[Update 2022: interdisciplinary statement on airway management with supraglottic airway devices in pediatric emergency medicine-The laryngeal mask is and remains state of the art : Joint statement of the Institute for Emergency Medicine and Medicine Management (INM), the University Clinic Munich, LMU Munich, Germany, the Working Group for Pediatric Critical Care and Emergency Medicine of the German Interdisciplinary Society for Critical Care and Emergency Medicine (DIVI), the Medical Directors of Emergency Medical Services in Bavaria (ÄLRD), the Scientific Working Group for Pediatric Anesthesia (WAKKA) of the German Society for Anesthesiology and Intensive Care Medicine (DGAI), the Scientific Working Group for Emergency Medicine of the German Society for Anesthesiology and Intensive Care Medicine (DGAI) and the Society of Neonatology and Pediatric Critical Care Medicine (GNPI)]. / Update 2022: Interdisziplinäre Stellungnahme zum Atemwegsmanagement mit supraglottischen Atemwegshilfen in der Kindernotfallmedizin ­ die Larynxmaske ist und bleibt State of the Art : Gemeinsame Stellungnahme des Instituts für Notfallmedizin und Medizinmanagement (INM), Klinikum der Universität München, der Sektion Pädiatrische Intensiv- und Notfallmedizin der Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin (DIVI), des Ärztlicher Leiter Rettungsdienst Bayern (ÄLRD Bayern), des Wissenschaftlichen Arbeitskreises Kinderanästhesie (WAKKA) der Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin (DGAI), des Wissenschaftlichen Arbeitskreises Notfallmedizin der Deutschen Gesellschaft für Anästhesiologie und Intensivmedizin (DGAI) und der Gesellschaft für Neonatologie und Pädiatrische Intensivmedizin (GNPI).

BACKGROUND: Airway management with supraglottic airway devices (SGA) in life-threatening emergencies in children is increasingly being used. Different specifications of laryngeal masks (LM) and the laryngeal tube (LT) are commonly used devices for this purpose. We present a literature review and interdisciplinary consensus statement of different societies on the use of SGA in pediatric emergency medicine. MATERIAL AND METHODS: Literature review in the PubMed database and classification of studies according to the criteria of the Oxford Centre for Evidence-based Medicine. Levels and consensus finding within the group of authors. RESULTS: The evidence for successful applications of the various types of LM is significantly higher than for LT application. Reported smaller series of successful applications of LT are currently limited to selected research groups and centers. Especially for children below 10 kg body weight there currently exists insufficient evidence for the successful application of the LT and therefore its routine use cannot be recommended. SGAs used for emergencies should have a gastric drainage possibility. DISCUSSION: Considering the scientific data and the large clinical experience with the LM in medical routine and emergency situations in children currently only the LM can be recommended for alternative (i.e., non-intubation) emergency airway management in children. If alternative airway management is part of a local emergency strategy, the LM should be provided in all pediatric sizes (1, 1½, 2, 2½, 3) for out of hospital use and in hospital emergency use and all users should regularly be trained in its application.

Differences in training among prehospital emergency physicians in Germany.

Background: Germany has an interdisciplinary physician-based emergency medical service. Differences in training likely lead to different levels of expertise. Objectives: We assessed the number of manual procedures performed at the completion of training to determine level of experience of prehospital emergency physicians of different primary specialties. Materials and methods: Immediately after passing the board examination each examinee was asked to estimate the number of performed procedures for 26 manual skills. We compared the results with recommendations and data on learning manual skills. Results are presented as mean (standard deviation). Results: Endotracheal intubation via direct laryngoscopy was performed 1032 (739) times by anesthesiologists. Surgeons and internists performed 89 (89) and 77 (65) intubations, respectively. Intubation via video laryngoscopy was performed 79 (81) times by anesthesiologists, 11 (17) times by surgeons and 6 (11) times by internists. Surgeons had little experience in non-invasive ventilation, with 9 (19) performed procedures and had rarely used external pacemaker therapy or electrical cardioversion. In comparison, among all participants non-invasive ventilation was performed 152 (197) times, electrical cardioversion was performed 41 (103) times and an external pacemaker was used 6 (15) times. For other procedures the numbers did not markedly differ between the different specialties. Conclusion: The number of performed procedures markedly differed for some skills between different primary specialties. Recommendations regarding a procedural volume were not always met, suggesting missing expertise for some skills. A defined number of procedures should therefore be a formal requirement to be eligible for board certification in prehospital emergency medicine.

