[Puzzling B symptoms in a 61-year-old patient under treatment for rheumatoid arthritis]. / Rätselhafte B-Symptomatik bei einem 61-Jährigen unter Therapie einer rheumatoiden Arthritis.

A patient with rheumatoid arthritis and immunosuppression developed symptoms of wasting, neuropathy and lung cavitations eventually leading to central nervous system symptoms and fatal multi-organ failure. Disseminated infection with Histoplasma capsulatum proved to be the underlying cause. The primary infection had apparently been acquired 4 years earlier on a holiday to the Caribbean. Rare infectious diseases should be considered in patients under immunosuppression and travel activities to specific endemic areas.

[Pharmacological/pharmaceutical counseling in intensive care medicine]. / Die pharmakologische/pharmazeutische Visite in der Intensivmedizin.

Adequate pharmacotherapy in critically ill patients is challenging for many clinicians. Disease-related pathophysiological changes often lead to complex therapy strategies including many intensive care treatments (e.g. invasive ventilation, renal replacement therapy). These measures often influence drug prescribing and dosing. Therefore, in organ dysfunction such as renal and liver impairment reduced drug elimination has to be considered by adapting drug dosing towards elimination rates. Moreover, as intensive care medicine often includes the use of multiple drugs the risk for drug-drug interactions increases. The current article gives an overview about the complexity of individual pharmacotherapy in intensive care units whilst providing information for its clinical implementation.

[Core curriculum Medical intensive care medicine of the German Society of Medical Intensive Care and Emergency Medicine (DGIIN)]. / Curriculum Internistische Intensivmedizin.

Medical intensive care medicine treats patients with severe, potentially life-threatening diseases covering the complete spectrum of internal medicine. The qualification in medical intensive care medicine requires a broad spectrum of knowledge and skills in medical intensive care medicine, but also in the general field of internal medicine. Both sides of the coin must be taken into account, the treatment with life-sustaining strategies of the acute illness of the patient and also the treatment of patient's underlying chronic diseases. The indispensable foundation of medical intensive care medicine as described in this curriculum includes basic knowledge and skills (level of competence I-III) as well as of behavior and attitudes. This curriculum is primarily dedicated to the internist in advanced training in medical intensive care medicine. However, this curriculum also intends to reach trainers in intensive care medicine and also the German physician chambers with their examiners, showing them which knowledge, skills as well as behavior and attitudes should be taught to trainees according to the education criteria of the German Society of Medical Intensive Care and Emergency Medicine (DGIIN).

[S2k Guideline - Recommendations for Inpatient Therapy of Patients with COVID-19]. / S2k-Leitlinie ­ Empfehlungen zur stationären Therapie von Patienten mit COVID-19.

Since December 2019, the novel coronavirus SARS-CoV-2 (Severe Acute Respiratory Syndrome - Corona Virus-2) has been spreading rapidly in the sense of a global pandemic. This poses significant challenges for clinicians and hospitals and is placing unprecedented strain on the healthcare systems of many countries. The majority of patients with Coronavirus Disease 2019 (COVID-19) present with only mild symptoms such as cough and fever. However, about 6 % require hospitalization. Early clarification of whether inpatient and, if necessary, intensive care treatment is medically appropriate and desired by the patient is of particular importance in the pandemic. Acute hypoxemic respiratory insufficiency with dyspnea and high respiratory rate (> 30/min) usually leads to admission to the intensive care unit. Often, bilateral pulmonary infiltrates/consolidations or even pulmonary emboli are already found on imaging. As the disease progresses, some of these patients develop acute respiratory distress syndrome (ARDS). Mortality reduction of available drug therapy in severe COVID-19 disease has only been demonstrated for dexamethasone in randomized controlled trials. The main goal of supportive therapy is to ensure adequate oxygenation. In this regard, invasive ventilation and repeated prone positioning are important elements in the treatment of severely hypoxemic COVID-19 patients. Strict adherence to basic hygiene, including hand hygiene, and the correct wearing of adequate personal protective equipment are essential when handling patients. Medically necessary actions on patients that could result in aerosol formation should be performed with extreme care and preparation.

