Rabbit training model for establishing an emergency front of neck airway in children.

BACKGROUND: A 'cannot intubate, cannot oxygenate' (CICO) situation is rare in paediatric anaesthesia, but can always occur in children under certain emergency situations. There is a paucity of literature on specific procedures for securing an emergency invasive airway in children younger than 6 yr. A modified emergency front of neck access (eFONA) technique using a rabbit cadaver model was developed to teach invasive airway protection in a CICO situation in children. METHODS: After watching an instructional video of our eFONA technique (tracheotomy, intubation with Frova catheter over which a tracheal tube is inserted), 29 anaesthesiologists performed two separate attempts on rabbit cadavers. The primary outcome was the success rate and the performance time overall and in subgroups of trained and untrained participants. RESULTS: The overall success rate across 58 tracheotomies was 95% and the median performance time was 67 s (95% confidence interval [CI], 56-76). Performance time decreased from the first to the second attempt from 72 s (95% CI, 57-81) to 61 s (95% CI, 50-81). Performance time was 59 s (95% CI, 49-79) for untrained participants and 72 s (95% CI, 62-81) for trained participants. Clinical experience and age of the participants was not correlated with performance time, whereas the length of the tracheotomy incision showed a significant correlation (P=0.006). CONCLUSION: This eFONA training model for children facilitates rapid skill acquisition under realistic anatomical conditions to perform an emergency invasive airway in children younger than 2 yr.

Recommendations of the Spanish Society of Otolaryngology and Head and Neck Surgery for performing tracheotomies in patients infected by the coronavirus, Covid-19. / Recomendaciones de la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello para la realización de traqueotomías en relación con pacientes infectados por coronavirus COVID-19.

The recent COVID-19 (coronavirus) pandemic is causing an increase in the number of patients who, due to their pulmonary ventilatory status, may require orotracheal intubation. COVID-19 infection has demonstrated a high rate of transmissibility, especially via the respiratory tract and by droplet spread. The Spanish Society of Otolaryngology and Head and Neck Surgery, based on the article by Wei et al. of 2003 regarding tracheotomies performed due to severe acute respiratory syndrome (SARS), has made a series of recommendations for the safe performance of tracheotomies.

A Surgical Safety Checklist for Performing Tracheotomy in Patients with Coronavirus Disease 19.

Performance of tracheotomy is a potential necessary step in the patient with coronavirus disease 19 (COVID-19) and prolonged mechanical ventilation. Due to viral aerosolization, tracheotomy carries a high risk of transmission of COVID-19 to the health care team performing the procedure. We share our institution's surgical safety checklist for performing tracheotomy in patients with COVID-19, including key modifications intended to mitigate risk to the surgical team.

Development and validation of a model to predict the need for emergency front-of-neck airway procedures in trauma patients.

The present study aimed to develop and validate a model for predicting the need for emergency front-of neck airway (eFONA) procedures among trauma patients. This was a multicentre retrospective cohort study using data from the Japan Trauma Data Bank between January 2004 and December 2017. Only adult trauma patients were included. The cohort was divided into development and validation cohorts. A simple scoring system was developed to predict the necessity for emergency front-of neck airway procedures in the development cohort using a logistic regression model. The external validity and diagnostic ability of the scoring system was assessed in the validation cohort. In total, 198,182 out of 294,274 patients were included; emergency front-of-neck airway occurred in 467 patients (0.24%) they were divided into development (n = 100,120 with 0.22% undergoing emergency front-of neck airway) and validation (n = 98,062 with 0.25% undergoing emergency front-of neck airway) cohorts. The 'eFONA' prediction scoring system was developed in the development cohort, with a score of +1 for each of the following: Eye opening (no eye opening in response to any stimuli); Fall from height or motor bike; Oral-maxillofacial injury; Neck tracheal injury; and Airway management by paramedics. In the validation cohort, the C-statistic of the scoring system was 0.820. Setting the cut-off value at one for rule-out, the sensitivity and negative likelihood ratios were 0.86 and 0.22, respectively. Setting the cut-off value at two for rule-in, the specificity and positive likelihood ratios were 0.91 and 6.6, respectively. The present scoring system may assist in predicting the need for emergency front-of neck airway procedures among the general trauma population.

