Abstract
BACKGROUND In critical illnesses low socioeconomic status (SES) is associated with higher morbidity and mortality. In addition to the SES, further factors at an individual level (e.g., sex, health insurance status and place of residence) may influence the severity of illness and medical treatment. We investigated these additional parameters in a secondary analysis of the ECSSTASI data. METHODS Within the framework of the ECSSTASI study, 996 patients were recruited from a surgical intensive care unit. We examined the influence of sex, insurance status and place of residence on health-related behavior, disease severity, duration of intensive care and ventilation (28 ventilator-free days score, 28-VFDS) and social support by the next of kin. Multivariate-adjusted logistic regression analyses were carried out and odds ratios (OR) are presented with corresponding 95% confidence intervals. RESULTS Among patients admitted to the intensive care unit, the disease severity (SOFA score >5) was significantly lower in women than in men (OR 0.62 [0.45-0.87]). Increasing size of the patient's town of residence was associated with a significantly shorter duration of treatment on the intensive care unit (OR 0.54 [0.32-0.91]). An increasing number of persons in the household was associated with a significantly increased risk of being ventilated longer compared to 1‑person households (p = 0.028). Patients with private insurance (OR 1.87 [1.28-2.70]), patients from households with ≥4 persons (OR 1.92 [1.1-3.33]) and patients without German citizenship (OR 2.56 [1.39-4.55]) were visited significantly more often by next of kin. CONCLUSION In addition to the SES, sociodemographic characteristics of the individual patient are associated with the course of treatment in intensive care medicine. The extent of social support by the next of kin depends on intercultural and individual patient characteristics. An increasing size of the town of residence and private health insurance status positively influence intensive care outcomes. In order to evaluate these data, further epidemiological studies in intensive care medicine are necessary.

Abstract
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.

Abstract
BACKGROUND AND OBJECTIVES Cell salvage plays a key role in blood conservation. To maintain high performance, quality management is recommended. Accordingly, a new-generation autotransfusion device was tested for its performance and compared with its predecessor. Two different calculations of quality parameters were applied. MATERIALS AND METHODS In an experimental study, the continuous autotransfusion devices CATSmart and Continuous Autotransfusion System (C.A.T.S) plus were tested using banked blood adjusted to a haematocrit of 20% and anticoagulated with heparin 5 U/L. Test blood was processed using an emergency programme, a high-quality programme/smart wash programme and a low-volume wash programme. Samples were taken after the production of 200 mL of red blood cells (RBC) and after the final emptying of the separation chamber. In an additional set of tests, blood containing 1·25% fat was processed with both devices to examine fat removal. RESULTS Both devices demonstrated an equally high performance with regards to product hematocrit (Hct); RBC recovery; and elimination rates of protein, heparin and fat. The high fat elimination rate (>99·8%) reported for C.A.T.S plus was confirmed for CATSmart, regardless of the used programme. Samples taken during the ongoing process show a higher haematocrit and RBC recovery rate than samples taken after the final emptying of the separation chamber. Interface sensors were not affected by fat in the blood. CONCLUSIONS The new-generation autotransfusion device CATSmart is not inferior to its predecessor and shows high performance with regards to RBC recovery, plasma and fat elimination in all programme modes. Samples for quality controls should be taken during blood processing.

Abstract
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.

Abstract
PURPOSE To evaluate and compare the needle placement accuracy, patient dose, procedural time, complication rate and ablation success of microwave thermoablation using a novel robotic guidance approach and a manual approach. METHODS We performed a retrospective single-center evaluation of 64 microwave thermoablations of liver tumors in 46 patients (10 female, 36 male, mean age 66 years) between June 2014 and February 2015. Thirty ablations were carried out with manual guidance, while 34 ablations were performed using robotic guidance. A 6-week follow-up (ultrasound, computed tomography and MRI) was performed on all patients. RESULTS The total procedure time and dose-length product were significantly reduced under robotic guidance (18.3 vs. 21.7 min, [Formula: see text]; 2216 vs. 2881 mGy[Formula: see text]cm, [Formula: see text]). The position of the percutaneous needle was more accurate using robotic guidance (needle deviation 1.6 vs. 3.3 mm, [Formula: see text]). There was no significant difference between both groups regarding the complication rate and the ablation success. CONCLUSION Robotic assistance for liver tumor ablation reduces patient dose and allows for fast positioning of the microwave applicator with high accuracy. The complication rate and ablation success of percutaneous microwave thermoablation of malignant liver tumors using either CT fluoroscopy or robotic guidance for needle positioning showed no significant differences in the 6-week follow-up.