Impact of family presence during cardiopulmonary resuscitation on team performance and perceived task load: a prospective randomised simulator-based trial.

OBJECTIVES: Guidelines recommend family presence to be offered during cardiopulmonary resuscitation (CPR). Data on the effects of family presence on the quality of CPR and rescuers' workload and stress levels are sparse and conflicting. This randomised trial investigated the effects of family presence on quality of CPR, and rescuers' perceived stress. DESIGN: Prospective randomised single-blind trial. SETTING: Voluntary workshops of educational courses. PARTICIPANTS: 1085 physicians (565 men) randomised to 325 teams entered the trial. 318 teams completed the trial without protocol violation. INTERVENTIONS: Teams were randomised to a family presence group (n=160) or a control group (n=158) and to three versions of leadership: (a) designated at random, (b) designated by the team or (c) left open. Thereafter, teams were confronted with a simulated cardiac arrest which was video-recorded. Trained actors played a family member according a scripted role. MAIN OUTCOME MEASURES: The primary endpoint was hands-on time. Secondary outcomes included interaction time, rescuers' perceived task load and adherence to CPR algorithms. RESULTS: Teams interacted with the family member during 24 (17-36) % of the time spent for resuscitation. Family presence had no effect on hands-on time (88% (84%-91%) vs 89% (85%-91%); p=0.18). Family presence increased frustration (60 (30-75) vs 45 (30-70); p<0.001) and perceived temporal (75 (55-85) vs 70 (50-80); p=0.001) and mental demands (75 (60-85) vs 70 (55-80); p=0.009), but had no relevant effect on CPR performance markers. Leadership condition had no effects. CONCLUSIONS: Interacting with a family member occupied about a quarter of the time spent for CPR. While this additional task was associated with an increase in frustration and perceived temporal and mental demands, family presence had no relevant negative effect on the quality of CPR. TRIAL REGISTRATION NUMBER: DRKS00024759.

Effects of Intra-Abdominal Pressure on Lung Mechanics during Laparoscopic Gynaecology.

Investigating the relations between surgical actions and physiological reactions of the patient is essential for developing pre-emptive model-based systems. In this study, the effects of insufflating abdominal cavity with CO2 in laparoscopic gynaecology on the respiration system were analysed. Real-time recordings of anaesthesiology and surgical data of five subjects were acquired and processed, and the correlation between lung mechanics and the intra-abdominal pressure was evaluated. Alterations of ventilation settings undertaken by the anaesthesiologist were also considered. Experimental results demonstrated the high correlation with a mean Pearson coefficient of 0.931.Clinical Relevance- This study demonstrates the effects of intra-abdominal pressure during laparoscopy on lung mechanics and enables developing predictive models to promote a greater awareness in operating rooms.

The Janus kinase 1/2 inhibitor ruxolitinib in COVID-19 with severe systemic hyperinflammation.

A subgroup of patients with severe COVID-19 suffers from progression to acute respiratory distress syndrome and multiorgan failure. These patients present with progressive hyperinflammation governed by proinflammatory cytokines. An interdisciplinary COVID-19 work flow was established to detect patients with imminent or full blown hyperinflammation. Using a newly developed COVID-19 Inflammation Score (CIS), patients were prospectively stratified for targeted inhibition of cytokine signalling by the Janus Kinase 1/2 inhibitor ruxolitinib (Rux). Patients were treated with efficacy/toxicity guided step up dosing up to 14 days. Retrospective analysis of CIS reduction and clinical outcome was performed. Out of 105 patients treated between March 30th and April 15th, 2020, 14 patients with a CIS ≥ 10 out of 16 points received Rux over a median of 9 days with a median cumulative dose of 135 mg. A total of 12/14 patients achieved significant reduction of CIS by ≥25% on day 7 with sustained clinical improvement in 11/14 patients without short term red flag warnings of Rux-induced toxicity. Rux treatment for COVID-19 in patients with hyperinflammation is shown to be safe with signals of efficacy in this pilot case series for CRS-intervention to prevent or overcome multiorgan failure. A multicenter phase-II clinical trial has been initiated (NCT04338958).