Recommendations for treatment of critically ill patients with COVID-19 : Version 3 S1 guideline.

Since December 2019 a novel coronavirus (severe acute respiratory syndrome coronavirus 2, SARS-CoV-2) has rapidly spread around the world resulting in an acute respiratory illness pandemic. The immense challenges for clinicians and hospitals as well as the strain on many healthcare systems has been unprecedented.The majority of patients present with mild symptoms of coronavirus disease 2019 (COVID-19); however, 5-8% become critically ill and require intensive care treatment. Acute hypoxemic respiratory failure with severe dyspnea and an increased respiratory rate (>30/min) usually leads to intensive care unit (ICU) admission. At this point bilateral pulmonary infiltrates are typically seen. Patients often develop a severe acute respiratory distress syndrome (ARDS).So far, remdesivir and dexamethasone have shown clinical effectiveness in severe COVID-19 in hospitalized patients. The main goal of supportive treatment is to ascertain adequate oxygenation. Invasive mechanical ventilation and repeated prone positioning are key elements in treating severely hypoxemic COVID-19 patients.Strict adherence to basic infection control measures (including hand hygiene) and correct use of personal protection equipment (PPE) are essential in the care of patients. Procedures that lead to formation of aerosols should be carried out with utmost precaution and preparation.

[Intensive care back up for infectious disease disasters]. / Intensivmedizinisches Back-up bei infektiologischen Katastrophen.

BACKGROUND: Outbreaks of infectious diseases pose particular challenges for hospitals and intensive care units. OBJECTIVES: Typical infectiological scenarios and their significance for modern intensive care medicine are presented. MATERIALS AND METHODS: Selected pathogens/infectious diseases that have significantly strained the resources of intensive care units are described. RESULTS: Intensive medical care is necessary in severe cases of many infectious diseases. In the context of epidemics/pandemics, many critically ill patients have to be admitted within a short time. Examples are the 2009 H1N1 influenza pandemic, the 2011 enterohemorrhagic Escherichia coli (EHEC) outbreak in northern Germany, the 2014/2015 Ebola fever outbreak and the 2020 coronavirus disease 19 (COVID-19) pandemic. Multidisciplinary teams, protocol development, adequate staffing, and training are required to achieve optimal treatment outcomes, including prevention of healthcare worker infections. CONCLUSIONS: Pandemics and epidemics are unique challenges for intensive care unit preparedness planning.

[Position Paper for the State of the Art Application of Respiratory Support in Patients with COVID-19 - German Respiratory Society]. / Positionspapier zur praktischen Umsetzung der apparativen Differenzialtherapie der akuten respiratorischen Insuffizienz bei COVID-19.

