Background: Teaching of resuscitation measures is not mandatory in all schools in Germany. It is currently limited to individual, partly mandatory projects despite a low bystander resuscitation rate. For this reason, the Ministry for Schools and Education of North Rhine-Westphalia initiated the project "Bystander resuscitation at schools in NRW" in March 2017., Objective: The aim of this work was to evaluate this project., Material and Methods: All secondary schools in North Rhine-Westphalia were invited to participate in the project. Medical partners from each administrative district took part, who carried out resuscitation training with existing concepts for teacher or student training. After a 3-year period, the evaluation was carried out using standardized questionnaires for school headmasters, teachers and students., Results: In total, more than 40,000 pupils from 249 schools in NRW could be trained in resuscitation within the project with 6 different concepts. Of the students 85% answered the questions regarding resuscitation correctly and overall felt safe in resuscitation measures. The one-off investment requirement for all schools is roughly 4-6.5 million € and around 340,000 € in each budget year., Conclusion: A legal constitution and funding are necessary for a nationwide introduction of resuscitation in schools. All established concepts are effective, therefore each school can use them exactly according to their needs, optimally in a stepped form. Training for teachers should focus on resuscitation.

Background: More and more patients are treated with antiplatelet drugs today. In this context a sufficient inhibition of platelet aggregation, on the one hand, is of essential importance to the efficiency of prophylaxis of myocardial and cerebral infarction and to avoiding thrombosis of drug-eluting stents. On the other hand, this medication can result in an increased risk of perioperative bleeding. In both situations control of the efficiency of therapy or rather the assessment of the impairment of hemostasis is of vital importance., Methods: Platelet function analyzer (PFA-100), multiple platelet function analyzer (Multiplate), and rotational thrombelastometry (ROTEM) are reliable and easy to use point-of-care (POC) devices. Since these three analyzers monitor different aspects of platelet function and have different limitations, the selection of the right test system depends on the right question., Results: PFA-100 enables a sensitive detection of von Willebrand's syndrome. Multiplate is apt to control efficiency of platelet inhibiton with acetylsalicylic acid, clopidogrel and glycoprotein IIb/IIIa receptor antagonists. ROTEM analysis offers the opportunity to assess hemostasis as a holistic system. Thereby, ROTEM analysis particularly detects hyperfibrinolysis, heparin effects, and fibrinogen-platelet interaction., Conclusion: Due to their easy handling the described POC devices are applicable to perioperative coagulation management as well as during and after coronary intervention or to monitoring of platelet function in cardiologic practice. They enable a quick assessment of platelet function and an individually guided therapy.

Background and Objective: Intra-operative bronchial suction and bronchoscopy regularly diminishes ventilation pressures and volumes and causes a leakage of narcotic gases. This study was undertaken to compare the influence of a newly-developed connecting tube with check valve on these problems., Methods: Examinations were carried out in a pressure controlled test lung with ventilation pressures between 5 and 50 mbar. Usual tube connectors and newly developed connectors with check valve were examined with respect to ventilation pressures, ventilation volumes, and leakage before and after insertion of suction catheters and bronchoscopes., Results: Using normal connectors, ventilation pressures and volumes collapsed even at lowest expiratory pressures, and significant leakage occurred. The insertion of catheters or bronchoscopes had only little beneficial effects. In contrast, the new connectors with check valve showed only small leakage, even at high ventilation pressures., Conclusion: The new tube connectors with check valve allow intra-operative suction and bronchoscopy under constant ventilation parameters with minor leakage of anaesthetic gas.
