Prevalence and severity of pediatric emergencies in a German helicopter emergency service: implications for training and service configuration.

This study primarily aims to determine the frequency of life-threatening conditions among pediatric patients served by the DRF, a German helicopter emergency service (HEMS) provider. It also seeks to explore the necessity of invasive procedures in this population, discussing the implications for HEMS crew training and service configuration based on current literature. We analyzed the mission registry from 31 DRF helicopter bases in Germany, focusing on 7954 children aged 10 or younger over a 5-year period (2014-2018). Out of 7954 identified children (6.2% of all primary missions), 2081 (26.2%) had critical conditions. Endotracheal intubation was needed in 6.5% of cases, while alternative airway management methods were rare (n = 14). Half of the children required intravenous access, and 3.6% needed intraosseous access. Thoracostomy thoracentesis and sonography were only performed in isolated cases.  Conclusions: Critically ill or injured children are infrequent in German HEMS operations. Our findings suggest that the likelihood of HEMS teams encountering such cases is remarkably low. Besides endotracheal intubation, life-saving invasive procedures are seldom necessary. Consequently, we conclude that on-the-job training and mission experience alone are insufficient for acquiring and maintaining the competencies needed to care for critically ill or injured children. What is Known: • Pediatric emergencies are relatively rare in the prehospital setting, but their incidence is higher in helicopter emergency medical services (HEMS) compared to ground-based emergency services. What is New: • On average, HEMS doctors in Germany encounter a critically ill or injured child approximately every 1.5 years in their practice, establish an IV or IO access in infants or toddlers every 2 years, and intubate an infant every 46 years. • This low frequency highlights the insufficiency of on-the-job training alone to develop and maintain pediatric skills among HEMS crews. Specific interdisciplinary training for HEMS crews is needed to ensure effective care for critically unwell pediatric patients.

Impact of COVID-19-adapted guidelines using different airway management strategies on resuscitation quality in out-of-hospital-cardiac-arrest - a randomised manikin study.

BACKGROUND: Although airway management for paramedics has moved away from endotracheal intubation towards extraglottic airway devices in recent years, in the context of COVID-19, endotracheal intubation has seen a revival. Endotracheal intubation has been recommended again under the assumption that it provides better protection against aerosol liberation and infection risk for care providers than extraglottic airway devices accepting an increase in no-flow time and possibly worsen patient outcomes. METHODS: In this manikin study paramedics performed advanced cardiac life support with non-shockable (Non-VF) and shockable rhythms (VF) in four settings: ERC guidelines 2021 (control), COVID-19-guidelines using videolaryngoscopic intubation (COVID-19-intubation), laryngeal mask (COVID-19-Laryngeal-Mask) or a modified laryngeal mask modified with a shower cap (COVID-19-showercap) to reduce aerosol liberation simulated by a fog machine. Primary endpoint was no-flow-time, secondary endpoints included data on airway management as well as the participants' subjective assessment of aerosol release using a Likert-scale (0 = no release-10 = maximum release) were collected and statistically compared. Continuous Data was presented as mean ± standard deviation. Interval-scaled Data were presented as median and Q1 and Q3. RESULTS: A total of 120 resuscitation scenarios were completed. Compared to control (Non-VF:11 ± 3 s, VF:12 ± 3 s) application of COVID-19-adapted guidelines lead to prolonged no-flow times in all groups (COVID-19-Intubation: Non-VF:17 ± 11 s, VF:19 ± 5 s;p ≤ 0.001; COVID-19-laryngeal-mask: VF:15 ± 5 s,p ≤ 0.01; COVID-19-showercap: VF:15 ± 3 s,p ≤ 0.01). Compared to COVID-19-Intubation, the use of the laryngeal mask and its modification with a showercap both led to a reduction of no-flow-time(COVID-19-laryngeal-mask: Non-VF:p = 0.002;VF:p ≤ 0.001; COVID-19-Showercap: Non-VF:p ≤ 0.001;VF:p = 0.002) due to a reduced duration of intubation (COVID-19-Intubation: Non-VF:40 ± 19 s;VF:33 ± 17 s; both p ≤ 0.01 vs. control, COVID-19-Laryngeal-Mask (Non-VF:15 ± 7 s;VF:13 ± 5 s;p > 0.05) and COVID-19-Shower-cap (Non-VF:15 ± 5 s;VF:17 ± 5 s;p > 0.05). The participants rated aerosol liberation lowest in COVID-19-intubation (median:0;Q1:0,Q3:2;p < 0.001vs.COVID-19-laryngeal-mask and COVID-19-showercap) compared to COVID-19-shower-cap (median:3;Q1:1,Q3:3 p < 0.001vs.COVID-19-laryngeal-mask) or COVID-19-laryngeal-mask (median:9;Q1:6,Q3:8). CONCLUSIONS: COVID-19-adapted guidelines using videolaryngoscopic intubation lead to a prolongation of no-flow time. The use of a modified laryngeal mask with a shower cap seems to be a suitable compromise combining minimal impact on no-flowtime and reduced aerosol exposure for the involved providers.

