Abstract
Background App-linked real-time feedback-devices for cardiopulmonary resuscitation (CPR) aim to improve laypersons' resuscitation quality. Resuscitation guidelines recommend these technologies in training settings. This is the first study comparing resuscitation quality of all App-linked feedback-devices currently on market. Methods A prospective randomised simulation study was performed. After standardised instructions, participants performed 2-minutes compression-only CPR on a manikin without feedback (baseline). Afterwards, participants performed 4 × 2 min CPR with four different feedback devices in randomised order (CorPatch® Trainer, CPRBAND AIO Training, SimCPR®ProTrainer, Relay Response™) (intervention). CPR metrics (chest compression depth (CD), chest compression rate (CR), percentage of correct CD/CR (%), correct hand position, correct chest recoil, and technical preparation-time) were assessed. Devices data were compared to the baseline group using Wilcoxon testing with IBM SPSS (primary outcome). Differences between devices were analysed with ANOVA testing (secondary outcome). Normally distributed data were described as mean ± standard deviation (SD) and non-normally distributed data as Median [Interquartile range (IQR). CPR self-confidence was measured by means of questionnaire before and after feedback devices' use. Comparison was performed by students t-test. Results Forty participants were involved. SimCPR®ProTrainer was the only device, which resulted in guideline-compliant chest compressions (Mean ± SD:5.37 ± 0.76) with improved chest compression depth (p < 0.001), and percentage of correct chest compression depth (p < 0.001) compared to unassisted CPR (baseline). CorPatch® Trainer as the only device with audio-visual recoil instructions resulted in improved chest recoil (Mean ± SD:72.25 ± 24.89) compared to baseline (Mean ± SD:49.00 ± 42.20; p < 0.01), while the other three devices resulted in significantly lower chest recoil rates (CPRBAND AIO Training: 37.03 ± 39.90; p < 0.01, SimCPR®ProTrainer: Mean ± SD:39.88 ± 36.50; p = 0.03, Relay Response™: Mean ± SD:36.88 ± 37.73; p = 0.02). CPR quality when using the different feedback devices differ in chest compression depth (p = 0.02), chest compression rate (p < 0.001), percentage of correct chest compression depth/rate (p = 0.03/p = 0.04), and technical preparation-time (p < 0.001). Feedback-devices' use increased participant's CPR self-confidence (p < 0.001). Conclusion Although, CPR feedback devices show improved CPR performance in layperson in some metrics, none of the tested CPR feedback devices supported layperson in overall adequate CPR performance. More and better technical functionality is necessary, to fully utilise the potential of CPR feedback devices and to prevent a worsening of CPR performance when layperson use this technology.

Abstract
Background and Objectives: Enucleation of an eye is the most invasive procedure in ophthalmologic surgery. It can be the result of various diseases (malignant/chronic/trauma/infection) and is nevertheless relatively rare, but leads to the loss of a strongly innervated neuronal organ. This study systematically evaluates postoperative pain levels following enucleation of the eye globe. Materials and Methods: This prospective single-center study enrolled twenty-four patients undergoing enucleation of the eye globe. Perioperatively all patients completed (preoperative day, day of surgery, 1st, 2nd, and 3rd day following surgery) standardized questionnaires concerning their pain experience and treatment-related side-effects (internal protocol, QUIPS, painDETECT®). Patients received usual pain therapy in an unstandardized individual manner. Results: Preoperatively, mean average pain intensity of all included patients was 3.29 ± 2.46 (range, 0-8), 3.29 ± 3.24 (range, 0-8) on the day of surgery, 4.67 ± 1.90 (range, 2-10) on day 1, 3.25 ± 1.39 (range, 1-6) on day 2, and 2.71 ± 1.30 (range, 1-6) on day 3 after surgery. Mean maximum pain intensity was 4.71 ± 3.28 (range, 0-10) preoperatively, 4.04 ± 3.78 (range, 0-10) on the day of surgery, 5.75 ± 2.01 (range, 2-10) on day 1, 4.25 ± 1.89 (range, 2-10) on day 2, and 3.88 ± 1.54 (range, 2-8) on day 3 after surgery. Nineteen patients (79.2%) stated that they would have preferred more pain therapy. Conclusions: Patients undergoing eye enucleation report pain sensations in need of intervention in this university hospital. Thus, effective standardized pain treatment concepts are now a high priority to be established in an interdisciplinary manner containing standardized regimens and continuous regional procedures. Awareness of this problem in the medical team should be sharpened through targeted training and information.

Abstract
BACKGROUND AND OBJECTIVE Despite a measurable increase in recent years, the bystander resuscitation rate in Germany lags behind the European comparison. Special centers for the care of patients after cardiac arrest, so-called cardiac arrest centers (CAC), have been established. The aim of this work is to evaluate the role of CACs, in addition to in-hospital patient care, in improving the bystander resuscitation rate in Germany and what obstacles exist in the implementation of resuscitation training. MATERIALS AND METHODS Online survey by the working group cardiopulmonary resuscitation (AG42) of the German Society of Cardiology (DGK) and the German Resuscitation Council (GRC) RESULTS: Of the 74 participating clinics (78.4% certified as CAC), 23 (31.1%) conduct lay resuscitation training. These mainly take place within the framework of action days for resuscitation (82.6%) or in schools (39.1%). Permanent cooperation with at least one school existed in 52.2%. Basic life support (BLS) resuscitation dummies are available in 63.5% of these clinics and an automated external defibrillator (AED) demonstration device in 43.2%. According to the interviewees, the biggest obstacles to the consistent implementation of resuscitation courses in schools include lack of qualified instructors, lack of refinancing and difficulties with regard to coordinating activities between schools and providers. CONCLUSIONS Direct training of lay rescuers by hospitals faces several obstacles. To increase the bystander resuscitation rate, focusing on targeted training of teachers as multipliers (train-the-trainer) can be a good approach for cardiac arrest centers.

