Preoperative assessment of adults undergoing elective noncardiac surgery: Updated guidelines from the European Society of Anaesthesiology and Intensive Care.

When considering whether a patient is fit for surgery, a comprehensive patient assessment represents the first step for an anaesthetist to evaluate the risks associated with the procedure and the patient's underlying diseases, and to optimise (whenever possible) the perioperative surgical journey. These guidelines from the European Society of Anaesthesiology and Intensive Care Medicine (ESAIC) update previous guidelines to provide new evidence on existing and emerging topics that consider the different aspects of the patient's surgical path. A comprehensive literature review focused on organisation, clinical facets, optimisation and planning. The methodological quality of the studies included was evaluated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. A Delphi process agreed on the wording of recommendations, and clinical practice statements (CPS) supported by minimal evidence. A draft version of the guidelines was published on the ESAIC website for 4 weeks, and the link was distributed to all ESAIC members, both individual and national, encompassing most European national anaesthesia societies. Feedback was gathered and incorporated into the guidelines accordingly. Following the finalisation of the draft, the Guidelines Committee and ESAIC Board officially approved the guidelines. In the first phase of the guidelines update, 17 668 titles were initially identified. After removing duplicates and restricting the search period from 1 January 2018 to 3 May 2023, the number of titles was reduced to 16 774, which were then screened, yielding 414 abstracts. Among these, 267 relevant abstracts were identified from which 204 appropriate titles were selected for a comprehensive GRADE analysis. Additionally, the study considered 4 reviews, 16 meta-analyses, 9 previously published guidelines, 58 prospective cohort studies and 83 retrospective studies. The guideline provides 55 evidence-based recommendations that were voted on by a Delphi process, reaching a solid consensus (>90% agreement). This update of the previous guidelines has covered new organisational and clinical aspects of the preoperative anaesthesia assessment to provide a more objective evaluation of patients with a high risk of postoperative complications requiring intensive care. Telemedicine and more predictive preoperative scores and biomarkers should guide the anaesthetist in selecting the appropriate preoperative blood tests, x-rays, and so forth for each patient, allowing the anaesthetist to assess the risks and suggest the most appropriate anaesthetic plan. Each patient should have a tailored assessment of their fitness to undergo procedures requiring the involvement of an anaesthetist. The anaesthetist's role is essential in this phase to obtain a broad vision of the patient's clinical conditions, to coordinate care and to help the patient reach an informed decision.

Sustainability-national and international initiatives in intensive care and emergency medicine

Climate change with global warming, natural disasters, species extinction and soil erosion is doubly relevant for medicine: On the one hand, heat waves, floods and other natural disasters lead to new disease patterns to which healthcare systems must adapt. On the other hand, the global healthcare system itself contributes to these effects, as it is estimated that the CO2 footprint of all healthcare facilities accounts for around 5% of global greenhouse gas emissions. National and international initiatives to promote sustainability concepts in intensive care and emergency medicine. Research on homepages of national and international (specialist) societies dealing with intensive and emergency care medicine and corresponding PubMed search (sustainability and climate change and emergency or intensive care medicine). Six of the 12national specialist societies surveyed have taken initiatives on sustainability, notable among them the initiative of Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) for anew registration of the S1guideline "Sustainability in intensive care and emergency medicine". On the international scene, the activities of the Australian and New Zealand Intensive Care Society (ANZICS) with numerous publications on the topic of sustainability in intensive care medicine and the practical guide "Abeginners guide to sustainability in intensive care medicine" as well as the European Society of Anaesthesiology and Intensive Care (ESAIC) with aconsensus paper on sustainability should be highlighted. At the national level, initiatives on sustainability (guidelines, working groups, forums) are emerging and are attracting increasing attention and activity. The umbrella organization of German Intensive Care Medicine, the Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin (DIVI), has so far shown no (discernible) activity; there is an urgent need for action here, and health policy and the German Medical Association should also become (even) more involved in reducing the CO2 footprint in the healthcare sector. Internationally, there are anumber of societies and institutions that are promoting the topic of "sustainability", although astronger focus on the area of intensive care and emergency medicine would also be desirable here.

Regional anaesthetic techniques in 14 Slovenian obstetric units between 2013 and 2021: where are we and where are we going?

