The novel CaMKII inhibitor GS-680 reduces diastolic SR Ca leak and prevents CaMKII-dependent pro-arrhythmic activity.

RATIONALE: Ca/calmodulin-dependent protein kinase II (CaMKII) was shown to increase diastolic sarcoplasmic reticulum (SR) Ca leak, which can result in delayed afterdepolarizations and triggered arrhythmias. Since increased CaMKII expression and activity has been mechanistically linked to arrhythmias in human heart failure (HF) and atrial fibrillation (AF), specific strategies aimed at CaMKII inhibition may have therapeutic potential. OBJECTIVE: We tested the antiarrhythmic and inotropic effects of a novel selective and ATP-competitive CaMKII inhibitor (GS-680). METHODS AND RESULTS: Trabeculae were isolated from right atrial appendage biopsies of patients undergoing cardiac surgery. Premature atrial contractions (PACs) were induced by stimulation with isoproterenol (ISO, 100 nM) at increased [Ca]o (3.5 mM). Interestingly, compared to vehicle, PACs were significantly inhibited by exposure to GS-680 (at 100 and 300 nM). GS-680 also significantly decreased early and delayed afterdepolarizations in isolated human atrial myocytes. Moreover, GS-680 (at 100 or 300 nM) significantly inhibited diastolic SR Ca leak, measured as frequency of spontaneous SR Ca release events (Ca sparks) in isolated human atrial myocytes (Fluo-4 loaded) similar to the well-established peptide CaMKII inhibitor AIP. In accordance, GS-680 significantly reduced CaMKII autophosphorylation (Western blot) but enhanced developed tension after 10 or 30 s pause of electrical stimulation (post-rest behavior). Surprisingly, we found a strong negative inotropic effect of GS-680 in atrial trabeculae at 1 Hz stimulation rate, which was not observed at 4 Hz and abolished by beta-adrenergic stimulation. In contrast, GS-680 did not impair systolic force of isolated ventricular trabeculae from explanted hearts of heart transplant recipients at 1 Hz, blunted the negative force-frequency relationship (1-3 Hz) and significantly increased the Ca transient amplitude. CONCLUSION: The novel ATP-competitive and selective CaMKII inhibitor GS-680 inhibits pro-arrhythmic activity in human atrium and improves contractility in failing human ventricle, which may have therapeutic implications.

[Use of near-infrared spectroscopy for control of limb perfusion during venoarterial ECMO treatment : Application and limitations]. / Verwendung der Nahinfrarotspektroskopie zur Kontrolle der Extremitätenperfusion unter venoarterieller ECMO-Therapie : Einsatz und Limitationen.

Patients undergoing peripheral venoarterial extracorporeal membrane oxygenation have a high risk of lower limb ischemia. In general, regular controls are carried out based on clinical and laboratory parameters in order to quickly detect and treat complications. These controls are challenging due to states of shock, nonpulsatile flow and vasopressor therapy. As additional monitoring the use of near-infrared spectroscopy (NIRS) is described in the literature as being very successful in detecting ischemia. The present article describes the use and possible limitations of NIRS for the diagnostics of peripheral ischemia.

[Anesthesia management in implantation of baroreceptor stimulators]. / Anästhesiologisches Management bei Implantation von Barorezeptorstimulatoren.

Baroreceptor stimulators are novel implantable devices that activate the carotid baroreceptor reflex. This results in a decrease in activity of the sympathetic nervous system and inhibition of the renin-angiotensin-aldosterone system. In patients with drug-resistant hypertension, permanent electrical activation of the baroreceptor reflex results in blood pressure reduction and cardiac remodeling. For correct intraoperative electrode placement at the carotid bifurcation, the baroreceptor reflex needs to be activated several times. Many common anesthetic agents, such as inhalation anesthetics and propofol dampen or inhibit the baroreceptor reflex and complicate or even prevent successful placement. Therefore, a specific anesthesia and pharmacological management is necessary to ensure successful implantation of baroreceptor reflex stimulators.

[Patients with implanted ventricular assist devices : Challenge for emergency medicine]. / Patienten mit implantierten Herzunterstützungssystemen : Herausforderung in der Notfallmedizin.

Due to a huge increase in the implantation of ventricular assist devices (VAD) over the last few years and the enormous technical advances in functional safety, a growing number of patients with VAD are discharged from hospital, who are still considered to be severely ill. This results in an increased probability of these patients interacting with emergency services where personnel are unaware of the presence of a VAD, creating anxiety and uncertainty regarding how to treat these patients. This article presents an overview of the most common problems and pitfalls regarding VADs. It also presents an algorithm for dealing with emergencies involving these patients including the diagnostics, treatment and primary transport.