Incidence, characteristics and predictors of mortality following cardiac arrest in ICUs of a German university hospital: A retrospective cohort study.

BACKGROUND: Cardiac arrest in intensive care is a rarely studied type of in-hospital cardiac arrest. OBJECTIVE: This study examines the incidence, characteristics, risk factors for mortality as well as long-term prognosis following cardiac arrest in intensive care. DESIGN: Retrospective cohort study. SETTING: Five noncardiac surgical ICUs (41 surgical and 37 medical beds) at a German university hospital between 2016 and 2019. PATIENTS: Adults experiencing cardiac arrest defined as the need for chest compressions and/or defibrillation occurring for the first time on the ICU. MAIN OUTCOME MEASURES: Primary endpoint: occurrence of cardiac-arrest in the ICU. Secondary endpoints: diagnostic and therapeutic measures; risk factors and marginal probabilities of no-return of spontaneous circulation; rates of return of spontaneous circulation, hospital discharge, 1-year-survival and 1-year-neurological outcome. RESULTS: A total of 114 cardiac arrests were observed out of 14 264 ICU admissions; incidence 0.8%; 95% confidence interval (CI) 0.7 to 1.0; 45.6% received at least one additional diagnostic test, such as blood gas analysis (36%), echocardiography (19.3%) or chest x-ray (9.9%) with a resulting change in therapy in 52%, (more frequently in those with a return of spontaneous circulation vs none, P  = 0.023). Risk factors for no-return of spontaneous circulation were cardiac comorbidities (OR 5.4; 95% CI, 1.4 to 20.7) and continuous renal replacement therapy (OR 5.9; 95% CI, 1.7 to 20.8). Bicarbonate levels greater than 21 mmol 1 were associated with a higher mortality risk in combination either with cardiac comorbid-ities (bicarbonate <21 mmol I-1: 13%; 21 to 26 mmolI-1 45%; >26mmolI-1:42%)orwithaSOFA at least 2 (bicarbonate <21 mmolI-1 8%; 21 to 26 mmolI-1: 40%; >26mmolI-1: 37%). "In-hospital mortality was 78.1% (n = 89); 1-year-survival-rate was 10.5% (95% CI, 5.5 to 17.7) and survival with a good neurological outcome was 6.1% (95% CI, 2.5 to 12.2). CONCLUSION: Cardiac arrest in ICU is a rare complication with a high mortality and low rate of good neurological outcome. The development of a structured approach to resuscitation should include all available resources of an ICU and adequately consider the complete diagnostic and therapeutic spectra as our results indicate that these are still underused. The development of prediction models of death should take into account cardiac and hepatic comorbidities, continuous renal replacement therapy, SOFA at least 2 before cardiac arrest and bicarbonate level. Further research should concentrate on identifying early predictors and on the prevention of cardiac arrest in ICU.

Blood Product Supply for a Helicopter Emergency Medical Service.

