signs of microvascular damage even in these lung sections. Patient 2 showed both radiologically and pathologically advanced typical COVID-19 destruction of lung structures and the case illustrates the damage patterns of the blood-air barrier. The perfusion deficit of the intestinal wall shown in computed tomography of patient 2 could not ultimately clearly be microscopically attributed to intestinal microvascular damage. CONCLUSION In addition to microvascular thrombosis, our results indicate a functional pulmonary vasodysregulation as part of the pathophysiology during the vascular phase of COVID-19. The clinical relevance of autopsies and the integration of radiological imaging findings into histopathological injury patterns must be emphasized for a better understanding of COVID-19.

Abstract
Sphingosine‑1‑phosphate (S1P) plays a key role in cell survival, growth, migration, and in angiogenesis. In glioma, it triggers the activity of the S1P‑receptor 1 and of the sphingosine kinase 1; thus influencing the survival rate of patients. The aim of the present study was to investigate the anti‑proliferative effect of the S1P analogue FTY720 (fingolimod) in glioblastoma (GBM) cells. A172, G28, and U87 cells were incubated with micromolar concentrations of FTY720 or temozolomide (TMZ) for 24 to 72 h. Proliferation and half maximal inhibitory concentration (IC50) were determined by using the xCELLigence system. FACS analysis was performed to check the cell cycle distribution of the cells after a 72‑h incubation with FTY720. This was then compared to TMZ‑incubated and to untreated cells. Gene expression was detected by RT‑qPCR in A172, G28, U87 and three primary GBM‑derived cell lines. FTY720 was able to reduce the number of viable cells. The IC50 value was 4.6 µM in A172 cells, 17.3 µM in G28 cells, and 25.2 µM in U87 cells. FTY720 caused a significant arrest of the cell cycle in all cells and stabilized or over‑expressed the level of AKT1, MAPK1, PKCE, RAC1, and ROCK1 transcripts. The TP53 transcript level remained stable or was downregulated after treatment with FTY720. FTY720 may be a promising target drug for the treatment of GBM, as it has a strong anti‑proliferative effect on GBM cells.

Abstract
BACKGROUND The relevance of vancomycin resistance in enterococcal blood stream infections (BSI) is still controversial. Aim of this study was to outline the effect of vancomycin resistance of Enterococcus faecium on the outcome of patients with BSI after orthotopic liver transplantation (OLT). METHODS The outcome of OLT recipients developing BSI with vancomycin-resistant (VRE) versus vancomycin-susceptible Enterococcus faecium (VSE) was compared based on data extraction from medical records. Multivariate regression analyses identified risk factors for mortality and unfavourable outcomes (defined as death or prolonged intensive care stay) after 30 and 90 days. RESULTS Mortality was similar between VRE- (n = 39) and VSE- (n = 138) group after 30 (p = 0.44) or 90 days (p = 0.39). Comparable results occurred regarding unfavourable outcomes. Mean SOFANon-GCS score during the 7-day-period before BSI onset was the independent predictor for mortality at both timepoints (HR 1.32; CI 1.14-1.53; and HR 1.18; CI 1.08-1.28). Timely appropriate antibiotic therapy, recent ICU stay and vancomycin resistance did not affect outcome after adjusting for confounders. CONCLUSION Vancomycin resistance did not influence outcome among patients with Enterococcus faecium bacteraemia after OLT. Only underlying severity of disease predicted poor outcome among this homogenous patient population. TRIAL REGISTRATION This study was registered at the German clinical trials register (DRKS-ID: DRKS00013285).

Abstract
Sepsis-induced changes in pharmacokinetic parameters are a well-known problem in intensive care medicine. Dosing of antibiotics in this setting is therefore challenging. Alterations to the substance-specific kinetics of anti-infective substances have an effect on the distribution and excretion processes in the body. Increased clearance and an increased distribution volume (Vd) and particularly compromized organ function with reduced antibiotic elimination are often encountered in patients with sepsis. Renal replacement treatment, which is frequently used in intensive care medicine, represents a substantial intervention in this system. Current international guidelines recommend individualized dosing strategies and adaptation of doses according to measured serum levels and pharmacokinetic/pharmacodynamic (PK/PD) parameters as concepts to optimize anti-infective therapy in the critically ill. Likewise, the recommendation to adjust the administration form of beta-lactam antibiotics to prolonged or continuous infusion can be found increasingly more often in the literature. This article reviews the background of the individual dosing in intensive care patients and their applicability to the clinical routine.