[Simulation as possible training for palliative emergencies: prospective initial data analysis of participants from two simulation training sessions]. / Simulation als Möglichkeit zum Training palliativer Notfälle : Prospektive erste Datenanalyse von Teilnehmern zweier Simulationstrainings.

BACKGROUND: Palliative emergencies describe an acute situation in patients with a life-limiting illness. At present defined curricula for prehospital emergency physician training for palliative emergencies are limited. Simulation-based training (SBT) for such palliative emergency situations is an exception both nationally and internationally. AIM: This article presents the preparation of recommendations in the training and development of palliative care emergency situations. MATERIAL AND METHODS: A selected literature search was performed using PubMed, EMBASE, Medline and the Cochrane database (1990-2013). Reference lists of included articles were checked by two reviewers. Data of the included articles were extracted, evaluated und summarized. In the second phase the participants of two simulated scenarios of palliative emergencies were asked to complete an anonymous 15-item questionnaire. The results of the literature search and the questionnaire-based investigation were compared and recommendations were formulated based on the results. RESULTS: Altogether 30 eligible national and international articles were included. Overall, training curricula in palliative emergencies are currently being developed nationally and internationally but are not yet widely integrated into emergency medical training and education. In the second part of the investigation, 25 participants (9 male, 16 female, 20 physicians and 5 nurses) were included in 4 multiprofessional emergency medical simulation training sessions. The most important interests of the participants were the problems for training and further education concerning palliative emergencies described in the national and international literature. CONCLUSION: The literature review and the expectations of the participants underlined that the development and characteristics of palliative emergencies will become increasingly more important in outpatient emergency medicine. All participants considered palliative care to be very important concerning the competency for end-of-life decisions in palliative patients. For this reason, special curricula and simulation for dealing with palliative care patients and special treatment decisions in emergency situations seem to be necessary.

[Veno-arterial extracorporeal membrane oxygenation. Indications, limitations and practical implementation]. / Venoarterielle extrakorporale Membranoxygenierung. Indikationen, Limitationen und praktische Anwendung.

Due to the technical advances in pumps, oxygenators and cannulas, veno-arterial extracorporeal membrane oxygenation (va-ECMO) or extracorporeal life support (ECLS) has been widely used in emergency medicine and intensive care medicine for several years. An accepted indication is peri-interventional cardiac failure in cardiac surgery (postcardiotomy low cardiac output syndrome). Furthermore, especially the use of va-ECMO for other indications in critical care medicine, such as in patients with severe sepsis with septic cardiomyopathy or in cardiopulmonary resuscitation has tremendously increased. The basic indications for va-ECMO are therapy refractory cardiac or cardiopulmonary failure. The fundamental purpose of va-ECMO is bridging the function of the lungs and/or the heart. Consequently, this support system does not represent a causal therapy by itself; however, it provides enough time for the affected organ to recover (bridge to recovery) or for the decision for a long-lasting organ substitution by a ventricular assist device or by transplantation (bridge to decision). Although the outcome for bridged patients seems to be favorable, it should not be forgotten that the support system represents an invasive procedure with potentially far-reaching complications. Therefore, the initiation of these systems needs a professional and experienced (interdisciplinary) team, sufficient resources and an individual approach balancing the risks and benefits. This review gives an overview of the indications, complications and contraindications for va-ECMO. It discusses its advantages in organ transplantation and transport of critically ill patients. The reader will learn the differences between peripheral and central cannulation and how to monitor and manage va-ECMO.

Lipid emulsion pretreatment has different effects on mepivacaine and bupivacaine cardiac toxicity in an isolated rat heart model.

BACKGROUND: The use of lipid emulsions to reduce cardiac toxicity of local anaesthetics (LAs) has shown success in experimental studies and some clinical cases, and thus has been implemented in clinical practice. However, lipid treatment is usually given after the occurrence of neurological or cardiovascular symptoms of systemic intoxication. The aim of this study was to determine if pretreatment with lipid emulsion reduces cardiac toxicity produced by bupivacaine or mepivacaine. METHODS: Isolated rat hearts were perfused with or without lipid emulsion (0.25 ml kg(-1) min(-1)) before administration of equipotent doses of bupivacaine (250 µM) or mepivacaine (1000 µM). Haemodynamic parameters and times from start of perfusion LA to a 1 min period of asystole and recovery were determined. RESULTS: Pretreatment with lipid emulsion extended the time until occurrence of asystole and decreased times to recovery in bupivacaine-induced cardiac toxicity but not in mepivacaine-induced cardiac toxicity compared with control. Lipid pretreatment impaired rate-pressure product recovery in mepivacaine-intoxicated hearts. CONCLUSIONS: This study confirms that pretreatment with a lipid emulsion reduces cardiac toxicity of LAs. The efficacy of pretreatment with lipid emulsion was LA-dependent, so pharmacokinetic properties, such as lipophilicity, might influence the effects of lipid emulsion pretreatment.