[Perioperative infusion therapy in children : Are infusion sets with precision flow regulators suitable for pediatric anesthesia?] / Perioperative Infusionstherapie im Kindesalter : Eignen sich Infusionssysteme mit Laufratenbeschränkung für die Kinderanästhesie?

BACKGROUND: Infusion sets with precision flow regulators are frequently used in children undergoing surgery in order to control the perioperative administration of fluids. There are no data about the safety and accuracy of these infusion sets. A study was therefore conducted to compare adjusted and actual flow rates of three different infusion sets with precision flow regulators under standardized conditions. METHODS: The study evaluated three different infusion sets with precision flow regulators each at two different static levels. The actual flow rates of 5 infusions were recorded each time for adjusted flow rates of 50 ml/h, 100 ml/h, 150 ml/h, 200 ml/h and 250 ml/h over 1 h. Statistical analysis was performed with Excel (Excel, Microsoft Corporation, Redmond, WA, USA) and SOFA (Paton-Simpson and Associates Ltd., USA). The results are presented as means (standard deviation). RESULTS: For the adjusted flow rates of 50, 100, 150, 200 and 250 ml/h, actual flow rates were 107 (5.3), 174.8 (6.5), 255.8 (10.2), 312.4 (15.7) and 362.6 (20.2) ml/h for the Frekadrop® infusion set at a static level of 128 cm and 83.8 (4.4), 147.8 (5.5), 197 (12.4), 257.2 (4.97) and 311.6 (17.9) ml/h at a static level of 100 cm, respectively. For the Exadrop® infusion set actual flow rates were 88.6 (6.9), 131.2 (14.1), 224.4 (14.1), 296.6 (27.6) and 330.4 (22.4) ml/h at a static level of 128 cm and 54 (4), 82.4 (10.2), 138.8 (15.7), 209.4 (36.8) and 249 (12) ml/h at a static level of 76 cm, respectively. For the D-Flo infusion set actual flow rates were 95.6 (2.8), 167.6 (29), 217.8 (9.9), 281.6 (10.6) and 396.8 (37.5) ml/h at a static level of 128 cm and 69.2 (4.4), 110.2 (12.6), 169.2 (6), 205.2 (14) and 243 (15.9) ml/h at a static level of 80 cm, respectively. CONCLUSION: The actual flow rates differed considerably from the adjusted flow rates in the evaluated infusion sets. The flow rates substantially depended on the static level of the infusion. First and foremost, regulation of the administered infusion volume does not seem to be reliable when using an infusion set with a precision flow regulator.

[Tracheal bronchus and contralateral pneumonectomy]. / Trachealer Bronchusabgang und kontralaterale Pneumonektomie.

One-lung ventilation is a standard procedure for many types of lung surgery. The anesthesiologist can be challenged if unknown anomalies of the bronchial tree occur. We report a patient with a tracheal bronchus on the right side presenting for left pneumonectomy, and present one possible solution to airway management.

[Interdisciplinary consensus statement on alternative airway management with supraglottic airway devices in pediatric emergency medicine: Laryngeal mask is state of the art]. / Interdisziplinär konsentierte Stellungnahme zum Atemwegsmanagement mit supraglottischen Atemwegshilfen in der Kindernotfallmedizin: Larynxmaske ist State-of-the-art.