Abstract
The perioperative period is supposed to be a vulnerable period for cancer progression. Results of clinical studies indicate that the use of regional anesthesia can influence and improve oncological outcome of cancer patients. Uncontrolled cell proliferation and resistance to apoptotic cell death are important characteristics of solid tumors. The aim of this study was to investigate the effects of the clinically used local anesthetics ropivacaine or bupivacaine and the opioid analgesic sufentanil on cell proliferation, cell cycle distribution and apoptosis of colon (HT 29 and SW 480) and pancreatic (PaTu 8988t and PANC 1) cancer cell lines in vitro. Cell proliferation was measured by Cell Proliferation ELISA BrdU Assay. Apoptosis was analyzed by annexin V staining and cell cycle distribution was detected by flow cytometry. Ropivacaine, bupivacaine and sufentanil did not change apoptosis rate and cell cycle distribution in clinically concentration. Only high concentrations of ropivacaine or bupivacaine revealed antiproliferative potency. Protective effects of epidural anesthesia observed in clinical studies seem not to be based on direct effects of these drugs on cancer cells.

Abstract
BACKGROUND Extracorporeal carbon dioxide removal (ECCO2-R) allows lung protective ventilation using lower tidal volumes (VT) in patients with acute respiratory failure. The dynamics of spontaneous ventilation under ECCO2-R has not been described previously. This retrospective multivariable analysis examines VT patterns and investigates the factors that influence VT, in particular sweep gas flow and blood flow through the artificial membrane. METHODS We assessed VT, respiratory rate (RR), minute ventilation (MV), and levels of pressure support (0-24 cm H2O), sweep gas flow (0-14 L/min) and blood flow through the membrane (0.8-1.8 L/min) in 40 patients from the moment they were allowed to breathe spontaneously. Modest hypercapnia was accepted. RESULTS Patients tolerated moderate hypercapnia well. In a generalized linear model the increase in sweep gas flow (P<0.001), a low PaCO2 (P=0.029), and an increased breathing frequency (P<0.001) were associated with lower VT. Neither blood flow through the membrane (P=0.351) nor the level of pressure support (P=0.595) influenced VT size. CONCLUSION Higher sweep gas flow is associated with low VT in patients on extracorporeal lung assist and augmented spontaneous ventilation. Such a technique can be used for prolonged lung protective ventilation even in the patient's recovery period.

Abstract
The results of preclinical and clinical studies indicate that the perioperative period is a vulnerable period for cancer progression and metastasis. The risk of cancer cell dissemination is enhanced by the combination of surgical manipulation and perioperative immunosuppression. Whether the oncological outcome of cancer patients can be influenced by the choice of anesthetic techniques is still a matter of debate. This review summarizes the molecular characteristics of cancer and interaction of anesthetic and analgesic drugs with cancer cells.

Abstract
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.

Abstract
The care of patients, suffering from acute, chronic, or malignant pain, requires systematic and interprofessional collaboration between all team members to ensure a holistic approach to pain management. In doing so, the different professions are often in a competitive, tense, or dependent relationship resulting from a lack of precise definitions and concepts regarding their responsibilities in the wide field of pain management. Considering pain management as a whole, we can define numerous interfaces concerning competencies and tasks which may open up some new perspectives on concepts of interprofessional education (IPE). Internationally, there have been many attempts to establish concepts of interprofessional education, and it is considered a great challenge to improve continuing medical education. However, interdisciplinary subjects like pain management may benefit from it. Apart from enhancing specialized knowledge, interprofessional education aims to consider the different roles, skills, and responsibilities as well as interprofessional strategies of decision-making. In Germany, only a few efforts have been made with regard to interprofessional pain education. In the following paper, different challenges, tasks, and roles within the field of pain management are discussed in the sense of potential areas of collaboration in the context of interprofessional education. Against this background, the Regensburg model for interprofessional pain management education is described as one national program to enhance the effectiveness of pain management.