Background: The use of regional anaesthetic techniques for caesarean section and labour analgesia is necessary for quality-driven obstetric anaesthesia as required by European minimum standards for obstetric analgesia and anaesthesia departments, which were issued by the European Society of Anaesthesiology and Intensive Therapy in 2020. The aim of this article is to evaluate the rate of caesarean sections performed using regional anaesthetic techniques and the rates of epidural, remifentanil-PCA, and meperidine analgesia for managing labour pain across the 14 Slovenian obstetric units, respectively. Methods: Data from the Slovenian National Perinatal Information System (NPIS) from 2013 to 2021 were analysed. Results: Spinal anaesthesia was used as a primary anaesthetic method (> 50% of elective caesarean sections) in a half of Slovenian obstetric units. For emergency caesarean sections, regional anaesthetic methods (spinal and epidural) were used in > 50% parturients in 3 obstetric units. Eight obstetric units had an epidural rate of >10%. The use of epidural analgesia has progressively increased in 9 of 14 obstetric units. Remifentanil has been routinely used in 6 obstetric units. Accordingly, the consumption of meperidine has dropped in all but one obstetric unit in Slovenia. Conclusion: In the past decade, considerable progress has been observed in obstetric anaesthesia practice in Slovenia. This is evident from the increased use of regional anaesthesia for caesarean section and labour analgesia. However, there are considerable discrepancies in anaesthetic practices between different obstetric units in Slovenia, a situation the parturients should be informed of well in advance to be able to choose the obstetric unit according to their labour and delivery preferences. In order to avoid the differences in the quality and accessibility of anaesthetic practice between units, it is necessary to increase the number of anaesthesiologists involved in obstetric anaesthesia to ensure 24/7 service of labour analgesia to be able to fulfill minimum European standards for obstetric analgesia and anaesthesia departments.

A survey and analysis of peri-operative quality indicators promoted by National Societies of Anaesthesiologists in Europe: The EQUIP project.

To capture preventable peri-operative patient harm and guide improvement initiatives, many quality indicators (QIs) have been developed. Several National Anaesthesiologist Societies (NAS) in Europe have implemented quality indicators. To date, the definitions, validity and dissemination of such quality indicators, and their comparability with validated published indicators are unknown. The aim of this study was to identify all quality indicators promoted by NAS in Europe, to assess their characteristics and to compare them with published validated quality indicators. A cross-sectional study with mixed methods analysis. Using a survey questionnaire, representatives of 37 NAS were asked if their society provided quality indicators to their members and, if so, to provide the list, definitions and details of quality indicators. Characteristics of reported quality indicators were analysed. The 37 NAS affiliated with the European Society of Anaesthesiology and Intensive Care (ESAIC) at the time. Data collection, translations: March 2018 to February 2020. Representatives of all 37 NAS completed the survey. QIs reported by NAS. Only 12 (32%) of the 37 NAS had made a set of quality indicators available to their members. Data collection was mandatory in six (16.2%) of the 37 countries. We identified 163 individual quality indicators, which were most commonly descriptive (60.1%), anaesthesia-specific (50.3%) and related to intra-operative care (21.5%). They often measured structures (41.7%) and aspects of safety (35.6%), appropriateness (20.9%) and prevention (16.6%). Patient-centred care (3.7%) was not well covered. Only 11.7% of QIs corresponded to published validated or well established quality indicator sets. Few NAS in Europe promoted peri-operative quality indicators. Most of them differed from published sets of validated indicators and were often related to the structural dimension of quality. There is a need to establish a European-wide comprehensive core set of usable and validated quality indicators to monitor the quality of peri-operative care. No registration.

Factors affecting adherence to recommendations on pre-operative cardiac testing: A cohort study.

