Abstract
ABSTRACT Advanced airway management is a skill that is used every day in patient care settings throughout the world. Albeit common, it is not benign. Advanced airway management may either be elective or urgent; in either case, it may result in significant patient morbiidity and mortality. The complications of difficult or failed endotracheal intubation can be severe and include death or permanent neurologic injury. Difficulty or failure with advanced airway management often coincides with the onset of hypoxia. The onset of hypoxia affects both the patient and the airway manager. While hypoxemia may result in dysrhythmias and ultimately cardiac arrest for the patient, it adds time pressure and stress to the airway manager, and thus may impact successful performance. In this review, we will discuss how to identify patients at risk for rapid desaturation during advanced airway management. Additionally, methods of peri-oxygenation throughout the performance of airway management will be discussed.

Abstract
Emergency front-of-neck access refers to all techniques that deliver oxygen into the airway lumen through the anterior neck structures and encompasses access both through the cricothyroid membrane and the tracheal wall. There has yet to be a universal agreement regarding the preferred technique. A surgical incision is currently the most common approach in prehospital and in-hospital care. This review intends to review and summarize the existing clinical, basic science, and societal guidelines for eFONA.

Abstract
Adverse events associated with failed airway management may have catastrophic consequences, and despite many advances in knowledge, guidelines and equipment, airway incidents and patient harm continue to occur. Patient safety incident reporting systems have been established to facilitate a reduction in incidents. However, it has been found that corrective actions are inadequate and successful safety improvements scarce. The aim of this scoping review was to assess whether the same is true for airway incidents by exploring academic literature that describes system changes in airway management in high-income countries over the last 30 years, based on findings and recommendations from incident reports and closed claims studies. This review followed the most recent guidance from the Joanna Briggs Institute (JBI). PubMed, Ovid MEDLINE and Embase, the JBI database, SCOPUS, the Cochrane Library and websites for anaesthetic societies were searched for eligible articles. Included articles were analysed and data synthesised to address the review's aim. The initial search yielded 28,492 results, of which 111 articles proceeded to the analysis phase. These included 23 full-text articles, 78 conference abstracts and 10 national guidelines addressing a range of airway initiatives across anaesthesia, intensive care and emergency medicine. While findings and recommendations from airway incident analyses are commonly published, there is a gap in the literature regarding the resulting system changes to reduce the number and severity of adverse airway events. Airway safety management mainly focuses on Safety-I events and thereby does not consider Safety-II principles, potentially missing out on all the information available from situations where airway management went well.

Abstract
Oesophageal intubations are more common than may be realised and can potentially cause significant patient harm even if promptly identified and corrected. Reports of morbidity due to unrecognised oesophageal intubation continue to present in coroner and media reports. Therefore, it would be helpful to identify mechanisms to prevent these events and implement strategies to avoid and identify incorrect endotracheal tube placement. This analysis of oesophageal intubations reported to webAIRS aims to provide an in-depth analysis of all events in which oesophageal intubation occurred. WebAIRS is a web-based, bi-national incident reporting system collecting voluntarily reported anaesthetic events across Australia and New Zealand, with more than 10,500 incidents registered. A structured search through the webAIRS database identified 109 reports of oesophageal intubation reported between July 2009 and September 2022. A common cause of oesophageal intubation was the misidentification of the larynx due to a poor laryngeal view. Desaturation directly attributed to the misplaced endotracheal tube occurred in 43% of all reports. The authors precisely defined early recognised oesophageal intubation and delayed or unrecognised oesophageal intubation. Most reports (74%) described early recognition of the misplaced intubation, of which 27% led to directly contributed to hypoxia. Cardiovascular collapse as a direct consequence of the late recognition of oesophageal intubation was described in five (18%) of these events. There was inconsistency in end-tidal carbon dioxide monitoring and interpretation of the resulting waveform. Findings show that oesophageal intubation continues to be an issue in anaesthesia. Incidents described confusion in diagnosis, human factors issues and cognitive bias. Clear diagnostic guidance and treatment strategies are required to be developed, tested and implemented.

Abstract
PURPOSE Our study aimed to provide consensus and expert clinical practice statements related to airway management in critically ill adults with a physiologically difficult airway (PDA). METHODS An international Steering Committee involving seven intensivists and one Delphi methodology expert was convened by the Society of Critical Care Anaesthesiologists (SOCCA) Physiologically Difficult Airway Task Force. The committee selected an international panel of 35 expert clinician-researchers with expertise in airway management in critically ill adults. A Delphi process based on an iterative approach was used to obtain the final consensus statements. RESULTS The Delphi process included seven survey rounds. A stable consensus was achieved for 53 (87%) out of 61 statements. The experts agreed that in addition to pathophysiological conditions, physiological alterations associated with pregnancy and obesity also constitute a physiologically difficult airway. They suggested having an intubation team consisting of at least three healthcare providers including two airway operators, implementing an appropriately designed checklist, and optimizing hemodynamics prior to tracheal intubation. Similarly, the experts agreed on the head elevated laryngoscopic position, routine use of videolaryngoscopy during the first attempt, preoxygenation with non-invasive ventilation, careful mask ventilation during the apneic phase, and attention to cardiorespiratory status for post-intubation care. CONCLUSION Using a Delphi method, agreement among a panel of international experts was reached for 53 statements providing guidance to clinicians worldwide on safe tracheal intubation practices in patients with a physiologically difficult airway to help improve patient outcomes. Well-designed studies are needed to assess the effects of these practice statements and address the remaining uncertainties.

Abstract
BACKGROUND Fiberoptic intubation is an important method for tracheal intubation in patients with cervical spine injury. How to effectively and safely complete fiberoptic intubation while maintaining the stability of the cervical spine is very important. This study compared the efficiency and safety of fiberoptic intubation after anesthesia induction under different types of air pressure in patients with simulated cervical spinal injury. METHODS In total, 59 adult patients who underwent fiberoptic intubation with a cervical collar for simulated cervical spinal injury were randomly allocated to continuous positive-pressure oxygen, normal-pressure, or intermittent negative-pressure suction groups. After the induction of anesthesia and adequate 100% oxygenation, which confirmed effective neuromuscular blockade, it was deemed appropriate to begin fiberoptic intubation. In the continuous positive-pressure oxygen group, the fiberoptic device was connected through the negative-pressure suction path with 5 L/min oxygen. In the intermittent negative-pressure suction group, the fiberoptic device was connected to the negative-pressure suction device. In the normal-pressure group, the flexible fiberoptic device was not connected to either the oxygen source or the negative-pressure suction device. The intubation time was recorded as the primary outcome measure. The intubation success rate, number of attempts, minimum SpO2, objective lens contamination rate, and incidence of complications were also compared among the groups. RESULTS Compared with those in the other groups, the median (range) intubation time in the continuous positive-pressure group was 59 (36-181) seconds, which was significantly shorter than that in the normal-pressure group, 167 (46-181) seconds, and the intermittent negative-pressure suction group, 132.5 (38-181) seconds (P=0.04). The success rate of nasotracheal intubation was significantly greater in the continuous positive-pressure group (94.7%, 18/19) than in the normal-pressure group (50%, 10/20) and intermittent negative-pressure suction group (50%, 10/20) (P=0.004). There was a significant difference among the three groups (P=0.043). The median (range) minimum SpO2 during fiberoptic intubation was 100% (99-100%) in the continuous positive-pressure group, 100% (90-100%) in the normal-pressure group, and 99% (88-100%) in the intermittent negative-pressure suction group (P=0.029). However, no statistically significant difference was detected among the groups with complications. CONCLUSION The continuous use of positive-pressure oxygen via the negative-pressure suction pathway can improve the efficiency and safety of fiberoptic intubation in patients with simulated cervical spinal injury after anesthesia induction.