Abstract
BACKGROUND The aim of this study was to conduct an audit of a university inpatient pain consultation service and to examine the quality and the implementation of the recommended therapeutic measures. Factors that influenced the implementation should be identified. PATIENTS AND METHODS All inpatients treated by the consultation service in the years 2009 and 2010 were analyzed retrospectively. Demographic patient characteristics as well as quality parameters of the consultation service and pharmacological and non-pharmacological recommendations and their implementation were analyzed. RESULTS In total 1,048 requests for the consultation service were processed of which 39.7% of the requests were for patients with acute pain, 33.8% with chronic and 19.9% with tumor-associated pain. Measures recommended most were medication, physiotherapy and psychological treatment. Recommended medications were actually prescribed in more than 80%, physiotherapy recommended in about 75% and psychological treatment recommended in 47% of the cases. Only a few influencing factors for the implementation of the recommended measures could be identified. CONCLUSION Many different pain states are seen in an inpatient pain consultation service. The recommendations given are implemented in most cases especially concerning the medication.

Abstract
INTRODUCTION An increase in ethical conflicts is being observed in the modern intensive care setting, as more complex therapeutic strategies are available and the treatment of old and very old patients is integrated into the clinical routine due to changes in medical options and social epidemiology. Physicians, nurses and families need ethical support to come to a decision about medical treatment when value conflicts are involved. METHODS The basis of medical ethics is reported followed by a presentation of personal experiences and a reference overview regarding the impact of ethics consultations. RESULTS Common ethical conflicts in the intensive care setting result from the lack of precise knowledge on patient preferences and due the use of modern "high-tech" intensive care medicine the prognosis of recovery and quality of life of (old) patients seems to be difficult to assess. Ethical definitions of treatment perspectives will find an important and increasing place in intensive care competence in the future, although currently there is a lack of theoretical and practical instruction in ethics. The goal of ethics consultations is to help physicians, nurses and family members by a structuration of the problem and by a moderation of discussion and problem resolution including a special ethical workflow. Ethics consultations seem to be useful in resolving conflicts that may inappropriately prolong unwanted treatment. CONCLUSIONS The increase of the incidence of ethical conflicts in the intensive care setting may impact ethics consultations which help the integration of ethical principles into the clinical practice.

Abstract
The necessity of limiting resource in healthcare systems is becoming increasingly more evident. The population has requirements especially in the field of healthcare which are principally unlimited. However, there are only limited financial resources which can be used to satisfy the wishes of the population. For this reason rationing models are being discussed increasingly more often. One example of these models is called age rationing which means that defined services are only offered to patients up to a particular age. The aim of this article is to discuss the model of age rationing in the context of an optimized use of resources in the healthcare system.

Abstract
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.

Abstract
A case of pulmonary edema after the administration of naloxone for laparoscopic splenectomy is reported. Previous reports of naloxone-induced pulmonary edema are listed and reviewed. The clinical course is compared to other forms of non-cardiogenic pulmonary edema. Uncertainty remains about the underlying pathophysiological process and the true impact of naloxone on the development of pulmonary edema.

Abstract
BACKGROUND Palliative care needs a high level of expertise. In particular, there are some potential difficulties in the treatment of patients with the symptom cancer pain (for example lack of education). In Germany, various physicians are involved in cancer pain treatment but in general palliative care patients are treated by a physician who is educated in palliative medicine. In special circumstances prehospital emergency physicians and other physicians are involved in therapy decisions in palliative care patients as well. The authors surveyed different groups of physicians in Germany about their specific knowledge of cancer pain management. MATERIAL AND METHODS A self-designed, standardized questionnaire (50 items) was given to palliative physicians in training (PP). The survey asked prospectively for knowledge on the World Health Organization (WHO) step ladder of cancer pain therapy. The results were retrolectively compared with an earlier investigation with the same background (emergency physicians in training EP). RESULTS There was a 99.5% response rate with a total of 654 respondents (PP 185, EP 469) and 461 (70.5%) of the respondents had knowledge of the WHO step ladder for the treatment of cancer pain [PP 164/185 (88.6%), EP 297/469 (63.3%), PP versus EP p < 0.001)]. The correct numbers of therapeutic levels were known by 361/461 participants [PP 151/164 (92.1%), EP 210/297 (70.7%), p < 0.001].The EPs with a professional experience less than 5 years answered statistically significantly more questions correctly (p = 0.004). Concerning the defined parameters knowledge and professional experience, there was no statistically significant difference in the group of PP. CONCLUSIONS The results of this study verified that the highest knowledge scores were achieved by PPs and overall, the knowledge scores showed an improvement in comparison to previous investigations. In recent years there seems to have been an improvement in education on pain treatment,for example during medical school. Whether this also leads to an improvement of patient care and the relevance of these data for the clinical practice needs to be investigated in further studies.