BACKGROUND: Airway management with supraglottic airway devices (SGA) in life-threatening emergencies involving children is becoming increasingly more important. The laryngeal mask (LM) and the laryngeal tube (LT) are devices commonly used for this purpose. This article presents a literature review and consensus statement by various societies on the use of SGA in pediatric emergency medicine. MATERIAL AND METHODS: Literature search in the database PubMed and classification of studies according to the criteria of the Oxford Centre for Evidence-based Medicine levels of evidence. RESULTS: The evidence for successful application of the various types of LM is significantly higher than for LT application. Reports of smaller series of successful applications of LT are currently limited to selected research groups and centers. Insufficient evidence currently exists for the successful application of the LT especially for children below 10 kg body weight and, therefore, its routine use cannot currently be recommended. SGAs used for emergencies should have a possibility for gastric drainage. DISCUSSION: Considering the scientific data and the large clinical experience with the LM in medical routine and emergency situations in children, currently only the LM can be recommended for alternative (i.e. non-intubation) airway management in children. If alternative airway management is part of a local emergency strategy, the LM should be provided in all pediatric sizes (1, 1.5, 2, 2.5, 3, 4 and 5) for prehospital and in-hospital emergency use and all users should be regularly trained in its application.

[Implementation of a rational standard of hygiene for preparation of operating rooms]. / Implementierung eines rationalen Hygienestandards zur Aufbereitung von Operationssälen.

BACKGROUND: The assurance of high standards of care is a major requirement in German hospitals while cost reduction and efficient use of resources are mandatory. These requirements are particularly evident in the high-risk and cost-intensive operating theatre field with multiple process steps. The cleaning of operating rooms (OR) between surgical procedures is of major relevance for patient safety and requires time and human resources. The hygiene procedure plan for OR cleaning between operations at the university hospital in Göttingen was revised and optimized according to the plan-do-check-act principle due to not clearly defined specifications of responsibilities, use of resources, prolonged process times and increased staff engagement. METHODS: The current status was evaluated in 2012 as part of the first step "plan". The subsequent step "do" included an expert symposium with external consultants, interdisciplinary consensus conferences with an actualization of the former hygiene procedure plan and the implementation process. All staff members involved were integrated into this management change process. The penetration rate of the training and information measures as well as the acceptance and compliance with the new hygiene procedure plan were reviewed within step "check". The rates of positive swabs and air sampling as well as of postoperative wound infections were analyzed for quality control and no evidence for a reduced effectiveness of the new hygiene plan was found. After the successful implementation of these measures the next improvement cycle ("act") was performed in 2014 which led to a simplification of the hygiene plan by reduction of the number of defined cleaning and disinfection programs for preparation of the OR. RESULTS: The reorganization measures described led to a comprehensive commitment of the hygiene procedure plan by distinct specifications for responsibilities, for the course of action and for the use of resources. Furthermore, a simplification of the plan, a rational staff assignment and reduced process times were accomplished. Finally, potential conflicts due to an insufficient evidence-based knowledge of personnel was reduced. CONCLUSION: This present project description can be used by other hospitals as a guideline for similar changes in management processes.

[Perioperative thermal management in Germany varies depending on the hospital size]. / Perioperatives Wärmemanagement in Abhängigkeit von der Krankenhausgröße in Deutschland.

BACKGROUND: Improvement of quality of care and patient safety while decreasing costs are major challenges in healthcare systems. This challenge includes the avoidance of perioperative hypothermia to reduce the associated adverse effects, length of stay and treatment costs. Due to the medical and economic relevance the national S3 guidelines for the prevention of perioperative hypothermia were recently published. AIM: This study presents and analyses the reality of utilization of thermal management in German hospitals depending on the size of the hospital, which is based on the number of beds. MATERIAL AND METHODS: Based on the data of an online survey among all members of the German Society of Anesthesiology and Intensive Care Medicine about perioperative thermal management, a subgroup analysis differentiating between the size of hospitals was performed. The survey included questions about the structural and organizational conditions, the practical implementation of temperature measurement and warming therapy and the developmental status of clinical standard operating procedures (SOP) and educational training. RESULTS: Comparing the structural quality, major differences were found with respect to the availability of core body temperature measurement and the provision of warming devices especially at different peripheral anesthesia workplaces as well as the existence of SOPs and educational training. The availability increased with hospital size. With respect to process quality, the frequency of prewarming increased with hospital size as well as the frequency of intraoperative temperature measurements during different anesthesia procedures. CONCLUSION: Major differences were found in several aspects of perioperative thermal management depending on the hospital size. The main potential for improvement was found in smaller hospitals. Developmental needs primarily exist in the configuration of peripheral anesthesia workplaces, educational training, implementation of SOPs and prewarming of patients.