Cardiac risk evaluation prior to noncardiac surgery is fundamental to tailor peri-operative management to patient's estimated risk. Data on the degree of adherence to guidelines in patients at cardiovascular risk in Europe and factors influencing adherence are underexplored. The aim of this analysis was to describe the degree of adherence to [2014 European Society of Cardiology (ESC)/European Society of Anaesthesiology (ESA) guidelines] recommendations on rest echocardiography [transthoracic echocardiography (TTE)] and to stress imaging prior to noncardiac surgery in a large European sample and to assess factors potentially affecting adherence. Secondary analysis of a multicentre, international, prospective cohort study (MET-REPAIR). Twenty-five European centres of all levels of care that enrolled patients between 2017 and 2020. With elevated cardiovascular risk undergoing in-hospital elective, noncardiac surgery. (Non)adherence to each pre-operative TTE and stress imaging recommendations classified as guideline-adherent, overuse and underuse. We performed descriptive analysis. To explore the impact of patients' sex, age, geographical region, and hospital teaching status, we conducted multivariate multinominal regression analysis. Out of 15 983 patients, 15 529 were analysed (61% men, mean age 72 ± 8 years). Overuse (conduction in spite of class III) and underuse (nonconduction in spite of class I recommendation) for pre-operative TTE amounted to 16.6% (2542/15 344) and 6.6% (1015/15 344), respectively. Stress imaging overuse and underuse amounted to 1.7% (241/14 202) and 0.4% (52/14 202) respectively. Male sex, some age categories and some geographical regions were significantly associated with TTE overuse. Male sex and some regions were also associated with TTE underuse. Age and regions were associated with overuse of stress imaging. Male sex, age, and some regions were associated with stress imaging underuse. Adherence to pre-operative stress imaging recommendation was high. In contrast, adherence to TTE recommendations was moderate. Both patients' and geographical factors affected adherence to joint ESC/ESA guidelines. NCT03016936.

STUDY TO COMPARE FASTING GASTRIC VOLUME USING ULTRASOUND IN DIABETIC AND NON DIABETIC PATIENTS POSTED FOR ELECTIVE SURGERIES

Objective: To study the comparison of fasting gastric volume using ultrasound in diabetic and nondiabetic patients in elective surgeries. To compare the incidence of delayed gastric emptying in diabetic and nondiabetic after standard fasting guidelines Material and Methods: After institutional ethical committee approval, CTRI registration and patient consent, prospective study was conducted in 30 diabetic and 30 non-diabetic patients aged 30-60years of American society of anesthesiologists- physical status I-III having similar fasting intervals. Pre operatively, quantitative assessments of gastric antrum in supine and right lateral decubitus (RLD) positions were performed using curvilinear probe in accordance to standard gastric scanning. USG grade, cross-sectional area (CSA) of the antrum and gastric volume were calculated. The gastric antrum was classified as Grade 0, 1 or 2, signifying empty antrum, fluid in RLD position only and antral fluid in both supine and RLD positions, respectively. Results:The CSA of 2.35 ± 1.07 cm2 and 3.51 ± 1.4 cm2 in diabetic were significantly higher (P = 0.001) than 1.37 ± 0.32 cm2 and 2.19 ± 1.15 cm2 of control, in supine and RLD positions, respectively. GV was 3.85± 20.06 ml in control group and 6.5±23.51 ml in diabetic group. Conclusion: Diabetic patients have higher gastric antral cross-sectional area and gastric volumes as observed by gastric ultrasound than the non-diabetic patients. Reference - 1.

A Practical Dosing Algorithm for Deep Neuromuscular Blockade during Total Intravenous Anesthesia: ROCURITHM.

The number of trials investigating the effects of deep neuromuscular blockade (NMB) on surgical conditions and patient outcomes is steadily increasing. Consensus on which surgical procedures benefit from deep NMB (a posttetanic count [PTC] of 1 to 2) and how to implement it has not been reached. The European Society of Anaesthesiology and Intensive Care does not advise routine application but recommends use of deep NMB to improve surgical conditions on indication. This study investigates the optimal dosing strategy to reach and maintain adequate deep NMB during total intravenous anesthesia. Data from three trials investigating deep NMB during laparoscopic surgery with total intravenous anesthesia (n = 424) were pooled to analyze the required rocuronium dose, when to start continuous infusion, and how to adjust. The resulting algorithm was validated (n = 32) and compared to the success rate in ongoing studies in which the algorithm was not used (n = 180). The mean rocuronium dose based on actual bodyweight for PTC 1 to 2 was (mean ± SD) 1.0 ± 0.27 mg · kg-1 ·h-1 in the trials, in which mean duration of surgery was 116 min. An induction dose of 0.6 mg ·kg-1 led to a PTC of 1 to 5 in a quarter of patients after a mean of 11 min. The remaining patients were equally divided over too shallow (additional bolus and direct start of continuous infusion) or too deep; a 15-min wait after PTC of 0 for return of PTC to 1 or higher. Using the proposed algorithm, a mean 76% of all 5-min measurements throughout surgery were on target PTC 1 to 2 in the validation cohort. The algorithm performed significantly better than anesthesiology residents without the algorithm, even after a learning curve from 0 to 20 patients (42% on target, P ≤ 0.001, Cohen's d = 1.4 [95% CI, 0.9 to 1.8]) to 81 to 100 patients (61% on target, P ≤ 0.05, Cohen's d = 0.7 [95% CI, 0.1 to 1.2]). This study proposes a dosing algorithm for deep NMB with rocuronium in patients receiving total intravenous anesthesia.

