The multiprofessionality in the medical supervision of a birth is also fundamentally well-represented in the compilation of the S3 guidelines by the participating actors and specialist societies. Important from an anesthesiological perspective is the fact that neuraxial procedures still represent the gold standard in obstetric analgesia. With remifentanil PCA an alternative option is available that enables a reliable analgesia to be accomplished, e.g. when there are contraindications to performing neuraxial methods, if this is appropriate under the prevailing circumstances (1:1 support and appropriate monitoring). During an uncomplicated birth the strict fasting rules are relaxed. Overall, the guidelines underline the importance of self-determination and self-control for the expectant mother and give the highest priority to the safety and well-being of mother and child; however, this presupposes that the expectant mother is sufficiently informed about the value of neuraxial analgesia. For this it appears to be of importance to initiate information proposals, which go beyond the usual information sessions for parents that are often organized exclusively by midwives.

The field of activities of the TxB includes not only the identification of donors, the diagnosis of irreversible loss of brain function, donor evaluation and organ protection but also the support of the complete organ donation process. The TxB is responsible for the establishment of in-house hospital standards as well as the organization of advanced and continuing education and is the contact person for all aspects of organ donation. Furthermore, the TxB acts as a link between the coordination center (German Organ Procurement Organization) and the allocation organisation (Eurotransplant). The activities are subject to the Transplantation Act and its implementation statutes; however, the TxB also needs corresponding knowledge of the various guidelines on organ donation and transplantation. Finally, the TxB is also responsible for the quality assurance of the organ donation process.

Disparities in the objectives of the different team members under economic pressure to perform, are sources of potential conflict in the daily work routine. This may have a negative impact on patient safety and commercial efficiency of hospital management. OBJECTIVE: The aim of this summary is to sensitize the reader to the complex of problems in daily life in the OR and to increase awareness of possible approaches to solve the difficulties in an OR. Problem solutions might be approached by improvement of communication and team building. METHODS: Narrative review of current literature and expert recommendations by a literature search in PubMed and Medline; keywords included teamwork, communication, operating room, team building. RESULTS AND CONCLUSION: Communication and teamwork in the OR are of immense importance for patient safety and the economic development of a hospital. Improvements in communication structure, among other things due to the implementation of a team time out and moderation from outside (OR manager) offer solutions to avoid conflicts in everyday clinical practice.

Among the crew members killed was the ship's doctor Dr. med. Heinz Ruppert, a specialist in anesthesiology, gynecology and obstetrics from the University Women's Hospital of the Charité in East Berlin. Since he was also a specialist in anaesthesiology he was primarily responsible for the anaesthesiological care of patients at the University Women's Hospital at the Charité. As an avid supporter of neuraxial conduction anaesthesia techniques, he primarily worked on this topic scientifically and tried to establish peridural anaesthesia in obstetrics. In 1954 he was able to habilitate at the Charité with a thesis on this subject and was appointed as lecturer. His scientific oeuvre has so far not been appreciated, a reason to remember this forgotten German protagonist of gynecological obstetric anaesthesia.