Transfer of airway skills from manikin training to patient: success of ventilation with facemask or LMA-Supreme(TM) by medical students.

During emergency care, the ability to ventilate the patient's lungs is a crucial skill. Supraglottic airway devices have an established role in emergency care, and manikin trials have shown that placement is easy even for inexperienced users. However, there is current discussion as to what extent these results can be transferred to patients. We studied the transfer of skills learnt on a manikin to the clinical situation in novice medical students during their anaesthesia rotation. They were required to ventilate the lungs of a manikin using a facemask and then position a supraglottic airway device (LMA-Supreme™) and ventilate the lungs. This process was then repeated on anaesthetised patients, with standard ventilator settings to assess adequacy of ventilation. Sixty-three students participated in the manikin study. The success rate for ventilating the lungs was 100% for both devices, but the mean (SD) time to achieve successful ventilation was 27.8 (24.4) s with the facemask compared with 38.6 (22.0) s with the LMA-Supreme (p = 0.008). Fifty-one of the students progressed to the second part of the study. In anaesthetised patients, the success rate for ventilating the lungs was lower for the facemask, 27/41 (66%) compared with the LMA-Supreme 37/41 (90%, p = 0.006). For 26 students who succeeded with both devices, the tidal volume was lower using the facemask, 431 (192) ml compared with the LMA-Supreme 751 (221) ml (p = 0.001), but the time to successful ventilation did not differ, 60.0 (26.2) s vs 57.3 (26.6) s (p = 0.71). We conclude that the results obtained in manikin studies cannot be transferred directly to the clinical situation and that guidelines should take this into account. Based on our findings, a supraglottic airway device may be preferable to a facemask as the first choice for inexperienced emergency caregivers.

[Legal position of non-medical personnel in hospitals]. / Rechtliche Stellung nichtärztlichen Personals im Krankenhaus.

There are currently many assistant professions in the German healthcare system which have either a more nursing or a more medical character. All these assistant professions have in common that as yet they do not require uniform training criteria but members of these professions undertake some aspects of medical activities. At the center lies the difficulty of more political than legal discussion on whether members of these assistant professions and also nursing personnel are allowed to or should undertake medical activities. This article illuminates the legal status quo.

[Efficacy of a novel warming blanket: prospective randomized trial]. / Effektivität einer neuen Wärmedecke: Prospektive randomisierte Studie.

BACKGROUND: Perioperative hypothermia is a common complication of general anesthesia and occurs in up to 50 % of patients during ear, nose and throat (ENT) surgery. In this prospective, randomized controlled study the hypothesis that a new conductive warming blanket (Barrier® EasyWarm®, Mölnlycke Health Care Erkrath, Germany) is better in reducing the incidence of perioperative hypothermia in ENT surgery than insulation with a conventional hospital duvet alone was tested. MATERIALS AND METHODS: After approval of the local ethics committee and written informed consent 80 patients with a planned procedure time between 1 and 3 h were recruited. Anesthesia was induced and maintained using propofol, remifentanil and rocuronium and the core temperature was measured using an esophageal temperature probe. Patients in the study group were warmed at least 30 min prior to induction of anesthesia using the novel warming blanket (Barrier® EasyWarm®) and patients in the control group were insulated with a standard hospital duvet. Data were tested using Fisher's exact test, Student's t-test or the Mann-Whitney U-test as appropriate. Time-dependent changes in core temperature were evaluated using repeated measures analysis of variance (ANOVA) and post hoc Scheffé's test. Results are expressed as mean ± SD or as median and interquartile range (IQR) as appropriate. A p < 0.05 was considered to be statistically significant. RESULTS: The ANOVA did not identify a significantly higher core temperature in the study group at any time point. Furthermore, Fisher's exact test showed no differences in the incidence of intraoperative (12 out of 29 versus 10 out of 32 patients, p = 0.44) or postoperative hypothermia (12 out of 29 versus 9 out of 32 patients, p = 0.30) between the groups. No adverse effects were observed. CONCLUSIONS: In the studied patient group the new conductive warming blanket (Barrier® EasyWarm®) showed no superiority compared to conventional thermal insulation alone.

