Outcomes of patients with CA treated at a specialized ED have improved significantly within the last 20 years. Improvements in every link in the chain of survival were noted.
BackgroundCardio-pulmonary-resuscitation (CPR) training starting at the age of 12 years is recommended internationally. Training younger children is not recommended because young children lack the physical ability to perform adequate CPR and discouragement to perform CPR later is apprehended. The aim of this study was to answer the following questions: Are younger children discouraged after CPR training? Is discouragement caused by their lack in physical ability to perform adequate chest compressions on a standard manikin and would the use of manikins with a reduced resistance affect their motivation or performance?MethodsWe investigated the motivation and CPR performance of children aged 8–13 years after CPR training on manikins of different chest stiffness in a prospective, randomized, single-blind, controlled trial. 322 children underwent randomization and received 30 minutes CPR training in small groups at school. We used two optically identical resuscitation manikins with different compression resistances of 45kg and 30kg. Motivation was assessed with a self-administered questionnaire. Performance was measured with the Resusci®Anne SkillReporter™.FindingsMotivation after the training was generally high and there was no difference between the two groups in any of the questionnaire items on motivation: Children had fun (98 vs. 99%; P = 0.32), were interested in the training (99 vs. 98%; P = 0.65), and were glad to train resuscitation again in the future (89 vs. 91%; P = 0.89). CPR performance was generally poor (median compression score (8, IQR 1–45 and 29, IQR 11–54; P<0.001) and the mean compression depth was lower in the 45kg-resistance than in the 30kg-resistance group (33±10mm vs. 41±9; P<0.001).ConclusionsCompression resistances of manikins, though influencing CPR performance, did not discourage 8 to 13 year old children after CPR training. The findings refute the view that young children are discouraged when receiving CPR training even though they are physically not able to perform adequate CPR.
BACKGROUND
There is an increasing use of extracorporeal life support in refractory cardiac arrest. Recent studies highlighted the importance of an early and accurate patient selection for this invasive procedure.
OBJECTIVES
The aim of this study was to retrospectively validate a six-criteria-screening-checklist (witnessed collapse, bystander-cardiopulmonary resuscitation/first medical contact <5 min, shockable, age <70 years, end tidal carbon dioxide >14 mmHg and pupils not anisocoric/distorted/mydriatic) as an early screening tool in patients treated with extracorporeal cardiopulmonary resuscitation (eCPR) at the emergency department.
DESIGN
Retrospective observational study.
SETTING/PATIENTS
All patients at least 18 years of age with nontraumatic cardiac arrest and without return of spontaneous circulation before eCPR treatment at our department between January 2013 and December 2018 were included in this retrospective observational study.
INTERVENTION
No specific intervention was set in this observational study.
MAIN OUTCOME MEASURES
Primary outcome was the rate of patients who fulfilled all criteria, secondary outcome was 30-day and 6-month survival in accordance with the criteria.
RESULTS
Overall, data from a total of 92 patients were eligible for analyses. Out of these, 27 patients (29%) met all criteria. Patients, who fulfilled all criteria, showed significantly higher odds for 30-day survival [OR 6.0 (95% CI 1.78 to 20.19)] P
= 0.004. Patients, who did not fulfil all criteria, showed significantly higher rates of early mortality after eCPR initiation [OR 4.57 (95% CI 1.69 to 12.37)] P
= 0.003.
CONCLUSION
Patients fulfilling all inclusion criteria showed higher rates of survival after eCPR. Our results affirm that there is a possibility and even an obvious necessity for early patient selection based on standardised criteria before eCPR treatment. Large randomised trials are urgently needed to answer this question accurately.
Background: The COVID-19 pandemic has resulted in the suspension of the entire teaching program at the Medical University of Vienna till the end of the summer semester. As the department that is responsible for emergency medicine teaching, we adapted the program to continue the courses and maintain the learning progress. Our objective is to evaluate the number of courses conducted and report the methods used.Methods: Teaching was measured as credit hours per week (CHW) in accordance with the university's prospectus. One CHW represents 15 academic hours (45 min) in one semester. Webinars were conducted using the CISCO Webex Events ® , Webex Training , and ZOOM ® . The Moodle ® was utilized for resuscitation courses.Results: Courses and clerkships equivalent to 80.2 out of 101.4 CHW (79.1%) could be held during the ongoing crisis in the summer semester. Courses in the winter semester were all completed. In the human medicine curriculum, 73.7 out of 94.9 CHW (77.7%) could be conducted. In the case of emergency lectures for the dentistry curriculum, all courses were conducted through webinars (6.5 CHW, 100%). After calculating the exact number of students in each class, it has been determined that courses and clerkships equivalent to 78.7% could be conducted.
Conclusion:Despite the challenge of preparing for the treatment of numerous patients during the ongoing pandemic, we could shoulder a majority of our teaching responsibilities. Although sufficient skill training could not be imparted under these circumstances, we could provide sufficient theoretical knowledge to allow students to continue studies.
Background:Extracorporeal life support (ECLS) for cardiopulmonary resuscitation (CPR) may increase end organ perfusion and thus survival when conventional CPR fails. The aim was to investigate, if after ventricular fibrillation cardiac arrest in rodents ECLS improves outcome compared with conventional CPR.Methods:In 24 adult male Sprague–Dawley rats (460–510 g) resuscitation was started after 10 min of no-flow with ECLS (consisting of an open reservoir, roller pump, and membrane oxygenator, connected to cannulas in the jugular vein and femoral artery, n = 8) or CPR (mechanical chest compressions plus ventilations, n = 8) and compared with a sham group (n = 8). After return of spontaneous circulation (ROSC), all rats were maintained at 33°C for 12 h. Survival to 14 days, neurologic deficit scores and overall performance categories were assessed.Results:ECLS leads to sustained ROSC in 8 of 8 (100%) and neurological intact survival to 14 days in 7 of 8 rats (88%), compared with 5 of 8 (63%) and 1 of 8 CPR rats. The median survival time was 14 days (IQR: 14–14) in the ECLS and 1 day (IQR: 0 to 5) for the CPR group (P = 0.004).Conclusion:In a rat model of prolonged ventricular fibrillation cardiac arrest, ECLS with mild hypothermia produces 100% resuscitability and 88% long-term survival, significantly better than conventional CPR.