Abstract
OBJECTIVES Left ventricular (LV) diastolic function strongly predicts outcomes after cardiac surgery, but there is no consensus about appropriate intraoperative assessment. Recently, intraoperative diastolic strain-based measurements assessed by transesophageal echocardiography (TEE) have shown a strong correlation with LV relaxation, compliance, and filling, but there are no reports about evaluation through the entire perioperative period. Therefore, the authors describe the intraoperative course of this novel assessment technique in patients who underwent coronary artery bypass grafting, and compare it with conventional echocardiographic measures and common grading algorithms of LV diastolic dysfunction (LVDD). DESIGN Prospectively obtained data. SETTING A single university hospital. PARTICIPANTS Thirty adult patients scheduled for isolated on-pump coronary artery bypass grafting surgery with preoperative preserved left and right ventricular systolic function, without significant heart valve disease and pulmonary hypertension, and an uneventful intraoperative course were included. INTERVENTIONS Transesophageal echocardiography was performed after induction of anesthesia (T1), after termination of cardiopulmonary bypass (T2), and after sternal closure (T3). Echocardiographic evaluation was performed in stable hemodynamic conditions, in sinus rhythm or atrial pacing, and vasopressor support with norepinephrine ≤0.1 µg/kg/min. MEASUREMENTS AND MAIN RESULTS Strain-based measurements of peak longitudinal strain rate during isovolumetric relaxation (SR-IVR) and during early (SR-E) and late (SR-A) LV filling were assessed using EchoPAC v204 software (GE Vingmed Ultrasound AS, Norway). Evaluation of conventional echocardiographic parameters included transmitral Doppler measures of early (E) and late (A) LV filling, as well as lateral-tissue Doppler velocity assessed during early (e´) and late (a´) LV filling, tricuspid regurgitation, and left atrial dilatation. Evaluation and grading of LV diastolic function by myocardial strain was feasible in all included patients at all time points of assessment. Using conventional grading algorithms, however, a substantial number of patients could not be sufficiently graded, falling into an indeterminate zone and not reliably estimating LVDD (T1, 40%; T2, 33%; T3, 36%). There was significant impairment of LV diastolic function after bypass, as measured by SR-IVR (T1 v T2, 0.28 s-1 [IQR 0.23; 0.31) v 0.18 s-1 [IQR 0.14; 0.22]; p < 0.001), SR-E (T1 v T2, 0.95 ± 0.34 s-1v 1.28 ± 0.36 s-1; p < 0.001), and E/SR-IVR (T1 v T2, 2.3 ± 1.0 m v 4.5 ± 2.1 m; p < 0.001]. Conventional echocardiographic measures remained unchanged during the same period (E/A T1 v T2, 1.27 [IQR 0.94; 1.59] v 1.21 [IQR 1.03; 1.47] [p = 1] and E/e´ T1 v T2, 7.0 [IQR 5.3; 9.6] v 6.35 [IQR 5.7; 9.9] [p = 0.9]). There were no significant changes in the values of SR-IVR, SR-E, SR-A, E/SR-IVR, E/A, and E/e´ before and after sternal closure (T2 v T3). CONCLUSION Intraoperative assessment of strain-based measurements of LV diastolic function and strain-based LVDD grading was feasible in this group of selected patients, whereas conventional parameters failed to describe LVDD sufficiently in a substantial number of patients. Diastolic strain-based measurements showed impairment of LV relaxation and compliance after bypass, which was not detected by conventional echocardiographic parameters. Therefore, diastolic myocardial strain analysis might be more sensitive in detecting myocardial diastolic dysfunction by TEE in the perioperative setting, with its dynamic changes of loading conditions, and might provide valuable and additional information on the perioperative changes of LV diastolic function.

Abstract
Sudden cardiac arrest is a global problem and is considered the third leading cause of death in industrialized countries. Patient survival rates after out-of-hospital cardiac arrest (OHCA) vary significantly between countries and continents. In particular, the 2021 European Resuscitation Council (ERC) Resuscitation Guidelines place a special focus on the chain of survival of patients after OHCA. As a complex, interconnected approach, the focus is on: Raising awareness for cardiac arrest and lay resuscitation, school children's education in resuscitation "KIDS SAVE LIVES", first responder systems - technologies to engage the community, telephone-assisted resuscitation (telephone-CPR; T-CPR) by dispatchers, and cardiac arrest centers (CAC) for further treatment in specialized hospitals. The Systems Saving Lives approach is a comprehensive strategy that emphasizes the interconnectedness of all links in the chain of survival following an OHCA, with a particular focus on the relationship between the community and emergency medical services (EMS). This system-level approach emphasizes the importance of the connection between all those involved in the chain of survival. It has a high potential to improve overall survival after OHCA. Therefore, it is recommended that these strategies be promoted and expanded in all countries.

Abstract
Background: Individual implementation rate of bronchoscopy-guided percutaneous dilatational tracheostomy (PDT) varies among intensivists. Simulation training (ST) can increase the safety of medical procedures by reducing stress levels of the performing team. The aim of this study was to evaluate the benefit of ST in PDT regarding procedural time, quality of performance, and percepted feelings of safety of the proceduralist and to compare conventional simulators (CSIM) with simulators generated from 3D printers (3DSIM). Methods: We conducted a prospective, single-center, randomized, blinded cross-over study comparing the benefit of CSIM versus 3DSIM for ST of PDT. Participants underwent a standardized theoretical training and were randomized to ST with CSIM (group A) or 3DSIM (group B). After ST, participants' performance was assessed by two blinded examiners on a porcine trachea regarding time required for successful completion of PDT and correct performance (assessed by a performance score). Percepted feelings of safety were assessed before and after ST. This was followed by a second training and second assessment of the same aspects with crossed groups. Results: 44 participants were included: 24 initially trained with CSIM (group A) and 20 with 3DSIM (group B). Correctness of the PDT performance increased significantly in group B (p < .01) and not significantly in group A (p = .14). Mean procedural time required for performing a PDT after their second ST compared to the first assessment (p < .01) was lower with no difference between group A and group B and irrespective of the participants' previous experience regarding PDT, age, and sex. Moreover, percepted feelings of safety increased after the first ST in both groups (p < .001). Conclusions: ST can improve procedural skills, procedural time, and percepted feelings of safety of the proceduralist in simulated PDT.