Against the background of the pandemic caused by infection with the SARS-CoV-2, the German Society for Pneumology and Respiratory Medicine (DGP e.V.), in cooperation with other associations, has designated a team of experts in order to answer the currently pressing questions about therapy strategies in dealing with COVID-19 patients suffering from acute respiratory insufficiency (ARI).The position paper is based on the current knowledge that is evolving daily. Many of the published and cited studies require further review, also because many of them did not undergo standard review processes.Therefore, this position paper is also subject to a continuous review process and will be further developed in cooperation with the other professional societies.This position paper is structured into the following five topics:1. Pathophysiology of acute respiratory insufficiency in patients without immunity infected with SARS-CoV-22. Temporal course and prognosis of acute respiratory insufficiency during the course of the disease3. Oxygen insufflation, high-flow oxygen, non-invasive ventilation and invasive ventilation with special consideration of infectious aerosol formation4. Non-invasive ventilation in ARI5. Supply continuum for the treatment of ARIKey points have been highlighted as core statements and significant observations. Regarding the pathophysiological aspects of acute respiratory insufficiency (ARI), the pulmonary infection with SARS-CoV-2 COVID-19 runs through three phases: early infection, pulmonary manifestation and severe hyperinflammatory phase.There are differences between advanced COVID-19-induced lung damage and those changes seen in Acute Respiratory Distress Syndromes (ARDS) as defined by the Berlin criteria. In a pathophysiologically plausible - but currently not yet histopathologically substantiated - model, two types (L-type and H-type) are distinguished, which correspond to an early and late phase. This distinction can be taken into consideration in the differential instrumentation in the therapy of ARI.The assessment of the extent of ARI should be carried out by an arterial or capillary blood gas analysis under room air conditions and must include the calculation of the oxygen supply (measured from the variables of oxygen saturation, the Hb value, the corrected values of the Hüfner number and the cardiac output). In principle, aerosols can cause transmission of infectious viral particles. Open systems or leakage systems (so-called vented masks) can prevent the release of respirable particles. Procedures in which the invasive ventilation system must be opened, and endotracheal intubation must be carried out are associated with an increased risk of infection.The protection of personnel with personal protective equipment should have very high priority because fear of contagion must not be a primary reason for intubation. If the specifications for protective equipment (eye protection, FFP2 or FFP-3 mask, gown) are adhered to, inhalation therapy, nasal high-flow (NHF) therapy, CPAP therapy or NIV can be carried out according to the current state of knowledge without increased risk of infection to the staff. A significant proportion of patients with respiratory failure presents with relevant hypoxemia, often also caused by a high inspiratory oxygen fraction (FiO2) including NHF, and this hypoxemia cannot be not completely corrected. In this situation, CPAP/NIV therapy can be administered under use of a mouth and nose mask or a respiratory helmet as therapy escalation, as long as the criteria for endotracheal intubation are not fulfilled.In acute hypoxemic respiratory insufficiency, NIV should be performed in an intensive care unit or in a comparable unit by personnel with appropriate expertise. Under CPAP/NIV, a patient can deteriorate rapidly. For this reason, continuous monitoring with readiness to carry out intubation must be ensured at all times. If CPAP/NIV leads to further progression of ARI, intubation and subsequent invasive ventilation should be carried out without delay if no DNI order is in place.In the case of patients in whom invasive ventilation, after exhausting all guideline-based measures, is not sufficient, extracorporeal membrane oxygenation procedure (ECMO) should be considered to ensure sufficient oxygen supply and to remove CO2.

[Prevalence of cancer patients in German intensive care units]. / Prävalenz von Krebspatienten auf deutschen Intensivstationen.

INTRODUCTION: Cancer is one of the leading causes of death worldwide. Due to increasing comorbidities, age and aggressive chemotherapy, care of cancer patients in intensive care units (ICUs) is more and more necessary. So far, little is known about the care structure of cancer patients in German ICUs. The aim of this work is to collect and evaluate the prevalence and care data of cancer patients on two reference dates. METHODS: German ICUs were invited to participate in a 2-day, prospective, multicenter point prevalence study in ICU cancer patients. Participation in the study was voluntary and the study was not funded. An ethics vote was obtained to conduct the study. The data were anonymously entered into an eCRF (electronic case report form) by the participating centers. Identification of the patients is therefore not possible. RESULTS: About one in four patients on the ICU/IMC ward had hematological-oncological (HO) disease (n = 316/1319, 24%). The proportion depended significantly on the number of beds in each hospital. The most frequent reasons for admission to the ICU/IMC station were postoperative monitoring (n = 83/221, 37.6%), respiratory instability (n = 79/221, 35.7%), circulatory instability (n = 52/221; 23.5%) and the severe infection with sepsis (n = 47/221; 21.3%). In all, 66.5% (n = 147/221) of the patients had a solid tumor and 21.7% (n = 48/221) had hematological cancer, 78.3% (n = 173/221) of the documented cancer patients received "full-code" intensive management, while 42.5% (n = 94/221) of the HO patients were ventilated and 40.7% (n = 90/221) required catecholamines. The median (mean; IQR) SAPS II score was 35 (37.79, IQR = 24-48) and the median (mean, IQR) TISS score was 10 (13.26, IQR = 10-15). Through the analysis and evaluation of the data available in the context of the prevalence study, it was possible for the first time to determine the Germany-wide cross-center prevalence and care situation of hematological cancer patients in intensive care and intermediate care stations. About one in four patients on German ICUs and IMC wards have a major or minor cancer diagnosis (n = 316/1319 = 24%). Care management is complex in this patient population and requires close interdisciplinary collaboration.