Anaesthesia praCtice for Caesarean dElivery Snapshot Study (ACCESS): Protocol and baseline characteristics of registered centres.

Specific guidelines to manage caesarean delivery anaesthesia are lacking. A European multicentre study, ACCESS investigates caesarean delivery anaesthesia management in European centres. In order to identify ACCESS participating centres, a registration survey was created. The aim of the current report is to describe the characteristics of ACCESS study participating centres, the rationale for the ACCESS study and the study methodology. The ACCESS study is a European multicentre cross-sectional study to describe anaesthesia management for caesarean delivery (CD) using a snapshot (2-week) design. The ACCESS registration survey gathered: contact details for National Coordinators (NC); Lead Investigators (LI) per centre; centre annual CD volume; expected no. of CD during 2-week snapshot window; centre practice information; data collection language. The ACCESS registration survey was launched July 2022 (Google Forms, Google Inc., Mountain View, CA, USA) and distributed through personal connections, national and international societies, social media networks, during Euroanaesthesia 2023, through the European Society of Anaesthesiology and Intensive Care newsletter. The ACCESS registration survey identified Lead Investigators for 418 centres, in 32 countries, representing an anticipated number of 15,073 CD cases over the planned 12-month study period. A median (range) of 20 (2 to 400) CD cases are anticipated per centre during the 2-week snapshot window. Most 366/418 (87.6%) centres are small, ≤2000 annual CD cases, 42 are medium 2000-5000 cases and 10 are large, ≥5000 annual CD cases. Registered centres reported in 134 (32.0%) centres that anaesthesia for caesarean delivery is performed mostly by a specialist obstetric anaesthesiologist. The ACCESS registration survey revealed variability in volume and CD practice as well as training-levels and staffing among European countries. The ACCESS study (https://www.access-study.org/) aims to generate practice data to guide CD anaesthetic management strategies.

Clinical guideline on reversal of direct oral anticoagulants in patients with life threatening bleeding.

Anticoagulation is essential for the treatment and prevention of thromboembolic events. Current guidelines recommend direct oral anticoagulants (DOACs) over vitamin K antagonists in DOAC-eligible patients. The major complication of anticoagulation is serious or life-threatening haemorrhage, which may necessitate prompt haemostatic intervention. Reversal of DOACs may also be required for patients in need of urgent invasive procedures. This guideline from the European Society of Anaesthesiology and Intensive Care (ESAIC) aims to provide evidence-based recommendations and suggestions on how to manage patients on DOACs undergoing urgent or emergency procedures including the treatment of DOAC-induced bleeding. A systematic literature search was performed, examining four drug comparators (dabigatran, rivaroxaban, apixaban, edoxaban) and clinical scenarios ranging from planned to emergency surgery with the outcomes of mortality, haematoma growth and thromboembolic complications. The GRADE (Grading of Recommendations, Assessment, Development and Evaluation) methodology was used to assess the methodological quality of the included studies. Consensus on the wording of the recommendations was achieved by a Delphi process. So far, no results from prospective randomised trials comparing two active comparators (e.g. a direct reversal agent and an unspecific haemostatic agent such as prothrombin complex concentrate: PCC) have been published yet and the majority of publications were uncontrolled and observational studies. Thus, the certainty of evidence was assessed to be either low or very low (GRADE C). Thirty-five recommendations and clinical practice statements were developed. During the Delphi process, strong consensus (>90% agreement) was achieved in 97.1% of recommendations and consensus (75 to 90% agreement) in 2.9%. DOAC-specific coagulation monitoring may help in patients at risk for elevated DOAC levels, whereas global coagulation tests are not recommended to exclude clinically relevant DOAC levels. In urgent clinical situations, haemostatic treatment using either the direct reversal or nonspecific haemostatic agents should be started without waiting for DOAC level monitoring. DOAC levels above 50 ng ml-1 may be considered clinically relevant necessitating haemostatic treatment before urgent or emergency procedures. Before cardiac surgery under activated factor Xa (FXa) inhibitors, the use of andexanet alfa is not recommended because of inhibition of unfractionated heparin, which is needed for extracorporeal circulation. In the situation of DOAC overdose without bleeding, no haemostatic intervention is suggested, instead measures to eliminate the DOACs should be taken. Due to the lack of published results from comparative prospective, randomised studies, the superiority of reversal treatment strategy vs. a nonspecific haemostatic treatment is unclear for most urgent and emergency procedures and bleeding. Due to the paucity of clinical data, no recommendations for the use of recombinant activated factor VII as a nonspecific haemostatic agent can be given. In the clinical scenarios of DOAC intake before urgent procedures and DOAC-induced bleeding, practitioners should evaluate the risk of bleeding of the procedure and the severity of the DOAC-induced bleeding before initiating treatment. Optimal reversal strategy remains to be determined in future trials for most clinical settings.