Abstract
BACKGROUND General out-patient palliative care (GOPC) must be integrated into the care of patients with life-limiting diseases. Aim of the study was to evaluate experiences of general practitioners concerning advance directives and palliative emergency sheets. METHODS A self-provided survey was mailed to all general practitioners in Regensburg (cross-sectional study). Main outcome measures included responses regarding a palliative emergency sheet (PES) and a palliative emergency plan (PEP). The investigation period was four months. The analysis was performed using defined criteria (e. g. professional experience concerning palliative care patients, patients treated in nursing homes, patients with dementia). RESULTS Sixty-nine questionnaires from 259 were analysed (response rate 27 %). 86 % of respondents named practical experience in the care of palliative patients, 46 % named theoretical knowledge in this field. 41 % and 40 % consider creating an advance directive for their practical work as important/very important (p = 0.004 concerning the treatment of more than five palliative care patients per three months). 52 % and 49 % regard a PES or a PEP to be relevant (PES median: 6.5, SD ± 2.7; PEP median: 6.5 SD ± 2.9; inter-group analysis p < 0.05). 94 % of respondents name the general practitioner to be suitable for creating an advance directive. CONCLUSION In Germany, GOPC in end-of-life care is very important. This study shows that advance directives were declared as an important instrument for patients? autonomy. The sense of PES and PEP to ensure patients? autonomy, especially for acute emergency medical palliative care, must be better recognized. However, the increase in acceptance in the GOPC for such instruments must be disclosed. Further studies to investigate this problem are necessary.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
We report the use of out-of-hospital extracorporeal life support (ECLS) in cardiac arrest. We treated a 9-year-old girl with cardiac arrest after warm-water drowning with percutaneous venoarterial extracorporeal membrane oxygenation (ECMO) using a new portable Mini-ECMO system. A beating-heart circulation was reestablished on ECMO, but, unfortunately, our patient did not survive. This case shows that Mini-ECMO support can be used to restore an effective circulation and gas exchange in the out-of-hospital setting.

Abstract
BACKGROUND According to different algorithms of airway management, emergency cricothyrotomy is the final step in managing an otherwise not accessible airway. As an alternative to an open surgical procedure, minimally invasive approaches exist. Quicktrach baby™ is a commercially available set for a minimal invasive cricothyrotomy in infants. The set consists of a plastic cannula over a metal needle for direct placement in the trachea. So far, this device has not been evaluated for its intended use. OBJECTIVES We hypothesize that Quicktrach baby™ allows the establishment of an emergency airway. The aim was to prove that the device is easy to handle and the cricothyrotomy fast to perform. METHODS After approval of the local ethics committee, the study was performed on the cadavers of 10 adult rabbits. Cricothyrotomy was performed with Quicktrach baby™. Successful placement, performance time, and complication rate were documented. Possible ventilation with a breathing bag was evaluated. Data are reported as mean and interquartile range. RESULTS Successful placement of Quicktrach baby™ was possible in all attempts. The placement took 31 [23-43] s. In two cases, a fracture of the cricoid's cartilage was seen. In one animal, damage to the posterior wall mucosa was observed. In all cases, sufficient ventilation was possible. CONCLUSIONS Quicktrach™ baby proved to be a reliable technique. In the animal model, it is easy and fast to perform. Only a few minor complications occurred. Sufficient ventilation was possible in all attempts.

Abstract
BACKGROUND Palliative medical emergencies and end-of-life decisions resulting from the exacerbation of cancer account for approximately 3% of all out-of-hospital emergency applications in Germany. Therefore, prehospital emergency physicians (EP) may be confronted with advance directives and ethical and end-of-life decisions. The purpose of the study was to identify EPs' knowledge about ethical and end-of-life decisions and their legal education and experiences concerning advance directives. METHODS Over a six-month period, we questioned all 150 EPs from three emergency medical services (Braunschweig, Göttingen und Kaiserslautern). An anonymous, self-administered questionnaire with a mixed-methods design was used. The main outcome measures included responses regarding experiences related to advance directives and end-of-life decisions in palliative care patients. For statistical assessment, EPs were divided into three categories: competent, skilled, and unskilled. RESULTS A total of 104 EPs returned the questionnaire (response rate 69%). Eighty-nine percent of the respondents treated patients who had advance directives. The existence of an advance directive influenced the EP's therapy decision in about 77% of their encounters. Eighty-seven percent of the EPs reported the need for defined end-of-life care pathways and/or standard operating procedures. Eighty-two percent desired educational training concerning end-of-life decisions and the validity of advance directives. CONCLUSION The prehospital emergency treatment of palliative care patients can be particularly challenging for any EP. A high percentage of the EPs in our study felt insecure in dealing with advance directives and ethical and end-of-life decisions in palliative care patients. Our results suggest that EPs may need more information and education about palliative medical care, legal issues and ethical and end-of-life decisions to provide adequate patient-oriented palliative care in prehospital emergency situations.