Abstract
BACKGROUND Failure to adhere to perioperative fasting requirements increases aspiration risk and can lead to delay or cancellation of surgery. Point of care gastric ultrasound may guide decision-making to delay, cancel or proceed with surgery. METHODS This study aimed to describe gastric contents using point of care gastric ultrasound in pediatric patients with known fasting guideline violations presenting for elective surgery. This was a single-center retrospectivechart review of gastric ultrasound scans in patients presenting for elective surgeries with "nothing by mouth" violation (per fasting guidelines) or unclear fasting status. The primary outcome is description of gastric contents using point of care ultrasound. The ultrasound findings were classified as low-risk for aspiration (empty, clear fluid < 1.5 ml/kg), high-risk (solids, clear fluid > 1.5 ml/kg), or inconclusive study. Gastric ultrasound findings were communicated to the attending anesthesiologist. For patients proceeding without delay the estimated time saved was defined as the difference between ultrasound scan time and presumed case start time based on American Society of Anesthesiologists fasting guidelines. RESULTS We identified 106 patients with a median age of 4.8 years. There were 31 patients (29.2%) that had ultrasound finding of high-risk gastric contents. These patients had cases that were delayed, cancelled or proceeded with rapid sequence intubation. Sixty-six patients (62.3%) were determined to be low-risk gastric contents and proceeded with surgery without delay. For these patients, a median of 2.6 h was saved. No aspiration events were recorded for any patients. CONCLUSIONS It is feasible to use preoperative point of care gastric ultrasound to determine stomach contents and risk-stratify pediatric patients presenting for elective surgical procedures with fasting non-adherence. Preoperative gastric ultrasound may have a role in determining changes in anesthetic management in this patient population.

Abstract
Apparently, understanding airway management status may help to reduce risk and improve clinical practice. Given these facts, our team conducted a second survey on the current status of airway management for mainland China following our 2016 national airway survey. The national survey was conducted from November 7 to November 28, 2022. An electronic survey was sent to the New Youth Anesthesia Forum, where Chinese anesthesiologists completed the questionnaire via WeChat. A total of 3783 respondents completed the survey, with a response rate of 72.14%. So far, in 2022, 34.84% of anesthesiologists canceled or delayed surgery at least once due to difficult airway. For the anticipated difficult airway management, 66.11% of physicians would choose awake intubation under sedation and topical anesthesia, while the percentage seeking help has decreased compared to the 2016 survey. When encountering an emergency, 74.20% of respondents prefer to use the needle cricothyrotomy, albeit less than a quarter have actually performed it. Anesthesiologists with difficult airway training experience reached 72.96%, with a significant difference in participation between participants in Tier 3 hospitals and those in other levels of hospitals (P < 0.001). The videolaryngoscope, laryngeal mask, and flexible intubation scope were equipped at 97.18%, 95.96%, and 62.89%, respectively. Additionally, the percentage of brain damage or death caused by difficult airways was significantly decreased. The study may be the best reference for understanding the current status of airway management in China, revealing the current advancements and deficiencies. The future focus of airway management remains on training and education.

Abstract
Gastric ultrasound estimates stomach contents in perioperative patients. A 10-year-old boy with abdominal rhabdomyosarcoma, who received abdominal radiation, developed gastroparesis and was scheduled for endoscopic gastrointestinal pyloric dilation. Point-of-care gastric ultrasound revealed gastric antral cross-sectional area of 6.5 cm2 (estimated gastric content ~30 mL). However, dynamic right-to-left ultrasound revealed more hypoechoic material in the fundus of the stomach. On induction ~125 mL of stomach contents was suctioned. Antral measurements may not accurately predict the stomach contents in the setting of a stiff/fixed antrum. Scanning from antrum to fundus determined contents more accurately, especially with a prior history of abdominal radiation.

Abstract
BACKGROUND Difficult airway remains a great challenge in pediatric anesthesia practice. Previously published data show the prevalence of difficult airways in pediatric population varies in a wide range. However, there is a lack of studies in the Asian region. METHODS This cross-sectional single-center study was conducted in a tertiary pediatric hospital in China from October 2022 to October 2023. The patients who underwent elective surgery under general anesthesia with tracheal intubation were recruited consecutively. Data on patient characteristics, airway assessment, and airway management information were collected. Multivariable logistic regression analysis was performed to detect the independent variables of difficult airway in pediatric patients. RESULTS A total of 18,491 pediatric patients were included in this study. The overall incidence of difficult airways was 0.22%, 39% of whom were unanticipated. Very few previous airway management information was available in the patients presented with a known difficult airway. Patients with younger age, higher American Society of Anesthesiologists (ASA) physical status classification grade, and presented for craniofacial and thoracic surgery were associated with higher incidence of difficult airway. Further multivariable logistic regression analysis revealed that age ≤28 days (OR=50.48), age between 28days and 1 year (OR=6.053), craniofacial surgery (OR=1.81), and thoracic surgery (OR=0.2465) were independent risk factors of increased incidence of difficult airway. CONCLUSIONS Our study showed the prevalence of difficult airways in pediatric surgical patients. Patient characteristics, age, and type of surgery were identified as the independent factors associated with increased occurrence of difficult airways. Unanticipated difficult airway was not unusual in our study population, even for the patients with previous surgical history.

Abstract
Importance Glucagon-like peptide-1 receptor agonist (GLP-1 RA) use is rapidly increasing in the US, driven by its expanded approval for weight management in addition to hyperglycemia management in patients with type 2 diabetes. The perioperative safety of these medications, particularly with aspiration risk under anesthesia, is uncertain. Objective To assess the association between GLP-1 RA use and prevalence of increased residual gastric content (RGC), a major risk factor for aspiration under anesthesia, using gastric ultrasonography. Design, Setting, and Participants This cross-sectional study prospectively enrolled patients from a large, tertiary, university-affiliated hospital from June 6 through July 12, 2023. Participants followed preprocedural fasting guidelines before an elective procedure under anesthesia. Patients with altered gastric anatomy (eg, from previous gastric surgery), pregnancy, recent trauma (<1 month), or an inability to lie in the right lateral decubitus position for gastric ultrasonography were excluded. Exposure Use of a once-weekly GLP-1 RA. Main Outcomes and Measures The primary outcome was the presence of increased RGC, defined by the presence of solids, thick liquids, or more than 1.5 mL/kg of clear liquids on gastric ultrasonography. Analysis was adjusted for confounders using augmented inverse probability of treatment weighting, a propensity score-based technique. Secondarily, the association between the duration of drug interruption and the prevalence of increased RGC was explored. Results Among the 124 participants (median age, 56 years [IQR, 46-65 years]; 75 [60%] female), the prevalence of increased RGC was 56% (35 of 62) in patients with GLP-1 RA use (exposure group) compared with 19% (12 of 62) in patients who were not taking a GLP-1 RA drug (control group). After adjustment for confounding, GLP-1 RA use was associated with a 30.5% (95% CI, 9.9%-51.2%) higher prevalence of increased RGC (adjusted prevalence ratio, 2.48; 95% CI, 1.23-4.97). There was no association between the duration of GLP-1 RA interruption and the prevalence of increased RGC (adjusted odds ratio, 0.86; 95% CI, 0.65-1.14). Conclusions and Relevance Use of a GLP-1 RA was independently associated with increased RGC on preprocedural gastric ultrasonography. The findings suggest that the preprocedural fasting duration suggested by current guidelines may be inadequate in this group of patients at increased risk of aspiration under anesthesia.

