[PMID: 39004562 DOI: 10.1016/j.enfie.2024.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 02/25/2024] [Accepted: 04/03/2024] [Indexed: 07/16/2024]
Abstract
INTRODUCTION The installation of an arterial line is one of the invasive procedures performed for hemodynamic monitoring and, even with its clear importance in intensive care, it is still an invasive procedure and liable to cause harms to the patients. OBJECTIVE To identify the adverse events associated with the use of arterial catheters in critically-ill patients in the world scientific production. METHODOLOGY The present scoping review was conducted according to the JBI methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist was used for reporting. The research question was "Which adverse events related to the use of arterial catheters in patients admitted to intensive care are more evident in the literature?". Data collection took place in the following databases: LILACS; MEDLINE; EMBASE; CINAHL, EBSCOhost; and WEB OF SCIENCE. RESULTS Through the search strategies, 491 articles were found in the databases. After exclusion of duplicates, peer analysis of titles and abstracts, full reading and screening of lists of references, the final sample of studies included was 38 articles. The main harms cited by the publications were as follows: limb ischemia, thrombosis, hemorrhage, accidental removal, inadvertent connection of inadequate infusion solution, pseudoaneurysm and bloodstream infection. CONCLUSIONS It was evidenced that patients are subjected to risks of adverse events from the insertion moment to removal of the arterial catheter, focusing on the infusion solution used to fill the circuit, the type of securement and dressings chosen, as well as the Nursing care measures for the prevention of bloodstream infection.

Abstract
Intubation for mechanical ventilation (MV) is one of the most common high-risk procedures performed in Intensive Care Units (ICUs). Early prediction of intubation may have a positive impact by providing timely alerts to clinicians and consequently avoiding high-risk late intubations. In this work, we propose a new machine learning method to predict the time to intubation during the first five days of ICU admission, based on the concept of cure survival models. Our approach combines classification and survival analysis, to effectively accommodate the fraction of patients not at risk of intubation, and provide a better estimate of time to intubation, for patients at risk. We tested our approach and compared it to other predictive models on a dataset collected from a secondary care hospital (AZ Groeninge, Kortrijk, Belgium) from 2015 to 2021, consisting of 3425 ICU stays. Furthermore, we utilised SHAP for feature importance analysis, extracting key insights into the relative significance of variables such as vital signs, blood gases, and patient characteristics in predicting intubation in ICU settings. The results corroborate that our approach improves the prediction of time to intubation in critically ill patients, by using routinely collected data within the first hours of admission in the ICU. Early warning of the need for intubation may be used to help clinicians predict the risk of intubation and rank patients according to their expected time to intubation.

Abstract
BACKGROUND Airway management is a crucial skill for many clinicians. Besides mastering the technical skills of establishing a patent airway, human factors including leadership and team collaboration are essential. Teaching these human factors is often challenging for instructors who lack dedicated training. Therefore, the European Airway Management Society (EAMS) developed the Teach-the-Airway-Teacher (TAT) course. METHODS This online post-course survey of TAT-course participants 2013-2021 investigated the impact of the TAT-course and the status of airway management teaching in Europe. Twenty-eight questions e-mailed to participants (using SurveyMonkey) assessed the courses' strengths and possible improvements. It covered participants' and workplace details; after TAT-course considerations; and specifics of local airway teaching. Data were assessed using Excel and R. RESULTS Fifty-six percent (119/213) of TAT-participants answered the survey. Most were anaesthetists (84%), working in university level hospitals (76%). Seventy-five percent changed their airway teaching in some way, but 20% changed it entirely. The major identified limitation to airway teaching in their departments was "lack of dedicated resources" (63%), and the most important educational topic was "Teaching non-technical skills" (70%). "Lecturing " was considered less important (37%). Most surveyed anaesthesia departments lack a standardized airway teaching rotation. Twenty-one percent of TAT-participants rated their departmental level of airway teaching overall as inadequate. CONCLUSIONS This survey shows that the TAT-course purpose was successfully fulfilled, as most TAT-course participants changed their airway teaching approach and did obtain the EAMS-certificate. The feedback provided will guide future TAT-course improvements to advance and promote a comprehensive approach to teaching airway management.