Abstract
Standardized reporting of data is crucial for out-of-hospital cardiac arrest (OHCA) research. While the implementation of first responder systems dispatching volunteers to OHCA is encouraged, there is currently no uniform reporting standard for describing these systems. A steering committee established a literature search to identify experts in smartphone alerting systems. These international experts were invited to a conference held in Hinterzarten, Germany, with 40 researchers from 13 countries in attendance. Prior to the conference, participants submitted proposals for parameters to be included in the reporting standard. The conference comprised five workshops covering different aspects of smartphone alerting systems. Proposed parameters were discussed, clarified, and consensus was achieved using the Nominal Group Technique. Participants voted in a modified Delphi approach on including each category as a core or supplementary element in the reporting standard. Results were presented, and a writing group developed definitions for all categories and items, which were sent to participants for revision and final voting using LimeSurvey web-based software. The resulting reporting standard consists of 68 core items and 21 supplementary items grouped into five topics (first responder system, first responder network, technology/algorithm/strategies, reporting data, and automated external defibrillators (AED)). This proposed reporting standard generated by an expert opinion group fills the gap in describing first responder systems. Its adoption in future research will facilitate comparison of systems and research outcomes, enhancing the transfer of scientific findings to clinical practice.

Abstract
The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Abstract
Bloodstream infection (BSI), a frequent cause of severe sepsis, is a life-threatening complication in critically ill patients and still associated with a high mortality rate. Rapid pathogen identification from blood is crucial for an early diagnosis and the treatment of patients with suspected BSI. For this purpose, novel diagnostic tools on the base of genetic analysis have emerged for clinical application. The aim of this study was to assess the diagnostic value of additional next-generation sequencing (NGS) pathogen test for patients with suspected BSI in a surgical ICU and its potential impact on antimicrobial therapy. In this retrospective single-centre study, clinical data and results from blood culture (BC) and NGS pathogen diagnostics were analysed for ICU patients with suspected BSI. Consecutive changes in antimicrobial therapy and diagnostic procedures were evaluated. Results: 41 cases with simultaneous NGS and BC sampling were assessed. NGS showed a statistically non-significant higher positivity rate than BC (NGS: 58.5% (24/41 samples) vs. BC: 21.9% (9/41); p = 0.056). NGS detected eight different potentially relevant bacterial species, one fungus and six different viruses, whereas BC detected four different bacterial species and one fungus. NGS results affected antimicrobial treatment in 7.3% of cases. Conclusions: NGS-based diagnostics have the potential to offer a higher positivity rate than conventional culture-based methods in patients with suspected BSI. Regarding the high cost, their impact on anti-infective therapy is currently limited. Larger randomized prospective clinical multicentre studies are required to assess the clinical benefit of this novel diagnostic technology.

Abstract
BACKGROUND Dispatcher assistance can help to save lives during layperson cardiopulmonary resuscitation during cardiac arrest. The aim of this study was to investigate the influence of different camera positions on the evaluation of cardiopulmonary resuscitation performance during video-assisted cardiopulmonary resuscitation. METHODS For this randomized, controlled simulation trial, seven video sequences of cardiopulmonary resuscitation performance were recorded from three different camera positions: side, foot and head position. Video sequences showed either correct cardiopulmonary resuscitation performance or one of the six typical errors: low and high compression rate, superficial and increased compression depth, wrong hand position or incomplete release. Video sequences with different cardiopulmonary resuscitation performances and camera positions were randomly combined such that each evaluator was presented seven individual combinations of cardiopulmonary resuscitation and camera position and evaluated each cardiopulmonary resuscitation performance once. A total of 46 paramedics and 47 emergency physicians evaluated seven video sequences of cardiopulmonary resuscitation performance from different camera positions. The primary hypothesis was that there are differences in accuracy of correct assessment/error recognition depending on camera perspective. Generalized linear multi-level analyses assuming a binomial distribution and a logit link were employed to account for the dependency between each evaluator's seven ratings. RESULTS Of 651 video sequences, cardiopulmonary resuscitation performance was evaluable in 96.8% and correctly evaluated in 74.5% over all camera positions. Cardiopulmonary resuscitation performance was classified correctly from a side perspective in 81.3%, from a foot perspective in 68.8% and from a head perspective in 73.6%, revealing a significant difference in error recognition depending on the camera perspective (p = .01). Correct cardiopulmonary resuscitation was mistakenly evaluated to be false in 46.2% over all perspectives. CONCLUSIONS Participants were able to recognize significantly more mistakes when the camera was located on the opposite side of the cardiopulmonary resuscitation provider. Foot position should be avoided in order to enable the dispatcher the best possible view to evaluating cardiopulmonary resuscitation quality.

Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) remains a frequent medical emergency with low survival rates even after a return of spontaneous circulation (ROSC). Growing evidence supports formation of dedicated teams in scenarios like cardiogenic shock to improve prognosis. Thus, the European Resuscitation Council (ERC) recommended introduction of Cardiac Arrest Centers (CAC) in their 2015 guidelines. Here, we aimed to elucidate the effects of newly introduced CACs in Germany regarding survival rate and neurological outcome. METHODS A multicenter retrospective observational cohort study was performed at three university hospitals and outcomes after OHCA were compared before and after CAC accreditation. Primary outcomes were survival until discharge and favorable neurological status (CPC 1 or 2) at discharge. RESULTS In total 784 patients (368 before and 416 after CAC accreditation) were analyzed. Rates of immediate percutaneous coronary intervention (40 vs. 52%, p = 0.01) and implementation of extracorporeal CPR (8 vs. 13%, p < 0.05) increased after CAC accreditation. Likelihood of favorable neurological status at discharge was higher after CAC accreditation (71 vs. 87%, p < 0.01), whereas overall survival remained similar (35 vs. 35%, p > 0.99). CONCLUSION CAC accreditation is linked to higher rates of favorable neurological outcome and unchanged overall survival.