BACKGROUND: Long patient transport times to trauma centers are a well-known problem in sparsely populated regions with a low hospital density. Transfusion of red blood cell concentrates (RBC) and plasma improves outcome of trauma patients with severe bleeding. Helicopter emergency services (HEMS) are frequently employed to provide early advanced medical care and to reduce time to hospital admission. Supplying HEMS with blood products allows prehospital transfusion and may help to prevent exsanguination or prolonged hemorrhagic shock. We have investigated the maintenance of blood product quality under air transport conditions and the logistical steps to introduce a HEMS blood depot into routine practice. METHODS: A risk analysis was performed and a validation plan developed. A special, commercially available transport container for blood products was identified. Maintenance of temperature conditions between 2 and 6°C in the box were monitored at ambient temperatures up to 35°C over 48 h. Quality of blood products before and after helicopter air transport were evaluated including (1) for RBCs: hemoglobin, hematocrit, hemolysis rate; (2) for thawed plasma: aPTT, INR, single clotting factor activities. The logistics for blood supply of the regional HEMS were developed by the transfusion service of the Greifswald University Hospital in collaboration with the in-hospital transport team, the HEMS team, and the HEMS operator. RESULTS: The transport container maintained a temperature below 6°C up to 36 h at 35°C ambient temperature. Vibration during helicopter operation did not impair quality of RBC and thawed plasma. To provide blood products for HEMS at least two transport containers and an additional set of cooling tiles is needed as the cooling tiles need a special temperature priming over 20 h. The two boxes were used at alternate days. To reduce wastage, RBCs and thawed plasmas were exchanged every fourth day and reintegrated into the blood bank inventory for further in-hospital use. CONCLUSIONS: Supplying HEMS with RBCs and plasma is feasible. Helicopter transport has no negative impact on blood product quality. The logistic challenges require close collaboration between the HEMS team and the blood transfusion service.

[Cardiac arrest under special circumstances]. / Kreislaufstillstand unter besonderen Umständen: Leitlinien des European Resuscitation Council 2021.

These guidelines of the European Resuscitation Council (ERC) Cardiac Arrest under Special Circumstances are based on the 2020 International Consensus on Cardiopulmonary Resuscitation Science with Treatment Recommendations. This section provides guidelines on the modifications required for basic and advanced life support for the prevention and treatment of cardiac arrest under special circumstances; in particular, specific causes (hypoxia, trauma, anaphylaxis, sepsis, hypo-/hyperkalaemia and other electrolyte disorders, hypothermia, avalanche, hyperthermia and malignant hyperthermia, pulmonary embolism, coronary thrombosis, cardiac tamponade, tension pneumothorax, toxic agents), specific settings (operating room, cardiac surgery, cardiac catheterization laboratory, dialysis unit, dental clinics, transportation [in-flight, cruise ships], sport, drowning, mass casualty incidents), and specific patient groups (asthma and chronic obstructive pulmonary disease, neurological disease, morbid obesity, pregnancy).

Cardiac Arrest in the Operating Room: Part 2-Special Situations in the Perioperative Period.

As noted in part 1 of this series, periprocedural cardiac arrest (PPCA) can differ greatly in etiology and treatment from what is described by the American Heart Association advanced cardiac life support algorithms, which were largely developed for use in out-of-hospital cardiac arrest and in-hospital cardiac arrest outside of the perioperative space. Specifically, there are several life-threatening causes of PPCA of which the management should be within the skill set of all anesthesiologists. However, previous research has demonstrated that continued review and training in the management of these scenarios is greatly needed and is also associated with improved delivery of care and outcomes during PPCA. There is a growing body of literature describing the incidence, causes, treatment, and outcomes of common causes of PPCA (eg, malignant hyperthermia, massive trauma, and local anesthetic systemic toxicity) and the need for a better awareness of these topics within the anesthesiology community at large. As noted in part 1 of this series, these events are always witnessed by a member of the perioperative team, frequently anticipated, and involve rescuer-providers with knowledge of the patient and the procedure they are undergoing or have had. Formulation of an appropriate differential diagnosis and rapid application of targeted interventions are critical for good patient outcome. Resuscitation algorithms that include the evaluation and management of common causes leading to cardiac in the perioperative setting are presented. Practicing anesthesiologists need a working knowledge of these algorithms to maximize good outcomes.