Prevalence of peri-intubation major adverse events among critically ill patients: A systematic review and meta analysis. Am J Emerg Med 2023; 71:200-216. [PMID: 37437438 DOI: 10.1016/j.ajem.2023.06.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 05/25/2023] [Accepted: 06/26/2023] [Indexed: 07/14/2023] Open
Abstract
BACKGROUND Peri-intubation major adverse events (MAEs) are potentially preventable and associated with poor patient outcomes. Critically ill patients intubated in Emergency Departments, Intensive Care Units or medical wards are at particularly high risk for MAEs. Understanding the prevalence and risk factors for MAEs can help physicians anticipate and prepare for the physiologically difficult airway. METHODS We searched PubMed, Scopus, and Embase for prospective and retrospective observational studies and randomized control trials (RCTs) reporting peri-intubation MAEs in intubations occurring outside the operating room (OR) or post-anesthesia care unit (PACU). Our primary outcome was any peri-intubation MAE, defined as any hypoxia, hypotension/cardiovascular collapse, or cardiac arrest. Esophageal intubation and failure to achieve first-pass success were not considered MAEs. Secondary outcomes were prevalence of hypoxia, cardiac arrest, and cardiovascular collapse. We performed random-effects meta-analysis to identify the prevalence of each outcome and moderator analyses and meta-regressions to identify risk factors. We assessed studies' quality using the Cochrane Risk of Bias 2 tool and the Newcastle-Ottawa Scale. RESULTS We included 44 articles and 34,357 intubations. Peri-intubation MAEs were identified in 30.5% of intubations (95% CI 25-37%). MAEs were more common in the intensive care unit (ICU; 41%, 95% CI 33-49%) than the Emergency Department (ED; 17%, 95% CI 12-24%). Intubation for hemodynamic instability was associated with higher rates of MAEs, while intubation for airway protection was associated with lower rates of MAEs. Fifteen percent (15%, 95% CI 11.5-19%) of intubations were complicated by hypoxia, 2% (95% CI 1-3.5%) by cardiac arrest, and 18% (95% CI 13-23%) by cardiovascular collapse. CONCLUSIONS Almost one in three patients intubated outside the OR and PACU experience a peri-intubation MAE. Patients intubated in the ICU and those with pre-existing hemodynamic compromise are at highest risk. Resuscitation should be considered an integral part of all intubations, particularly in high-risk patients.

Abstract
Over recent years, High Flow Nasal Cannula (HFNC) oxygen therapy has been more and more extensively applied in numerous medical settings, and it is now carried out in invasive procedures such as pre-oxygenation before orotracheal intubation, often leading to complications. More generally, pre-oxygenation is aimed at maintaining the highest possible oxygen saturation for extended periods of time. With this in mind, HFNC seems as effective as standard oxygen delivery with regard to hematosis in patients with mild or moderate hypoxemia, and it presents the advantage of reducing the adverse events associated with intubation. That said, during pre-oxygenation of patients with severe hypoxemia, non-invasive ventilation (NIV) is probably more effective than HFNC, especially in the prevention of respiratory events. However, in patients with little or no hypoxemia undergoing risky procedures such as bronchial endoscopy, HFNC allows better oxygen saturation than standard methods. To summarize, even though NIV remains useful in unstable patients, especially in decreasing desaturation episodes, HFNC could represent a reasonable alternative in case of poor tolerance, allowing continuous oxygenation of patients requiring digestive endoscopy or trans-esophageal ultrasound.

Abstract
Tracheal intubation in the critically ill is associated with serious complications, mainly cardiovascular collapse and severe hypoxemia. In this narrative review, we present an update of interventions aiming to decrease these complications. MACOCHA is a simple score that helps to identify patients at risk of difficult intubation in the intensive care unit (ICU). Preoxygenation combining the use of inspiratory support and positive end-expiratory pressure should remain the standard method for preoxygenation of hypoxemic patients. Apneic oxygenation using high-flow nasal oxygen may be supplemented, to prevent further hypoxemia during tracheal intubation. Face mask ventilation after rapid sequence induction may also be used to prevent hypoxemia, in selected patients without high-risk of aspiration. Hemodynamic optimization and management are essential before, during and after the intubation procedure. All these elements can be integrated in a bundle. An airway management algorithm should be adopted in each ICU and adapted to the needs, situation and expertise of each operator. Videolaryngoscopes should be used by experienced operators.

Abstract
Our objective was to compare video-assisted laryngoscopy (VAL) with direct laryngoscopy (DL) for glottic visualization in a pediatric intensive care unit in terms of the success rate in first attempts. Our study included patients aged from 1 month to 18 years who were admitted to the pediatric intensive care unit. We excluded patients with limited neck extension (C-spine immobilization, congenital abnormality), congenital anomalies (e.g., Pierre Robin syndrome, micrognathia, macroglossia), and recent airway surgery. Patients were premedicated before intubation. The time to intubation was defined as the time between the start of anesthesia and completion of intubation. The start of anesthetic induction was defined as the time the sedative was first administered. Completion of intubation was defined as the time that the end-tidal carbon dioxide tension was detected. We evaluated 120 of 135 intubations that met our inclusion criteria; 15 were excluded because in eight cases (53%) non-pediatric intensive care physicians made the initial attempts, and in seven cases (47%) the recorded intubation times were erroneous. We detected significantly higher POGO scores in the VAL group (p<0.001). VAL provided a fuller view of the glottis (Cormack and Lehane grade 1) than DL (p<0.001). Although the intubation attempts in the DL group were significantly higher (two or more attempts), no intubation failures occurred in either group.