[Perioperative care of palliative patients by the anesthetist : medical, psychosocial and ethical challenges]. / Perioperative Betreuung von Palliativpatienten durch den Anästhesisten : Medizinische, psychosoziale und ethische Herausforderungen.

Anesthetists will encounter palliative patients in the daily routine as palliative patients undergo operations and interventions as well, depending on the state of the disease. The first challenge for anesthetists will be to recognize the patient as being palliative. In the course of further treatment it will be necessary to address the specific problems of this patient group. Medical problems are optimized symptom control and the patient's pre-existing medication. In the psychosocial domain, good communication skills are expected of anesthetists, especially during the preoperative interview. Ethical conflicts exist with the decision-making process for surgery and the handling of perioperative do-not-resuscitate orders. This article addresses these areas of conflict and the aim is to enable anesthetists to provide the best possible perioperative care to this vulnerable patient group with the goal to maintain quality of life and keep postoperative recovery as short as possible.

[Successful infection control in regional anesthesia procedures: observational survey after introduction of the DGAI hygiene recommendations]. / Erfolgreiche Infektionskontrolle bei Regionalanästhesieverfahren: Verlaufsbeobachtung nach Einführung der DGAI-Hygieneempfehlungen.

BACKGROUND: In the context of regional anesthesia procedures adverse events rarely occur but are predominantly systemic intoxication due to local anesthetics (0.01-0.035 %), nerve injuries (0.01-1.7 %) and infections (0-3.2 %). MATERIALS AND METHODS: In a level 1 trauma centre data from all continuous peripheral nerve blocks (cPNB) were prospectively acquired over a period of 8 years (2002-2009) in an observational study (n = 10,549). The acquisition of data was carried out in an intranet-based data bank which was accessible for 24 h on every anesthesia workstation. The collected data included type of block, catheter duration and accompanying complications. This study was carried out with special respect to infectious complications (inflammation and infection). RESULTS: In the years 2002-2004 unexpectedly high rates of infectious complications were observed in 3,491 cPNBs with 146 inflammations (4.2 %) and 112 infections (3.2 %). Based on these alarming findings the existing hygiene regime was revised. The innovations were incorporated into the "Hygiene recommendations for the initiation and continued care of regional anaesthetic procedures" of the German Society for Anaesthesiology and Intensive Care Medicine (Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin, DGAI). A major change was the extension of skin disinfection to a spray-and-scrub combined procedure lasting 10 min. The introduction of this care bundle was carried out in 2005. Among 7,053 cPNBs that were conducted between 2005 and 2009 inflammation occurred in only 183 procedures (2.6 %) and infection in 61 procedures (0.9 %). This reduction was highly significant in both categories (p < 0.001). The risk factors catheter duration and catheter localization statistically remained unchanged during the observational period CONCLUSION: Using a real-time computer-based tool for data capture makes a veritable detection of adverse events possible. Such a tool also has the power to monitor the effects of changes in clinical procedures (SOP). In this case it was possible to verify the successful introduction of an extended hygiene care bundle. The new regime significantly decreased the rate of infections in cPNB.

[Preoperative risk evaluation from the perspective of anaesthesiology]. / Präoperative Risikoevaluation aus anästhesiologischer Sicht.

Medical and technical progress together with demographic changes has led to a more complex perioperative care for patients. Accordingly, an optimal preoperative assessment in particular an adequate risk evaluation is more important than ever. A recently published joint recommendation of the German Society of Anaesthesiology and Intensive Care Medicine, the German Society of Surgery and the German Society of Internal Medicine aims to reduce considerable uncertainties in the preoperative risk evaluation especially with regard to"technical tests" by providing transparent and comprehensive arrangements. Consequently, routine screening will be abandoned in favour of targeted patient and operation-oriented individual risk assessment. This approach will change the preoperative risk evaluation in a scientific, organisational and economic way. The following article on preoperative risk evaluation is based on the valuable and helpful recommendation and aims to provide additional important aspects from the perspective of anaesthesiologists.