Cardiac Arrest in the Operating Room: Resuscitation and Management for the Anesthesiologist: Part 1.

Cardiac arrest in the operating room and procedural areas has a different spectrum of causes (ie, hypovolemia, gas embolism, and hyperkalemia), and rapid and appropriate evaluation and management of these causes require modification of traditional cardiac arrest algorithms. There is a small but growing body of literature describing the incidence, causes, treatments, and outcomes of circulatory crisis and perioperative cardiac arrest. These events are almost always witnessed, frequently known, and involve rescuer providers with knowledge of the patient and their procedure. In this setting, there can be formulation of a differential diagnosis and a directed intervention that treats the likely underlying cause(s) of the crisis while concurrently managing the crisis itself. Management of cardiac arrest of the perioperative patient is predicated on expert opinion, physiologic rationale, and an understanding of the context in which these events occur. Resuscitation algorithms should consider the evaluation and management of these causes of crisis in the perioperative setting.

A comparison of Simplified Acute Physiology Score II and Sepsis-related Organ Failure Assessment Score for prediction of mortality after Intensive Care Unit cardiac arrest.

BACKGROUND: This study investigates the predictive value and suitable cutoff values of the Sepsis-related Organ Failure Assessment Score (SOFA) and Simplified Acute Physiology Score II (SAPS-II) to predict mortality during or after Intensive Care Unit Cardiac Arrest (ICU-CA). METHODS: In this secondary analysis the ICU database of a German university hospital with five ICU was screened for all ICU-CA between 2016-2019. SOFA and SAPS-II were used for prediction of mortality during ICU-CA, hospital-stay and one-year-mortality. Receiver operating characteristic curves (ROC), area under the ROC (AUROC) and its confidence intervals were calculated. If the AUROC was significant and considered "acceptable," cutoff values were determined for SOFA and SAPS-II by Youden Index. Odds ratios and sensitivity, specificity, positive and negative predictive values were calculated for the cutoff values. RESULTS: A total of 114 (78 male; mean age: 72.8±12.5 years) ICU-CA were observed out of 14,264 ICU-admissions (incidence: 0.8%; 95% CI: 0.7-1.0%). 29.8% (N.=34; 95% CI: 21.6-39.1%) died during ICU-CA. SOFA and SAPS-II were not predictive for mortality during ICU-CA (P>0.05). Hospital-mortality was 78.1% (N.=89; 95% CI: 69.3-85.3%). SAPS-II (recorded within 24 hours before and after ICU-CA) indicated a better discrimination between survival and death during hospital stay than SOFA (AUROC: 0.81 [95% CI: 0.70-0.92] vs. 0.70 [95% CI: 0.58-0.83]). A SAPS-II-cutoff-value of 43.5 seems to be suitable for prognosis of hospital mortality after ICU-CA (specificity: 87.5%, sensitivity: 65.6%; SAPS-II>43.5: 87.5% died in hospital; SAPS-II<43.5: 65.6% survived; odds ratio:13.4 [95% CI: 3.25-54.9]). Also for 1-year-mortality (89.5%; 95% CI: 82.3-94.4) SAPS-II showed a better discrimination between survival and death than SOFA: AUROC: 0.78 (95% CI: 0.65-0.91) vs. 0.69 (95% CI: 0.52-0.87) with a cutoff value of the SAPS-II of 40.5 (specificity: 91.7%, sensitivity: 64.3%; SAPS-II>40.5: 96.4% died; SAPS-II<40.5: 42.3% survived; odd ratio: 19.8 [95% CI: 2.3-168.7]). CONCLUSIONS: Compared to SOFA, SAPS-II seems to be more suitable for prediction of hospital and 1-year-mortality after ICU-CA.

Effects of COVID-19 on a mature citizen first responder system in the German district of Gütersloh: an observational study.