Competency-Based Assessment Tool for Pediatric Tracheotomy: International Modified Delphi Consensus.

OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric tracheotomy. STUDY DESIGN: Blinded, modified, Delphi consensus process. METHODS: Using the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as "keep" or "remove," and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven-point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items. RESULTS: The first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as "keep," and 137 comments were incorporated. In the second round, 30 task-specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task-Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus. CONCLUSIONS: It is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency-based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.

Performance of emergency surgical front of neck airway access by head and neck surgeons, general surgeons, or anaesthetists: an in situ simulation study.

BACKGROUND: The 'cannot intubate cannot oxygenate' (CICO) emergency requires urgent front of neck airway (FONA) access to prevent death. In cases reported to the 4th National Audit Project, the most successful FONA was a surgical technique, almost all of which were performed by surgeons. Subsequently, UK guidelines adopted surgical cricothyroidotomy as the preferred emergency surgical FONA technique. Despite regular skills-based training, anaesthetists may still be unwilling to perform an emergency surgical FONA. Consultant anaesthetists, head and neck surgeons, and general surgeons were compared in a high-fidelity simulated emergency. We hypothesised that head and neck surgeons would successfully execute emergency surgical FONA faster than anaesthetists and general surgeons. METHODS: We recruited 15 consultants from each specialty (total of 45) at a single tertiary care hospital in the UK. All agreed to participate in an in situ high-fidelity simulation of an 'anaesthetic emergency'. Participants were not told in advance that this would be a CICO scenario. RESULTS: There were no significant differences in total time to successful ventilation between anaesthetists, head and neck surgeons and general surgeons (median 86 vs 98 vs 126 s, respectively, P=0.078). Anaesthetists completed the emergency surgical FONA procedure significantly faster than general surgeons (median 50 vs 86 s, P=0.018). Despite this strong performance, qualitative data suggested some anaesthetists still believed 'surgeons' best placed to perform emergency surgical FONA in a genuine CICO situation. CONCLUSION: Anaesthetists regularly trained in emergency surgical FONA function at levels comparable with head and neck surgeons and should feel empowered to lead this procedure in the event of a CICO emergency.

The impact of didactic read-aloud action cards on the performance of cannula cricothyroidotomy in a simulated 'can't intubate can't oxygenate' scenario.

Significant benefits have been demonstrated with the use of peri-operative checklists. We assessed whether a read-aloud didactic action card would improve performance of cannula cricothyroidotomy in a simulated 'can't intubate, can't oxygenate' scenario. A 17-step action card was devised by an expert panel. Participants in their first 4 years of anaesthetic training were randomly assigned into 'no-card' or 'card' groups. Scenarios were video-recorded for analysis. Fifty-three participants (27 no-card and 26 card) completed the scenario. The number of steps omitted was mean (SD) 6.7 (2.0) in the no-card group vs. 0.3 (0.5); p < 0.001 in the card group, but the no-card group was faster to oxygenation by mean (95% CI) 35.4 (6.6-64.2) s. The Kappa statistic was 0.84 (0.73-0.95). Our study demonstrated that action cards are beneficial in achieving successful front-of-neck access using a cannula cricothyroidotomy technique. Further investigation is required to determine this tool's effectiveness in other front-of-neck access situations, and its role in teaching or clinical management.

[Not Available]. / Atemwegsmanagement - Tracheotomie Revisited.

Since 5000 years tracheotomy is a common way for airway management. Generally, Tracheotomy will be divided in a surgical tracheotomy the percutaneous Tracheotomy. The surgical Tracheotomy takes place in the operation theater. The percutaneous Tracheotomy is one of the standard procedures in the Intensive care unit. There are many methods to perform the percutaneous Tracheotomy. The gist of every method is the seldinger procedure. Bronchoscopic supervision during the whole procedure is one of the most important things to prevent complications. However percutaneous and surgical tracheotomy are safe and have a low rate of complications.

Randomized Controlled Trial Assessing the Feasibility of Shortened Fasts in Intubated ICU Patients Undergoing Tracheotomy.