European Society of Anaesthesiology and Intensive Care consensus document on sustainability: 4 scopes to achieve a more sustainable practice.

Climate change is a defining issue for our generation. The carbon footprint of clinical practice accounts for 4.7% of European greenhouse gas emissions, with the European Union ranking as the third largest contributor to the global healthcare industry's carbon footprint, after the United States and China. Recognising the importance of urgent action, the European Society of Anaesthesiology and Intensive Care (ESAIC) adopted the Glasgow Declaration on Environmental Sustainability in June 2023. Building on this initiative, the ESAIC Sustainability Committee now presents a consensus document in perioperative sustainability. Acknowledging wider dimensions of sustainability, beyond the environmental one, the document recognizes healthcare professionals as cornerstones for sustainable care, and puts forward recommendations in four main areas: direct emissions, energy, supply chain and waste management, and psychological and self-care of healthcare professionals. Given the urgent need to cut global carbon emissions, and the scarcity of evidence-based literature on perioperative sustainability, our methodology is based on expert opinion recommendations. A total of 90 recommendations were drafted by 13 sustainability experts in anaesthesia in March 2023, then validated by 36 experts from 24 different countries in a two-step Delphi validation process in May and June 2023. To accommodate different possibilities for action in high- versus middle-income countries, an 80% agreement threshold was set to ease implementation of the recommendations Europe-wide. All recommendations surpassed the 80% agreement threshold in the first Delphi round, and 88 recommendations achieved an agreement >90% in the second round. Recommendations include the use of very low fresh gas flow, choice of anaesthetic drug, energy and water preserving measures, "5R" policies including choice of plastics and their disposal, and recommendations to keep a healthy work environment or on the importance of fatigue in clinical practice. Executive summaries of recommendations in areas 1, 2 and 3 are available as cognitive aids that can be made available for quick reference in the operating room.

EEG-Messung in Narkose

Based on the existing literature, the application of designated, processed EEG-monitors to measure anesthetic depth and the associated clinical implications are explained. EEG-monitors quantify the hypnotic portion of anesthesia, but not the nociceptive properties of anesthetics. Depth of anesthesia monitoring is common practice in many German hospitals and helps to visualize the interindividual variability of anesthetics, especially of propofol. Although deep anesthesia is associated with increased long-term mortality, this relation seems not to be causally related. Nevertheless, depth of anesthesia monitors help to identify patients being especially susceptible to anesthetics. Moreover, they have shown to reduce the incidence of intraoperative awareness and postoperative delirium. The application of processed EEG-monitors to reduce the incidence of postoperative delirium is currently recommended by the European Society of Anaesthesiology and Intensive Care.

Evaluation of the 'Sip Til Send' regimen before elective caesarean delivery using bedside gastric ultrasound: A paired cohort pragmatic study.