Abstract
The ability to perform invasive bedside procedures (IBPs) safely and efficiently is a core skill set within critical care medicine. Fellowship training provides a pivotal time for learners to attain baseline proficiency in such procedures to decrease patient complications. The coronavirus disease 2019 pandemic has posed distinct challenges to the traditional model of teaching and supervising IBPs in the intensive care unit, including stewardship of personal protective equipment and limiting health care worker exposure to persons with coronavirus disease 2019. To address these challenges, we piloted a novel method of IBP supervision and teaching using a virtual monitoring system. In this virtual procedural supervision model, the supervising teacher is located outside the patient room, limiting personal protective equipment use and health care worker exposure. An audiovisual monitoring system allowed communication between the teacher and the learner as well as supervisor visualization of the procedural encounter. Virtual supervision was used for central line placement and bronchoscopy in the medical intensive care unit with no complications or instances of the supervisor needing to enter the patient room. Success was felt to depend on camera positioning and preprocedure planning and to be best for advanced learners who would not require tactile feedback. Upper level learners appreciated autonomy granted by this process. Virtual IBP supervision is felt to be a useful tool in specific situations. As with any tool, there are notable strengths and limitations. Success is felt to be optimized when attention is paid to procedural teaching best practices, learner selection, and technological logistics.

Abstract
BACKGROUND Training in procedural skills is often suboptimal. The aim of this study was to quantify the needs of residents in internal medicine (IM), critical care (CC), and emergency medicine (EM) for instruction in ultrasound-guided procedures. METHODS All IM, EM and CC residents (n = 200) at King Abdulaziz Medical City, Riyadh, Saudi Arabia, were invited to participate in a questionnaire-based survey to identify skill and experience gaps. The contribution of procedural skills to patient care (i.e. applicability) and proficiency in the sterile technique required to perform ultrasound-guided procedures were rated on Likert scales. Data on training, accreditation, and experience with and without ultrasound were collected. RESULTS The overall response rate was 72% (IM 91%, CC 100%, EM 40%). Although the sample reported that procedural skills were very applicable, 19% (IM n = 25, EM n = 2) had not performed any procedures. However, five residents were accredited in point-of-care ultrasound, 61% of the sample had performed ultrasound-guided procedures and 65% had used landmark techniques. Whilst more internists had performed procedures using landmark techniques, CC and EM residents had performed more ultrasound-guided procedures. Whilst CC residents had not missed any opportunities to perform procedures because supervisors were less available, EM (6) and IM (89) residents had. Whilst skill gaps were only identified in the IM residency programme, experience gaps were present in all three residency programmes. The IM residency programme had larger experience gaps than the CC and EM programmes for all procedural skills. DISCUSSION Residents in IM, CC and EM perceive that ultrasound-guided procedures are relevant to their practice. However, the IM residents performed fewer procedures than CC residents and EM residents at least partly because internists also lack skills in ultrasound. Training in ultrasound-guided procedures may reduce the use of landmark techniques and improve patient safety. Residents in IM, CC and EM therefore require training in ultrasound-guided procedures.

Abstract
BACKGROUND Optimization of preoxygenation procedure can help to secure the method of intubation by reducing the risks of severe hypoxemia and other problems. There is confusion for efficacy of non-invasive ventilation compared to high-flow oxygen therapy regarding occurrence of severe hypoxemia during the intubation procedure. The purpose of the study was to compare the difference between noninvasive ventilation and high flow oxygen therapy to prevent desaturation during laryngoscopy. METHODS Patients underwent high-flow nasal cannula oxygen therapy (HCO cohort, n = 161) or non-invasive ventilation procedure (NIV cohort, n = 154) for oxygenation and ventilation due to acute hypoxemic respiratory failure in the intensive care unit. Data before preoxygenation, preoxygenation, intubation, laryngoscopy, and complications of patients due to tracheal intubation were retrospectively collected and analyzed. RESULTS There was no difference between both cohorts for the demographical and clinical conditions of the patients before preoxygenation (p > 0.05 for all parameters), numbers of patients with severe hypoxia during the intubation procedure (35 vs. 45, p = 0.303), the time duration of laryngoscopy (p = 0.847), number of laryngoscopies attempts (p = 0.804), and immediate and late complications during the intubation procedure. The values of pulse oximetry were reported higher for patients of NIV cohort than those of HCO cohort during preoxygenation. Fewer numbers of patients were reported with severe hypoxia among patients of the NIV cohort than those of the HCO cohort (24 vs., 40, p = 0.042) who have moderate-to-severe hypoxemia (partial pressure of arterial oxygen to fraction of inspired oxygen ratio ≤ 200 mmHg) before preoxygenation. The most common complications were hypertension, pulmonary aspiration, and increased 30-day mortality. CONCLUSIONS When compared, there was no difference between non-invasive ventilation technique and high-flow oxygen therapy to minimize severe hypoxia prior to laryngoscopy and endotracheal intubation in patients with acute respiratory failure.