Abstract
Modern anesthesia is handling an increasing number of patients with neurological diseases who require narcosis. Regional anesthesia techniques offer qualities which might be advantageous for this group particularly for childbirth. The number of pregnant women with neurological diseases has increased significantly in the recent years due to improved diagnostics and therapy. A more careful approach to regional anesthesia in patients with neurological diseases is necessary as the drugs themselves possess neurotoxic effects and the procedure might worsen the underlying neurological diseases. Additionally, performing regional anesthesia might be more complicated and the resulting blockade might be different from the expected neuronal block. Published data concerning regional anesthesia in this patient group are limited and mainly restricted to case reports. In this review general considerations regarding regional anesthesia, techniques, drugs and methods in these patient groups will be discussed. In the second part the practical approach to regional anesthesia for some of the most important neurological diseases is highlighted.

Abstract
Spinal anaesthesia is contraindicated in patients with elevated intracranial pressure or space-occupying intracranial lesions. Drainage of the lumbar cerebrospinal fluid (CSF) can increase the pressure gradient between the spinal, supratentorial and infratentorial compartments. This can result in rapid herniation of the brain stem or occluding hydrocephalus. We present a case of a female patient with an occult brain tumour who received a spinal anaesthesia for an orthopaedic procedure. The primary course of anaesthesia was uneventful. Several hours after surgery, the patient became increasingly disoriented and agitated. The next day, she was found comatose. A computed tomogram of the head revealed herniation of the brain stem, resulting in an occluding hydrocephalus due to a prior not known infratentorial mass. By acute relieving of the intracranial pressure by external CSF drainage, the mass was removed 2 days later. The further post-operative course was uneventful and the patient was discharged from the hospital without neurological deficit 3 weeks after the primary surgery.

Abstract
Safe and effective cranial analgesia can be achieved by blocking the sensitive nerves of that region. These include the supraorbital nerve, the supratrochlear nerve, the zygomaticotemporal nerve, the auriculotemporal nerve and the greater and lesser occipital nerves which are accessible at typical and most proximal points. Preferably long acting local anesthetics such as ropivacaine 0.75% or levobupivacaine 0.5% are used supplemented with 5 microg/ml epinephrine to reduce systemic resorption and to elongate the duration. Scalp blocks are useful for intraoperative neurologic testing of the patient during awake craniotomy or for supplementation of general anesthesia for other forms of craniotomy. Other applications are minimally invasive and stereotactic neurosurgery including deep brain stimulation, photodynamic therapy of actinic ceratosis, cranial plastic surgery and pain therapy.

Abstract
Massive pulmonary embolism (PE) leads to cardiogenic shock and is associated with mortality rates of up to 75%. We report on a 27-year-old mother in childbirth who developed a massive post-partal PE and cardiac arrest. Despite mechanical resuscitation, return of spontaneous circulation (ROSC) could not be achieved. After systemic thrombolysis, ROSC returned, but cardiopulmonary failure was persisting, complicated by massive bleeding shock. By using a newly developed, hand-held ECMO system, systemic blood flow and oxygenation were restored and emergency medical services for advanced surgical treatment (hysterectomy and pulmonary embolectomy) were possible. The patient recovered completely. We assume that this newly developed hand-held ECMO device enables rapid onset mechanical life support and improves the prognosis of patients in fatal conditions.

Abstract
Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) has become an important tool in the management of patients with peritoneal malignancies. It is a complex surgical procedure with significant fluid loss during debulking leading to relevant pathophysiological alterations and therefore a challenge for anesthesiologists and critical care physicians. This review summarizes perioperative changes in hemodynamics, oxygen supply, coagulation, hematopoetic parameters and fluid status during cytoreductive surgery and HIPEC and how to deal with these pathophysiological alterations.