OBJECTIVE: American Society of Anesthesiology guidelines recommend preoperative fasts of 6 hours after light snacks and 8 hours after large meals. These guidelines were designed for healthy patients undergoing elective procedures but are often applied to intubated intensive care unit (ICU) patients. ICU patients undergoing routine procedures may be subjected to unnecessary prolonged fasts. This study tests whether shorter fasts allow for better nutrition delivery and patient outcomes without increasing the risk. STUDY DESIGN: Randomized blinded controlled trial. SETTING: Tertiary academic medical center. SUBJECTS: ICU patients undergoing bedside tracheotomy. METHODS: Intubated ICU patients who were receiving enteral feeding and for whom bedside tracheotomy was indicated were enrolled prospectively and randomly allocated to 2 parallel preoperative fasting regimens: a 6-hour fast (control) and a 45-minute fast (intervention). Patients were assessed for aspiration, caloric delivery, metabolic markers, and infectious and noninfectious complications. RESULTS: Twenty-four patients were enrolled and randomized. There were no complications related to the procedure. There were no cases of intraoperative aspiration identified. There was a single postoperative pneumonia in the control group. Median (interquartile range) length of fast and caloric delivery were significantly different between the control group and the shortened fast group: 22 hours (18, 34) vs 14 hours (5, 25; P < .001) and 429 kcal (57, 1125) vs 1050 kcal (825, 1410; P = .01), respectively. CONCLUSIONS: Shortening preoperative fasts in intubated ICU patients allowed for better caloric delivery in the preoperative period.

[Tracheostomy techniques]. / Tracheotomietechniken.

Due to the comprehensive establishment of modern techniques, tracheostomy has become a routine procedure in intensive care units (ICU). The negative effects of prolonged translaryngeal intubation on the laryngeal and tracheal mucosa up to tracheal stenosis can be reduced by tracheostomy. Furthermore, long-term ventilation is facilitated; however, there is no clear evidence on the optimal timing of tracheostomy in critically ill patients. The specific indications and contraindications of surgical as well as percutaneous tracheostomy must be strictly observed for a safe and successful intervention. Exchanging the tracheostomy tube may lead to potentially dangerous situations especially after percutaneous tracheostomy. A standardized and structured approach is therefore recommended.

Use of ultrasound guidance to improve the safety of percutaneous dilatational tracheostomy: a literature review.

Patients in ICUs frequently require tracheostomy for long-term ventilator support, and the percutaneous dilatational tracheostomy (PDT) method is preferred over surgical tracheostomy. The use of ultrasound (US) imaging to guide ICU procedures and interventions has recently emerged as a simple and noninvasive tool. The current evidence regarding the applications of US in PDT is encouraging; however, the exact role of US-guided dilatational tracheostomy (US-PDT) remains poorly defined. In this review, we describe the best available evidence concerning the safety and efficacy of US-PDT and briefly delineate the general principles of US image generation for the airway and of US-PDT procedures.

[Results of an artificial airway management protocol in critical patients subjected to mechanical ventilation]. / Resultados de un protocolo de manejo sobre la vía aérea artificial en pacientes críticos sometidos a ventilación mecánica.

OBJECTIVE: To determine the results of the implementation of a protocol in an intensive care unit (ICU) referred to critically ill patients requiring a prolonged artificial airway. DESIGN: A prospective, observational cohort study was carried out. INTERVENTION: Management strategies were established on the airway by endotracheal intubation (ETI) or tracheostomy, and guidelines were developed for action in the decannulation process. SETTING: A polyvalent ICU. PATIENTS: We studied 169 patients subjected to mechanical ventilation (MV), 67 with ETI ≥ 10 days of MV and 102 with percutaneous (PT) or surgical tracheostomy (TQ). VARIABLES OF INTEREST: ICU and hospital stays, days of ETI and MV, mortality, tracheostomy, anatomical risk factors, surgical complications, and postoperative decannulation period. RESULTS: ETI versus tracheotomy involved fewer days of MV (17 vs. 30 days, p<0.001), a shorter ICU stay (20 vs. 35 days, p<0.001), and a shorter hospital stay (34 vs. 51 days, p<0.001).There were more TQ procedures in patients with risk factors (47% TP vs. 89% TQ, p<0.001). Intraoperative minor bleeding was the most common complication, being associated with TQ (31% vs. 11%, p = 0.03). TP was associated with a shorter cannulationperiod (25 days vs. 34 days, p<0.04). CONCLUSIONS: The protocol variants showed no differences in terms of complications and mortality, when orienting application to patients with similar characteristics.

