Many patients suffer from major adverse cardiovascular events, e.g. myocardial infarction, which in the long term can result in severe limitations in routine activities. Troponin plays the central role in identifying myocardial infarction; however, interpretation after cardiac surgery is difficult due to ischemia reperfusion injury and direct surgical trauma. Thus, the distinction between procedure-related myocardial injury and additional myocardial injury due to a new event is difficult. The fourth universal definition of type 5 myocardial infarction uses the 10 × upper limit of normal (ULN) as cut-off and notably > 90% of patients after on-pump procedures exceed this cut-off. Clinical consequences are mostly unclear. The dynamics of copeptin and heart-type fatty acid binding protein (H-FABP) concentrations start very early, i.e. several hours before troponin. The characteristics of copeptin and H‑FABP might help to overcome the limitations of troponin. This short narrative review gives a concise overview on this topic. Moreover, a brief view of future perspectives in this field is given.

Mechanical circulatory support, such as left ventricular assist devices (LVAD) are becoming increasingly more important at this stage of the disease. An LVAD improves the quality of life and prolongs the lifespan. The LVAD is used as a bridge to transplantation (BTT) for patients waiting for a donor heart or as a destination therapy (DT) with no transplantation intended; nevertheless, implantation is often associated with complications and the prognosis remains unfavorable in DT cases or after transition from BTT to DT. For patients the device may be a source of physical and psychological distress and can become a burden for families and caregivers. So far it remains unclear whether LVAD treatment is an indication for concurrent palliative care. OBJECTIVE: The aim of this study was to collect the current data on the influence of palliative care in LVAD patients and to identify possible formats of palliative care in clinical practice. MATERIAL AND METHODS: In May 2020, a systematic literature search was performed using the PICOS instrument in six different databases, i.e. PubMed, Cochrane library, Google scholar, Scopus, Web of Science and Journals@Ovid. We included quantitative and qualitative studies in English and German. Case reports, comments and pediatric studies were excluded. RESULTS: A total of 21 publications from an initial number of 491 were included in this review. The integration of palliative care in the context of LVAD implantation increased the number of advance directives and documented surrogate decision makers. Studies found a positive influence of palliative care on the conditions and place of death, family involvement and symptom and pain management. Involvement in the decision-making process may improve patient selection for LVAD treatment and helps patients to make the decision on informed consent. Various formats for the integration of palliative medical concepts into LVAD treatment are reported. It is not clear when palliative care involvement should start; however, most articles support an early and continuous integration in the LVAD process. We have aggregated possible topics for palliative care consultations from a number of publications. Mutual teaching of both LVAD and palliative care teams is recommended. Integration of a dedicated LVAD palliative care specialist as part of the LVAD team can support care for patients as well as clinicians. CONCLUSION: The role of palliative care in LVAD patients in clinical practice in the German-speaking area is not standardized. Early and continuous integration of palliative care into the course of LVAD treatment can improve the quality of care. Benefits for LVAD patients, caregivers and clinicians are described. For this purpose, recommendations as well as professional training for palliative care practitioners are useful. Further studies are needed to clarify the impact of palliative care in both DT and BTT patients.

Differential diagnostics reveal an aortoesophageal fistula (AEF) as the cause of the bleeding in very few cases. Despite increasing means of diagnostics and treatment, mortality is high in patients with AEF even under maximum medical care. These are often fulminant situations with fatal outcome for the patient. We report a case that supports this observation described from previous cases and give a closer look at this rare emergency situation. A 54-year-old patient was taken to a maximum care hospital with the clinical diagnosis of upper gastrointestinal bleeding after receiving emergency medical treatment. The source of bleeding was quickly identified as an AEF following lobectomy for bronchial cancer. Despite maximum interventional intensive treatment, the patient died a few hours after hospital admission in hemorrhagic shock due to fulminant hemorrhage from the fistula.