Abstract
Background: Endotracheal intubation in the intensive care unit (ICU) is a high-risk procedure. Competence in endotracheal intubation is a requirement for Pulmonary and Critical Care Medicine (PCCM) training programs, but fellow experience as the primary operator in intubating ICU patients has not been described on a large scale. Objective: We hypothesized that significant variation surrounding endotracheal intubation practices in medical ICUs exists in U.S. PCCM training programs. Methods: We administered a survey to a convenience sample of U.S. PCCM fellows to elicit typical intubation practices in the medical ICU. Results: Eighty-nine discrete U.S. PCCM and Internal Medicine Critical Care Medicine training programs (77% response rate) were represented. At 43% of programs, the PCCM fellow was “always or almost always” designated the primary operator for intubation of a medical ICU patient, whereas at 21% of programs, the PCCM fellow was “rarely or never” the primary operator responsible for intubating in the ICU. Factors influencing this variation included time of day, hospital policies, attending skill or preference, ICU census and acuity, and patient factors. There was an association between location of the training program, but not program size, and whether the PCCM fellow was the primary operator. Conclusion: There is significant variation in whether PCCM fellows are the primary operators to intubate medical ICU patients during training. Further work should explore how this variation affects fellow career development and competence in intubation.

Abstract
INTRODUCTION Tracheal intubation is one of the most daily practiced procedures performed in intensive care unit (ICU). It is associated with severe life-threatening complications, which can lead to intubation-related cardiac arrest. Using a preshaped endotracheal tube plus stylet may have potential advantages over endotracheal tube without stylet. The stylet is a rigid but malleable introducer which fits inside the endotracheal tube and allows for manipulation of the tube shape; to facilitate passage of the tube through the laryngeal inlet. However, some complications from stylets have been reported including mucosal bleeding, perforation of the trachea or oesophagus and sore throat. The use of a stylet for first-attempt intubation has never been assessed in ICU and benefit remains to be established. METHODS AND ANALYSIS The endotracheal tube plus stylet to increase first-attempt success during orotracheal intubation compared with endotracheal tube alone in ICU patients (STYLETO) trial is an investigator-initiated, multicentre, stratified, parallel-group unblinded trial with an electronic system-based randomisation. Patients will be randomly assigned to undergo the initial intubation attempt with endotracheal tube alone (ie,without stylet, control group) or endotracheal tube + stylet (experimental group). The primary outcome is the proportion of patients with successful first-attempt orotracheal intubation. The single, prespecified, secondary outcome is the incidence of complications related to intubation, in the hour following intubation. Other outcomes analysed will include safety, exploratory procedural and clinical outcomes. ETHICS AND DISSEMINATION The study project has been approved by the appropriate ethics committee 'Comité-de-Protection-des-Personnes Nord-Ouest3-19.04.26.65808 Cat2 RECHMPL19_0216/STYLETO2019-A01180-57'". Informed consent is required. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences. If combined use of endotracheal tube plus stylet facilitates tracheal intubation of ICU patients compared with endotracheal tube alone, its use will become standard practice, thereby decreasing first-attempt intubation failure rates and, potentially, the frequency of intubation-related complications.

Abstract
Context: Mortality related to intubation occurs as a result of multiple factors such as patient's condition, operator's skills, equipment use, intubation time, duration of laryngoscopy and intubation, and drugs and dosage used for endotracheal intubation (ETI). Objectives: This systematic review and meta-analysis aimed to determine mortality related to intubation and the overall intensive care unit (ICU) mortality rate in adult general ICUs. Methods: We performed a systematic review and meta-analysis on randomized clinical trials and cohort and cross-sectional research from three electronic databases with hand searching. The studies reported mortality related to intubation and the overall ICU mortality rate in adult general ICUs. Our search resulted in 28 published articles without any restriction on date and language. The systematic review and meta-analysis was performed to examine mortality related to intubation and the overall ICU mortality rate. Results: We found 7,866 articles in the literature review from the three databases based on our keywords, of which 28 studies were eligible to include in the study. We observed that mortality related to intubation and the overall ICU mortality rate in intubated patients were 1% and 30%, respectively. Conclusions: This was the first comprehensive systematic review on mortality related to intubation and the overall ICU mortality rate in adult general ICUs, which showed the current care of ETI. However, it was associated with increased complications, which may increase mortality.