Tracheotomy-related catastrophic events: results of a national survey.

OBJECTIVES/HYPOTHESIS: To gather qualitative and semiquantitative information about catastrophic complications during and following tracheotomy. STUDY DESIGN: National survey distributed to American Academy of Otolaryngology-Head and Neck Surgery members via the Academy weekly email newsletter during April and May 2011. METHODS: A total of 478 respondents provided estimates of the number of four specific tracheotomy-related complications (innominate artery fistula, esophageal fistula, acute tracheotomy occlusion, and obstructing granuloma), all catastrophic events, and events resulting in death or permanent disability encountered during their careers. There were 253 respondents who provided 405 free-text descriptions of specific events. RESULTS: The respondents experienced approximately one catastrophic event every 10 years and one event resulting in death or permanent disability every 20 years. More than 90% occurred more than 1 week after surgery. Categories of physicians who experienced more events per year included academic physicians and laryngologists. Pediatric otolaryngologists had twice as many innominate artery fistulas per year of practice as others. Qualitative (free-text) descriptions of the most serious events demonstrated that more of these events involved loss of airway and volume bleeds, usually from innominate or carotid artery erosion. Many of the events due to airway loss involved potentially correctable deficits in family education, nursing care, home care, and other structural factors. CONCLUSIONS: Even when we allow for selection bias, these data suggest that a substantial number of tracheotomy complications leading to death or permanent disability occur at a national level. The vast majority of events occur more than 1 week after the procedure. Many of the described events were caused by factors that should be amenable to prospective system improvement strategies.

Surveillance and management practices in tracheotomy patients.

OBJECTIVES/HYPOTHESIS: To ascertain the surveillance and management practices for tracheotomy patients. STUDY DESIGN: Survey of tracheotomy management. METHODS: An electronically distributed 26-question survey was distributed under the auspices of the American Academy of Otolaryngology-Head and Neck Surgery Foundation. RESULTS: There were 478 responses. The mean number of years in practice was 21.2 years (standard deviation [SD], 11.0 years). Sixty-five percent of respondents perform mainly adult tracheotomy. There is variation in surveillance patterns of immediate, postoperative, intermediate, and long-term surveillance. On average, respondents follow a fresh tracheotomy daily for about 6 days, monthly for about 3 months, and long-term surveillance every 4 months on average. Almost all respondents perform long-term surveillance during routine tracheotomy changes; 61.4% perform this surveillance with an endoscope, and a minority rely on history and examination. The mean frequency of tracheotomy tube changes was 2 months (SD, 2.2 months; median, 1.1 month; range, 0.06-12 months). Two hundred sixty-one respondents have or have used a decannulation algorithm. The vast majority, 96.2%, are comfortable with their current management practices. Over half of the respondents perceive value in a clinical practice guideline to help them with standardizing care, and 80% of respondents feel that it would assist other specialties in the care and surveillance of tracheotomy patients. CONCLUSIONS: There is marked variability in the surveillance and management of tracheotomy patients. There exists opportunity to improve care through standardization of surveillance and management of these patients.

Health information management and perceptions of the quality of care for children with tracheotomy: a qualitative study.