Abstract
The use of video laryngoscopes has enhanced the visualization of the vocal cords, thereby improving the accessibility of tracheal intubation. Employing artificial intelligence (AI) to recognize images obtained through video laryngoscopy, particularly when marking the epiglottis and vocal cords, may elucidate anatomical structures and enhance anatomical comprehension of anatomy. This study investigates the ability of an AI model to accurately identify the glottis in video laryngoscope images captured from a manikin. Tracheal intubation was conducted on a manikin using a bronchoscope with recording capabilities, and image data of the glottis was gathered for creating an AI model. Data preprocessing and annotation of the vocal cords, epiglottis, and glottis were performed, and human annotation of the vocal cords, epiglottis, and glottis was carried out. Based on the AI's determinations, anatomical structures were color-coded for identification. The recognition accuracy of the epiglottis and vocal cords recognized by the AI model was 0.9516, which was over 95%. The AI successfully marked the glottis, epiglottis, and vocal cords during the tracheal intubation process. These markings significantly aided in the visual identification of the respective structures with an accuracy of more than 95%. The AI demonstrated the ability to recognize the epiglottis, vocal cords, and glottis using an image recognition model of a manikin.

Abstract
At the Royal Perth Hospital, we have been developing and teaching a can't intubate, can't oxygenate (CICO) rescue algorithm for over 19 years, based on live animal simulation. The algorithm involves a 'cannula-first' approach, with jet oxygenation and progression to scalpel techniques if required in a stepwise fashion. There is little reported experience of this approach to the CICO scenario in humans. We present eight cases in which a cannula-first Royal Perth Hospital approach was successfully implemented during an airway crisis. We recommend that institutions teach and practice this approach; we believe it is effective, safe and minimally invasive when undertaken by clinicians who have been trained in it and have immediate access to the requisite equipment. The equipment is low cost, comprising a 14G Insyte cannula, saline, 5 ml syringe and a Rapid-O2. Training can be provided using low-fidelity manikins or part-task trainers.

Abstract
OBJECTIVES The primary aim of this study was to determine the average cricothyroid membrane (CTM) height in healthy volunteers, and the secondary aim was to determine the hypothetical success rate for emergency cricothyrotomy with a tracheal tube with an 8.0 mm outer diameter. METHODS This study included healthy volunteers aged 18 years and older. The participants' clinical characteristics were recorded, and their CTM height was measured using ultrasound, with their necks placed sequentially in the neutral and extension positions. The relationship between the CTM height and sex, age, height, weight, body mass index, and sternomental distance was evaluated using linear regression analysis. An equation that could estimate the height of the CTM was obtained with the parameters found significant in this analysis. RESULTS Of the 340 participants, 208 (61.2%) were male. The mean (SD) height of the CTM in the extension position was 9.60 (1.54) mm, and it was significantly shorter in the women than in the men (8.72 [1.19] mm vs. 10.16 [1.48] mm, p < 0.001). Among the participants of short stature, the CTM was significantly shorter, regardless of sex. The hypothetical success rate for emergency cricothyrotomy was 93.3% for the males and 73.5% for the females. The equation for estimating the height of the CTM in the extension position was determined as -4.36 + 5.27 × height (m) + 0.32 × sternomental distance (cm). CONCLUSIONS Since the CTM height may differ according to age, sex, and height, cricothyrotomy sets should be available in various outer diameters.

Abstract
BACKGROUND Tracheostomies are associated with high rates of complications and preventable harm. Safe tracheostomy management requires highly functioning teams and systems, but health care providers are poorly equipped with tracheostomy knowledge and resources. In situ simulation has been used as a quality improvement tool to audit multidisciplinary team emergency response in the actual clinical environment where care is delivered but has been underexplored for tracheostomy care. METHODS From July 2021 to May 2022, the study team conducted in situ simulations of a tracheostomy emergency scenario at Montefiore Medical Center to identify human errors and latent safety threats (LSTs). Simulations included structured debriefs as well as audiovisual recording that allowed for blind rating of these human errors and LSTs. Provider knowledge deficits were further characterized using pre-simulation quizzes. RESULTS Twelve human errors and 15 LSTs were identified over 20 simulations with 88 participants overall. LSTs were divided into the following categories: communication, equipment, and infection control. Only 50.0% of teams successfully replaced the tracheostomy tube within the scenario's five-minute time limit. In addition, knowledge gaps were highly prevalent, with a median pre-simulation quiz score of 46% (interquartile range 36-64) among participants. CONCLUSION An in situ simulation-based quality improvement approach shed light on human errors and LSTs associated with tracheostomy care across multiple settings in one health system. This method of engaging frontline health care provider key stakeholders will inform the development, adaptation, and implementation of interventions.

Abstract
Percutaneous dilatational tracheostomy (PDT) is a bedside medical procedure which sites a new tracheostomy tube in the front of the neck. The critical first step is accurate placement of a needle through the neck tissues into the trachea. Misplacement occurs in around 5% of insertions, causing morbidity, mortality, and delays to recovery. We aimed to develop and evaluate a prototype medical device to improve precision of initial PDT-needle insertion. The Guidance for Tracheostomy (GiFT) system communicates the relative locations of intra-tracheal target sensor and PDT-needle sensor to the operator. In simulated "difficult neck" models, GiFT significantly improved accuracy (mean difference 10.0 mm, ANOVA p < 0.001) with ten untrained laboratory-based participants and ten experienced medical participants. GiFT resulted in slower time-to-target (mean difference 56.1 s, p < 0.001) than unguided attempts, considered clinically insignificant. Our proof-of-concept study highlights GiFT's potential to significantly improve PDT accuracy, reduce procedural complications and offer bedside PDT to more patients.