Currently little is known of the frequency of the use of tourniquets in the prehospital setting in Germany. This study evaluated how often a tourniquet is used in a civilian German Helicopter Emergency Medical Service (HEMS). METHOD: After the approval of the scientific working group of the DRF Luftrettung HEMS, the electronic database (HEMSDER) of the DRF Luftrettung HEMS was analyzed for the period 2015-2020 under the abovementioned question. All patients with a tourniquet application were included in the study and a comparison was made with the total trauma cohort and a subgroup analysis between patients who additionally required airway management and patients without additional airway management in the cohort of tourniquet patients. The analysis was mainly descriptive. Parametric test (t-tests and χ-tests) were used for group comparison. RESULTS: During the study period 67,321 trauma patients were treated and in 866 (1.3% of all trauma patients) a tourniquet was used. The mean age of these patients was 45.9 years (±19.5 years), 710 (84%) were male, 439 (51%) suffered a monotrauma, 296 (34%) suffered multiple trauma, 339 (38%) required a prehospital airway management and 321 (37%) of these were intubated. Significant differences between patients with tourniquet application and the rest of the trauma cohort were detected in general data (monotrauma, polytrauma and high-speed trauma, massive bleeding), vital signs at the scene of the accident (GCS, HF, SO) and necessary interventions, such as pressure bandages and use of hemostyptics, tranexamic acid, analgesia, the frequency of intubation and colloidal volume replacement. Due to limitations of the data set we could not obtain information regarding the limb used for the tourniquet, whether a conversion of the tourniquet was carried out and if the tourniquet was used according to the current German trauma guidelines. CONCLUSION: With a frequency of 1.3% the need for a prehospital tourniquet application is low in civilian trauma patients. Monotrauma with isolated extremity injuries represent about half of the patients treated with tourniquets. The other half is represented by multiple injuries or multiple trauma patients who require significantly more invasive measures, such as airway management and more complex on-scene interventions are needed. The available data do not allow any conclusions to be drawn about the location and the quality of the tourniquet application. Future documentation systems should incorporate data on the use of tourniquets, such as the location of use, indications (tactical use/massive bleeding), bleeding control achieved (yes/no) or second tourniquet necessary, conversion (yes/no) and any obvious complications.

The patient history revealed that there had been a previous confirmed contact with a COVID-19 positive patient. The patient developed the complete set of symptoms of COVID-19 pneumonia with extensive intensive care treatment. After about 2 weeks of treatment, weaning had to be stopped due to the deterioration of the severe septic condition of the patient and he showed microbiological evidence of a superinfection with Cryptococcus neoformans and later Leclercia adecarboxylata. The patient was treated successfully and survived the disease.

In recent years an increasing number of monitors were approved, which were developed for the detection of intraoperative nociception and therefore should enable a better control of opioid titration. The nociception monitoring devices use either continuous hemodynamic, galvanic or thermal biosignals reflecting the balance between parasympathetic and sympathetic activity, measure the pupil dilatation reflex or the nociceptive flexor reflex as a reflexive response to application of standardized nociceptive stimulation. This review article presents the currently available nociception monitors. Most of these monitoring devices detect nociceptive stimulations with higher sensitivity and specificity than changes in heart rate, blood pressure or sedation depth monitoring devices. There are only few studies on the effect of opioid titration guided by nociception monitoring and the possible postoperative benefits of these devices. All nociception monitoring techniques are subject to specific limitations either due to perioperative confounders (e.g. hypovolemia) or special accompanying medical conditions (e.g. muscle relaxation). There is an ongoing discussion about the clinical relevance of nociceptive stimulation in general anesthesia and the effect on patient outcome. Initial results for individual monitor systems show a reduction in opioid consumption and in postoperative pain level. Nevertheless, current evidence does not enable the routine use of nociception monitoring devices to be recommended as a clear beneficial effect on long-term outcome has not yet been proven.

One of the aims of this nationwide survey in Germany was therefore to determine how intensive care physicians deal with these problems. METHODS: From October 2019 to May 2020, we conducted a nationwide survey among German medical directors of intensive care units (ICU) addressing anticoagulation and drug-based prophylaxis of venous thromboembolism (VTE) in patients with sepsis and sepsis-induced coagulopathy. One focus was the procedure for patients with a pre-existing anticoagulation treatment or a previously known heparin-induced thrombocytopenia (HIT) type 2 (acute symptomatic vs. dating back years). RESULTS: In most of the participating ICUs pre-existing anticoagulation is largely continued with low molecular weight heparin preparations or unfractionated heparin. In patients with pre-existing HIT type 2 both acute symptomatic and dating back years, argatroban represents the drug of choice. There is a high degree of variability in the definition of the target values, usually being well above the range for pure VTE prophylaxis. CONCLUSION: Data on the continuation of anticoagulation beyond VTE prophylaxis with a subsequently increased risk of bleeding in patients with sepsis and septic shock is limited and treatment decisions are in many cases subject to individual consideration by the practitioner. The results of our survey imply the need for a systematic work-up of this topic in order to support daily practice in many ICUs with the required evidence.