Characteristics of Effective Teachers of Invasive Bedside Procedures: A Multi-institutional Qualitative Study. Chest 2020; 158:2047-2057. [PMID: 32428512 DOI: 10.1016/j.chest.2020.04.060] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 04/20/2020] [Accepted: 04/26/2020] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Faculty supervision of invasive bedside procedures (IBPs) in the ICU may enhance procedural education and ensure patient safety. However, there is limited research on teaching effectiveness in the ICU, and there are no best teaching practices regarding the supervision of IBPs. RESEARCH QUESTION We conducted a multi-institutional qualitative study of pulmonary and critical care medicine faculty and fellows to better understand characteristics of effective IBP teachers. STUDY DESIGN AND METHODS Separate focus groups (FGs) were conducted with fellows and faculty at four large academic institutions that were geographically distributed across the United States. FGs were facilitated by a trained investigator, audio-recorded, and transcribed verbatim for analysis. Themes were identified inductively and compared with constructs from social and situated learning theories. Data were analyzed between and across professional groups. Qualitative research software (NVivo; QSR International) was used to facilitate data organization and create an audit trail of the analysis. A multidisciplinary research team was engaged to minimize interpretive bias. RESULTS Thirty-three faculty and 30 fellows participated. Inductive analysis revealed three categories of themes among successful IBP teachers: traits, behaviors, and context. Traits included calm demeanor, trust, procedural competence, and effective communication. Behaviors included leading preprocedure huddles to assess learners' experiences and define expectations; debriefing to provide feedback; and allowing appropriate autonomy. Context included learning climate, levels of distraction, patient acuity, and institutional culture. INTERPRETATION We identified specific traits and behaviors of effective IBP teachers that intersect with the practice environment, which highlights the challenge of teaching IBPs. Notably, FG participants emphasized interpersonal, more than technical, aspects of successful IBP teachers. These findings should inform future curricula on teaching IBPs in the ICU, standardize IBP teaching for pulmonary and critical care medicine fellows, and reduce patient injury from procedural complications.

Abstract
An emergency physician (EP) is often the first health care provider to evaluate, resuscitate, and manage a critically ill patient. In recent years, the annual hours of critical care delivered in emergency departments (EDs) across the United States increased more than 200% (Herring et al., 2013). In addition to seeing more critically ill patients, EPs are often tasked with providing critical care long beyond the initial resuscitation period. In fact, more than 50% of ED patients that require admission to the intensive care unit (ICU) remain in the ED for more than 6 h (Rose et al., 2016). Longer ED boarding times for critically ill patients is associated with a negative impact on inpatient morbidity and mortality (Mathews et al., 2018). It is during these early hours of critical illness, while the patient is in the ED, where lives can be saved or lost. Therefore, it is important for the EP to be knowledgeable about recent developments in critical care medicine. This review summarizes important articles published in 2018 pertaining to the resuscitation and care of select critically ill patients. We chose these articles based on our opinion of the importance of the study findings and their application to clinical care in the ED. The following topics are covered: cardiac arrest, post-arrest care, septic shock, rapid sequence intubation, mechanical ventilation, fluid resuscitation, and metabolic acidosis.

J Surg Res 2019; 247:344-349. [PMID: 31761442 DOI: 10.1016/j.jss.2019.10.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2019] [Revised: 09/16/2019] [Accepted: 10/01/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Competency-based medical education has renewed focus on the attainment and evaluation of resident skill. Proper evaluation is crucial to inform educational interventions and identify residents in need of increased training and supervision. Currently, there is a paucity of studies rigorously evaluating resident chest tube insertion skill. MATERIALS AND METHODS Residents of all training levels before their intensive care unit rotation or currently rotating through the intensive care unit were invited to participate. Trainees inserted a thoracostomy tube on a high-fidelity simulator. Their performances were recorded and scored by blinded raters using the validated TUBE-iCOMPT rubric. Surgical and nonsurgical residents were compared. RESULTS Forty-nine residents participated; 30 from nonsurgical and 19 from surgical training programs. Overall, trainees were most deficient in the "preprocedural checks" and "patient positioning and local anesthetic" domains. Surgical trainees demonstrated higher chest tube insertion skill than their nonsurgical peers (median total score 88 [interquartile range, 74-90] versus 75 [interquartile range, 66-85], respectively, P = 0.01), particularly in the "patient positioning" and "blunt dissection" domains (P = 0.01 and P = 0.03, respectively). These differences were no longer significant when controlled for experience and Advanced Trauma Life Support certification. CONCLUSIONS Overall, surgical residents were more skilled than nonsurgical residents in tube thoracostomy placement. Relative skill deficits within the domains of chest tube insertion have also been identified among residents of different specialties. These areas can be targeted with educational interventions to improve resident performance, and ultimately, patient safety.