In the emergency room other forms of immobilization are utilized as cervical collars have certain drawbacks. The present study aimed to provide preliminary data on the efficiency of immobilization in the emergency room by analyzing the residual spinal motion of the patient's head on different kinds of head rests. METHODS: In the present study biomechanical motion data of the cervical spine of a test subject were analyzed. The test subject was placed in a supine position on a mobile stretcher (Stryker M1 Roll-In System, Kalamazoo, MI, USA) wearing a cervical collar (Perfit ACE, Ballerup, Denmark). Three different head rests were tested: standard pillow, concave pillow and cavity pillow. The test subject carried out a predetermined motion protocol: right side inclination, left side inclination, flexion and extension. The residual spinal motion was recorded with wireless motion trackers (inertial measurement unit, Xsens Technologies, Enschede, The Netherlands). The first measurement was performed without a cervical collar or positioning on the pillows to measure the physiological baseline motion. Subsequently, three measurements were taken with the cervical collar applied and the pillows in place. From these measurements, a motion score was calculated that can represent the motion of the cervical spine. RESULTS: When the test subject's head was positioned on a standard pillow the physiological motion score was reduced from 69 to 40. When the test subject's head was placed on concave pillow the motion score was further reduced from 69 to 35. When the test subject's head was placed on cavity pillow the motion score was reduced from 69 to 59. The observed differences in the overall motion score of the cervical spine are mainly due to reduced flexion and extension rather than rotation or lateral inclination. CONCLUSION: The motion score of the cervical spine using motion sensors can provide important information for future analyses. The results of the present study suggest that trauma patients can be immobilized in the early trauma phase with a cervical collar and a head rest. The application of a cervical collar and the positioning on the concave pillow may achieve a good immobilization of the cervical spine in trauma patients in the early trauma phase.

To prevent this scenario a nationwide relocation concept was developed. METHODS: For the development of the concept publicly available infection rates of the leading infection authority in Germany were used. Within this concept six medical care regions (clusters) were designed around a center of maximum intensive care (ECMO option) based on the number of intensive care beds per 100,000 inhabitants. The concept describes the management structure including a structural chart, the individual tasks, the organization and the cluster assignment of the clinics. The transfers of intensive care patients within and between the clusters were recorded from 11 December 2020 to 31 January 2021. RESULT: In Germany and Baden-Württemberg, 1.5% of patients newly infected with SARS-CoV‑2 required intensive care treatment in mid-December 2020. With a 7-day incidence of 192 new infections in Germany, the hospitalization rate was 10% and 28-35% of the intensive care beds were occupied by COVID-19 patients. Only 16.8% of the intensive care beds were still available, in contrast to 35% in June 2020. The developed relocation concept has been in use in Baden-Württemberg starting from 10 December 2020. From then until 7 February 2021, a median of 24 ± 5/54 intensive care patients were transferred within the individual clusters, in total 154 intensive care patients. Between the clusters, a minimum of 1 and a maximum of 15 (median 12.5) patients were transferred, 21 intensive care patients were transferred to other federal states and 21 intensive care patients were admitted from these states. The total number of intensive care patients transferred was 261. CONCLUSION: If the number of infections with SARS-CoV‑2 increases, a nationwide relocation concept for COVID-19 intensive care patients and non-COVID-19 intensive care patients should be installed at an early stage in order not to overwhelm the capacities of hospitals. Supply regions around a leading clinic with maximum intensive care options are to be defined with a central management that organizes the necessary relocations in cooperation with regional and superregional rescue service control centers. With this concept and the intensive care transports carried out, it was possible to effectively prevent the overload of individual clinics with COVID-19 patients in Baden-Württemberg. Due to that an almost unchanged number of patients requiring regular intensive care could be treated.

Currently recommended interventions for decompression are either finger thoracostomy or needle decompression. Due to the tiny intercostal spaces, finger thoracostomy may not be feasible in small children and surgical preparation may be necessary. In needle decompression, the risk of injuring underlying vital structures is increased because of the smaller anatomic structures. As most emergency physicians do not regularly work in pediatric trauma care, decompression of tension pneumothorax is associated with significant uncertainty; however, in this rare emergency situation, consistent and goal-oriented action is mandatory and lifesaving. An assessment of pre-existing experience and commonly used techniques therefore seems necessary to deduce the need for future education and training. OBJECTIVE: In this study an online survey was created to evaluate the experience and the favored prehospital treatment of tension pneumothorax in children among German emergency physicians. MATERIAL AND METHODS: An online survey was conducted with 43 questions on previous experience with tension pneumothorax in children, favored decompression technique and anatomical structures in different age groups. Surveyed were the emergency physicians of the ground-based emergency medical service of the University Medical Center Mannheim, the German Air Rescue Service (DRF) and the pediatric emergency medical service of the City of Munich. RESULTS: More than half of all respondents stated that there was uncertainty about the procedure of choice. Needle decompression was favored in smaller children and mini-thoracostomy in older children. In comparison with the literature, the thickness of the chest wall was mostly estimated correctly by the emergency medical physicians. The depth of the vital structures was underestimated at most of the possible insertion sites in all age groups. At the lateral insertion sites on the left hemithorax, however, the distance to the left ventricle was overestimated. The caliber of the needle selected for decompression tended to be too large, especially in younger children. CONCLUSION: Even though having interviewed an experienced group of prehospital emergency physicians, the experience in decompression of tension pneumothorax in children is relatively scant. Knowledge of chest wall thickness and depth to vital structures is sufficient, the choice of needle calibers tends to be too large but still reasonable. For many providers a large amount of uncertainty about the right choice of technique and equipment arises from the challenge of decompressing a tension pneumothorax in children and therefore further theoretical education and regular training are required for safe performance of the procedure.