BACKGROUND: The aim of this study was to examine the impact of COVID-19 on the response rate of community-first-responders (CFR) and other out-of-hospital-cardiac-arrest (OHCA) outcomes using the smartphone-first-responder-system (SFRS) "Mobile Retter." METHODS: All adult non-traumatic OHCA in the district of Gütersloh between 01.01.2018-31.12.2021 were included. Periods of interest were 1) prior to the first COVID-19-lockdown; to 2) both lockdowns; and 3) the time in between, as well as after the COVID-19-lockdowns (pre-COVID-19, COVID-19-lockdown and COVID-19-pandemic respectively). The primary outcome was the CFR response rate defined as proportion of CFR alerts that were accepted by a CFR and in which at least one CFR arrived on scene of the emergency out of all CFR alerts. Secondary outcomes included the rate of CFR alerts, defined as proportion of OHCA to which CFR were summoned by the emergency medical dispatcher, as well as the rate of return-of-spontaneous-circulation (ROSC) and rate of survival until hospital discharge. We also examined the incidence COVID-19-infection of CFR in context of the SFRS. RESULTS: A total of 1064 OHCA-patients (mean age: 71.4±14.5 years; female: 33.8%) were included in the study (Pre-COVID-19: 539; COVID-19-lockdown: 109; COVID-19-pandemic: 416). The response rate was 64.0% (pre-COVID-19: 58.7%; COVID-19-lockdown: 63.5%; COVID-19-pandemic: 71.8%, P=0.002 vs. pre-COVID-19). The alert rate was 52.7% (pre-COVID-19: 56.2%; COVID-19-lockdown: 47.7%, P=0.04 vs. Pre-COVID-19; COVID-19-Pandemic: 49.5%, P=0.02 vs. pre-COVID-19). The ROSC-rate was 40.4% (pre-COVID-19: 41.0%; COVID-19-lockdown: 33.9%; COVID-19-pandemic: 41.4%) and hospital discharge rate 31.2% (Pre-COVID-19: 33.0%; COVID-19-lockdown: 36.8%; COVID-19-pandemic: 28.7%). The use of CFR was associated with favorable effects in terms of hospital admission (odds ratio [OR]: 0.654 (CI95: 0.444-0.963), P=0.03), hospital discharge (OR: 2.343 (CI95: 1.002-5.475), P=0.04). None of the CFR became infected with COVID-19. CONCLUSIONS: "Mobile-Retter" was associated with high response rates, improved outcome in OHCA patients and no COVID-19-infections of CFR during the COVID-19-pandemic and -lockdowns.

Midazolam for Post-Arrest Sedation in Pre-Hospital Emergency Care.

BACKGROUND: An out-of-hospital cardiac arrest (OHCA) with return of spontaneous circulation (ROSC) may need to be treated with airway management, emergency ventilation, invasive interventions, and post-arrest sedation. We investigated the influence of the use of midazolam for post-arrest sedation on achieving postresuscitation care targets and the associated risk of hemodynamic complications. METHODS: All emergency rescue missions of the Dresden, Gütersloh, and Lippe medical rescue services in the years 2019-2021 were reviewed to identify adult patients who had OHCA, unconsciousness, and sustained ROSC with spontaneous circulation until arrival at the hospital; the findings were supplemented with data from the German Resuscitation Registry. Patients who received midazolam (alone or in combination with other anesthetic agents) for post-arrest sedation were compared with those who did not. The endpoints were the regaining of a systolic blood pressure ≥ 100 mmHg, end-tidal pCO2 35-45 mmHg, and oxygen saturation (SpO2) 94-98%. A propensity score analysis was used to adjust for age, sex, and variables potentially affecting hemodynamic status or the targets for oxygenation and ventilation. RESULTS: There were 2335 cases of OHCA among 391 305 emer - gency rescue missions. 571 patients had ROSC before arrival in the hospital (24.5%; female, 33.6%; age, 68 ± 14 years). Of the 395 among them (69.2%) who were treated with postarrest sedation, 249 (63.0%) received midazolam. Patients who received midazolam reached the guideline- recommended targets for oxygenation, ventilation, and blood pressure more frequently than those who were not sedated: the respective odds ratios and 95% confidence intervals were 2.00 [1.20; 3.34], 1.57 [0.99; 2.48], and 1.41 [0.89; 2.21]. CONCLUSION: The pre-hospital administration of midazolam leads to more frequent pre-hospital attainment of the oxygenation and ventilation targets in post-resuscitation care, without any evidence of an elevated risk of hemodynamic complications.