Abstract
OBJECTIVES To determine the prevalence of and risk factors for cardiac arrest during intubation in ICU, as well as the association of ICU intubation-related cardiac arrest with 28-day mortality. DESIGN Retrospective analysis of prospectively collected data. SETTING Sixty-four French ICUs. PATIENTS Critically ill patients requiring intubation in the ICU. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS During the 1,847 intubation procedures included, 49 cardiac arrests (2.7%) occurred, including 14 without return of spontaneous circulation (28.6%) and 35 with return of spontaneous circulation (71.4%). In multivariate analysis, the main predictors of intubation-related cardiac arrest were arterial hypotension (systolic blood pressure < 90 mm Hg) prior to intubation (odds ratio = 3.406 [1.797-6.454]; p = 0.0002), hypoxemia prior to intubation (odds ratio = 3.991 [2.101-7.583]; p < 0.0001), absence of preoxygenation (odds ratio = 3.584 [1.287-9.985]; p = 0.0146), overweight/obesity (body mass index > 25 kg/m; odds ratio = 2.005 [1.017-3.951]; p = 0.0445), and age more than 75 years old (odds ratio = 2.251 [1.080-4.678]; p = 0.0297). Overall 28-day mortality rate was 31.2% (577/1,847) and was significantly higher in patients who experienced intubation-related cardiac arrest than in noncardiac arrest patients (73.5% vs 30.1%; p < 0.001). After multivariate analysis, intubation-related cardiac arrest was an independent risk factor for 28-day mortality (hazard ratio = 3.9 [2.4-6.3]; p < 0.0001). CONCLUSIONS ICU intubation-related cardiac arrest occurs in one of 40 procedures with high immediate and 28-day mortality. We identified five independent risk factors for cardiac arrest, three of which are modifiable, possibly to decrease intubation-related cardiac arrest prevalence and 28-day ICU mortality.

Abstract
RATIONALE Hypoxemia is a common complication during tracheal intubation of critically ill adults and is a frequently used endpoint in airway management research. Identifying patients likely to experience low oxygen saturations during tracheal intubation may be useful for clinical practice and clinical trials. OBJECTIVES To identify risk factors for lower oxygen saturations and severe hypoxemia during tracheal intubation of critically ill adults and develop prediction models for lowest oxygen saturation and hypoxemia. METHODS Using data on 433 intubations from two randomized trials, we developed linear and logistic regression models to identify preprocedural risk factors for lower arterial oxygen saturations and severe hypoxemia between induction and 2 minutes after intubation. Penalized regression was used to develop prediction models for lowest oxygen saturation after induction and severe hypoxemia. A simplified six-point score was derived to predict severe hypoxemia. RESULTS Among the 433 intubations, 426 had complete data and were included in the model. The mean (standard deviation) lowest oxygen saturation was 88% (14%); median (interquartile range) was 93% (83-98%). Independent predictors of severe hypoxemia included hypoxemic respiratory failure as the indication for intubation (odds ratio [OR], 2.70; 95% confidence interval [CI], 1.58-4.60), lower oxygen saturation at induction (OR, 0.92 per 1% increase; 95% CI, 0.89-0.96 per 1% increase), younger age (OR, 0.97 per 1-year increase; 95% CI, 0.95-0.99 per 1-year increase), higher body mass index (OR, 1.03 per 1 kg/m2; 95% CI, 1.00-1.06 per 1 kg/m2), race (OR, 4.58 for white vs. black; 95% CI, 1.97-10.67; OR, 4.47 for other vs. black; 95% CI, 1.19-16.84), and operator with fewer than 100 prior intubations (OR, 2.83; 95% CI, 1.37-5.85). A six-point score using the identified risk factors predicted severe hypoxemia with an area under the receiver operating curve of 0.714 (95% CI, 0.653 to 0.778). CONCLUSIONS Lowest oxygen saturation and severe hypoxemia during tracheal intubation in the intensive care unit can be accurately predicted using routinely available preprocedure clinical data, with saturation at induction and hypoxemic respiratory failure being the strongest predictors. A simple bedside score may identify patients at risk for hypoxemia during intubation to help target preventative interventions and facilitate enrichment in clinical trials.