Abstract
The International Liaison Committee on Resuscitation engages in a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation and first aid science. Draft Consensus on Science With Treatment Recommendations are posted online throughout the year, and this annual summary provides more concise versions of the final Consensus on Science With Treatment Recommendations from all task forces for the year. Topics addressed by systematic reviews this year include resuscitation of cardiac arrest from drowning, extracorporeal cardiopulmonary resuscitation for adults and children, calcium during cardiac arrest, double sequential defibrillation, neuroprognostication after cardiac arrest for adults and children, maintaining normal temperature after preterm birth, heart rate monitoring methods for diagnostics in neonates, detection of exhaled carbon dioxide in neonates, family presence during resuscitation of adults, and a stepwise approach to resuscitation skills training. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, using Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces list priority knowledge gaps for further research. Additional topics are addressed with scoping reviews and evidence updates.

Abstract
PURPOSE OF REVIEW The latest resuscitation guidelines contain a new chapter, which focuses on systems improving care for patients with out-of-hospital cardiac arrest (OHCA). In this article, we describe recent developments regarding telephone cardiopulmonary resuscitation (CPR), first responder systems, cardiac arrest centers, and global campaigns. RECENT FINDINGS Telephone CPR has been implemented in many countries, and recent developments include artificial intelligence and video calls to improve dispatch assisted CPR. However, the degree of implementation is not yet satisfying. Smartphone alerting systems are effective in reducing the resuscitation-free interval, but many regions do not yet use this technology. Further improvements are needed to reduce response times. Cardiac arrest centers increase the survival chance after OHCA. Specific criteria need to be defined and professional societies should establish a certification process. Global campaigns are effective in reaching people around the world. However, we need to evaluate the effects of the campaigns. SUMMARY Telephone CPR, first responder systems, cardiac arrest centers, and global campaigns are highlighted in the recent resuscitation guidelines. However, the degree of implementation is not yet sufficient. We do not only need to implement these measures, but we should also aim to monitor the systems regarding their performance and further improve them.

Abstract
In Germany per year approximately 60,000 and in Austria 5,000 adult patients suffer from out-of-hospital cardiac arrest. Only 10-15% of these patients survive without neurological damage. For decades hypothermic temperature control has been a central component of post-resuscitation treatment, but is controversial due to recently published studies.

Abstract
Objective Given the lack of a unified tool for appraising the quality of educational resources for lay-rescuer delivery of adult basic life support (BLS), this study aimed to develop an appropriate evaluation checklist based on a consensus of international experts. Methods In a two-round Delphi study, participating experts completed questionnaires to rate each item of a predeveloped 72-item checklist indicating agreement that an item should be utilized to evaluate the conformance of an adult BLS educational resource with resuscitation guidelines. Consensus on item inclusion was defined as a rating of ≥7 points from ≥75% of experts. Experts were encouraged to add anonymous suggestions for modifying or adding new items. Results Of the 46 participants, 42 (91.3%) completed the first round (representatives of 25 countries with a median of 16 years of professional experience in resuscitation) and 40 (87.0%) completed the second round. Thirteen of 72 baseline items were excluded, 55 were included unchanged, four were included after modification, and four new items were added. The final checklist comprises 63 items under the subsections “safety” (one item), “recognition” (nine items), “call for help” (four items), “chest compressions” (12 items), “rescue breathing” (12 items), “defibrillation” (nine items), “continuation of CPR” (two items), “choking” (10 items) and “miscellaneous” (four items). Conclusions The produced checklist is a ready-to-use expert consensus–based tool for appraising the quality of educational content on lay-rescuer provision of adult BLS. The checklist gives content developers a tool to ensure educational resources comply with current resuscitation knowledge, and may serve as a component of a prospective standardized international framework for quality assurance in resuscitation education.

Abstract
PURPOSE OF REVIEW Recognition of cardiac arrest and initiation of cardiopulmonary resuscitation (CPR) can be learned and adequately replicated by schoolchildren. Regular instruction of schoolchildren in CPR is therefore a core element to increase low bystander CPR rates. Thereby, schoolchildren CPR training evolved as own scientific field within the last decade. Aim was to describe current evidence in terms of epidemiology, teaching approaches and political aspects. RECENT FINDINGS Schoolchildren demonstrate a high motivation to be trained in CPR. Teaching approaches that combine theoretical and practical learning sessions guarantee a sustainable learning effect. Schoolchildren can adequately perform chest compressions and mouth-to-mouth ventilation from the age of 12 years. Use of digital media is a highly promising teaching approach. CPR training conducted by teachers from the own school is effective and guarantees continuous development of CPR skills. Integration of schoolchildren CPR training into school curricula is the foundation for a sustainable increase of lay resuscitation rates in the population. Scientific and political promotion of schoolchildren CPR training is needed to sensitize the population and move bystander CPR in the social focus. SUMMARY While bystander CPR rates are low in Europe comprehensive establishment of schoolchildren CPR training may sustainably increase survival after cardiac arrest.

Abstract
INTRODUCTION Cardiac arrest in the operating room is a rare but potentially life-threatening event with mortality rates of more than 50%. Contributing factors are often known, and the event is recognised rapidly as patients are usually under full monitoring. This guideline covers the perioperative period and is complementary to the European Resuscitation Council guidelines. MATERIAL AND METHODS The European Society of Anaesthesiology and Intensive Care and the European Society for Trauma and Emergency Surgery jointly nominated a panel of experts to develop guidelines for the recognition, treatment, and prevention of cardiac arrest in the perioperative period. A literature search was conducted in MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials. All searches were restricted to publications from 1980 to 2019 inclusive and to the English, French, Italian and Spanish languages. The authors also contributed individual, independent literature searches. RESULTS This guideline contains background information and recommendation for the treatment of cardiac arrest in the operating room environment, and addresses controversial topics such as open chest cardiac massage, resuscitative endovascular balloon occlusion and resuscitative thoracotomy, pericardiocentesis, needle decompression, and thoracostomy. CONCLUSIONS Successful prevention and management of cardiac arrest during anaesthesia and surgery requires anticipation, early recognition, and a clear treatment plan. The ready availability of expert staff and equipment must also be taken into consideration. Success not only depends on medical knowledge, technical skills and a well-organised team using crew resource management, but also on an institutional safety culture embedded in everyday practice through continuous education, training, and multidisciplinary co-operation.