Abstract
BACKGROUND Prediction of serious outcomes among patients with physiological instability is crucial in airway management. In this study, we aim to develop a score to predict serious outcomes following intubation in critically ill adults with physiological instability by using clinical and laboratory parameters collected prior to intubation. METHOD This single-center analytical cross-sectional study was conducted in the Emergency Department from 2016 to 2020. The airway score was derived using the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) methodology. To gauge model's performance, the train-test split technique was utilized. The discrete random number generation approach was used to divide the dataset into two groups: development (training) and validation (testing). The validation dataset's instances were used to calculate the final score, and its validity was measured using ROC analysis and area under the curve (AUC). By computing the Youden's J statistic using the metrics sensitivity, specificity, positive predictive value, and negative predictive value, the discriminating factor of the additive score was determined. RESULTS The mean age of the 1021 patients who needed endotracheal intubations was 52.2 years (± 17.5), and 632 (62%) of them were male. In the development dataset, there were 527 (64.9%) physiologically difficult airways, 298 (36.7%) post-intubation hypotension, 124 (12%) cardiac arrest, 347 (42.7%) shock index > 0.9, and 456 [56.2%] instances of pH < 7.3. On the contrary, in the validation dataset, there were 143 (68.4%) physiologically difficult airways, 33 (15.8%) post-intubation hypotension, 41 (19.6%) cardiac arrest, 87 (41.6%) shock index > 0.9, and 121 (57.9%) had pH < 7.3, respectively. There were 12 variables in the difficult airway physiological score (DAPS), and a DAPS of 9 had an area under the curve of 0.857. The accuracy of DAPS was 77%, the sensitivity was 74%, the specificity was 83.3%, and the positive predictive value was 91%. CONCLUSION DAPS demonstrated strong discriminating ability for anticipating physiologically challenging airways. The proposed model may be helpful in the clinical setting for screening patients who are at high risk of deterioration.

Huang S, Cao S, Sun X, Zhang J. Gastric point-of-care ultrasonography in patients undergoing radical gastrointestinal surgery before anesthetic induction: an observational cohort study. BMC Anesthesiol 2024; 24:90. [PMID: 38433227 PMCID: PMC10910806 DOI: 10.1186/s12871-024-02473-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Accepted: 02/26/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Pulmonary aspiration of gastric contents is a serious perioperative complication. Patients with gastric cancer may experience delayed gastric emptying. However, the role of qualitative and quantitative gastric ultrasound assessments in this patient population before anesthesia induction has not yet been determined. METHODS Adult patients with gastrointestinal cancer were recruited and examined using gastric point-of-care ultrasound (POCUS) before anesthetic induction from March 2023 to August 2023 in a tertiary cancer center. Three hundred patients with gastric cancer were conducted with POCUS prior to induction, and three hundred patients with colorectal cancer were included as controls. The cross-sectional area (CSA) of the gastric antrum and gastric volumes (GV) were measured and calculated. We determined the nature of the gastric contents and classified the antrum using a 3-point grading system. A ratio of GV to body weight > 1.5mL/Kg was defined as a high risk of aspiration. RESULTS In patients with gastric cancer, 70 patients were classified as grade 2 (23%, including 6 patients with solid gastric contents) and 63 patients (21%) were identified as having a high risk of aspiration. Whereas in patients with colorectal cancer, only 11 patients were classified as grade 2 (3.7%), and 27 patients (9.7%) were identified as having a high risk of aspiration. A larger tumor size (OR:1.169, 95% CI 1.045-1.307, P = 0.006), tumor located in antrum (OR:2.304, 95% CI 1.169-4.539,P = 0.016), gastrointestinal obstruction (OR:21.633, 95% CI 4.199-111.443, P < 0.0001) and more lymph node metastasis (OR:2.261, 95% CI 1.062-4.812, P = 0.034) were found to be positively while tumor site at cardia (OR:0.096, 95% CI 0.019-0.464, P = 0.004) was negatively associated with high aspiration risk in patients with gastric cancer. CONCLUSION The Gastric POCUS prior to induction provides an assessment of the status of gastric emptying and can identify the patients at high risk of aspiration, especially those with gastric cancer.

Comparison of UESCOPE VL 400, I-View, Non-Channeled Airtraq Videolaryngoscopes and Macintosh Laryngoscope for Tracheal Intubation in Simulated Out-of-Hospital Conditions: A Randomized Crossover Manikin Study. Healthcare (Basel) 2024; 12:452. [PMID: 38391827 PMCID: PMC10887893 DOI: 10.3390/healthcare12040452] [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: 01/15/2024] [Revised: 02/07/2024] [Accepted: 02/08/2024] [Indexed: 02/24/2024] Open
Abstract
The aim of the study was to test the hypothesis that the results obtained with three different types of video laryngoscopes (UESCOPE VL-400, I-View, Non-Channeled Aitraq) with and without an endotracheal stylet should be better than the results obtained with a Macintosh laryngoscope in a simulated out-of-hospital scenario by a person without clinical experience. Primary outcome measures were the time taken to successfully achieve tracheal intubation (TI). Secondary outcomes included the grade of glottic view (Cormack and Lehane grades 1-4), the incidence of successful TI, the number of audible dental clicks indicating potential dental damage, the level of effort required to perform TI, and the operator's comfort during the procedure. The time required to achieve tracheal intubation successfully was significantly longer with the Macintosh laryngoscope and Airtraq than with the other video laryngoscopes. The use of the stylet significantly reduced the time required for tracheal intubation with the Macintosh laryngoscope (21.8 sec. vs. 24.0 sec., p = 0.026), UESCOPE VL 400 (18.1 sec. vs. 23.4 sec., p = 0.013), and Airtraq (22.7 sec. vs. 34.5 sec., p < 0.001). There were no significant differences in intubation time when using the I-View with or without stylets. No differences were observed in the Cormack-Lehane grading. The success rate of intubation was 100% for the Macintosh and I-View laryngoscopes used with or without stylets and for the UESCOPE VL 400 and Airtraq laryngoscopes used with stylets. Without stylets, the success rate of intubation was 96.6% for the UESCOPE VL 400 and 86.6% for the Airtraq. There were no significant differences in the risk of dental damage between the Macintosh, UESCOPE VL 400, I-View, and Airtraq laryngoscopes, regardless of the use of stylets (without and with stylets). The use of stylets significantly reduced dental damage only for the Airtraq laryngoscope: 8 (26.6%) vs. 2 (6.6%). Statistically significant differences in perceived exertion were observed between the mentioned laryngoscopes, both with and without stylets. However, there were no differences in the comfort of use between the laryngoscopes, regardless of the use of stylets (without and with stylets. The use of stylets led to better comfort in the case of the Macintosh (2.5 vs. 3, p = 0.043) and UESCOPE VL 400 (2 vs. 3, p = 0.008) laryngoscopes. In our study, the I-View and UESCOPE VL-400 video laryngoscopes provided better intubation results than the Macintosh laryngoscope in terms of time needed to intubate, glottis visibility, and reduction in dental damage. The use of the stylet did not significantly improve the intubation results compared to the results obtained in direct laryngoscopy. Due to the small study group and the manikin model, additional studies should be performed on a larger study group.