Pre-operative fasting is routinely advocated to avoid pulmonary aspiration. The European Society of Anaesthesiology and Intensive Care (ESAIC) recommends a fasting period of 2 h for liquids before surgery. Liberal drinking policies such as the 'Sip Til Send' are a suggested alternative to maintain hydration before surgery. To compare residual gastric volumes in fully fasted nonlabouring parturients before elective caesarean delivery with the 'Sip Til Send' with water liberal drinking protocol. Our hypothesis was the 'Sip Til Send' would be noninferior to standard fasting at minimising the residual gastric volume immediately before surgery. A paired cohort prospective observational pragmatic study using gastric ultrasound, analysed by an operator blinded to the fasting status of each scan. A tertiary maternity hospital in Dublin, Ireland. The study was conducted between January and June 2023. Pregnant women about to undergo elective caesarean delivery who had followed ESAIC fasting guidelines before admission. Each participant underwent two pairs (semi-recumbent and the semi-recumbent right lateral positions) of standardised ultrasound examinations of the gastric antrum: the order of these scans was randomised. The first pair of scans occurred on admission before the 'Sip Til Send' protocol commenced, the other pair just before spinal anaesthesia for caesarean delivery, after a variable time following the 'Sip Til Send' protocol. The primary outcome was the difference in antral cross-sectional area (CSA) between the fully fasted women on admission and the same women after following the 'Sip Til Send' protocol until just before spinal anaesthesia. Fifty-eight women were randomised for the study: 55 and 54 scans in the semi-recumbent position on admission, and 55 and 54 scans in the right lateral position just before spinal anaesthesia. The mean differences (95% CI) in CSA in the semi-recumbent and RL positions were 0.07 (-0.39 to 0.53) cm 2 and 0.04 (-0.60 to 0.68) cm 2 , respectively. Since the of 95% CIs did not cross the predefined noninferiority margin of 0.88 cm 2 , 'Sip Til Send' was noninferior to fully fasting in in terms of the antral CSA. The 'Sip Til Send' protocol of liberal hydration with water was noninferior to standard fasting prior to elective caesarean delivery. NCT05783427 ClinicalTrials.gov.

Peri-operative night-time work of anaesthesiologists: A qualitative study of critical issues and proposals.

Qualitative data on the opinions of anaesthesiologists regarding the impact of peri-operative night-time working conditions on patient safety are lacking. This study aimed to achieve in-depth understanding of anaesthesiologists' perceptions regarding the impact of night-time working conditions on peri-operative patient safety and actions that may be undertaken to mitigate perceived risks. Qualitative analysis of responses to two open-ended questions. Online platform questionnaire promoted by the European Society of Anaesthesiology and Intensive Care (ESAIC). The survey sample consisted of an international cohort of anaesthesiologists. We identified and classified recurrent themes in the responses to questions addressing perceptions regarding (Q1) peri-operative night-time working conditions, which may affect patient safety and (Q2) potential solutions. We analysed 2112 and 2113 responses to Q1 and Q2, respectively. The most frequently reported themes in relation to Q1 were a perceived reduction in professional performance accompanied by concerns regarding the possible consequences of work with fatigue (27%), and poor working conditions at night-time (35%). The most frequently proposed solutions in response to Q2 were a reduction of working hours and avoidance of 24-h shifts (21%), an increase in human resources (14%) and performance of only urgent or emergency surgeries at night (14%). Overall, the surveyed anaesthesiologists believe that workload-to-staff imbalance and excessive working hours were potential bases for increased peri-operative risk for their patients, partly because of fatigue-related medical errors during night-time work. The performance of nonemergency elective surgical cases at night and lack of facilities were among the reported issues and potential targets for improvement measures. Further studies should investigate whether countermeasures can improve patient safety as well as the quality of life of anaesthesia professionals. Regulations to improve homogeneity, safety, and quality of anaesthesia practice at night seem to be urgently needed.

An Audit on the Pre-operative Fasting Time of Trauma-List Orthopaedic Patients at a District General Hospital in Chichester, United Kingdom.

Pre-operative fasting of patients awaiting non-emergency surgeries has been a common practice to minimise the risk of vomiting and aspiration at the time of induction of anaesthesia. Current standard guidelines recommend that this fasting time be limited to two hours for clear fluids and six hours for solids and semi-solids, as prolonged fasting has been shown to be harmful to the patient. A descriptive cross-sectional study of the fasting times of all adult trauma orthopaedic patients who were operated on under anaesthesia between June 1 and 30,2023. Fifty patients who met the inclusion criteria were included in the study. The minimum and maximum fasting times observed for solids and semi-solids were 9 and 24 hours, respectively. The mean fasting time for solids and semi-solids was 15.8 hours. The minimum and maximum fasting times observed for clear fluids were 2 and 20 hours, respectively. The mean fasting time for clear fluids was 10.5 hours. Elderly patients accounted for a significant portion of the patients, with 64% (n=32) being above the age of 70 years. A significant disparity was noted between the current fasting practices and the recommended standards set out by the Royal College of Nursing, the Association of Anaesthetists of Great Britain and Ireland, the European Society of Anaesthesiology, and the American Society of Anaesthesiologists. The knowledge of pre-operative fasting among the orthopaedic team doctors and the ward nursing staff was found to be inadequate.