Palliative care medical emergencies as a consequence of advanced cancer account for approximately 3% of all prehospital emergency cases. Therefore, prehospital emergency physicians (EP) are confronted with 'end of life decisions'. No educational content exists concerning palliative medicine in emergency medicine curricula. Over the course of 6 months, we interviewed 150 EPs about their experiences in 'end of life decisions' using a specific questionnaire. The total response rate was 69% (n = 104). Most of the interviewed EPs (89%, n = 93) had been confronted with palliative care medical emergencies and expressed uncertainties in dealing with these difficult situations, especially in the area of psychosocial care of the patients (50%). The emergency treatment of palliative care patients can become a particular challenge for any EP. A large percentage of interviewed EPs felt uncertain about aspects of social care and in the assessment of decisions at the end of life. Further information and training are necessary to amenable EPs to provide adequate patient-oriented care to palliative care patients and their relatives in emergency situations.

Abstract
BACKGROUND Analysis of critical incidents in anaesthesia practice emphasizes the important role of non-technical skills (NTS) in improving patient safety. Therefore, debriefing with regard to NTS has been added to medical management (MM) simulator training to improve acute crisis competencies of anaesthesiologists. The purpose of this study was to compare the NTS and MM performance of two groups of anaesthesiologists in a simulated anaesthesia crisis after undergoing different types of training. METHODS Forty-two anaesthesiologists were randomly assigned to two different training groups, with each group participating in two simulation training sessions. One group's (NTS+MMG) training included extensive debriefing of NTS (resource management, planning, leadership and communication) and MM, while the other group (MMG) received a simpler debriefing that focused solely on MM. The quality and quantity of NTS and quality of MM performance were rated by reviewing the videotapes of the scenarios. RESULTS NTS+MMG did not prove superior to MMG with regard to behavioural and MM markers. The quality of NTS performances correlated significantly (P<0.01) with the quantity of NTS demonstration, and also correlated significantly with the MM actions (P<0.01) in both groups. CONCLUSION A single session of training including debriefing of NTS and MM did not improve the NTS performances of anaesthesiologists when compared with anaesthesiologists who only received MM training. This might indicate that a more frequent or individual training is needed to improve participants' NTS performance.

Abstract
Optimal perioperative fluid management is still controversial. Besides well known perioperative hypovolaemia, hypervolaemia has an influence on perioperative morbidity and mortality, particularly with regard to the patient's medical history, a reduced cardiac and pulmonal function and the operation itself. The concepts of preoperative, intraoperative and postoperative fluid administration are neither adequately validated, nor sufficiently integrated into a perioperative concept. At the present, moderate fluid administration to improve preoperative and postoperative outcome is safe in minor or medium surgical procedures. High-risk surgical patients benefit from a time-oriented or/and goal-oriented monitored fluid therapy. In the past only little attention has been concentrated on postoperative fluid management, but may be stimulated by the new concepts of fast track surgery.

Abstract
BACKGROUND Prehospital emergency teams will be confronted with the specific needs of resuscitation in palliative patients in whom a return of spontaneous circulation (ROSC) could be found significantly less frequently than in other emergency situations. The present investigation aims to show medical and judicial problems related to cardiopulmonary resuscitation (CPR), external examination of the corpse and death certification. METHODS Over a 12-month period all emergency cases involving physicians in an out-of-hospital resuscitation setting in cancer patients were retrospectively analysed for indications for emergency call, situation on-site and prehospital treatment by emergency physicians, external examination of the corpse and determination of death. RESULTS For the period mentioned 164 (2.7% of the total) emergency calls by cancer patients or their relatives were identified. In the following study 43 patients (26.2%) could be included. In 20 cases (46.5%) the emergency physicians attempted to resuscitate the patient by performing CPR. In the majority of cases (36; 83.7%) death certification and external examination of the corpse were necessary at the scene. CONCLUSIONS Due to a reduced rate of ROSC in palliative patients, death certification and external examination of the corpse are more often necessary than in other emergency situations. Therefore every emergency physician should be familiar with the ethics of resuscitation of patients in palliative care and with external examination of the corpse to do justice to patients and their caregivers.