Abstract
BACKGROUND AND IMPORTANCE Endotracheal intubation is a lifesaving procedure that is reportedly associated to a significant risk of adverse events. Recent trials have reported that the use of videolaryngoscope and of a stylet might limit this risk during emergency intubation. OBJECTIVES The objective of this study was to provide a national description of intubation practices in French Emergency Departments (EDs). SETTINGS AND PARTICIPANTS We conducted an online nationwide survey by sending an anonymous 37-item questionnaire via e-mail to 629 physicians in French EDs between 2020 and 2022. INTERVENTION A single questionnaire was sent to a sole referent physician in each ED. OUTCOME MEASURES AND ANALYSIS The primary endpoint was to assess the proportion of French EDs in which videolaryngoscopy was available for emergency intubation and its use in routine practice. Secondary endpoints included the presence of local protocol or standard of procedure for intubation, availability of capnography, and routine use of a stylet. MAIN RESULTS Of the surveyed EDs, 342 (54.4%) returned the completed questionnaire. A videolaryngoscope was available in 193 (56%) EDs, and direct laryngoscopy without a stylet was majorly used as the primary approach in 280 (82%) EDs. Among the participating EDs, 74% had an established protocol for intubation and 92% provided a capnography device for routine verification of tube position. In cases of difficult intubation, the use of a bougie was recommended in 227 (81%) EDs, and a switch to a videolaryngoscope in 16 (6%) EDs. The most frequently used videolaryngoscope models were McGrath Mac Airtraq (51%), followed by Airtraq (41%), and Glidescope (14%). CONCLUSION In this large French survey, the majority of EDs recommended direct laryngoscopy without stylet, with seldom use of videolaryngoscopy.

Abstract
We aimed to develop machine learning (ML)-based algorithms to assist physicians in ultrasound-guided localization of cricoid cartilage (CC) and thyroid cartilage (TC) in cricothyroidotomy. Adult female volunteers were prospectively recruited from two hospitals between September and December, 2020. Ultrasonographic images were collected via a modified longitudinal technique. You Only Look Once (YOLOv5s), Faster Regions with Convolutional Neural Network features (Faster R-CNN), and Single Shot Detector (SSD) were selected as the model architectures. A total of 488 women (mean age: 36.0 years) participated in the study, contributing to a total of 292,053 frames of ultrasonographic images. The derived ML-based algorithms demonstrated excellent discriminative performance for the presence of CC (area under the receiver operating characteristic curve [AUC]: YOLOv5s, 0.989, 95% confidence interval [CI]: 0.982-0.994; Faster R-CNN, 0.986, 95% CI: 0.980-0.991; SSD, 0.968, 95% CI: 0.956-0.977) and TC (AUC: YOLOv5s, 0.989, 95% CI: 0.977-0.997; Faster R-CNN, 0.981, 95% CI: 0.965-0.991; SSD, 0.982, 95% CI: 0.973-0.990). Furthermore, in the frames where the model could correctly indicate the presence of CC or TC, it also accurately localized CC (intersection-over-union: YOLOv5s, 0.753, 95% CI: 0.739-0.765; Faster R-CNN, 0.720, 95% CI: 0.709-0.732; SSD, 0.739, 95% CI: 0.726-0.751) or TC (intersection-over-union: YOLOv5s, 0.739, 95% CI: 0.722-0.755; Faster R-CNN, 0.709, 95% CI: 0.687-0.730; SSD, 0.713, 95% CI: 0.695-0.730). The ML-based algorithms could identify anatomical landmarks for cricothyroidotomy in adult females with favorable discriminative and localization performance. Further studies are warranted to transfer this algorithm to hand-held portable ultrasound devices for clinical use.

Abstract
BACKGROUND AND OBJECTIVES Intubation for acute stroke is common in the United States, with few established guidelines. METHODS This is a retrospective observational study of acute stroke admissions from 2011 to 2018 among fee-for-service Medicare beneficiaries aged 65-100 years. Patient demographics and chronic conditions as well as hospital characteristics were identified. We identified patient intubation, stroke subtype (ischemic vs intracerebral hemorrhage), and thrombectomy. Factors associated with intubation were identified by a linear probability model with intubation as the outcome and patient characteristics, stroke subtype, and thrombectomy as predictors, adjusting for within-hospital correlation. We compared hospital characteristics between adjusted intubation rate quartiles. We specified a linear probability model with 30-day mortality as the patient-level outcome and hospital intubation rate quartile as the categorical predictor, again adjusting for patient characteristics. We specified an analogous model for quartiles of hospital referral regions. RESULTS There were 800,467 stroke hospitalizations at 3,581 hospitals. Among 2,588 hospitals with 25 or more stroke hospitalizations, the median intubation rate was 4.8%, while a quarter had intubation rates below 2.4% and 10% had rates above 12.5%. Ischemic strokes had a 21% lower adjusted intubation risk than intracerebral hemorrhages (risk difference [RD] -21.1%, 95% CI -21.3% to -20.9%; p < 0.001), whereas thrombectomy was associated with a 19.2% higher adjusted risk (95% CI RD 18.8%-19.6%; p < 0.001). Women and older patients had lower intubation rates. Large, urban hospitals and academic medical centers were overrepresented in the top quartile of hospital adjusted intubation rates. Even after adjusting for available characteristics, intubated patients had a 44% higher mortality risk than non-intubated patients (p < 0.001). Hospitals in the highest intubation quartile had higher adjusted 30-day mortality (19.3%) than hospitals in the lowest quartile (16.7%), a finding that was similar when restricting to major teaching hospitals (22.3% vs 18.1% in the 4th vs 1st quartiles, respectively). There was no association between market quartile of intubation and patient 30-day mortality. DISCUSSION Intubation for acute stroke varied by patient and hospital characteristics. Hospitals with higher adjusted rates of intubation had higher patient-level 30-day mortality, but much of the difference may be due to unmeasured patient severity given that no such association was observed for health care markets.

Abstract
Ultrasound evaluation of the upper airway has emerged as an essential instrument for clinicians, offering real-time assessment that can help to guide interventions and improve patient outcomes. This review aims to provide health care providers with a practical approach to performing ultrasound evaluation of the upper airway, covering basic physics relevant to upper airway ultrasound, the identification of key anatomical structures, and elucidating its various clinical applications, such as prediction of difficult airway, confirmation of endotracheal intubation, and guidance for surgical airway procedures and airway blocks. We also discuss evidence-based training programs, limitations, and future directions of ultrasound imaging of the upper airway.

Abstract
BACKGROUND Emergency intubations are commonly associated with adverse events when performed in critically ill patients. A detailed look at intubation factors and their association with procedural success and mortality has yet to be fully conducted. METHODS A total of 299 successive intubations at a tertiary Veteran Affair hospital were analyzed. Situational factors, personnel involved, intubation indications, induction agents, and airway management techniques were prospectively collected and entered into univariable and multivariable analyses to identify factors associated with procedural difficulty and mortality. RESULTS The use of paralytics was associated with easier intubations (OR: 0.31, 95% CI: 0.11-0.87, p = .03). The use of direct laryngoscopy or video laryngoscopy had no significant association with difficult intubation. Factors associated with increased 30-day mortality were cardiac arrest (OR: 7.90, 95% CI: 2.77-22.50, p < .001), hypoxia as indication for intubation (OR: 2.31, 95% CI: 1.23-4.35, p = .009), and nadir SpO2 < 90% (OR: 2.70, 95% CI: 1.01-7.21, p = .048). Presence of an attending anesthesiologist during intubation was associated with a lower 30-day mortality (OR: 0.11, 95% CI: 0.04-0.29, p < .001). Factors associated with increased 90-day mortality were cardiac arrest (OR: 6.57, 95% CI: 2.23-19.34, p = .001), hypoxia as indication for intubation (OR: 1.97, 95% CI: 1.10-3.55, p = .023), and older age (OR: 1.38, 95% CI: 1.07-1.78, p = .013). Similarly, presence of an attending anesthesiologist was found to be associated with a lower 90-day mortality (OR: 0.19, 95% CI: 0.07-0.50, p = .001). CONCLUSION Cardiovascular and respiratory instability were associated with increased 30- and 90-day mortality. Presence of an attending anesthesiologist was associated with a better survival following intubation outside operating room.