Among other things, The Third International Consensus Definitions for Sepsis and Septic Shock (SEPSIS‑3 definition) will be implemented in it. This defines sepsis as a "life-threatening organ dysfunction caused by a dysregulated host response to infection". The aim of the present secondary analysis of a survey on the topic of "sepsis-induced coagulopathy" was to evaluate whether the SEPSIS‑3 definition, 4 years after its international introduction, has arrived in everyday clinical practice of intensive care units (ICU) run by anesthesiologists in Germany and thus the requirements for its use of the ICD-11 are given. METHODS: Between October 2019 and May 2020, we carried out a nationwide survey among German medical directors of ICUs. In a separate block of questions we asked about the definition of sepsis used in daily practice. In addition, we asked whether the quick-sequential (sepsis-related) organ failure assessment (qSOFA) score is used in screening for sepsis in the hospital to which to the participating ICU belongs. RESULTS: A total of 50 medical directors from anesthesiological ICUs took part in the survey. In total, the ICUs evaluated stated that they had around 14% of the high-care beds registered in Germany. The SEPSIS‑3 definition is integrated into everyday clinical practice at 78.9% of the university hospitals and 84.0% of the participating teaching hospitals. In contrast, the qSOFA screening test is only used by 26.3% of the participating university hospitals, but at least 52% of the teaching hospitals and 80% of the other hospitals. CONCLUSION: The data show that both SEPSIS‑3 and qSOFA have become part of everyday clinical practice in German hospitals. The cautious use of qSOFA at university hospitals with simultaneous broad acceptance of the SEPSIS‑3 definition can be interpreted as an indication that the search for a suitable screening test for sepsis has not yet been completed.

Teaching had to be digitalized within a very short time. This also affected the areas of anesthesiology, intensive care, emergency, pain and palliative care at the Department of Anesthesiology and Intensive Care Medicine at the University of Leipzig. OBJECTIVE: The aim of this questionnaire-based survey was to find out which courses can be digitalized from the students' point of view and which forms of teaching are associated with obstacles. In addition, we examined which technical infrastructure supports digitalization best. MATERIAL AND METHODS: In the course of digitalization the lecture series in the areas of palliative care and pain medicine had to be revised but also digital alternatives for seminars, simulation courses and bedside teaching had to be created. Video podcasts, digital learning material, educational films and video conferences were used for the digital implementation of the courses. Depending on the course, different digital methods were combined. In addition, a discussion forum for the exchange between faculty and students was established. An online evaluation was then carried out to assess the content. RESULTS: A total of 82 4th and 5th year medical students took part in the survey. More than 60% of students rated the learning effect of digital courses as "high" or "very high". Video podcasts of the lectures (45.1%) and digital bedside teaching (34.1%) were rated as the most effective ways of imparting knowledge. In particular, 92.7% of the surveyed students believed that the lectures could be replaced digitally on a permanent basis. For bedside teaching (3.7%) and emergency simulation course (1.2%) this is far less the case. In the majority of cases (56.1%), students needed 30-90 min daily for the preparation and post-processing of the contents. Just under 90% gave the digital courses offered by the hospital an overall grade of 1 or 2 (on a scale from 1 = best to 6 = worst). CONCLUSION: The SARS-CoV‑2 pandemic posed major challenges for graduate teaching. At the same time, however, it also helped to overcome often long-standing hurdles to the digitalization of teaching. In the course of the digital semester, different teaching formats could be digitalized to varying degrees: Lectures can be digitally reproduced particularly well from the students' perspective, whereas the digitalization of bedside teaching has not been possible in most cases.