[Presumed consent for organ donation? : A survey among members of the German Society of Medical Intensive Care and Emergency Medicine]. / Widerspruchslösung bei der Organspende? : Eine Umfrage bei Mitgliedern der Deutschen Gesellschaft für internistische Intensivmedizin und Notfallmedizin.

BACKGROUND: Since 2010, the number of organ donations has decreased by 30% in Germany; however, stricter organizational structures in clinics and improved payment for hospital services associated with organ removal should increase the current decline in the number of organ donations in Germany. In addition, the Federal Minister of Health proposed introduction of the double presumed consent solution for organ donation. This proposal is currently being discussed very controversially. Against this background, we conducted an online survey of all members of the German Society of Medical Intensive Care and Emergency Medicine (DGIIN) in order to evaluate the attitude towards organ donation. METHOD: The present work is an anonymous online survey among the members of DGIIN, which took place from 10-23 September 2018. In addition to a few demographic queries, the personal opinion on the regulation of organ donation was collected. RESULTS: A total of 1019 (51.9%) of 1964 invited DGIIN members took part at the survey: 79.3% of the participants were male; average age 47.5 ± 11.2 years; 97.7% were physicians, of whom 89.2% were specialists and 62.7% had the additional degree in critical care; 20.6% voted for the current decision-making solution, 43.1% for the presumed consent, 33.1% for the double presumed consent, whereas 3.2% of the respondents were uncertain in their decision. CONCLUSION: A clear majority of the surveyed members of DGIIN support the concept of presumed consent.

[Impact of nursing staff shortage on intensive care medicine capacity in Germany]. / Auswirkungen des Pflegepersonalmangels auf die intensivmedizinische Versorgungskapazität in Deutschland.

BACKGROUND: Compared to other countries, Germany has the highest number of intensive care unit (ICU) beds, but, despite this, a shortage in ICU care is evident. Currently, little comprehensive data on ICU staffing and on subsequent closure of ICU beds are available. The current survey therefore aimed to systematically investigate the closure of ICU beds. METHOD: A survey was performed among authorized professional trainers in ICU medicine. RESULTS: Overall, a shortage of ICU beds following bed closure was evident in 76% of all ICU floors with 22% reporting daily ICU bed closure. In 47%, two ICU beds were not available. Emergency care was unrestricted in only 18%, while restrictions were reportedly frequent or even constant in 30%. The main reasons for ICU bed closure were the unavailability of ICU nurses (44%) and the co-existing unavailability of nurses and physicians (19%). On average, the nurse/patient ratio was 1:2.5 in the morning, 1:2.6 in the afternoon, and 1:3.1 in the night shift. CONCLUSIONS: ICU bed closure regularly occurs in Germany. The underlying main reason has been identified to be the unavailability of ICU nursing staff. This is suggested to directly interfere with emergency care. For this reason, an action plan is urgently needed.

[Airway management in intensive care and emergency medicine : What is new?] / Atemwegssicherung in der Intensiv- und Notfallmedizin : Was gibt es Neues?

In acute respiratory insufficiency, oxygenation and/or ventilation support by mechanical ventilation is an integral part of intensive care and emergency medicine. Effective airway management is essential to prevent hypoxic complications during the securing of the airway. This includes for example the recognition of difficult airways and adequate pre-oxygenation. While the laryngeal tube can be used in the context of cardiopulmonary resuscitation in emergency medicine, endotracheal intubation is standard in intensive care medicine. In addition to direct laryngoscopy (DL), indirect laryngoscopy using video laryngoscopy (VL) is also available. Compared to DL, advantages in intubation success, anticipated difficult airways, and a reduction of mucosa damage have been shown for VL, whereas the advantage for intubation success could only be demonstrated for experienced physicians who should always be present due to the potential complications of intubation. With regard to mortality and incidence of hypoxia, no difference between DL and VL could be shown. According to current data, the VL should not be used preclinically. A tracheostomy is often performed for long-term ventilation. It is still unclear which patients benefit from an early tracheostomy. Usually the bed-side percutaneous dilatation tracheostomy technique is used, which is often performed under bronchoscopic guidance.