Prehospital anesthesia in postcardiac arrest patients: a multicenter retrospective cohort study.

BACKGROUND: Currently, the data regarding the impact of prehospital postcardiac arrest anesthesia on target hemodynamic and ventilatory parameters of early postresuscitation care and recommendations on its implementation are rare. The present study examines the incidence and impact of prehospital postcardiac arrest anesthesia on hemodynamic and ventilatory target parameters of postresuscitation care. METHODS: In this multicentre observational study between 2019 and 2021 unconscious adult patients after out-of-hospital-cardiac arrest with the presence of a return-of-spontaneous circulation until hospital admission were included. Primary endpoint was the application of postarrest anesthesia. Secondary endpoints included the medication group used, predisposing factors to its implementation, and its influence on achieving target parameters of postresuscitation care (systolic blood pressure: ≥ 100 mmHg, etCO2:35-45 mmHg, SpO2: 94-98%) at hospital handover. RESULTS: During the study period 2,335 out-of-hospital resuscitations out of 391,305 prehospital emergency operations (incidence: 0.58%; 95% CI 0.54-0.63) were observed with a return of spontaneous circulation to hospital admission in 706 patients (30.7%; 95% CI 28.8-32.6; female: 34.3%; age:68.3 ± 14.2 years). Postcardiac arrest anesthesia was performed in 482 patients (68.3%; 95% CI 64.7-71.7) with application of hypnotics in 93.4% (n = 451), analgesics in 53.7% (n = 259) and relaxants in 45.6% (n = 220). Factors influencing postcardiac arrest sedation were emergency care by an anesthetist (odds ratio: 2.10; 95% CI 1.34-3.30; P < 0.001) and treatment-free interval ≤ 5 min (odds ratio: 1.59; 95% CI 1.01-2.49; P = 0.04). Although there was no evidence of the impact of performing postcardiac arrest anesthesia on achieving a systolic blood pressure ≥ 100 mmHg at the end of operation (odds ratio: 1.14; 95% CI 0.78-1.68; P = 0.48), patients with postcardiac arrest anesthesia were significantly more likely to achieve the recommended ventilation (odds ratio: 1.59; 95% CI 1.06-2.40; P = 0.02) and oxygenation (odds ratio:1.56; 95% CI 1.04-2.35; P = 0.03) targets. Comparing the substance groups, the use of hypnotics significantly more often enabled the target values for etCO2 to be reached alone (odds ratio:2.79; 95% CI 1.04-7.50; P = 0.04) as well as in combination with a systolic blood pressure ≥ 100 mmHg (odds ratio:4.42; 95% CI 1.03-19.01; P = 0.04). CONCLUSIONS: Postcardiac arrest anesthesia in out-of-hospital cardiac arrest is associated with early achievement of respiratory target parameters in prehospital postresuscitation care without evidence of more frequent hemodynamic complications.

The European Trauma Course: Transforming systems through training.

The European Trauma Course (ETC) exemplifies an innovative approach to multispecialty trauma education. This initiative was started as a collaborative effort among the European Society for Emergency Medicine, the European Society for Trauma and Emergency Surgery, and the European Society of Anaesthesiology under the auspices of the European Resuscitation Council. With the robust support of these societies, the project has evolved into the independent European Trauma Course Organisation. Over the past 15 years, the ETC has transcended traditional training by integrating team dynamics and non-technical skills into a scenario-based simulation course, helping to shape trauma care practice and education. A distinctive feature of the ETC is its training of doctors and allied healthcare professionals, fostering a collaborative and holistic approach to trauma care. The ETC stands out for its unique team-teaching approach, which has gained widespread recognition as the standard for in-hospital trauma care training not only in Europe but also beyond. Since its inception ETC has expanded geographically from Finland to Sudan and from Brazil to the Emirates, training nearly 20,000 healthcare professionals and shaping trauma care practice and education across 25 countries. Experiencing exponential growth, the ETC continues to evolve, reflecting its unmet demand in trauma team education. This review examines the evolution of the ETC, its innovative team-teaching methodology, national implementation strategies, current status, and future challenges. It highlights its impact on trauma care, team training, and the effect on other life support courses in various countries.