In many ED CINT are treated and stabilized while in many German smaller hospitals CINT are transferred directly to the intensive care unit (ICU) without performing critical care measures in the ED. Little is known about the resuscitation room management of CINT regarding patient characteristics and outcome although bigger hospitals perform ED resuscitation of CINT in routine care. Against this background we conducted this retrospective analysis of CINT treated by an ED resuscitation room concept in a German 756 bed teaching hospital. METHODS: The collective of CINT treated within the ED resuscitation room (1 October 2018 to 31 March 2019) was analyzed after ethical approval. After each resuscitation room operation, the team leader filled out a standardized paper-based questionnaire and qualified the patient as a resuscitation room patient this way. Only patients who underwent invasive procedures and were admitted to ICU or died in the ED were included. Patient characteristics, performed critical care measures, short-term outcomes and the comparison of admission characteristics between survivors and non-survivors were evaluated. Additionally, the accordance of ED admission diagnoses and discharge diagnoses were analyzed. RESULTS: Overall, 243 of 19,854 ED patients (1.22%) were treated in the resuscitation room. After exclusion of trauma patients, 193 (0.97%) CINT were included. Overall mortality was 29% (n = 56), 24‑h mortality was 13% (n = 25). Patient characteristics (vital signs, blood gas analysis) differed significantly between survivors and nonsurvivors except for respiratory rate and pain scale. An excerpt of conducted resuscitation room measures was as follows: arterial line n = 78 (40%); noninvasive ventilation n = 60 (31%); endotracheal intubation n = 56 (29%); cardiopulmonary resuscitation n = 19 (10%), central venous line n = 8 (4%). The number of conducted measures differed between survivors and nonsurvivors (median and interquartile range, IQR): 4 (IQR 2) vs. 4 (IQR 3) p = 0.0453. The length of ED stay was 148.2 ± 202.7 min until the patient was admitted to an ICU or died within the ED. ED admission diagnoses matched with hospital discharge diagnoses in 78%. CONCLUSION: The observed mortality was high and was comparable to patient collectives with septic shock. Nonsurvivors showed significantly more impaired vital parameters and blood gas analysis parameters. Vital parameters together with blood gas analysis might enable ED risk stratification of CINT. Resuscitation room management enables immediate stabilization and diagnostic work-up of CINT even when no ICU bed is available. Furthermore, optimal allocation to specialized ICUs can probably be enabled more accurately after a first diagnostic work-up; however, although a first diagnostic work-up including laboratory tests and computed tomography in many cases was performed, ED admission and hospital discharge diagnoses matched only in 78%.

Continuity of treatment carries the risk of medical errors from declining performance capability and must be balanced against the risk of communication failure and information loss due to personnel changes. Complete intraoperative changes of anesthetists are frequently carried out in the clinical routine but possibly have the potential to negatively influence the postoperative morbidity and mortality. The relevance of anesthesiological care for the perioperative outcome also seems to vary depending on the specialist discipline involved. While standardized handover protocols seem to be only of limited effectiveness for the improvement of transfer of information, they are nevertheless a reasonable approach for optimization of interprofessional communication and reduction of treatment errors.

These critically ill patients pose special challenges to the multiprofessional treatment team and require comprehensive, interdisciplinary and interprofessional concepts. For this reason, to ensure the best possible patient care a standardized ECLS training module has been created at national specialist society level, taking emergency and intensive care management into account.