Assessing the educational value and content of YouTube videos for ultrasound-guided subclavian vein catheterization.

The European Society of Anaesthesiology (ESA) published a guideline regarding continuous ultrasound guidance for central venous catheters in 2020. YouTube has been a popular educational platform since its inception. The purpose of the present study was to evaluate the adequacy of videos on ultrasound-guided subclavian vein catheterization posted on YouTube based on this guideline. YouTube was scanned using the keywords associated with ultrasound-guided subclavian vein catheterization and 46 of the 106 most-watched videos were included in the study. The videos were divided into three groups, as individual, manufacturer, and academic according to their sources, and were evaluated as poor, satisfactory, and good in terms of the overall content. The videos were then evaluated based on ESA's six-title guide for more specific informational content. A total of 46 videos were reviewed and 52.2% (n = 24) were found to be prepared by individuals. Among the videos, the rate of videos describing only venipuncture (poor) was 23.9% (n = 11), 73.9% (n = 34) of videos described the verification of the guidewire location with venipuncture, and 2.2% of videos described all the recommendations suggested by the guide (n = 1). At the end of the catheterization procedure, 4.3% (n = 2) stated that the catheter location should be confirmed by using ultrasound, 15.2% (n = 7) recommended chest-X-ray, and 80.4% (n = 37) did not suggest any. Manufacturer and academic videos can be watched due to their high-quality scores, but it may be practical to prepare training videos with guidelines both for educators and students to have global access to the renewed guideline information.

Expectations of Anesthesiology and Intensive Care Professionals Toward Artificial Intelligence: Observational Study.

Artificial intelligence (AI) applications offer numerous opportunities to improve health care. To be used in the intensive care unit, AI must meet the needs of staff, and potential barriers must be addressed through joint action by all stakeholders. It is thus critical to assess the needs and concerns of anesthesiologists and intensive care physicians related to AI in health care throughout Europe. This Europe-wide, cross-sectional observational study investigates how potential users of AI systems in anesthesiology and intensive care assess the opportunities and risks of the new technology. The web-based questionnaire was based on the established analytic model of acceptance of innovations by Rogers to record 5 stages of innovation acceptance. The questionnaire was sent twice in 2 months (March 11, 2021, and November 5, 2021) through the European Society of Anaesthesiology and Intensive Care (ESAIC) member email distribution list. A total of 9294 ESAIC members were reached, of whom 728 filled out the questionnaire (response rate 728/9294, 8%). Due to missing data, 27 questionnaires were excluded. The analyses were conducted with 701 participants. A total of 701 questionnaires (female: n=299, 42%) were analyzed. Overall, 265 (37.8%) of the participants have been in contact with AI and evaluated the benefits of this technology higher (mean 3.22, SD 0.39) than participants who stated no previous contact (mean 3.01, SD 0.48). Physicians see the most benefits of AI application in early warning systems (335/701, 48% strongly agreed, and 358/701, 51% agreed). Major potential disadvantages were technical problems (236/701, 34% strongly agreed, and 410/701, 58% agreed) and handling difficulties (126/701, 18% strongly agreed, and 462/701, 66% agreed), both of which could be addressed by Europe-wide digitalization and education. In addition, the lack of a secure legal basis for the research and use of medical AI in the European Union leads doctors to expect problems with legal liability (186/701, 27% strongly agreed, and 374/701, 53% agreed) and data protection (148/701, 21% strongly agreed, and 343/701, 49% agreed). Anesthesiologists and intensive care personnel are open to AI applications in their professional field and expect numerous benefits for staff and patients. Regional differences in the digitalization of the private sector are not reflected in the acceptance of AI among health care professionals. Physicians anticipate technical difficulties and lack a stable legal basis for the use of AI. Training for medical staff could increase the benefits of AI in professional medicine. Therefore, we suggest that the development and implementation of AI in health care require a solid technical, legal, and ethical basis, as well as adequate education and training of users.
