T1 - Präklinisches Management bei Herz-Kreislauf-Stillstand – extrakorporale kardiopulmonale Reanimation JF - Der Anaesthesist N2 - Hintergrund Die Überlebenschancen nach präklinischem Herz-Kreislauf-Stillstand sind weiterhin sehr gering. Trotz intensiver Bemühungen bleibt das Outcome seit vielen Jahren weitestgehend konstant. Neue Technologien wie die extrakorporale kardiopulmonale Reanimation (eCPR) können in bestimmten Situationen möglicherweise das Überleben mit gutem neurologischen Outcome signifikant verbessern. Fragestellung Beeinflusst die sofortige Reperfusion und Reoxygenierung des Körpers mittels eCPR das Überleben nach Herz-Kreislauf-Stillstand? Bedarf es einer Erweiterung der „chain of survival“ um die eCPR? Material und Methoden Diskussion aktueller Studienergebnisse und Leitlinienempfehlungen. Ergebnisse Die Überlebensraten nach präklinischem Herz-Kreislauf-Stillstand sind weltweit seit vielen Jahren unverändert bei 10–30 %. Trotz geringer Fallzahlen zeigen neuere retrospektive Studien, dass durch die eCPR eine Verbesserung des Outcome erzielt werden kann. In selektionierten Patientenkollektiven ist ein Überleben mit gutem neurologischen Outcome von 38 % möglich. Schlussfolgerung Ob und mit welcher Lebensqualität ein Herz-Kreislauf-Stillstand überlebt werden kann, ist von vielen unterschiedlichen Faktoren abhängig. Der Faktor Zeit, also die Vermeidung einer „No-flow-Phase“ und die Reduktion der „Low-flow-Phase“, ist von zentraler Bedeutung. Durch die sofortige Wiederherstellung von Zirkulation und Sauerstoffversorgung kann durch die eCPR das Überleben signifikant verbessert werden. Große kontrollierte, randomisierte Studien hierzu fehlen jedoch bisher. N2 - Background The chances of surviving out-of-hospital cardiac arrest (OHCA) are still very low. Despite intensive efforts the outcome has remained relatively poor over many years. In specific situations, new technologies, such as extracorporeal cardiopulmonary resuscitation (eCPR) could significantly improve survival with a good neurological outcome. Objective Does the immediate restoration of circulation and reoxygenation via eCPR influence the survival rate after OHCA? Is eCPR the new link in the chain of survival? Material and methods Discussion of current study results and guideline recommendations. Results The overall survival rates after OHCA have remained at 10–30% over many years. Despite low case numbers more recent retrospective studies showed that an improved outcome can be achieved with eCPR. In selected patient collectives survival with a favorable neurological outcome is possible in 38% of the cases. Conclusion Survival after cardiac arrest and the subsequent quality of life dependent on many different factors. The time factor, i.e. the avoidance of a no-flow phase and reduction of the low-flow phase is of fundamental importance. The immediate restoration of the circulation and oxygen supply by eCPR can significantly improve survival; however, large randomized, controlled trials are currently not available.

T1 - Prevalence of pre-operative anaemia in surgical patients: a retrospective, observational, multicentre study in Germany JF - Anaesthesia N2 - Anaemia is a risk factor for several adverse postoperative outcomes. Detailed data about the prevalence of anaemia are not available over a long time-period in Germany. In this retrospective, observational, multicentre study, patients undergoing surgery in March in 2007, 2012, 2015, 2017 and 2019 were studied. The primary objective was the prevalence of anaemia at hospital admission. The secondary objectives were the association between anaemia and the number of units of red blood cells transfused, length of hospital stay and in-hospital mortality. A total of 23,836 patients were included from eight centres. The prevalence of pre-operative anaemia in patients aged ≥ 18 years decreased slightly from 37% in 2007 to 32.5% in 2019 (p = 0.01) and increased in patients aged ≤ 18 years from 18.8% in 2007 to 26.4% in 2019 (p > 0.001). The total amount of blood administered per 1000 patients decreased from 671.2 units in 2007 to 289.0 units in 2019. Transfusion rates in anaemic patients declined from 33.8% in 2007 to 19.1% in 2019 (p < 0.001) and in non-anaemic patients from 8.4% in 2007 to 3.4% in 2019 (p < 0.001). Overall, the mortality rate remained constant over the years: 2.9% in 2007, 2.1% in 2012, 2.5% in 2015, 1.9% in 2017 and 2.5% in 2019. In the presence of anaemia, mortality was significantly increased compared with patients without anaemia (OR 5.27 (95%CI 4.13–6.77); p < 0.001). Red blood cell transfusion was associated with an increased risk of mortality (OR 14.98 (95%CI 11.83–19.03); p < 0.001). Using multivariable linear regression analysis with fixed effects, we found that pre-operative anaemia (OR 2.08 (95%CI 1.42–3.05); p < 0.001) and red blood cell transfusion (OR 4.29 (95%CI 3.09–5.94); p < 0.001) were predictors of mortality but not length of stay (0.99 (95%CI 0.98–1.00) days; p = 0.12) and analysed years (2007 vs. 2019: OR 1.49 (95%CI 0.86–2.69); p = 0.07). Pre-operative anaemia affects more than 30% of surgical patients in Germany and multidisciplinary action is urgently required to reduce adverse outcomes.

T1 - Surgery in times of COVID-19 — recommendations for hospital and patient management JF - Langenbeck's Archives of Surgery N2 - Background The novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2), has escalated rapidly to a global pandemic stretching healthcare systems worldwide to their limits. Surgeonshave had to immediately react to this unprecedented clinical challenge by systematically repurposing surgical wards. Purpose To provide a detailed set of guidelines developed in a surgical ward at University Hospital Wuerzburg to safelyaccommodate the exponentially rising cases of SARS-CoV-2 infected patients without compromising the care of emergencysurgery and oncological patients or jeopardizing the well-being of hospital staff. Conclusions The dynamic prioritization of SARS-CoV-2 infected and surgical patient groups is key to preserving life whilemaintaining high surgical standards. Strictly segregating patient groups in emergency rooms, non-intensive care wards andoperating areas prevents viral spread while adequately training and carefully selecting hospital staff allow them to confidentlyand successfully undertake their respective clinical duties.