From tradition to innovation: a comparison of the traditional 4-step approach versus a blended learning modification for technical skills teaching.

BACKGROUND: This experimental study was performed to evaluate the role of blended learning for technical skill teaching on the European Trauma Course (ETC). While online modules are extensively used for theoretical teaching, their role in skills training remains less well explored. The ETC currently relies on the established 4-step technique for teaching technical skills. However, the required large cohort of skilled instructors and the time intensity prove increasingly challenging in a current climate of staff shortages and funding constraints. This study assesses if blended learning, combining pre-course online elements with face-to-face training matches the effectiveness of the traditional 4-step approach whilst being more time-efficient. METHODS: In a randomised, multi-centre trial, the conventional face-to-face 4-step technique for teaching a skill of medium complexity, the application of a pelvic binder, was compared with an innovative blended approach. It was hypothesised that the blended approach was non-inferior for skill performance measured after the teaching session and after two days (skill retention) with the time needed for teaching and student/teacher satisfaction as secondary outcomes. RESULTS: Ninety participants, divided into 44 traditional and 46 blended method students, were analysed. Independent-samples t-test showed no significant difference in performance scores and non-inferiority of the blended approach with a half of one standard deviation margin. A statistically significant difference in mean retention scores favored the blended approach. A Mann-Whitney U Test revealed no significant difference in candidate satisfaction levels but a statistically significant difference in instructors' satisfaction levels in favour of the blended approach. Analysis with Welch' t-test demonstrated that the face-to-face teaching time needed for the blended approach was significantly shorter (by 6 min). CONCLUSIONS: The integration of a blended approach with the 4-step technique for teaching pelvic binder application in the ETC streamlined teaching without compromising skill acquisition quality. This innovative approach addresses traditional limitations and shows promise in adapting medical education to modern learning and teaching demands. We suggest that blended learning could also be applied for other skills taught on life support courses.

State of implementation of the Corona-Virus-Disease-2019 resuscitation guidelines : An online-based survey one year after publication in Germany.

BACKGROUND: The present study evaluated the implementation of the European Resuscitation Council Corona-Virus-Disease 2019 (COVID-19) resuscitation guidelines in Germany 1 year after publication. AIM OF THE WORK: To evaluate the practical implementation of the COVID-19 resuscitation guidelines in Germany one year after their publication. MATERIAL AND METHODS: In an online survey between April and May 2021 participants were asked about awareness of COVID-19 resuscitation guidelines, corresponding training, the resuscitation algorithm used and COVID-19 infections of emergency medicine personnel associated with COVID-19 resuscitation. RESULTS: A total of 961 (8%) of the 11,000 members took part in the survey and 85% (818/961) of questionnaires were fully completed. While 577 (70%) of the respondents were aware of the COVID-19 guidelines, only 103 (13%) had received respective training. A specific COVID-19 resuscitation algorithm was used by 265 respondents (32%). Adaptations included personal protective equipment (99%), reduction of staff caring for the patient, or routine use of video laryngoscopy for endotracheal intubation (each 37%), securing the airway before rhythm analysis (32%), and pausing chest compressions during endotracheal intubation (30%). Respondents without a specific COVID-19 resuscitation algorithm were more likely to use mouth-nose protection (47% vs. 31%; p < 0.001), extraglottic airway devices (66% vs. 55%; p = 0.004) and have more than 4 team members close to the patient (45% vs. 38%; p = 0.04). Use of an Filtering-Face-Piece(FFP)-2 or FFP3 mask (89% vs. 77%; p < 0.001; 58% vs. 70%; p ≤ 0.001) or performing primary endotracheal intubation (17% vs. 31%; p < 0.001) were found less frequently and 9% reported that a team member was infected with COVID-19 during resuscitation. CONCLUSION: The COVID-19 resuscitation guidelines are still insufficiently implemented 1 year after publication. Future publication strategies must ensure that respective guideline adaptations are implemented in a timely manner.