Abstract
OBJECTIVES Left ventricular (LV) longitudinal function is reduced after on-pump coronary artery bypass grafting (CABG), while global LV function often is preserved. There are only limited data on the underlying compensatory mechanism. Therefore, the authors aimed to describe intraoperative changes of LV contractile pattern by myocardial strain analysis. DESIGN A prospective observational study. SETTING At a single university hospital. PARTICIPANTS A total of 30 patients scheduled for isolated on-pump CABG with an uneventful intraoperative course and preoperative preserved LV and RV function, sinus rhythm, without more-than-mild heart valve disease, or elevated pulmonary pressure. INTERVENTIONS Transesophageal echocardiography was performed after induction of anesthesia (T1), after termination of cardiopulmonary bypass (T2), and after sternal closure (T3). Echocardiographic evaluation was performed under stable hemodynamics, in sinus rhythm or atrial pacing, and vasopressor support with norepinephrine ≤0.1 µg/kg/min. MEASUREMENTS AND MAIN RESULTS EchoPAC v204 software (GE Vingmed Ultrasound AS, Norway) was used for analysis of 2-dimensional (2D) and 3-dimensional (3D) LV ejection fraction (EF), LV global longitudinal strain (GLS), LV global circumferential strain (GCS), LV global radial strain (GRS), LV apical rotation (aRot), LV basal rotation (bRot), and LV twist. Strain analysis was feasible in all included patients after termination of cardiopulmonary bypass (T2). Although there were no significant differences in the values of conventional echocardiographic parameters during the intraoperative interval, GLS deteriorated significantly after CABG compared to pre-bypass assessment (T1 v T2, -13.4% ± 2.9 v -11.8% ± 2.9; p = 0.007). GCS improved significantly after surgery (T1 v T2, -19.4% (IQR -17.1% to -21.2%) v -22.8% (IQR -21.1% to -24.7%); p < 0.001) as well as aRot (T1 v T2, -9.7° (IQR -7.1° to -14.1°) v -14.5° (IQR -12.1° to -17.1°); p < 0.001), bRot (T1 v T2, 5.1° (IQR 3.8°-6.7°) v 7.2° (IQR 5.6°-8.2°); p = 0.02), and twist (T1 v T2, 15.8° (IQR 11.7°-19.4°) v 21.6° (IQR 19.2°-25.1°); p < 0.001), while GRS remained unchanged. There were no significant changes in the values of GLS, GCS, GRS, aRot, bRot, or twist, as well as in the values of 2D and 3D LV EF before and after sternal closure (T2 v T3). CONCLUSION Beyond evaluation of longitudinal LV strain, measurements of circumferential and radial strain, as well as LV rotation and twist mechanics, were feasible in the intraoperative course of this study. Reduction of longitudinal function after on-pump CABG was compensated intraoperatively by improvement of GCS and rotation in the authors' group of patients. Perioperative assessment of GCS, GRS, as well as rotation and twist, might provide deeper insight into perioperative changes of cardiac mechanics.

Abstract
INTRODUCTION Cardiac arrest in the operating room is a rare but potentially life-threatening event with mortality rates of more than 50%. Contributing factors are often known, and the event is recognised rapidly as patients are usually under full monitoring. This guideline covers the perioperative period and is complementary to the European Resuscitation Council (ERC) guidelines. MATERIAL AND METHODS The European Society of Anaesthesiology and Intensive Care and the European Society for Trauma and Emergency Surgery jointly nominated a panel of experts to develop guidelines for the recognition, treatment and prevention of cardiac arrest in the perioperative period. A literature search was conducted in MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials. All searches were restricted to publications from 1980 to 2019 inclusive and to the English, French, Italian and Spanish languages. The authors also contributed individual, independent literature searches. RESULTS This guideline contains background information and recommendation for the treatment of cardiac arrest in the operating room environment, and addresses controversial topics such as open chest cardiac massage (OCCM), resuscitative endovascular balloon occlusion (REBOA) and resuscitative thoracotomy, pericardiocentesis, needle decompression and thoracostomy. CONCLUSION Successful prevention and management of cardiac arrest during anaesthesia and surgery requires anticipation, early recognition and a clear treatment plan. The ready availability of expert staff and equipment must also be taken into consideration. Success not only depends on medical knowledge, technical skills and a well organised team using crew resource management but also on an institutional safety culture embedded in everyday practice through continuous education, training and multidisciplinary co-operation.

Abstract
BACKGROUND Patients undergoing corneal abrasion as part of Descemet membrane endothelial keratoplasty (DMEK) under general anesthesia suffer from early burning pain postoperatively. This pain appears to be poorly treatable with systemic analgesics. This study aims to evaluate postoperative pain management using topical lidocaine gel after DMEK with iatrogenic corneal abrasion. METHODS Retrospective analysis of 28 consecutive patients undergoing DMEK with corneal abrasion from October 19, 2021, to November 12, 2021, at a German university hospital. Patients during week 1 and 2 received peri-operative standard pain treatment (cohort S) and additional local lidocaine gel during week 3 and 4 immediately postoperatively (cohort L). RESULTS 13 patients were included in cohort S and 15 patients in cohort L. At awakening all patients (100%) in cohort S reported burning pain, and six of 15 patients (40%) in cohort L reported burning pain. Burning pain scores were significantly lower in cohort L (p < 0.001 at awakening, p < 0.001 at 10 min, p < 0.001 at 20 min, p < 0.001 at 30 min, p = 0.007 at 40 min after awakening, and p < 0.001 at leaving recovery room). No significant differences between cohort S and cohort L were detected concerning surgical outcome during 1-month-follow-up (p = 0.901 for best corrected visual acuity). CONCLUSION Patients undergoing DMEK with corneal abrasion suffer significant pain in the recovery room. A single dose of topic lidocaine gel reduces the early postoperative burning pain sufficiently and does not affect the surgical outcome.