[Intensive care unit-acquired weakness in the critically ill : critical illness polyneuropathy and critical illness myopathy]. / Erworbene Muskelschwäche beim kritisch Kranken : Critical-Illness-Polyneuropathie und Critical-Illness-Myopathie.

Intensive care unit-acquired weakness (ICUAW) is a severe complication in critically ill patients which has been increasingly recognized over the last two decades. By definition ICUAW is caused by distinct neuromuscular disorders, namely critical illness polyneuropathy (CIP) and critical illness myopathy (CIM). Both CIP and CIM can affect limb and respiratory muscles and thus complicate weaning from a ventilator, increase the length of stay in the intensive care unit and delay mobilization and physical rehabilitation. It is controversially discussed whether CIP and CIM are distinct entities or whether they just represent different organ manifestations with common pathomechanisms. These basic pathomechanisms, however, are complex and still not completely understood but metabolic, inflammatory and bioenergetic alterations seem to play a crucial role. In this respect several risk factors have recently been revealed: in addition to the administration of glucocorticoids and non-depolarizing muscle relaxants, sepsis and multi-organ failure per se as well as elevated levels of blood glucose and muscular immobilization have been shown to have a profound impact on the occurrence of CIP and CIM. For the diagnosis, careful physical and neurological examinations, electrophysiological testing and in rare cases nerve and muscle biopsies are recommended. Nevertheless, it appears to be difficult to clearly distinguish between CIM and CIP in a clinical setting. At present no specific therapy for these neuromuscular disorders has been established but recent data suggest that in addition to avoidance of risk factors early active mobilization of critically ill patients may be beneficial.

[Anesthesiology and palliative medicine. Structured results of a prospective questionnaire-based survey in German hospitals]. / Anästhesiologie und Palliativmedizin. Strukturelle Ergebnisse einer prospektiven Umfrage in deutschen Kliniken.

BACKGROUND: Anesthesiology departments were often integrated into the primary formation of palliative activities in Germany. The aim of this study was to present the current integration of anesthesiology departments into palliative care activities in Germany. METHODS: The objective was to determine current activities of anesthesiology departments in in-hospital palliative care. A quantitative study was carried out based on a self-administered structured questionnaire used during telephone interviews. RESULTS: A total of 168 out of 244 hospitals consented to participate in the study and the response rate was 69%. In-hospital palliative care activities were reported for most of the surveyed hospitals. Only two hospitals in the maximum level of care reported no activities. Participation in these activities by anesthesiology departments was described in up to 92%. Historically, most activities are due to the commitment of individuals, whereas the development of palliative care of cancer pain services and hospital support teams took place in the university hospitals by 2005. CONCLUSIONS: Until 2005 many university palliative care activities had their origins in cancer pain services. These were often integrated into anesthesiology departments. Currently, anesthesiology departments work as an integrative part of palliative medicine. However, it appears from the present results that there is a domination of internal medicine (especially hematology and oncology) in palliative activities in German hospitals. This allows the focus of palliative activities to be formed by subjective specialist interests. Such a state seems to be reduced by the integration of anesthesiology departments because of their neutrality with respect to faculty-specific medical interests. Advantages or disadvantages of these circumstances are not considered by the present investigation.

Contrast-enhanced ultrasound improves real-time imaging of ablation region during radiofrequency ablation: preliminary results.

PURPOSE: To assess the added value of depicting tumour microvascularisation, using dynamic contrast enhanced (CEUS), during radiofrequency ablation, as a means of achieving a complete ablation (CA) of malignant liver lesions. MATERIAL AND METHODS: 18 consecutive patients (2 female, 16 male, age range 52-79 years, mean 64.1 ± 9.9 years) with 22 histologically confirmed hepatic malignancies (HCC: n = 10, liver metastases: n = 12) underwent RFA. Before RFA treatment, conventional US, CEUS and contrast enhanced CT (ceCT) of the liver were performed. During the CT-guided RFA procedure, CEUS was performed to asses the ablation defect. In case of partial ablation a subsequent ablation was performed with a corrected electrode position and evaluated again using CEUS. This procedure was repeated until a CA was achieved. The number of ablations per patient was recorded. Secondary efficacy parameters assessed were lesion detectability in the different imaging modalities and contrast phases. RESULTS: Overall intraprocedural CEUS led to a change in therapeutic management in 59% of cases, resulting in 17 additional ablation cycles. Lesion detectability during CT Fluoroscopy was the sole statistical significant predictor of incomplete ablations (p = 0.008). The mean number of ablations for detectable lesions was 1.27 vs. 2.27 ablations for not detectable lesions (p = 0.002). The combined CT and CEUS RFA procedure led to a CA for all treated lesions in follow up 3 month post intervention. CONCLUSION: CEUS does allow a reliable and immediate assessment of therapeutic efficacy of percutaneous RFA procedures of malignant liver lesions, through the continuous dynamic evaluation of tumour microcirculation.