[Video laryngoscopy olé! Time to say good bye to direct and flexible intubation?]. / Videolaryngoskopie olé! Direkte und flexible Intubationsverfahren ade?

A number of video laryngoscopy systems have been introduced into anesthetic practice in recent years. Due to the technical concepts of these systems exposure of the laryngeal structures is usually better than with direct laryngoscopy, both in normal airways as well as in those that are difficult to manage. With the increasing use of video laryngoscopy it seems as if direct laryngoscopy and flexible fibrescopic intubation are at risk of becoming redundant. This article describes current developments and discusses why expertise in direct laryngoscopy and flexible fibrescopic intubation should be maintained, particularly by experts in airway management.

Magnetic resonance imaging study of the in vivo position of the extraglottic airway devices i-gel™ and LMA-Supreme™ in anaesthetized human volunteers.

BACKGROUND: Exact information on the anatomical in situ position of extraglottic airway (EGA) devices is lacking. We used magnetic resonance imaging (MRI) to visualize the positions of the i-gel™ and the LMA-Supreme™ (LMA-S) relative to skeletal and soft-tissue structures. METHODS: Twelve volunteers participated in this randomized, prospective, cross-over study. Native MRI scans were performed before induction of anaesthesia. Anaesthesia was induced, and the two EGAs were inserted in a randomized sequence. Their positions were assessed functionally, optically by fibrescope, and with MRI scans of the head and neck. RESULTS: The LMA-S protruded deeper into the upper oesophageal sphincter than the i-gel™ (P<0.001). Both devices reduced the area of the glottic aperture (P<0.001), and the LMA-S had the largest effect (P=0.049). The i-gel™ significantly compressed the tongue (P<0.001). Both devices displaced the hyoid bone ventrally (P<0.001); the i-gel™ to a greater degree (P=0.029). The fibreoptically determined position of the bowl of the devices was identical. CONCLUSIONS: The LMA-S and i-gel™ differ significantly with regard to in situ position and spatial relationship with adjacent structures assessed by MRI, despite similar clinical and fibreoptical findings. This could be relevant with regard to risk of aspiration, glottic narrowing, and airway resistance and soft-tissue morbidity.

[Comments on the 2010 guidelines on cardiopulmonary resuscitation of the European Resuscitation Council]. / Kommentar zu den Leitlinien 2010 zur kardiopulmonalen Reanimation des European Resuscitation Council.