Abstract
OBJECTIVE Difficult airway is one of the most common potential risk factors for increased fatality in craniofacial/plastic surgery patients. To date, there is no well-established and all-around difficult airway notification system in China, which has recently been recommended by existing guidelines to improve the care of patients with known difficult airways. This study aimed to investigate the current status of critical information communication concerning difficult airway management in our institute. METHODS Vital information required to establish a difficult airway registry and notification system was collected through a literature review and expert suggestions. After approval by the Research Ethics Board, 3 online questionnaires were developed and sent to surgeons, anesthesiologists, and proxies of the patients. Knowledge of difficult airways, the willingness to be involved in the difficult airway notification system, and the way to disseminate the information were investigated in the 3 groups. The specific information that was disseminated, required, and available was investigated in the anesthesiologist group. RESULTS Compared with the surgeons and anesthesiologists, significantly fewer patients knew the definition of a difficult airway and thought it was a potential risk factor. There were no significant differences in the willingness to be informed of the difficulty encountered during airway management. Significant differences were detected in the willingness and way to disseminate the airway information when the participants communicated with different groups. Significantly more patients would disseminate the information to the surgeon and significantly more surgeons would disseminate the information to the patient and the other surgeon. Significantly more anesthesiologists would disseminate the information to the patient and the other anesthesiologists. A significant difference was observed between what was expected and what was available for the anesthesiologist to retrieve the airway information of a patient with known airway difficulty. Significantly more anesthesiologists would notify only the patient of the diagnosis of a difficult airway both oral and written, whereas significantly more anesthesiologists would notify the other anesthesiologist of the specific difficulties in oral only. Most participants agreed to be involved in the difficult airway notification system despite the significantly lower percentage in the patient group (89%). CONCLUSIONS Difficult airway information dissemination is, at the time of this writing, ineffective, which leads to a large gap between the expectation and practice of the anesthesiologist when caring for a patient with a difficult airway. Thus, a difficult airway registry and notification system should be developed, that has a solid foundation in all the participants.

Abstract
There is a gradual shift in training and teaching methods in the medical field. We are slowly moving from the traditional model and adopting active learning methods like simulation-based training. Airway management is an essential clinical skill for any anaesthesiologist, and a trained anaesthesiologist must perform quick and definitive airway management using various techniques. Airway simulations have been used for the past few decades. It ensures active involvement, upgrading the trainees' airway management knowledge and skills, including basic airway skills, invasive procedures, and difficult clinical scenarios. Trainees also learn non-technical skills such as communication, teamwork, and coordination. A wide range of airway simulators are available. However, texture surface characteristics vary from one type to another. The simulation-based airway management training requires availability, understanding, faculty development, and a structured curriculum for effective delivery. This article explored the available evidence on simulation-based airway management teaching and training.

Abstract
OBJECTIVE The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an Intensive Care Unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018. METHODS Prospective, observational study comparing all intubations performed in our ICU over 2 periods: pre-protocol (January 2015-January 2019) and post-protocol (February 2019-July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded. RESULTS During the study period, 661 patients were intubated - 437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥ 2b in 7.6% vs. 29.8%, p < 0.001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs. 17.4%, p < 0.001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (p = 0.508). We did not find significant differences in complications between the periods studied. CONCLUSIONS Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.

Abstract
Complications and critical incidents arising during anaesthesia due to patient, surgical or anaesthetic factors, may cause harm themselves or progress to more severe events, including cardiac arrest or death. As part of the 7th National Audit Project of the Royal College of Anaesthetists, we studied a prospective national cohort of unselected patients. Anaesthetists recorded anonymous details of all cases undertaken over 4 days at their site through an online survey. Of 416 hospital sites invited to participate, 352 (85%) completed the survey. Among 24,172 cases, 1922 discrete potentially serious complications were reported during 1337 (6%) cases. Obstetric cases had a high reported major haemorrhage rate and were excluded from further analysis. Of 20,996 non-obstetric cases, 1705 complications were reported during 1150 (5%) cases. Circulatory events accounted for most complications (616, 36%), followed by airway (418, 25%), metabolic (264, 15%), breathing (259, 15%), and neurological (41, 2%) events. A single complication was reported in 851 (4%) cases, two complications in 166 (1%) cases and three or more complications in 133 (1%) cases. In non-obstetric elective surgery, all complications were 'uncommon' (10-100 per 10,000 cases). Emergency (urgent and immediate priority) surgery accounted for 3454 (16%) of non-obstetric cases but 714 (42%) of complications with severe hypotension, major haemorrhage, severe arrhythmias, septic shock, significant acidosis and electrolyte disturbances all being 'common' (100-1000 per 10,000 cases). Based on univariate analysis, complications were associated with: younger age; higher ASA physical status; male sex; increased frailty; urgency and extent of surgery; day of the week; and time of day. These data represent the rates of potentially serious complications during routine anaesthesia care and may be valuable for risk assessment and patient consent.

Abstract
OBJECTIVE To achieve consensus on critical steps and create an assessment tool for actual and simulated pediatric tracheostomy emergencies that incorporates human and systems factors along with tracheostomy-specific steps. METHODS A modified Delphi method was used. Using REDCap software, an instrument comprising 29 potential items was circulated to 171 tracheostomy and simulation experts. Consensus criteria were determined a priori with a goal of consolidating and ordering 15 to 25 final items. In the first round, items were rated as "keep" or "remove". In the second and third rounds, experts were asked to rate the importance of each item on a 9-point Likert scale. Items were refined in subsequent iterations based on analysis of results and respondents' comments. RESULTS The response rates were 125/171 (73.1%) for the first round, 111/125 (88.8%) for the second round, and 109/125 (87.2%) for the third round. 133 comments were incorporated. Consensus (>60% participants scoring ≥8, or mean score >7.5) was reached on 22 items distributed across three domains. There were 12, 4, and 6 items in the domains of tracheostomy-specific steps, team and personnel factors, and equipment respectively. CONCLUSIONS The resultant assessment tool can be used to assess both tracheostomy-specific steps as well as systems factors affecting hospital team response to simulated and clinical pediatric tracheostomy emergencies. The tool can also be used to guide debriefing discussions of both simulated and clinical emergencies, and to spur quality improvement initiatives.