[Enteral feeding tubes for critically ill patients]. / Ernährungssonden bei kritisch kranken Patienten.

The use of enteral feeding tubes is an important part of early enteral feeding in intensive care medicine. In other faculties with non-critically ill patients, such as (oncologic) surgery, neurology, paediatrics or even in palliative care medicine feeding tubes are used under various circumstances as a temporary or definite solution. The advantage of enteral feeding tubes is the almost physiologic administration of nutrition, liquids and medication. Enteral nutrition is thought to be associated with a reduced infection rate, increased mucosal function, improved immunologic function, reduced length of hospital stay and reduced costs. However, the insertion and use of feeding tubes is potentially dangerous and may be associated with life-threatening complications (bleeding, perforation, peritonitis, etc.). Therefore, the following article will give a summary of the different types of enteral feeding tubes and their range of application. Additionally, a critical look on indication and contraindication is given as well as how to insert an enteral feeding tube.

[Palliative care and end-of-life patients in emergency situations. Recommendations on optimization of out-patient care]. / Palliativpatienten und Patienten am Lebensende in Notfallsituationen. Empfehlungen zur ambulanten Versorgungsoptimierung.

BACKGROUND: At the end of life acute exacerbations of medical symptoms (e.g. dyspnea) in palliative care patients often result in emergency medical services being alerted. The goals of this study were to discuss cooperation between emergency medical and palliative care structures to optimize the quality of care in emergencies involving palliative care patients. METHODS: For data collection an open discussion of the main topics by experts in palliative and emergency medical care was employed. Main outcome measures and recommendations included responses regarding current practices related to expert opinions and international literature sources. RESULTS: As the essential points of consensus the following recommendations for optimization of care were named: (1) integration of palliative care in the emergency medicine curricula for pre-hospital emergency physicians and paramedics, (2) development of outpatient palliative care, (3) integration of palliative care teams into emergency medical structures, (4) cooperation between palliative and emergency medical care, (5) integration of crisis intervention into outpatient palliative emergency medical care, (6) provision of emergency plans and emergency medical boxes, (7) provision of palliative crisis cards and do not attempt resuscitation (DNAR) orders, (8) psychosocial aspects concerning palliative emergencies and (9) definition of palliative patients and their special situation by the physician responsible for prior treatment. CONCLUSIONS: Prehospital emergency physicians are confronted with emergencies in palliative care patients every day. In the treatment of these emergencies there are potentially serious conflicts due to the different therapeutic concepts of palliative medical care and emergency medical services. This study demonstrates that there is a need for regulated criteria for the therapy of palliative patients and patients at the end of life in emergency situations. Overall, more clinical investigations concerning end-of-life care and unresponsive palliative care patients in emergency medical situations are necessary.

[Cancer pain therapy in palliative care patients: knowledge of prehospital emergency physicians in training. Prospective questionnaire-based investigation]. / Kenntnisse angehender Notfallmediziner über die Tumorschmerztherapie bei Palliativpatienten. Prospektive fragebogenbasierte Untersuchung.

BACKGROUND: Cancer diseases are often associated with acute and chronic pain. Therefore, cancer pain is a symptom frequently reported by palliative care patients with cancer diseases. Prehospital emergency physicians may be confronted with exacerbation of pain in cancer patients. The aim of this study was to evaluate the knowledge of prehospital emergency physicians in training concerning cancer pain therapy. METHODS: A total of 471 prehospital emergency physicians received a questionnaire (period of time: 2007-2009). The questionnaire was prepared for the study ("mixed methods design"). Twenty-four questions concerning cancer pain therapy (response options: scaling, open) were designed. The evaluation was done descriptively according to professional experience, field name and experience in treating patients with cancer as well. RESULTS: A total of 469 participants completed the questionnaire (response rate 99%). On average, 10.8 (SD +5.7, range 2-24) questions were answered correctly. Resident physicians answered statistically significantly more questions correctly than consultants (p=0.02). Only physicians working in internal medicine achieved statistically significantly better results than other disciplines (e.g., surgery; p=0.01). Physicians with professional experience of less than 5 years answered statistically significantly more questions correctly (p=0.004). CONCLUSIONS: The results of this study verify that emergency physicians in training have insufficient knowledge of pain therapy and end-of-life decisions. The data of this investigation suggest that more attention should be paid to education on pain therapy and end-of-life care in medical curricula. Prehospital emergency physicians may thus be better prepared to provide quality care for palliative patients.