ADULTS: Administer chest compressions (minimum 100/min, minimum 5 cm depth) at a ratio of 30:2 with ventilation (tidal volume 500-600 ml, inspiration time 1 s, F(I)O2 if possible 1.0). Avoid any interruptions in chest compressions. After every single defibrillation attempt (initially biphasic 120-200 J, monophasic 360 J, subsequently with the respective highest energy), chest compressions are initiated again immediately for 2 min independent of the ECG rhythm. Tracheal intubation is the optimal method for securing the airway during resuscitation but should be performed only by experienced airway management providers. Laryngoscopy is performed during ongoing chest compressions; interruption of chest compressions for a maximum of 10 s to pass the tube through the vocal cords. Supraglottic airway devices are alternatives to tracheal intubation. Drug administration routes for adults and children: first choice i.v., second choice intraosseous (i.o.). Vasopressors: 1 mg epinephrine every 3-5 min i.v. After the third unsuccessful defibrillation amiodarone (300 mg i.v.), repetition (150 mg) possible. Sodium bicarbonate (50 ml 8.4%) only for excessive hyperkaliemia, metabolic acidosis, or intoxication with tricyclic antidepressants. Consider aminophylline (5 mg/kgBW). Thrombolysis during spontaneous circulation only for myocardial infarction or massive pulmonary embolism; during on-going cardiopulmonary resuscitation (CPR) only when indications of massive pulmonary embolism. Active compression-decompression (ACD-CPR) and inspiratory threshold valve (ITV-CPR) are not superior to good standard CPR. CHILDREN: Most effective improvement of outcome by prevention of full cardiorespiratory arrest. Basic life support: initially five rescue breaths, followed by chest compressions (100-120/min depth about one third of chest diameter), compression-ventilation ratio 15:2. Foreign body airway obstruction with insufficient cough: alternate back blows and chest compressions (infants), or abdominal compressions (children >1 year). Treatment of potentially reversible causes: ("4 Hs and 4 Ts") hypoxia and hypovolaemia, hypokalaemia and hyperkalaemia, hypothermia, and tension pneumothorax, tamponade, toxic/therapeutic disturbances, thrombosis (coronary/pulmonary). Advanced life support: adrenaline (epinephrine) 10 µg/kgBW i.v. or i.o. every 3-5 min. Defibrillation (4 J/kgBW; monophasic or biphasic) followed by 2 min CPR, then ECG and pulse check. NEWBORNS: Initially inflate the lungs with bag-valve mask ventilation (p(AW) 20-40 cmH2O). If heart rate remains <60/min, start chest compressions (120 chest compressions/min) and ventilation with a ratio 3:1. Maintain normothermia in preterm babies by covering them with foodgrade plastic wrap or similar. POSTRESUSCITATION PHASE: Early protocol-based intensive care stabilization; initiate mild hypothermia early regardless of initial cardiac rhythm [32-34°C for 12-24 h (adults) or 24 h (children); slow rewarming (<0.5°C/h)]. Consider percutaneous coronary intervention (PCI) in patients with presumed cardiac ischemia. Prediction of CPR outcome is not possible at the scene, determine neurological outcome <72 h after cardiac arrest with somatosensory evoked potentials, biochemical tests and neurological examination. ACUTE CORONARY SYNDROME: Even if only a weak suspicion of an acute coronary syndrome is present, record a prehospital 12-lead ECG. In parallel to pain therapy, administer aspirin (160-325 mg p.o. or i.v.) and clopidogrel (75-600 mg depending on strategy); in ST-elevation myocardial infarction (STEMI) and planned PCI also prasugrel (60 mg p.o.). Antithrombins, such as heparin (60 IU/kgBW, max. 4000 IU), enoxaparin, bivalirudin or fondaparinux depending on the diagnosis (STEMI or non-STEMI-ACS) and the planned therapeutic strategy. In STEMI define reperfusion strategy depending on duration of symptoms until PCI, age and location of infarction. TRAUMA: In severe hemorrhagic shock, definitive control of bleeding is the most important goal. For successful CPR of trauma patients a minimal intravascular volume status and management of hypoxia are essential. Aggressive fluid resuscitation, hyperventilation and excessive ventilation pressure may impair outcome in patients with severe hemorrhagic shock. TRAINING: Any CPR training is better than nothing; simplification of contents and processes is the main aim.

[Death due to (no) airway. Adverse events by out-of-hospital airway management?]. / Tod durch (k)einen Atemweg. Trauma durch die präklinische Atemwegssicherung?

Securing the airway is a rarely performed procedure in the out-of-hospital setting. In recent years evidence has been accumulated indicating that out-of-hospital airway management is more challenging as compared to elective situations even for experienced health care providers. Furthermore, several authors have questioned the benefit of out-of-hospital tracheal intubation. This review argues the problems regarding out-of-hospital airway management studies and discusses potential solutions which may improve out-of-hospital health care.

[Extraglottic airway devices in the intensive care unit]. / Extraglottische Atemwegshilfen auf der Intensivstation.

Extraglottic airway devices (EGA) are not only used in routine anaesthesia practice, they also have a distinct value for in-hospital and out-of-hospital difficult airway management. In the environment of the intensive care unit (ICU) EGA are not used on a regular basis. However, expertise and knowledge regarding EGA coming from the operating theatre or the out-of-hospital setting may also be of value for the ICU setting. This review presents the potential indications for EGA on the ICU for the management of difficult airway situations as well as during percutaneous tracheotomy. Furthermore, the possible advantages of EGA during postoperative recovery from anaesthesia as well as termination of controlled ventilation for intensive care patients are discussed.