Abstract
BACKGROUND Recently, a non-commercial oxygenation laryngoscope was able to maintain apneic oxygenation during simulated intubation efforts. Since that prototype was 3 mm wider than a standard Macintosh laryngoscope blade, the intubation performance of this device may differ from standard blades. A new prototype of an oxygenation laryngoscope was developed, consisting of a standard-size Macintosh blade and a fixed oxygen supply line to the side. Actually, it is unclear at which point of this blade the oxygen supply line should end to facilitate the best possible oxygen supply for apneic oxygenation. METHODS In this simulation study using a standardized human airway manikin, the efficacy of apneic oxygenation by oxygen insufflation using standard and modified Macintosh blades was compared: a standard Macintosh blade without oxygen supply line as control, one with an additional oxygen supply line ending proximal near the handle, one with the line ending at the middle of the blade, and one with the line ending near the tip. A preoxygenated test lung was connected to an oximeter with a flow rate of 200ml/min, simulating oxygen consumption of a male adult, and to the trachea of an anatomically correctly shaped airway manikin. Apneic oxygenation was performed and oxygen content was measured over a 20-minutes observation period. Experiments were repeated five times for each laryngoscope blade. RESULTS Oxygen percentage in the test lung dropped from 100 ± 0% at the start of the experiment to 53 ± 1.5% in the room air control group (p < 0.001 compared to all other groups), and to 74 ± 2.5% in the proximal oxygen line group, whereas oxygen percentage remained at 100% in both the medium and distal oxygen line groups (p = 1 between these groups; p < 0.001 between all other groups). CONCLUSIONS In this simulation study with a preoxygenated airway manikin, the use of a modified Macintosh laryngoscope blade with oxygen line attached at the tip or at the middle were able to maintain apneic oxygenation without measurable drop of oxygen content over 20 min. Proximal placement of the oxygen supply line still showed an advantage against room air, however it did not completely prevent room air from entering the airway. TRIAL REGISTRATION Not applicable.

Abstract
Background Intensive care units (ICU) are central facilities of medical care in hospitals world-wide and pose a significant financial burden on the health care system. Objectives To provide guidance and recommendations for the requirements of (infra)structure, personal, and organization of intensive care units. Design and setting Development of recommendations based on a systematic literature search and a formal consensus process from a group of multidisciplinary and multiprofessional specialists from the German Interdisciplinary Association of Intensive Care and Emergency Medicine (DIVI). The grading of the recommendation follows the report from an American College of Chest Physicians Task Force. Results The recommendations cover the fields of a 3-staged level of intensive care units, a 3-staged level of care with respect to severity of illness, qualitative and quantitative requirements of physicians and nurses as well as staffing with physiotherapists, pharmacists, psychologists, palliative medicine and other specialists, all adapted to the 3 levels of ICUs. Furthermore, proposals concerning the equipment and the construction of ICUs are supplied. Conclusion This document provides a detailed framework for organizing and planning the operation and construction/renovation of ICUs.

Abstract
A high resuscitation rate can lead to better overall survival after cardiac arrest. In Europe, various campaigns in the field of lay resuscitation are achieving up to a threefold increase in survival. As part of the new Systems Saving Lives (SSL) chapter, the European Resuscitation Council (ERC) guidelines recommend cardiac awareness campaigns to engage the broader community. It has been noted that countries with high survival rates after an out-of-hospital cardiac arrest (OHCA) start education in resuscitation techniques at school age. The ERC 2021 guidelines recommend that all schoolchildren should routinely receive CPR training each year. Since 2015, the KIDS SAVE LIVES statement recommended for two hours of instruction per year in all schools worldwide by age of 12. Cardiac awareness campaigns like World Restart a Heart Day (WRAH) are aimed to raise awareness about resuscitation and to train as many people as possible.

Abstract
BACKGROUND Basic life support education for schoolchildren has become a key initiative to increase bystander cardiopulmonary resuscitation rates. Our objective was to review the existing literature on teaching schoolchildren basic life support to identify the best practices to provide basic life support training in schoolchildren. METHODS After topics and subgroups were defined, a comprehensive literature search was conducted. Systematic reviews and controlled and uncontrolled prospective and retrospective studies containing data on students <20 years of age were included. RESULTS Schoolchildren are highly motivated to learn basic life support. The CHECK-CALL-COMPRESS algorithm is recommended for all schoolchildren. Regular training in basic life support regardless of age consolidates long-term skills. Young children from 4 years of age are able to assess the first links in the chain of survival. By 10 to 12 years of age, effective chest compression depths and ventilation volumes can be achieved on training manikins. A combination of theoretical and practical training is recommended. Schoolteachers serve as effective basic life support instructors. Schoolchildren also serve as multipliers by passing on basic life support skills to others. The use of age-appropriate social media tools for teaching is a promising approach for schoolchildren of all ages. CONCLUSIONS Schoolchildren basic life support training has the potential to educate whole generations to respond to cardiac arrest and to increase survival after out-of-hospital cardiac arrest. Comprehensive legislation, curricula, and scientific assessment are crucial to further develop the education of schoolchildren in basic life support.

Abstract
Quality of care (QoC) is a fundamental tenet of modern healthcare and has become an important assessment-tool for healthcare authorities, stakeholders and the public. However, QoC is difficult to measure and quantify because it is a multifactorial and multidimensional concept. Comparison of clinical institutions can be challenging when QoC is estimated solely based on clinical outcomes. Thus, measuring quality through quality indicators (QIs) can provide a foundation for quality assessment and has become widely used in this context. QIs for the evaluation of QoC in acute myocardial infarction are now well-established, but no such indicators exist for the process from resuscitation of cardiac arrest and post-resuscitation care in Europe. In this context, the Association of Acute Cardiovascular Care of the European Society Cardiology, the European Resuscitation Council, European Society of Intensive Care Medicine and the European Society for Emergency Medicine, have reflected on the measurement of QoC in cardiac arrest. A set of QIs have been proposed, with the scope to unify and evolve QoC for the management of cardiac arrest across Europe. We present here the list of QIs (6 primary QIs and 12 secondary Qis), with descriptions of the methodology used, scientific justification and motives for the choice for each measure with the aim that this set of QIs will enable assessment of the quality of post-out-of-hospital cardiac arrest management across Europe.

