Acute respiratory distress syndrome (ARDS) is defined as an acute inflammatory syndrome leading to increased pulmonary capillary leakage and subsequent interstitial and alveolar pulmonary edema. Hypoxia is the predominant symptom. The definition of ARDS comprises acute onset, bilateral patchy infiltration on chest X‑ray and a reduction of the ratio of arterial partial pressure of oxygen (PaO) to the fraction of inspired oxygen (FiO), which also determines the classification into mild (≤ 300), moderate (≤ 200) and severe (≤ 100) ARDS. Treating the underlying cause is the only causal treatment measure. The aim of adjunctive therapy is the maintenance of life or organ functions by ensuring an adequate gas exchange without further damaging the lungs. Adjunctive therapy consists mainly of individually adapted "protective" ventilation treatment and the prone position. In severest ARDS, the use of venovenous extracorporeal membrane oxygenation (VV-ECMO) can improve survival if strict criteria for indications and contraindications are followed.

Strokes are common neurological emergencies that require rapid diagnosis to minimize long-term damage. Prehospital detection and triage play a critical role in patient outcomes.

Intravenous thrombolysis (IVT) and endovascular therapy (EVT) are the cornerstones of acute ischemic stroke treatment. While IVT has been an integral part of acute therapy since the mid-1990s, EVT has evolved as one of the most effective treatments in medicine over the past decade. Traditionally, systemic thrombolysis has been performed with alteplase (rtPA). More recently, tenecteplase (TNK) has been shown to be non-inferior to rtPA. TNK has some pharmacological advantages over rtPA and may lead to earlier recanalization, particularly in large vessel occlusions. All recanalization therapies are highly time dependent. To ensure rapid treatment, standard operating procedures (SOPs) should be established and followed in clinical practice. The optimal time window for IVT is 4.5 h after symptom onset and can be extended up to 9 h using specialized imaging techniques. For EVT, studies suggest a time window up to 24 h after symptom onset. In some cases, EVT has been successfully performed beyond this time window. To select patients for EVT, advanced imaging identifying salvageable brain tissue might be necessary. Even in large ischemic stroke, EVT can still improve outcome. Compared to EVT, IVT requires fewer technical and human resources, so more stroke patients can potentially be treated. In contrast, EVT requires highly trained personnel with sophisticated equipment and can, therefore, only be performed in specialized centers. Both procedures should be combined within the 4.5 h time window for patients without contraindications.

In this study, we aimed to evaluate the role of the glucose-to-potassium ratio in predicting in-hospital mortality and prognosis of patients diagnosed with sepsis and septic shock in an emergency department and admitted to an emergency critical intensive care unit (ICU).

Pulmonary arterial embolism (PE) is not well characterized in elderly patients. In addition, unnecessary computed tomography pulmonary angiography (CTPA) examinations are often performed within this patient group, especially if the pretest probability is low.

We report the case of a young patient with severe hypoxic brain injury after cardiopulmonary resuscitation, resulting in brain death/death by neurologic criteria (BD/DNC). Consistent with the patient's expressed wishes, treatment was sustained to facilitate organ donation. However, in the context of a severe post-resuscitation syndrome and physiological disturbances resulting from BD/DNC, refractory circulatory shock ensued. Stabilization was only possible by mechanical circulatory support (MCS). By implementation of MCS for extracorporeal organ support (ECOS), successful organ donation was rendered possible. Further debate is required concerning ethical issues, particularly concerning resource distribution, the timing of ECOS in relation to the diagnosis of BD/DNC and concerning specific consent for the invasive procedure. Until guidelines are presented, we believe that ECOS should be considered in the management of select potential donors in severe shock even before, and certainly after the diagnosis of BD/DNC.

The persistently low number of postmortem organ donations in Germany has repeatedly led to political discussions and most recently to the amendment of the Transplantation Act with the strengthening of the role of the transplantation officer and the introduction of a register to document the will to donate. The background to these decisions was the assumption that a relevant proportion of potential organ donors in hospitals were being overlooked and not reported. However, due to the lack of guidelines as to when a potential organ donor must be reported to the DSO ("Deutsche Stiftung Organspende"), the existing data is only of limited validity.

Early mobilization of critical ill patients in the intensive care unit (ICU) has a positive effect on outcome. Currently, due to concerns of cerebral vasospasm and rebleeding patients with subarachnoid hemorrhage (SAH) have a prolong bedrest for 12-14 days.

Venovenous extracorporeal membrane oxygenation (VV ECMO) is an established support option for patients with very severe respiratory failure and played an important role during the coronavirus disease 2019 (COVID-19) pandemic. Bacteria and fungi can lead to severe infectious complications in critically ill patients. The aim of this study was to describe the microbiological spectrum of bacteria and fungi detected in patients with COVID-19-associated respiratory failure supported with VV ECMO in our center.

In Germany, a substantial reform of emergency care is strictly recommended. Regulation of patient flows into the ambulatory and stationary sectors remains a major issue.In the OPTINOFA project funded by Innovationsfunds, a new triage system was developed for a structured primary evaluation of both urgency and care level of emergency cases. OPTINOFA was evaluated in a cluster-randomized, controlled multicenter trial using a stepped-wedge design in eight emergency departments (ED) from 1 July 2019 to 31 May 2021. Additionally, data from one ED were used for comparison of temporal changes without intervention. The primary study endpoint represented the increase of patient transfers to the ambulatory sector; secondary endpoints included the outcome, process and quality indicators as well as mean emergency care costs.In the study, 46,558 emergency cases were included in the control period and 37,485 emergency cases in the intervention period. Concerning the primary endpoint, a significant increase of transfers to the ambulatory sector were detected in the per-protocol EDs (p < 0.001, odds ratio = 10.59). Waiting times were significantly reduced by an average 20 min in the intervention phase. Furthermore, a stable admission rate was found within 3 days after initial ED presentation. Cost analysis revealed no increase of treatment expenses within 28 days after ED admission.In this project a valid assistant service for structured primary evaluation of urgency and care level was successfully developed for emergency cases and served as a digital triage instrument with interoperable format. Clinical trial results revealed great potential for the OPTINOFA triage system to control patient flows in emergency and acute medicine.

Epileptic seizures, which are often accompanied by a reduction in vigilance, are a common emergency. Every first-time epileptic seizure should be investigated further. Particular attention should be paid to whether it is an acute symptomatic seizure, which is an acute event characterized by a metabolic disorder or acute cerebral damage within a certain period of time, or possibly epilepsy. In terms of differential diagnosis, psychogenic nonepileptic seizures also pose a challenge, as they are often not easy to distinguish from epileptic seizures, but require a different therapeutic approach. Persistent epileptic seizures in the sense of status epilepticus (duration: > 5 min) are also common in the (pre)clinical emergency situation and require immediate initiation of adequate therapy, which consists of rapid and sufficient administration of benzodiazepines. Nasal administration is a quick and simple option here, particularly in the prehospital setting. Furthermore, persistent reductions in vigilance are a not infrequently occurring phenomenon in the (pre)clinical setting, which is, however, based on numerous differential diagnoses. Here, nonconvulsive status epilepticus should be considered as a possible cause and rapid diagnosis using EEG should be sought in order to begin early treatment, which improves patient outcomes.

CAR-T cell (chimeric antigen receptor T) therapy is now part of standard of care treatment of B‑cell lineage malignancies. Although it is an effective treatment, it comes along with adverse side effects and toxicities that may require intensive care therapy. The costs related to critical care therapy in critically ill patients after CAR‑T administration have not been evaluated.