Abstract
The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) have been available since the beginning of 2016. SEPSIS-3 completely replaces the old SIRS criteria in the definition of sepsis and defines sepsis from now on as "life-threatening organ dysfunction caused by a dysregulated host response to infection". However, it seems questionable whether in clinical practice the new definition is really superior to the old one. The most important question is the following: Is it helpful to have a definition that first recognizes a patient once organ dysfunction has occurred and the patient already needs intensive care?

Abstract
Background Ischemia of intestinal organs is a main cause of complications in surgical intensive care patients. Changes in the tonus of arteries contributing to vascular resistance play an important role in the determination of blood flow and thus oxygen supply of various abdominal organs. It is generally acknowledged that hypoxia itself is able to alter arterial tonus and thus blood flow. Methods The present study compared the effects of various degrees of hypoxia on second-order mesenteric arteries from male C57BL/6J mice. After vessel isolation and preparation, we assessed vessel diameter using an arteriograph perfusion chamber. Investigating mechanisms promoting hypoxia-induced vasodilatation, we performed experiments in Ca2+-containing and Ca2+-free solutions, and furthermore, Ca2+-influx was inhibited by NiCl2, eNOS−/−-, and TASK1−/−-mice were investigated too. Results Mild hypoxia 14.4% O2 induced, in 50% of mesenteric artery segments from wild-type (wt) mice, a vasodilatation; severe hypoxia recruited further segments responding with vasodilatation reaching 80% under anoxia. However, the extension of dilatation of luminal arterial diameter reduced from 1.96% ± 0.55 at 14.4% O2 to 0.68% ± 0.13 under anoxia. Arteries exposed to hypoxia in Ca2+-free solution responded to lower oxygen levels with increasing degree of vasodilatation (0.85% ± 0.19 at 14.4% O2 vs. 1.53% ± 0.42 at 2.7% O2). Inhibition of voltage-gated Ca2+-influx using NiCl2 completely diminished hypoxia-induced vasodilatation. Instead, all arterial segments investigated constricted. Furthermore, we did not observe altered hypoxia-induced vasomotion in eNOS−/−- or TASK1−/− mice compared to wt animals. Conclusions The present study demonstrated that hypoxic vasodilatation in mice mesenteric arteries is mediated by a NO-independent mechanism. In this experimental setting, we found evidence for Ca2+-mediated activation of ion channels causing hypoxic vasodilatation.

Abstract
The mortality of patients with sepsis and septic shock is still unacceptably high. An effective antibiotic treatment within 1 h of recognition of sepsis is an important target of sepsis treatment. Delays lead to an increase in mortality; therefore, structured treatment concepts form a rational foundation, taking relevant diagnostic and treatment steps into consideration. In addition to the assumed focus and individual risks of each patient, local resistance patterns and specific problem pathogens must be taken into account for selection of anti-infection treatment. Many pathophysiological alterations influence the pharmacokinetics of antibiotics during sepsis. The principle of standard dosing should be abandoned and replaced by an individual treatment approach with stronger weighting of the pharmacokinetics/pharmacodynamics (PK/PD) index of the substance groups. Although this is not yet the clinical standard, prolonged (or continuous) infusion of beta-lactam antibiotics and therapeutic drug monitoring (TDM) can help to achieve defined PK targets. Prolonged infusion is sufficient without TDM but for continuous infusion TDM is basically necessary. A further argument for individual PK/PD-oriented antibiotic approaches is the increasing number of infections due to multidrug resistant pathogens (MDR) in the intensive care unit. For effective treatment antibiotic stewardship teams (ABS team) are becoming more established. Interdisciplinary cooperation of the ABS team with infectiologists, microbiologists and clinical pharmacists leads not only to a rational administration of antibiotics but also has a positive influence on the outcome. The gold standards for pathogen detection are still culture-based detection and microbiological resistance testing for the various antibiotic groups. Despite the rapid investigation time, novel polymerase chain reaction (PCR)-based procedures for pathogen identification and resistance determination, are currently only an adjunct to routine sepsis diagnostics due to the limited number of studies, high costs and limited availability. In complicated septic courses with multiple anti-infective treatment or recurrent sepsis, PCR-based procedures can be used in addition to therapy monitoring and diagnostics. Novel antibiotics represent potent alternatives in the treatment of MDR infections. Due to the often defined spectrum of pathogens and the practically absent resistance, they are suitable for targeted treatment of severe MDR infections (therapy escalation).

Abstract
Accidents in which a person is run over are often associated with multiple serious injuries. Immediate bleeding control is crucial. Pressure and shear stress at the borders of subcutaneous tissue to the muscle fascia can cause hypoperfusion and the emergence of blood-filled cavities that are associated with a high risk of infection and necrosis, a so-called Morel-Lavallée lesion. Insufficient therapy can lead to local complications and furthermore to live-threatening sepsis.