Abstract
OBJECTIVES Noninvasive echocardiographic analysis of left ventricular (LV) myocardial work (MW) enables insights into cardiac mechanics, contractility, and efficacy beyond ejection fraction (EF) and global longitudinal strain (GLS). However, there are limited perioperative data on patients undergoing coronary artery bypass graft (CABG) surgery. The authors aimed to describe the feasibility and the intraoperative course of this novel assessment tool of ventricular function in these patients, and compare it to conventional 2-dimensional (2D) and 3-dimensional (3D) echocardiographic parameters and strain analysis. DESIGN A prospective observational study. SETTING At a single university hospital. PARTICIPANTS Twenty-five patients with preoperative preserved LV and right ventricular function, sinus rhythm, without significant heart valve disease or pulmonary hypertension, and an uncomplicated intraoperative course scheduled for isolated on-pump CABG surgery. INTERVENTIONS Transesophageal echocardiography (TEE) was performed intraoperatively after the induction of anesthesia (T1), after termination of cardiopulmonary bypass (T2), and after sternal closure (T3). All measurements were performed under stable hemodynamic conditions, in sinus rhythm or atrial pacing, and vasopressor support with norepinephrine ≤ 0.1 µg/kg/min. MEASUREMENTS AND MAIN RESULTS The EchoPAC v204 software (GE Vingmed Ultrasound AS, Norway) was used for analysis of 2D and 3D LVEF, LV GLS, LV global work index (GWI), LV global constructive work (GCW), LV global wasted work (GWW), and LV global work efficiency (GWE). The MW analysis was feasible in all patients. Although there was no significant difference in the values of 2D and 3D EF during the intraoperative interval, GLS deteriorated significantly after CABG compared to assessment after induction of anesthesia (T1 v T2, -13.3 ± 3.0% v -11.6 ± 3.1%; p = 0.012). The GWI declined significantly after surgery (T1 v T2, 1,224 ± 312 mmHg% v 940 ± 267 mmHg%; p < 0.001), as well as GCW (T1 v T2, 1,460 ± 312 mmHg% v 1,244 ± 336 mmHg%; p = 0.005). The GWW increased after CABG (T1 v T2, 143 mmHg% (IQR 99-183) v 251 mmHg% (IQR 179-361); p < 0.001), and GWE decreased (T1 v T2, 89% (IQR 85-92) v 80% (IQR 75-87); p < 0.001). There were no significant changes in the values of 2D and 3D EF, GLS, GWI, GCW, GWW, and GWE before and after sternal closure (T2 v T3). CONCLUSION The intraoperative analysis of noninvasive echocardiographically-assessed LV MW indices is feasible. In the short-term period after uncomplicated on-pump CABG, GLS, as well as global and constructive MW, decreased, whereas wasted work increased, resulting in a less efficient left ventricle. None of these aspects was detected by conventional echocardiographic parameters. Therefore, strain and MW analysis might be more sensitive parameters in detecting myocardial dysfunction by TEE in the perioperative setting, adding information on perioperative cardiac energetics.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a global pandemic, required the donning of personal protective equipment during clinical contact, and continues to be a significant worldwide public health concern. Pediatric cardiac arrest is a rare but critical condition with a high mortality rate, the outcomes of which may be negatively affected by donning personal protective equipment. The aim of this study is to perform a systematic review and meta-analysis of the impact of the COVID-19 pandemic on pediatric cardiac arrest outcomes. We conducted a systematic review with meta-analysis in the following databases: PubMed, EMBASE, Scopus, Web of Science, and Cochrane Library from their inception to 1 October 2022. We included studies published in English on pediatric patients with cardiac arrest, dichotomized by the pre- and during-COVID-19 periods and then stratified by COVID-19 positive or negative status, to evaluate clinical outcomes associated with cardiac arrest. Six studies were included in the meta-analysis. In witnessed out-of-hospital cardiac arrest patients, there were no differences between the pandemic and pre-pandemic periods for witnessed cardiac arrest (28.5% vs. 28.7%; odds ratio (OR) = 0.99; 95% confidence interval (CI): 0.87 to 1.14; p = 0.93), administration of bystander cardiopulmonary resuscitation (61.5 vs. 63.6%; OR = 1.11; 95%CI: 0.98 to 1.26; p = 0.11), bystander automated external defibrillator use (both 2.8%; OR = 1.00; 95%CI: 0.69 to 1.45; p = 0.99), return of spontaneous circulation(8.4 vs. 8.9%; OR = 0.93; 95%CI: 0.47 to 1.88; p = 0.85), survival to hospital admission (9.0 vs. 10.2%, OR = 0.81; 95%CI: 0.45 to 1.44; p = 0.47), or survival to hospital discharge (13.4 vs. 12.4%; OR = 0.62; 95%CI: 0.22 to 1.72; p = 0.35). COVID-19 did not change pediatric cardiac arrest bystander interventions or outcomes.

Abstract
BACKGROUND The present meta-analysis of clinical and simulation trials aimed to compare video-instructed dispatcher-assisted bystander cardiopulmonary resuscitation (V-DACPR) with conventional audio-instructed dispatcher-assisted bystander cardiopulmonary resuscitation (C-DACPR). METHODS We searched PubMed, Embase, Web of Science, Cochrane Collaboration databases and Scopus from inception until June 10, 2021. The primary outcomes were the prehospital return of spontaneous circulation (ROSC), survival to hospital discharge, and survival to hospital discharge with a good neurological outcome for clinical trials, and chest compression quality for simulation trials. Odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) indicated the pooled effect. The analyses were performed with the RevMan 5.4 and STATA 14 software. RESULTS Overall, 2 clinical and 8 simulation trials were included in this meta-analysis. In clinical trials, C-DACPR and V-DACPR were characterised by, respectively, 11.8% vs. 24.3% of prehospital ROSC (OR = 0.46; 95% CI: 0.30, 0.69; I2 = 66%; p < .001), 10.7% vs. 22.3% of survival to hospital discharge (OR = 0.46; 95% CI: 0.30, 0.70; I2 = 69%; p < .001), and 6.3% vs. 16.0% of survival to hospital discharge with a good neurological outcome (OR = 0.39; 95% CI: 0.23, 0.67; I2 = 73%; p < .001). In simulation trials, chest compression rate per minute equalled 91.3 ± 22.6 for C-DACPR and 107.8 ± 12.6 for V-DACPR (MD = -13.40; 95% CI: -21.86, -4.95; I2 = 97%; p = .002). The respective values for chest compression depth were 38.7 ± 14.3 and 41.8 ± 12.5 mm (MD = -2.67; 95% CI: -8.35, 3.01; I2 = 98%; p = .36). CONCLUSIONS As compared with C-DACPR, V-DACPR significantly increased prehospital ROSC and survival to hospital discharge. Under simulated resuscitation conditions, V-DACPR exhibited a higher rate of adequate chest compressions than C-DACPR.Key messagesBystander cardiopulmonary resuscitation parameters significantly depend on the dispatcher's support and the manner of the support provided.Video-instructed dispatcher-assisted bystander cardiopulmonary resuscitation can increase the rate of prehospital return of spontaneous circulation and survival to hospital discharge.Video-instructed dispatcher-assisted bystander cardiopulmonary resuscitation improves the quality of chest compressions compared with dispatcher-assisted resuscitation without video instruction.

