TY - THES A1 - Vollmer, Tina Alexandra T1 - Die Untersuchung innerklinischer Herz-Kreislaufstillstände mit Gebrauch eines AED am Beispiel eines Universitätsklinikums - eine retrospektive Beobachtungsstudie T1 - The investigation of in-hospital cardiovascular arrest events with the use of Automated External Defibrillators on the example of a University Hospital - a retrospective observational study N2 - Hintergrund: Patienten, die einen Herz-Kreislaufstillstand erleiden haben eine geringere Überlebensrate wenn Reanimationsmaßnahmen nicht suffizient durchgeführt werden. Innerhalb einer Klinik sind die Ersthelfer meistens Mitarbeiter der Pflege, die nur über geringe Kenntnisse in der Herzrhythmusanalyse verfügen. In solchen Fällen kann ein Automatischer Externer Defibrillator (AED) hilfreich sein um die Durchführung der Reanimationsmaßnahmen zu verbessern. Aus diesem Grund wurde im Jahr 2007 das AED-Programm am Universitätsklinikum Würzburg (Deutschland) eingeführt. Ziel dieser Studie war die Auswirkungen der Automatischen Externen Defibrillatoren auf die innerklinischen Herz-Kreislaufstillstände und die Reanimationsmaßnahmen zu untersuchen. Methodik: Die Datenerfassung erfolgte im Rahmen von Qualitätssicherungsmaßnahmen am Universitätsklinikum Würzburg. Daten zur Thoraxkompressionstiefe (CCD), Thoraxkompressionsfrequenz (CCR) und zur No-Flow-Fraktion (NFF), zum Zeitintervall vom Einschalten des AED bis zur ersten Thoraxkompression (TtC), zum Zeitintervall vom Einschalten des AED bis zur ersten Schockabgabe (TtS) und zum Zeitintervall nach Schockabgabe bis zum Beginn der Thoraxkompression (TtCS) wurden mit Hilfe der aufgezeichneten Daten des AED ausgewertet. Ein Fragebogen wurde von den Ersthelfern ausgefüllt. Ergebnisse: Zwischen 2010 und 2012 wurden insgesamt 359 innerklinische Notrufe registriert. Davon waren 53 Herz-Kreislaufstillstände mit Gebrauch eines AED, in 46 Fällen waren vollständige Datensätze vorhanden. Die mittlere CCD lag bei 5,5 +/- 1 cm, die mittlere CCR betrug 107 +/- 11/min. Die NFF lag bei 41%. Die TtC lag bei 34 (32-52) Sekunden (Median und IQR), die TtS betrug 30 (28-32) Sekunden (Median und IQR) und die TtCS lag bei 4 (3-6) Sekunden (Median und IQR). 21 Patienten (45%) erreichten einen ROSC, 8 Patienten (17%) verstarben vor Ort und 17 Patienten (37%) wurden unter laufender Reanimation auf eine Intensivstation (ITS) verlegt. Zusammenfassung: Sowohl die TtC als auch die TtS verdeutlichen die durch den Anwender verursachte Zeitverzögerung. Diese Zeitintervalle können erheblich verkürzt werden sofern der Anwender die Sprachanweisungen des AED unterbricht und die Paddles direkt auf dem Thorax des Patienten anbringt. Der AED schaltet unmittelbar in den Analysemodus. Häufige Schulungen der Mitarbeiter und regelmäßig angepasste Schulungsinhalte sind notwendig um den Umgang mit dem AED und somit die Reanimationsmaßnahmen zu verbessern. N2 - Background: Patients who suffer from cardiovascular arrest have a lower survival rate if the resuscitation performance is poor. First responders in the in-hospital setting are usually nursing staff who have only little knowledge of cardiac rhythm analysis. In these cases an Automated External Defibrillator (AED) may be useful to improve the resuscitation performance. For this reason an AED-program was started at the Wuerzburg University Hospital (Germany) in 2007. The purpose of this study was to examine the impact of Automated External Defibrillators on the implementation of resuscitation performance. Methods: The data was collected as part of the quality management of the Wuerzburg University Hospital. To record the quality of the resuscitation performance the chest compression depth (CCD), chest compression rate (CCR), the no flow fraction (NFF), the time interval from starting the AED to the first compression (TtC), time interval from starting the AED to the first shock (TtS) an the post shock pause (TtCS) were analysed by AED recorded data. A questionnaire was completed by the first responders. Results: From 2010 and 2012 a total of 359 in-hospital emergency calls were recorded. Of these 53 were cardiac arrest with the use of an AED. Full records were available in 46 cases. The CCD was 5.5 +/- 1 cm, the CCR was 107 +/- 11/min. The no flow fraction (NFF) was charged as 41%. The TtC was 34 (32-52) seconds (median and IQR), the TtS was 30 (28-32) seconds (median and IQR) and the TtCS was 4 (3-6) seconds (median and IQR). 21 patients (45%) achieved ROSC, 8 patients (17%) died on scene and 17 patients (37%) were transferred to an Intensive Care Unit (ICU) under ongoing resuscitation. Conclusion: Both TtC and TtS showed the time loss caused by the AED-user. These time intervals can be considerably shortened if the user interrupts the voice prompts given by the AED by placing the electrode-paddles directly on the patient’s thorax. The AED then immediately switches to the analysing mode. Frequent training and adapted training contents are necessary to improve the handling of the AED and the resuscitation performance.

In In-hospital settings the first responders on scene are usually nursing staff without rhythm analysing skills. In such cases Automated External Defibrillators (AED) might help guiding resuscitation performance. At the Wuerzburg University Hospital (Germany) an AED-program was initiated in 2007. Aim of the presented study was to monitor the impact of Automated External Defibrillators on the management of in-hospital cardiac arrest events. Methods The data acquisition was part of a continuous quality improvement process of the Wuerzburg University Hospital. For analysing the CPR performance, the chest compression rate (CCR), compression depth (CCD), the no flow fraction (NFF), time interval from AED-activation to the first compression (TtC), the time interval from AED-activation to the first shock (TtS) and the post schock pause (TtCS) were determined by AED captured data. A questionnaire was completed by the first responders. Results From 2010 to 2012 there were 359 emergency calls. From these 53 were cardiac arrests with an AED-application. Complete data were available in 46 cases. The TtC was 34 (32–52) seconds (median and IQR).The TtS was 30 (28–32) seconds (median and IQR) . The TtCS was 4 (3–6) seconds (median and IQR) . The CCD was 5.5 ± 1 cm while the CCR was 107 ± 11/min. The NFF was calculated as 41 %. ROSC was achieved in 21 patients (45 %), 8 patients (17 %) died on scene and 17 patients (37 %) were transferred under ongoing CPR to an Intensive Care Unit (ICU). Conclusion The TtS and TtC indicate that there is an AED-user dependent time loss. These time intervals can be markedly reduced, when the user is trained to interrupt the AED’s “chain of advices” by placing the electrode-paddles immediately on the patient’s thorax. At this time the AED switches directly to the analysing mode. Intensive training and adaption of the training contents is needed to optimize the handling of the AED in order to maximize its advantages and to minimize its disadvantages.