Abstract
Candida species are commonly detected isolates from abdominal foci. The question remains as to who would benefit from early empiric treatment in cases of Candida peritonitis. This study collected real-life data on critically ill patients with Candida peritonitis to estimate the relevance of the chosen treatment strategy on the outcome of these patients. One hundred and thirty-seven surgical intensive care unit (ICU) patients with intra-abdominal invasive Candidiasis were included in the study. Fifty-six patients did not get any antifungal agent. Twenty-nine patients were empirically treated, and 52 patients were specifically treated. In the group without, with empiric and with specific antifungal treatment, the 30-day mortality rate was 33.9, 48.3 and 44.2 respectively. Candida albicans was the most frequently found species. Seven patients in the specific treatment group and one patient in the empiric treatment group emerged with candidaemia. Age, leucocyte count, APACHE II Score and acute liver failure were independent predictors of 30-day mortality in patients with Candida peritonitis. Not all patients with Candida peritonitis received antifungal treatment in real clinical practice. Patients with higher morbidity more often got antifungals. Early empirical therapy has not been associated with a better 30-day mortality.

Abstract
Due to the comprehensive establishment of modern techniques, tracheostomy has become a routine procedure in intensive care units (ICU). The negative effects of prolonged translaryngeal intubation on the laryngeal and tracheal mucosa up to tracheal stenosis can be reduced by tracheostomy. Furthermore, long-term ventilation is facilitated; however, there is no clear evidence on the optimal timing of tracheostomy in critically ill patients. The specific indications and contraindications of surgical as well as percutaneous tracheostomy must be strictly observed for a safe and successful intervention. Exchanging the tracheostomy tube may lead to potentially dangerous situations especially after percutaneous tracheostomy. A standardized and structured approach is therefore recommended.

It is still debated, whether breathing circuits combined with breathing system filters can be safely used for more than 1 day. The aim of this study was to evaluate the transmission risk of bacteria and also viruses via breathing circuits after extended use. METHODS The inner and outer surface of 102 breathing circuits used for 1 day and of 101 circuits used for 7 days were examined for bacteria and viruses. Additionally, 10 and 20 breathing circuits each were examined after use on patients with pulmonary virus infection and with multidrug-resistant organism (MDRO) colonisation/infection respectively. Bacteria were detected by standard microbiological procedures; PCR techniques were applied for herpes simplex virus, cytomegalovirus, influenza, parainfluenza and respiratory syncytial virus. RESULTS Endoluminal bacterial contamination of breathing circuits remained unchanged after 7-day vs. 1-day use (5.9% vs. 7.8%) [CI95%: -0.0886-0.0506, pnon-inferiority 0.0260]. Only outside surface contamination with bacteria belonging to environmental species or human flora increased (16.8 vs. 6.9%) [CI 95%: 0.0118 - 0.1876, pnon-inferiority 0.8660]. Viruses occurred on the patient side, but not in breathing circuits. No MDRO occurred in the 20 circuits after use on patients harbouring such germs. CONCLUSION Endoluminal contamination of breathing circuits with bacteria did not increase after extended use. No viruses were detected in the breathing circuits using filters. Based on our results, the extended use of ABC without exceptions appears safe, if a high level of anaesthesia workplace cleaning is secured.

Abstract
BACKGROUND The results of recent clinical studies suggest a potential benefit of peridural analgesia (PDA) during general anesthesia on long-term survival in patients after surgery for colorectal cancer. In order to test the hypothesis a meta-analysis was performed. OBJECTIVES To determine the prognostic impact of perioperative PDA on long-term survival in patients with colorectal cancer who underwent surgical resection. MATERIAL AND METHODS By searching the relevant literature (up to May 2014) a total of 5 studies were identified from a total of 608 publications and a meta-analysis was carried out. Adjusted hazard ratios (HR) with 95 % confidence intervals (CI) were used to assess the strength of associations. The random effects model was used to analyze the data and a modified forest plot was applied. Additionally, a potential publication bias was visually examined in a funnel plot. RESULTS A positive association between PDA and improved long-term survival was observed in patients who underwent surgery for colorectal cancer without metastases (HR = 0.81, 95 % CI 0.68-0.96, p = 0.055). CONCLUSION Despite a publication bias the use of PDA in patients who underwent surgery for colorectal cancer without metastases seemed to be advantageous. Randomized controlled trials are warranted to confirm the positive effects of additional PDA. The exact mechanisms of tumor suppressive effects of PDA have not yet been elucidated.