Abstract
Background: In a cannot-ventilate-cannot-intubate situation, careful preoxygenation with high FiO2 allowing subsequent apneic oxygenation can be life-saving. The best position for an oxygen supply line within the human airway at which oxygen insufflation is more effective than standard preoxygenation with a face mask is unknown. Methods: In this experimental study, we compared the effectiveness of preoxygenation by placing an oxygen cannula at the nose entrance, through the nose at the soft palatine, or at the base of the tongue; as a control we used ambient air. We connected a fully preoxygenated test lung on one side to an oximeter with a flow rate of 200 mL/min simulating the oxygen consumption of a normal adult on the other side of the trachea of an anatomically correctly shaped airway manikin over a 20 min observation period five times for each cannula placement in a random order. Results: The oxygen percentage in the test lung dropped from 100% in all groups to 53 ± 1% in the ambient air control group, to 87 ± 2% in the nasal cannula group, and to 96 ± 2% in the soft palatine group; it remained at 99 ± 1% in the base of the tongue group (p = 0.003 for the soft palatine vs. base of the tongue and p < 0.001 for all other groups). Conclusions: When simulating apneic oxygenation in a preoxygenated manikin, oxygen insufflation at the base of the tongue kept the oxygen percentage at baseline values of 99%, demonstrating a complete block of ambient air flowing into the airway of the manikin. Oxygen insufflation at the soft palatine or insufflation via a nasal cannula were less effective regarding this effect.

Abstract
Lay resuscitation is one of the most important measures to increase the survival rate of patients after out-of-hospital cardiac arrest. While European countries, and especially Scandinavian countries, achieve lay resuscitation rates of over 80%, the rate in Germany is only around 40%. The 2021 Resuscitation Guidelines updated by the European Resuscitation Council give special weight to Systems Saving Lives and focus on resuscitation by laypersons. The Systems Saving Lives emphasize the interplay between all actors involved in the chain of survival and thereby specify the link between the emergency service and the general population.Based on the BIG FIVE survival strategies after cardiac arrest, five key strategies are outlined that can achieve the greatest improvement in survival. These are (1) increasing lay resuscitation rates through campaigns and KIDS SAVE LIVES school-based resuscitation training, (2) implementing telephone resuscitation in dispatch centers, (3) first responder systems, (4) advanced life support, and (5) specialized cardiac arrest centers.

Abstract
The endothelial glycocalyx and endothelial surface layer are crucial for several functions of the vasculature. Damage to the glycocalyx (“shedding”) occurs during diverse clinical conditions, including major surgery. Mast cell tryptase has been proposed as one possible “sheddase”. During oncologic oral surgery, glycocalyx shedding could be detrimental due to loss of vascular barrier function and consequent oedema in the musculocutaneous flap graft. Concentrations of the glycocalyx components heparan sulphate and syndecan-1, as well as of tryptase in blood serum before and after surgery, were measured in 16 patients undergoing oncologic oral surgery. Secondary measures were the concentrations of these substances on postoperative days 1 and 2. Heparan sulphate rose from 692 (median, interquartile range: 535–845) to 810 (638–963) ng/mL during surgery. Syndecan-1 increased from 35 (22–77) ng/mL to 138 (71–192) ng/mL. Tryptase remained virtually unchanged with 4.2 (3–5.6) before and 4.2 (2.5–5.5) ng/mL after surgery. Concentrations of heparan sulphate and syndecan-1 in serum increased during surgery, indicating glycocalyx shedding. Tryptase concentration remained equal, suggesting other sheddases than systemic tryptase release to be responsible for damage to the glycocalyx. Investigating strategies to protect the glycocalyx during oncologic oral surgery might hold potential to improve flap viability and patient outcome.

Abstract
Purpose Aspiration is a feared complication that may occur during airway management, and can significantly contribute to morbidity and mortality. Availability of a suctioning device with a suction catheter capable of clearing the airway is mandatory for airway management. However, suction performance may be significantly different amongst different suction catheters. The aim of this study was to compare suction rates of a standard 14 Ch suction catheter (SC), a Yankauer catheter (Y) and a DuCanto catheter (DC) using 4 fluids with different viscosity. Methods In this simulation trial, 4 preparations with standardized viscosity were prepared using a Xanthane-based medical fluid thickener. Lowest viscosity was achieved using tap water without thickener, syrup-like viscosity was achieved by adding 10 g per liter tap water, honey-like viscosity was achieved by adding 20 g per liter, and a pudding-like viscosity was achieved by adding 30 g of thickening powder per liter tap water. Each preparation was suctioned for 15 s with the three different suctioning devices. Measurements were repeated four times. The amount of removed preparation by suctioning was measured using a tared scale. Results Suction rates for water were 580 ± 34 mg for SC, 888 ± 5 mg for Y and 1087 ± 15 for DC; for syrup-like viscosity it was 383 ± 34(SC) vs. 661 ± 64(Y) vs. 935 ± 42(DC); for honey-like viscosity it was 191 ± 21(SC) vs. 426 ± 34(Y) vs. 590 ± 68(DC); and for pudding-like viscosity 74 ± 13(SC) vs. 164 ± 6(Y) vs. 211 ± 8(DC). Conclusion Suctioning liquids of different viscosity, the new DuCanto catheter was more effective than the Yankauer catheter that was more effective than a standard suctioning catheter. The relative superiority of the DuCanto was highest in fluids with high viscosity.