Abstract
BACKGROUND AND OBJECTIVES In 2005 the European Resuscitation Council (ERC) published a revised version of the guidelines for Advanced Life Support (ALS). One of the aims was to reduce the time without chest compression in the first period of cardiac arrest. We evaluated in a manikin study whether using the single use laryngeal tube (LT-D) instead of single use laryngeal mask (LMA) for emergency airway management could reduce the "No Flow Time" (NFT). The NFT is defined as the time during which no chest compressions take place. METHODS Randomised prospective study with 200 volunteers who performed a standardised simulated cardiac arrest management in a manikin following one-day cardiac arrest training (simulation scenario 430 s). Two supraglottic airway devices were compared (LT-D and LMA). Endpoints were the total "no flow time" during the scenario, and the successful airway management with the used airway device. RESULTS In the present manikin study the use of the LT-D significantly reduced NFT compared with the LMA (104.2 s vs. 124.0 s; p < 0.01). The LT-D was correctly positioned by 98 % of the participants on the first attempt compared to 74 % with the LMA. The LT-D was inserted significantly faster than the LMA (12.4 s vs. 29.1 s, p < 0.01). During the cardiac arrest simulation establishing and performing first ventilation took an average of 40.5 s with the LT-D compared to 47.9 s with LMA. CONCLUSIONS In this manikin study data showed that the LT-D may be a good alternative airway device compared to LMA for providing and maintaining a patent airway during resuscitation.

Abstract
We report on the case of a 79-year-old man undergoing a Whipple operation with postoperative unstable respiratory status. Non-invasive ventilation therapy was started and a nasogastric tube (NGT) was placed to lower the risk of gastric accumulation of air. The NGT was placed following recommended clinical procedures. For further examination of the respiratory status, an X-ray was done, which presented the NGT entering the bronchial tree, following the main bronchus down and a newly occurring pneumothorax in the right lung. The NGT was removed immediately and the pneumothorax was treated by drainage of the pleura. Bronchoscopy showed no evidence of tracheobronchial injury. Antibiotic therapy was started and the patient made a full recovery. This case report should remind medical staff of the potential risk of placing a NGT, and gives advice for proper placement to improve patient safety.

Abstract
Currently more and more patients with cancer will be treated at home, especially at the final stage of their disease. Relatives and nursing services will therefore be confronted with acute emergency situations concerning these patients. The handling of these acute situations may be beyond the relatives' coping capacity. For that reason the pre-hospital emergency system (2.5% of all emergency calls) will be confronted with very specific needs of these patients. Emergency situations of palliative patients at home are more predictable than other circumstances. It is thus possible to achieve a practicable preparation for such emergency situations. An individual "emergency plan" should be created for these cases.. The plan may be processed in an emergency situation. It may then be possible to avoid emergency calls and make it possible for the patient to remain at home. This promotes the patient's quality of life and his/her predominant desire to stay at home after the emergency. An advance directive should be made which records the patient's wishes. Because of the complexity of an advance directive it is essential to indicated the patient's wishes in a short and quickly read form in case an emergency arises. This is one of the reasons for producing a short version like the "Göttingen palliative emergency card". In acute situations it is then possible quickly to make known the patient's wishes The patient may be given the possibility of remaining at home after an emergency situation has been dealt with successfully.

Abstract
There are two optical isomers of the 2-(2-chlorophenyl)-2-(methylamino)-cyclohexanone ketamine: S(+) ketamine and R(-) ketamine. Effects of this drug are mediated by N-methyl-d-aspartate (NMDA), opioid, muscarinic and different voltage-gated receptors. Clinically, the anaesthetic potency of the S(+)-isomer is approximately three to four times that of the R(-)-isomer, which is attributable to the higher affinity of the S(+)-isomer to the phencyclidine binding sites on the NMDA receptors. Ketamine is water- and lipid-soluble, allowing it to be administered conveniently via various routes and providing extensive distribution in the body. Ketamine metabolism is mediated by hepatic microsomal enzymes. It causes bronchodilation and stimulation of the sympathetic nervous system and cardiovascular system. In clinics, ketamine and particularly S(+)-ketamine are used for premedication, sedation, and induction and maintenance of general anaesthesia, which is than termed "dissociative anaesthesia". Ketamine and its S(+)-isomer are ideal anaesthetic agents for trauma victims, patients with hypovolemic and septic shock and patients with pulmonary diseases. Even subanaesthetic doses of this drug have analgesic effects, so ketamine is also recommended for post-operative analgesia and sedation. The combination of ketamine with midazolam or propofol can be extremely useful and safe for sedation and pain relief in intensive care patients, especially during sepsis and cardiovascular instability. In the treatment of chronic pain ketamine is effective as a potent analgesic or substitute together with other potent analgesics, whereby it can be added by different methods. There are some important patient side-effects, however, that limit its use, whereby psycho-mimetic side-effects are most common.