OBJECTIVE: The aim of the present study was therefore to identify possible patient-specific risk factors that enable prediction of CDE. METHODS: Data were collected on 397 orthopedic patients undergoing shoulder surgery in the beach chair position. Routine anesthesia management and standard monitoring was used in all patients. Target value for the inspiratory oxygen concentration (FO) was set to 50% and for the end-tidal carbon dioxide partial pressure to 35-45 mm Hg. RSO was quantified using NIRS. The responsible anesthesiologist was blinded to the rSO data. A decrease in rSO > 20% or a value < 50% in the beach chair position was defined as CDE. Patients with and without CDE were analyzed with respect to different classifications, American Society of Anesthesiologists (ASA) and Revised Cardiac Risk Index (RCRI) as well as existing arterial hypertension and age. A value of p <0.05 was considered statistically significant. RESULTS: Patients with CDE (n = 238) were significantly more often classified as ASA > 2 (p = 0.01) and RCRI > 1 (p = 0.01), suffered more often from arterial hypertension (p = 0.01) and were older (median: 60 years compared to 55 years; p = 0.01) than patients without CDE (n = 159) in the beach chair position (Wilcoxon rank sum test). Arterial hypertension remained significant after removing the effect of age (p = 0.03) and RCRI classification (p = 0.04; two-way ANOVA multivariate analysis). CONCLUSION: On the basis of our study, patient-specific prognosis and risk factors for the occurrence of CDE, such as higher age, ASA > 2 and RCRI > 1 classification as well as pre-existing arterial hypertension could be determined. Arterial hypertension represents the main risk factor for the occurrence of CDE in the beach chair position. RCRI > 1 classification or age, however, only has an effect on the occurrence of pathological rSO values due to the greater probability of simultaneous arterial hypertension.

After stimulation-assisted puncture under sonographic control, 25 ml of local anesthetic (LA) were first administered and then the catheter was placed using the through the needle technique. Immediately after the administration of another 5 ml of local anesthetic via the inserted catheter, the patient showed symptoms of total spinal anesthesia, so that she had to be intubated and ventilated. The following computed tomographic diagnostics of the neck revealed an intrathecal misalignment of the plexus catheter, the tip of which was lying dorsal to the vertebral artery at the level of the 5/6 cervical vertebrae. The catheter could then be removed without any problems and there were no neurological sequelae. The use of ultrasound with clear identification of the nerve roots C5-C7 and the surrounding structures provides additional security when installing an intrascalene catheter. The spread of the LA should be traceable at all times using ultrasound and should otherwise be immediately terminated. Furthermore, a strict adherence to the needle position while inserting the catheter without manipulation of the needle depth is necessary. The first injection of the catheter has to be performed under controlled conditions, preferably connected to surveillance monitors with neurological monitoring of the awake patient and control of vital signs with direct access to the emergency equipment.

Until now, no holistic concept existed to use medical students as support for professionals in intensive care units (ICU) to avoid staff shortages in medical care. METHOD: In a large-scale pilot project 265 medical students were trained for an ICU assignment. The innovative training module was accompanied by a pre-post questionnaire for self-assessment of the skills learned. 22 weeks after the training module and still during the pandemic deployment, another questionnaire was used to evaluate experiences in deployment and the efficiency of the training module with respect to preparation for ICU deployment. RESULTS: The analysis revealed significant mean differences for all COVID-19-specific variables (safety dimension) in favor of the training module (n = 168). The deployment evaluation showed that the training concept was inconsistently assessed as preparation for the work deployment for 69 of the 89 deployed students in total (53% agreement/47% disagreement). CONCLUSION: The results show a good feasibility of an innovative training concept for medical students with respect to a pandemic deployment as assistants in intensive care units. The concept is suitable for providing additional helpers in intensive care units during a pandemic; however, the inconsistent evaluation indicates that the concept can be expanded and needs to be adapted.