Abstract
Background Intensive care medicine is a relatively young discipline that has rapidly grown into a full-fledged medical subspecialty. Intensivists are responsible for managing an ever-increasing number of patients with complex, life-threatening diseases. Several factors may influence their performance, including age, training, experience, workload, and socioeconomic context. The aim of this study was to examine individual- and work-related aspects of the Latin American intensivist workforce, mainly with academic appointments, which might influence the quality of care provided. In consequence, we conducted a cross-sectional study of intensivists at public and private academic and nonacademic Latin American intensive care units (ICUs) through a web-based electronic survey submitted by email. Questions about personal aspects, work-related topics, and general clinical workflow were incorporated. Results Our study comprised 735 survey respondents (53% return rate) with the following country-specific breakdown: Brazil (29%); Argentina (19%); Chile (17%); Uruguay (12%); Ecuador (9%); Mexico (7%); Colombia (5%); and Bolivia, Peru, Guatemala, and Paraguay combined (2%). Latin American intensivists were predominantly male (68%) young adults (median age, 40 [IQR, 35–48] years) with a median clinical ICU experience of 10 (IQR, 5–20) years. The median weekly workload was 60 (IQR, 47–70) h. ICU formal training was between 2 and 4 years. Only 63% of academic ICUs performed multidisciplinary rounds. Most intensivists (85%) reported adequate conditions to manage patients with septic shock in their units. Unsatisfactory conditions were attributed to insufficient technology (11%), laboratory support (5%), imaging resources (5%), and drug shortages (5%). Seventy percent of intensivists participated in research, and 54% read scientific studies regularly, whereas 32% read no more than one scientific study per month. Research grants and pharmaceutical sponsorship are unusual funding sources in Latin America. Although Latin American intensivists are mostly unsatisfied with their income (81%), only a minority (27%) considered changing to another specialty before retirement. Conclusions Latin American intensivists constitute a predominantly young adult workforce, mostly formally trained, have a high workload, and most are interested in research. They are under important limitations owing to resource constraints and overt dissatisfaction. Latin America may be representative of other world areas with similar challenges for intensivists. Specific initiatives aimed at addressing these situations need to be devised to improve the quality of critical care delivery in Latin America.

Abstract
INTRODUCTION Critically ill patients with acute respiratory, neurological or cardiovascular failure requiring invasive mechanical ventilation are at high risk of difficult intubation and have organ dysfunctions associated with complications of intubation and anaesthesia such as hypotension and hypoxaemia. The complication rate increases with the number of intubation attempts. Videolaryngoscopy improves elective endotracheal intubation. McGRATH MAC is the lightest videolaryngoscope and the most similar to the Macintosh laryngoscope. The primary goal of this trial was to determine whether videolaryngoscopy increased the frequency of successful first-pass intubation in critically ill patients, compared to direct view Macintosh laryngoscopy. METHODS AND ANALYSIS MACMAN is a multicentre, open-label, randomised controlled superiority trial. Consecutive patients requiring intubation are randomly allocated to either the McGRATH MAC videolaryngoscope or the Macintosh laryngoscope, with stratification by centre and operator experience. The expected frequency of successful first-pass intubation is 65% in the Macintosh group and 80% in the videolaryngoscope group. With α set at 5%, to achieve 90% power for detecting this difference, 185 patients are needed in each group (370 in all). The primary outcome is the proportion of patients with successful first-pass orotracheal intubation, compared between the two groups using a generalised mixed model to take the stratification factors into account. ETHICS AND DISSEMINATION The study project has been approved by the appropriate ethics committee (CPP Ouest 2, # 2014-A00674-43). Informed consent is not required, as both laryngoscopy methods are considered standard care in France; information is provided before study inclusion. If videolaryngoscopy proves superior to Macintosh laryngoscopy, its use will become standard practice, thereby decreasing first-pass intubation failure rates and, potentially, the frequency of intubation-related complications. Thus, patient safety should benefit. Further studies would be warranted to determine whether videolaryngoscopy is also beneficial in the emergency room and for prehospital emergency care. TRIAL REGISTRATION NUMBER NCT02413723; Pre-results.

Abstract
OBJECTIVE Given increasing evidence supporting a real-time ultrasound (US)-guided approach for subclavian vein (SCV) central venous catheter (CVC) insertion as compared with the traditional landmark approach, we sought to develop a standardized curriculum to offer healthcare providers a means to attain increased competency and confidence in US-guided SCV CVC insertion. DESIGN Retrospective review of prospectively collected data. SETTING Single institution's American College of Surgeons Level 1 Accredited Education Institute within an academic tertiary care center. SUBJECTS A total of 77 residents and midlevel providers working in our surgical intensive care unit. INTERVENTIONS Providers participated in a tiered educational module designed to teach safe US-guided SCV CVC insertion. The education consisted of a multimedia didactic presentation and a hands-on simulation session, including US anatomy on live subjects and anatomical model-based SCV CVC insertion. MEASUREMENTS AND MAIN RESULTS Assessment of the effect of education included a written examination and confidence survey, administered pre- and postintervention, and videotaped simulation session graded by blinded expert evaluators. Of the 77 participants, 70 participants completed a posttest with a median 5-point increase in score compared with that of the pretest score (p < 0.0001). Confidence ratings based on a 5-point Likert scale demonstrated an increase in confidence in SCV CVC insertion (p < 0.0001), using the landmark approach (p < 0.0001), using US-guided approach (p < 0.0001), and in use of US to image the SCV (p < 0.0001). Postgraduate year-1 residents had lower mean global rating score (p = 0.010) than any other participants. CONCLUSIONS This comprehensive hands-on teaching module-based curriculum enhanced learner knowledge of and confidence in US-guided SCV CVC insertion. This module can be implemented in simulation centers for teaching safe and successful SCV CVC insertion.