Abstract
Since 1st October 2003 the new German "Approbationsordnung für Arzte" (Medical Licensing Regulations) requires an increasing amount of small group teaching sessions and encourages a multidisciplinary and more practical approach to the related topics. In 2004 the German Society of Anaesthesiology and Intensive Care Medicine has provided almost all anaesthesia faculties of German Universities with equipment for full-scale simulation. This article describes methods for a simulation-based medical education training program. Basic requirements for a successful training program using full scale simulators are the provision of an adequate logistical and material infrastructure, teacher attendance of train-the-trainer courses, implementation in the medical curriculum and an instructor-student ratio of 1:3, equivalent to that for bedside teaching. If these requirements were fulfilled, medical students scored the simulation scenarios "induction of anaesthesia", "acute pulmonary embolism", "acute management of a multiple trauma patient" and "postoperative hypotension" as 1.5, 1.6, 1.5 and 1.5, respectively, on a scale of 1-6. These scores were better than those given for other segments of the curriculum.

Abstract
BACKGROUND Presently and even more in the near future more cancer patients will be treated at home especially in the final stage of their disease. For this reason the prehospital emergency system will be confronted with the specific needs of these patients. Palliative care is not part of the German model of post-graduate training regulations for emergency medicine and palliative care teams (PCT) are only involved in the treatment of cancer patients in emergency situations. METHODS Over a 12-month period we retrospectively analysed all emergency cases that had been categorised as final cancer stage at 2 emergency sites (one air-based, the other ground-based) involving physicians in an out-of-hospital setting. We analysed all cases for indications of emergency call, prehospital treatment and involvement of a PCT in the treatment of symptoms. RESULTS For this period we analysed 2,765 emergency documents and identified more than 2.5% as emergency calls by cancer patients or their relatives (the majority of patients had been in the final stage of the disease). Most emergency calls occurred at times when no general practitioner was on duty and acute dyspnoea (42.7%) was the prominent diagnosis. After emergency treatment 61.8% patients had been admitted to hospital. In most settings a PCT was not involved in the treatment of palliative care patients or their relatives (92.7%). CONCLUSIONS Our data demonstrate that care of cancer patients in the final stage of the disease is relevant in emergency medicine. These patients are in need of help based on principles of palliative care. Under these circumstances cooperation of the medical disciplines (emergency and palliative medicine) concerned seems to be necessary. This may increase the possibility for patients to stay at home for the last days of their life. Because of this we are convinced that basic knowledge of palliative care should be integrated into the German model of post-graduate training regulations for emergency care. Combining parts of the curricula (palliative and emergency medicine) it would be possible for emergency physicians to guide their treatment by the ideas and strategies of palliative care. But we are also convinced that the system of PCT should increase and become more involved in prehospital care in emergency cases of palliative care patients.

Abstract
A case is presented of spontaneous return of circulation after cardiac arrest in a patient with a pacemaker without intraoperative resuscitation. In the literature this kind of situation is called the Lazarus phenomenon. Cardiac arrest of the patient occurred during surgery and because of the poor prognosis no cardiopulmonary resuscitation was initiated. After 6 min of apnoea and cessation of circulation, the circulation restarted spontaneously and surgery was continued. Afterwards the patient was transferred to the intensive care unit but died 2 days later without regaining consciousness. The pathophysiological mechanisms for the Lazarus phenomenon are poorly understood but several mechanisms and multifactorial events are discussed in the literature.

Abstract
BACKGROUND In medicine, the use of standard operating procedures (SOPs) is often evaluated using questionnaires (QUES). However, QUES can have limitations with regard to method, thus leading to errors. Simulation (SIM) offers another opportunity for evaluation. We hypothesized that medical errors in the evaluation of SOPs using QUES could be detected by SIM, and that SIM is better qualified to demonstrate applied medicine. METHODS We investigated the use of SOPs in anaesthesia, rapid sequence induction (RSI), by means of a QUES (n=42) or SIM (n=42) among 84 anaesthesiologists. Seven measures for preventing aspiration during induction of anaesthesia were examined and evaluated according to a predetermined points system. RESULTS The average number of times that precautionary measures to prevent aspiration were mentioned in the QUES [4.8 (0.9)] or performed during SIM [5.0 (1.1)] did not differ between the two groups. Pre-oxygenation was the most frequently described or performed measure (95% vs 93%). However, other measures, such as avoidance of positive pressure ventilation (45% vs 85%), differed significantly between the two groups. CONCLUSIONS QUES and SIM are powerful instruments for evaluating the implementation of SOPs such as RSI. SIM demonstrates automated behaviours and thus more clearly represents behaviours used in clinical practice than is possible to demonstrate using QUES. Using a combination of these two instruments, method errors resulting from the individual instruments can be reduced.