Evidence suggests that its use improves outcomes in operating rooms, intensive care units, and emergency departments, as well as in sedation suites, in postanesthesia recovery units, and on general postsurgical wards. Capnography can accurately and rapidly detect respiratory, circulatory, and metabolic derangements. In addition to being useful for diagnosing and managing esophageal intubation, capnography provides crucial information when used for monitoring airway patency and hypoventilation in patients without instrumented airways. Despite its ubiquitous use in high-income-country operating rooms, deaths from esophageal intubations continue to occur in these contexts due to incorrect use or interpretation of capnography. National and international society guidelines on airway management mandate capnography's use during intubations across all hospital areas, and recommend it when ventilation may be impaired, such as during procedural sedation. Nevertheless, capnography's use across high-income-country intensive care units, emergency departments, and postanesthesia recovery units remains inconsistent. While capnography is universally used in high-income-country operating rooms, it remains largely unavailable to anesthesia providers in low- and middle-income countries. This lack of access to capnography likely contributes to more frequent and serious airway events and higher rates of perioperative mortality in low- and middle-income countries. New capnography equipment, which overcomes cost and context barriers, has recently been developed. Increasing access to capnography in low- and middle-income countries must occur to improve patient outcomes and expand universal health care. It is time to extend capnography's safety benefits to all patients, everywhere.

Abstract
Emergency airway management events are common, unpredictable and associated with high complication rates. This multicentre prospective observational study across eight acute NHS hospitals in southeast England reports the incidence and nature of non-theatre emergency airway management events. Data were collected from non-theatre emergency airway management, including adverse events, over a continuous 28-day window, and recorded on an electronic case report form. Events were classified according to type (advanced airway; simple airway; and cardiac arrest). A total of 166 events were recorded, with 111 advanced airway events involving tracheal intubation or tracheostomy management. Senior personnel with three or more years of airway management experience were present for 105/111 (95%) advanced airway management episodes. There was a significant reduction in consultant or equivalent presence out-of-hours (21/64, 33%) vs. in-hours (34/47, 72%) (p < 0.001). We found high utilisation of videolaryngoscopy (95/106, 90%) and universal use of capnography for all advanced airway management events. This was lower during cardiac arrest when videolaryngoscopy was used in 11/16 (69%) of tracheal intubations and capnography in 21/32 (66%) of all cardiac arrest episodes. Adverse outcomes during advanced airway management (excluding during cardiac arrest) occurred in 53/111 (48%) episodes, including hypoxia (desaturation to Sp O2 < 80% in 14/111, 13%) and hypotension (systolic blood pressure < 80 mmHg in 27/111, 25%). Adverse outcomes were not associated with time of day or experience level of airway practitioners. We conclude that there is a disparity between consultant presence for advanced airway interventions in- and out-of-hours; high utilisation of videolaryngoscopy and capnography, especially for advanced airway interventions; and a high incidence of hypotension and hypoxaemia, including critical values, during non-theatre airway management.

Abstract
BACKGROUND The anatomical characteristics of difficult airways can be analysed geometrically. This study aims to develop and validate a geometry-assisted difficult airway screening method (GADAS method) for difficult tracheal intubation. METHODS In the GADAS method, a geometric simulated model was established based on computer graphics. According to the law of deformation of the upper airway on laryngoscopy, the expected visibility of the glottis was calculated to simulate the real visibility on laryngoscopy. Validation of the new method: Approved by the Ethics Committee of Yijishan Hospital of Wannan Medical College. Adult patients who needed tracheal intubation under general anaesthesia for elective surgery were enrolled. The data of patients were input into the computer software to calculate the expected visibility of the glottis. The results of tracheal intubation were recorded by anaesthesiologists. The primary observation outcome was the screening performance of the expected visibility of the glottis for difficult tracheal intubation. RESULTS The geometric model and software of the GADAS method were successfully developed and are available for use. We successfully observed 2068 patients, of whom 56 patients had difficult intubation. The area under the receiver operating characteristic curve of low expected glottis visibility for predicting difficult laryngoscopy was 0.96 (95% confidence interval [CI]: 0.95-0.96). The sensitivity and specificity were 89.3% (95% CI: 78.1-96.0%) and 94.3% (95% CI: 93.2%-95.3), respectively. CONCLUSIONS It is feasible to screen difficult-airway patients by applying computer techniques to simulate geometric changes in the upper airway.

Abstract
OBJECTIVES Emergency intubation in children is an infrequent procedure both in the pre-hospital and hospital setting. The anatomical, physiological and situational challenges together with limited clinician exposure can make this a difficult procedure with high risk of adverse events. The aim of this collaborative study between a state-wide ambulance service and a tertiary children's hospital was to describe the characteristics of pre-hospital paediatric intubations by Intensive Care Paramedics. METHODS We conducted a retrospective review of state-wide ambulance service electronic patient care records (ePCRs) in Victoria, Australia, population: 6.5 million. Children aged 0-18 years who were attended by paramedics over a 12-month period that required advanced airway management were analysed for demographics and first-pass success rate. RESULTS Paramedics attended 2674 cases aged 0-18 years over the 12-month study period who received basic or advanced airway management. A total of 78 cases required advanced airway management. The median age of patients was 12 years (interquartile range 3-16) and most were male (60.2%). Sixty-eight patients (87.5%) were intubated successfully on the first attempt, first-pass success was lowest in children <1 year of age. The most common indications for pre-hospital intubation were closed head injury and cardiac arrest. It was not possible to report complication rates because of incomplete documentation. CONCLUSION Pre-hospital intubation in children is performed infrequently in an extremely unwell patient group. Continued high-level paramedic training is required to prevent adverse events and ensure patient safety.

The impact of introducing a videolaryngoscope in the initial training of laryngoscopy for undergraduate medical students: a simulation randomized trial. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2023; 73:532-538. [PMID: 33823211 PMCID: PMC10533965 DOI: 10.1016/j.bjane.2021.02.048] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 07/20/2020] [Accepted: 02/26/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Adequate and continuous airway management by health professionals is fundamental to ensure patient safety and protection. Among several techniques, laryngoscopy for orotracheal intubation is considered a basic skill, so it is taught and learned in medical school and used during the future years of professional practice. However, in some clinical scenarios, physical and anatomical characteristics can make laryngoscopy exceedingly difficult. In the last decade, some new devices have emerged to apply indirect or video-assisted imaging systems, so-called videolaryngoscopes. They have shown great efficiency in difficult intubation cases and have improved teaching and training. Our study introduced a videolaryngoscope, the McGrath... MAC, in the regular laryngoscopy training rotation for 3rd-year undergraduate medical students and evaluated whether there was any associated optimization of the students... PERFORMANCE METHOD Students from two different classes and years (2017 and 2018) were randomly divided into two groups and received theoretical and practical training in the techniques of Direct Laryngoscopy (DL) and Videolaryngoscopy (VL). The students in each group applied the manoeuvres and simulated three tracheal intubation attempts on mannequins. They were evaluated for their success rate on the first attempt, the time required to finalize the intubation, and the visualization of the glottic structures according to the classification of Cormack-Lehane (C&L). RESULTS Two hundred and four students with an average age of 21.ß...ß2 years participated in the study; the groups were similar. There was a significant difference between the VL and DL groups in the 1st attempt success rate (97% and 89.4%, respectively, p.ß=.ß0.0497 ... 95% CI), but such a difference was not seen for the other attempts or regarding the number of oesophageal intubations (3% and 7.7%). The students in the VL group were faster than those in the DL group in all intubation attempts; in parallel, the vast majority of the VL group reported excellent visualization conditions, with 75% of the attempts classified as Cormack-Lehane grade 1. CONCLUSION The introduction of a videolaryngoscope in medical students... training improved the visualization of anatomical structures and allowed tracheal intubation maneuvers to be performed faster and with a higher success rate on the first attempt. Thus, under the conditions of this prospective study, the videolaryngoscope had a positive impact on training and proved to be a promising tool for teaching laryngoscopy.