[Out-patient and in-hospital palliative care in Germany : Comparison with emergency medical care infrastructure]. / Ambulante und stationäre palliativmedizinische Patientenversorgung in Deutschland : Vergleich zur notfallmedizinischen Infrastruktur.

BACKGROUND: In Germany, specialized out-patient palliative care systems (SPCS) are still structurally and organizationally under construction. Palliative care patients need an easy access to a qualified SPCS. The purpose of the present investigation was to show the nationwide distribution of all SPCS teams in comparison to the distribution of emergency medical systems. Possibilities for an effective structure of palliative medical care systems will be discussed in order to optimize patient care.. METHODS: All SPCS teams in Germany (according to the Guide to hospices and palliative medicine of the German Association for Palliative Care 2008/2009) were documented. A cartographic representation of the structural distribution of palliative care systems was made taking a catchment area diameter of 50 km for each SPCS team and an accessibility diameter of 20 km for every palliative ward into account. These data were compared with the nationwide distribution of emergency institutions. RESULTS: In Germany 25 SPCS teams and 198 palliative wards could be identified. In contrast there are 1,109 emergency physician locations (1,051 ground based, 58 air based). The nationwide distribution of the existing SPCS teams does not at present give exhaustive coverage in comparison to emergency medical structures. No structure which might potentially result in an exhaustive implementation of SPCS teams and palliative stations is recognizable in the analysis or distribution. CONCLUSIONS: The coverage of SPCS and in-hospital palliative care is still a theoretical construct in many regions of Germany. The number of existing SPCS teams and in-patient palliative institutions is insufficient to guarantee an exhaustive coverage of patient care as in emergency medical services. In order to achieve a higher quality of results the quality of the structure and processes must first be ensured. The distribution of palliative care should be centrally coordinated along the same lines as the emergency institutions in order to achieve a need-oriented exhaustive coverage. A surplus of care in some regions at the expense of an undersupply in other regions must be avoided. In the next step a further development and adaption of existing structures to the requirements would be a logical approach.

[Emergency medical treatment of palliative care patients at the end of life: regulatory emergency medical care framework--a case control investigation of medical intervention and advance directives]. / Notfallmedizinische Betreuung von Palliativpatienten am Lebensende : Juristische Beurteilung notfallmedizinischer Handlungsweisen - retrospektive Fallbetrachtung zur medizinischen Indikation und zum Patientenwillen.

BACKGROUND: The treatment of out-of-hospital palliative emergency care situations during cardiac arrest is a special situation. The prehospital emergency physician (EP) and the paramedic must be informed about the medical, legal, and ethical specifics of these situations, but this knowledge is not integrated within emergency medical curricula at all. We present a case study to discuss such legal and ethical specifics. METHODS: We retrospectively analysed six emergency cases with palliative care patients in the final stages of their illnesses. On the basis of these case studies, we present six different emergency cases with different regulatory frameworks for each EP and paramedic. In accordance with the Declaration of Helsinki, data were collected pseudonymously. RESULTS: The six case studies show therapeutic concepts concerning the emergency medical care of palliative care patients during cardiac arrest. The differences are apparent in the treatment given by EPs and by paramedics (such as whether to start or stop resuscitation). EPs and paramedics differ in their therapeutic approach to these specific situations (e.g. paramedics more often start resuscitation during cardiac arrest even though patients would refuse this according to their advance directives). These differences may be important for the patient and his or her caregivers. CONCLUSIONS: Every EP and paramedic may be involved in the care of palliative care patients who are at the end of their lives. EPs and paramedics do not always adapt their treatment to the will or supposed will of the patient (especially in accordance with the new German law concerning advance directives). The reasons for this usually concern legal uncertainties. Therefore, EPs and paramedics should know that different legal meanings could be important in emergency medical care therapy of palliative care patients. A written "do not resuscitate" order as an advance directive must be evaluated as a desired therapeutic limitation.