Abstract
INTRODUCTION Extracorporeal carbon dioxide removal (ECCO2R) has been proposed for hypercapnic respiratory failure in chronic obstructive pulmonary disease (COPD) exacerbations, to avoid intubation or reduce length of invasive ventilation. Balance of risks, efficacy, and benefits of ECCO2R in patients with COPD is unclear. METHODS We systematically searched MEDLINE and EMBASE to identify all publications reporting use of ECCO2R in COPD. We looked at physiological and clinical efficacy. A favorable outcome was defined as prevention of intubation or successful extubation. Major and minor complications were compiled. RESULTS We identified 3123 citations. Ten studies (87 patients), primarily case series, met inclusion criteria. ECCO2R prevented intubation in 65/70 (93%) patients and assisted in the successful extubation of 9/17 (53%) mechanically ventilated subjects. One case-control study matching to noninvasively ventilated controls reported lower intubation rates and hospital mortality with ECCO2R that trended toward significance. Physiological data comparing pre- to post-ECCO2R changes suggest improvements for pH (0.07-0.15 higher), PaCO2 (25 mmHg lower), and respiratory rate (7 breaths/min lower), but not PaO2/FiO2. Studies reported 11 major (eight bleeds requiring blood transfusion of 2 units, and three line-related complications, including one death related to retroperitoneal bleeding) and 30 minor complications (13 bleeds, five related to anticoagulation, and nine clotting-related device malfunctions resulting in two emergent intubations). CONCLUSION The technique is still experimental and no randomized trial is available. Recognizing selection bias associated with case series, there still appears to be potential for benefit of ECCO2R in patients with COPD exacerbations. However, it is associated with frequent and potentially severe complications. Higher-quality studies are required to better elucidate this risk-benefit balance.

Abstract
OBJECTIVES Tracheal intubation of ICU patients is frequently associated with severe hypoxemia. Although noninvasive ventilation reduces desaturation during intubation of severely hypoxemic patients, it does not allow for per-procedure oxygenation and has not been evaluated in mild-to-moderate hypoxemic patients for whom high-flow nasal cannula oxygen may be an alternative. We sought to compare pre- and per-procedure oxygenation with either a nonrebreathing bag reservoir facemask or a high-flow nasal cannula oxygen during tracheal intubation of ICU patients. DESIGN Prospective quasi-experimental before-after study (ClinicalTrials.gov: NCT01699880). SETTING University hospital medico-surgical ICU. PATIENTS All adult patients requiring tracheal intubation in the ICU were eligible. INTERVENTIONS In the control (before) period, preoxygenation was performed with a nonrebreathing bag reservoir facemask and in the change of practice (after) period, with high-flow nasal cannula oxygen. MEASUREMENTS AND MAIN RESULTS Primary outcome was median lowest SpO2 during intubation, and secondary outcomes were SpO2 after preoxygenation and number of patients with saturation less than 80%. One hundred one patients were included. Median lowest SpO2 during intubation were 94% (83-98.5) with the nonrebreathing bag reservoir facemask versus 100% (95-100) with high-flow nasal cannula oxygen (p < 0.0001). SpO2 values at the end of preoxygenation were higher with high-flow nasal cannula oxygen than with nonrebreathing bag reservoir facemask and were correlated with the lowest SpO2 reached during the intubation procedure (r = 0.38, p < 0.0001). Patients in the nonrebreathing bag reservoir facemask group experienced more episodes of severe hypoxemia (2% vs 14%, p = 0.03). In the multivariate analysis, preoxygenation with high-flow nasal cannula oxygen was an independent protective factor of the occurrence of severe hypoxemia (odds ratio, 0.146; 95% CI, 0.01-0.90; p = 0.037). CONCLUSIONS High-flow nasal cannula oxygen significantly improved preoxygenation and reduced prevalence of severe hypoxemia compared with nonrebreathing bag reservoir facemask. Its use could improve patient safety during intubation.