Abstract
BACKGROUND Anesthetic monitoring within standards defined by various professional anesthesia organizations has been shown to reduce perioperative mortality. Given the scarce resources for anesthesia and surgery in low- to middle-income countries, we sought to determine the availability of recommended monitoring devices in major referral hospitals in Kenya. METHODS We purposely selected the 16 major referral hospitals in Kenya. A cross-sectional survey was conducted in 103 operating theaters, 96 postanesthesia care unit (PACU) beds, and 16 areas where procedural sedation was routinely administered. A checklist questionnaire based on the Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines of 2015 was used to determine the availability of basic and functional monitoring devices. RESULTS We determined that only 1 of 16 (6.25%) hospitals had all the monitoring devices recommended by the AAGBI. Automated noninvasive blood pressure (NIBP) monitoring and pulse oximetry were present in all operating theaters. Continuous electrocardiography (ECG) was available in 102 of 103 (99%) operating theaters, skin temperature monitoring probes in 73 of 103 (70.9%), and capnography in 49 (47.6%). A nerve stimulator was accessible in 5 of 16 (31.25%) hospitals. There were functional patient monitors in all operating theaters (100%). One of the regional referral hospitals did not have a PACU. We encountered 9 of 96 (9.4%) PACU beds without any monitoring devices. Pulse oximetry was the most common device (84.4%) in the PACU beds equipped with monitoring. In 5 of 16 (31.25%) procedural sedation areas, pulse oximetry was the only monitoring device, whereas there were no devices in 2 of 16 (12.5%) areas. Portable multiparameter devices used for patient transport were present in 5 of 16 (31.25%) hospitals. CONCLUSIONS The availability of recommended monitoring devices in major referral hospitals in Kenya is inadequate. Thus, there are challenges to anesthetic monitoring in these hospitals, and perioperative patient safety is jeopardized. We recommend the universal provision of basic monitoring devices and suggest the use of the data collected in this study to affect policy change and safe anesthesia practice in our country.

Abstract
BACKGROUND Cricothyrotomy is a procedure performed to establish an airway in critical airway events. It is performed only rarely and anesthesiologists are often unprepared when called upon to perform it. This study aimed to simulate cricothyrotomy using pig larynx and trachea models to help anesthesiologists master cricothyrotomy and improve the ability to establish cricothyrotomy quickly. METHODS The porcine larynx and trachea were dissected and covered with pigskin to simulate the structure of the anterior neck of a human patient. An animal model of cricothyrotomy was established. Forty anesthesiologists were randomly divided into four groups. Each physician performed three rounds of cricothyrotomy, and recorded the time to accomplish each successful operation. After training the cricothyrotomy procedure, a questionnaire survey was conducted for the participating residents using a Likert scale. The participants were asked to score the utility of the training course on a scale of 1 ((minimum) to 5 ((maximum). RESULTS Through repeated practice, compared with the time spent in the first round of the operation (67 ± 29 s), the time spent in the second round of the operation (47 ± 21 s) and the time spent in the third round of the operation (36 ± 11 s) were significantly shortened (P < 0.05). Results of the survey after training were quite satisfied, reflecting increased the ability of proficiency in locating the cricothyroid membrane and performing a surgical cricothyrotomy. CONCLUSION The porcine larynx and trachea model is an excellent animal model for simulating and practicing cricothyrotomy, helping anesthesiologists to master cricothyrotomy and to perform it proficiently when required.

Abstract
INTRODUCTION Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE), if used for pre-oxygenation and apnoeic oxygenation, has the propensity to extend the safe apnoea time and thereby decrease the incidence of desaturation during rapid sequence induction (RSI) for emergency surgeries. Hence, we proposed to evaluate the comparative efficacy of pre-oxygenation with the use of conventional facemask breathing versus THRIVE during RSI in patients undergoing general anaesthesia (GA) for emergency surgeries. MATERIALS AND METHODS Eighty patients undergoing RSI under GA for emergency abdominopelvic surgery were divided randomly into two groups. Patients were preoxygenated for three minutes with 100% oxygen via either a high-flow nasal cannula at a flow of 60 L/minute using THRIVE or a tightly-held, snuggly-fitting facemask at a flow of 12L/minute using a circle system. RSI was administered followed by laryngoscopy and endotracheal intubation. Arterial partial pressure of oxygen (PaO2) measured immediately after successful endotracheal intubation was our primary outcome. The lowest peripheral oxygen saturation (SpO2), apnoea time, number of attempts at laryngoscopy, use of any rescue manoeuvres, and any adverse event were also recorded. Data thus collected were statistically analysed. RESULTS No statistically significant difference in PaO2 value was observed after successful intubation, lowest SpO2, apnoea time, number of attempts at laryngoscopy, use of any rescue manoeuvres, and adverse event between both the groups (p>0.05). CONCLUSION We conclude that though not superior to conventional facemasks, THRIVE is a safe, practicable, and efficient pre-oxygenation tool during RSI of GA for patients undergoing emergency surgeries.

Abstract
Introduction To compare the intubating conditions at 60 seconds between 4*ED95 dose of cisatracurium and 2*ED95 dose of cisatracurium in combination with priming and low dose ketamine. Primary Objective jaw relaxation for laryngoscopy, vocal cord position on laryngoscopy, and coughing or bucking response to intubation. Secondary Objective To compare the hemodynamic changes up 10 minutes after intubation in the two groups. In this prospective study, a total of 68 patients were undergoing general anesthesia for surgery with placement of endotracheal tube placement. Patients will be divided into two groups comprising 34 patients each. The patients were allocated one of the two groups by computerized randomization. *Group A received bolus dose of cisatracurium which is 0.2 mg/kg (4*ED95). **Group B received cisatracurium in dose of 0.1 mg/kg (2*ED95) with priming (which is 10% of the bolus dose) and low dose ketamine of about 0.5 mg/kg. It was possible to achieve acceptable laryngoscopy and intubating condition in both the groups within 90 seconds. When grades of laryngoscopy and ease of intubation were compared, 2*ED95 dose along with priming plus low dose ketamine produced superior results than 4*ED95 group. When the mean arterial pressure and pulse rate were compared between the two groups, it was observed that mean arterial pressure and pulse rate were only slightly higher in the 2*ED95 along with priming and ketamine.

Abstract
Tracheal intubation is one of the most frequently performed procedures in critically ill patients, and is associated with significant morbidity and mortality. Hemodynamic instability and cardiovascular collapse are common complications associated with the procedure, and are likely in patients with a physiologically difficult airway. Bedside point-of-care ultrasound (POCUS) can help identify patients with high risk of cardiovascular collapse, provide opportunity for hemodynamic and respiratory optimization, and help tailor airway management plans to meet individual patient needs. This review discusses the role of POCUS in emergency airway management, provides an algorithm to facilitate its incorporation into existing practice, and provides a framework for future studies.