BACKGROUND: Children with tracheotomy receive health care from an array of providers within various hospital and community health system sectors. Previous studies have highlighted substandard health information exchange between families and these sectors. The aim of this study was to investigate the perceptions and experiences of parents and providers with regard to health information management, care plan development and coordination for children with tracheotomy, and strategies to improve health information management for these children. METHODS: Individual and group interviews were performed with eight parents and fifteen healthcare (primary and specialty care, nursing, therapist, equipment) providers of children with tracheotomy. The primary tracheotomy-associated diagnoses for the children were neuromuscular impairment (n = 3), airway anomaly (n = 2) and chronic lung disease (n = 3). Two independent reviewers conducted deep reading and line-by-line coding of all transcribed interviews to discover themes associated with the objectives. RESULTS: Children with tracheotomy in this study had healthcare providers with poorly defined roles and responsibilities who did not actively communicate with one another. Providers were often unsure where to find documentation relating to a child's tracheotomy equipment settings and home nursing orders, and perceived that these situations contributed to medical errors and delayed equipment needs. Parents created a home record that was shared with multiple providers to track the care that their children received but many considered this a burden better suited to providers. Providers benefited from the parent records, but questioned their accuracy regarding critical tracheotomy care plan information such as ventilator settings. Parents and providers endorsed potential improvement in this environment such as a comprehensive internet-based health record that could be shared among parents and providers, and between various clinical sites. CONCLUSIONS: Participants described disorganized tracheotomy care and health information mismanagement that could help guide future investigations into the impact of improved health information systems for children with tracheotomy. Strategies with the potential to improve tracheotomy care delivery could include defined roles and responsibilities for tracheotomy providers, and improved organization and parent support for maintenance of home-based tracheotomy records with web-based software applications, personal health record platforms and health record data authentication techniques.

Practice patterns after tracheotomy in infants younger than 2 years.

OBJECTIVES: To report survey results of members of the American Society of Pediatric Otolaryngology (ASPO) on the practice patterns of surveillance endoscopy and management of suprastomal granuloma (SSG) in children younger than 2 years with indwelling tracheostomy tubes and to review our internal practice patterns. PATIENTS: All patients younger than 2 years who underwent tracheotomy between 1996 and 2006 at a tertiary children's hospital. INTERVENTIONS: (1) Retrospective medical chart summary and (2) ASPO-approved and -administered online surveys to the membership of a 14-question survey on indications for infant tracheotomy, indications for bronchoscopy after tracheotomy, and treatment preferences for SSG in this population. MAIN OUTCOME MEASURES: Summary and findings of survey results and of data collected from medical chart review, including demographics, medical comorbidities, age at time of tracheotomy, indications for tracheotomy, frequency of bronchoscopy after tracheotomy, frequency of observed SSG, and interventions for SSG. RESULTS: Seventy-five ASPO members completed the online surveys. Practice patterns varied for frequency of bronchoscopy: only as needed, every 12 months, every 6 months, and every 3 months were reported by 38% (n = 26), 25% (n = 17), 24% (n = 17), and 9% (n = 6) of ASPO members, respectively. Most important indications for bronchoscopy were preparation for laryngotracheal reconstruction and decannulation (100% [n = 65] and 92% [n = 60], respectively), bleeding (76% [n = 59]), and difficult tracheostomy tube changes (70% [n = 57]). Lumen obstruction of 25% to 50% and 50% to 75% by SSG would likely receive intervention (30% [n = 22] and 14% [n = 11], respectively) with skin hook eversion and removal being the most popular technique. We reviewed the medical records of a total of 201 infants who underwent tracheotomy at our institution (110 boys [54.7%]). Indications included ventilator dependence (32.2%), craniofacial anomaly (15.0%), cardiopulmonary insufficiency(15.0%), neuromuscular indication (15.0%), and subglottic stenosis (6.7%). Thirty patients (14.9%) were premature (mean gestational age, 27 weeks). Median age at time of tracheotomy was 4 months for premature infants and 3 months for term infants. Practice patterns regarding endoscopy and SSG management varied widely within our own institution. A total of 205 bronchoscopies were performed on 109 patients during the study period. At the time of first bronchoscopy 43 of 109 patients were noted to have an SSG (39.4%). Elective removal of SSG occurred in 20 of 43 cases (46.5%), and 9 of 20 patients were noted to have recurrent SSG at subsequent endoscopy (45%). In addition, of the 23 children who did not have intervention for their SSG, 15 of 23 had spontaneous resolution and no appreciable SSG at the time of follow-up endoscopy (65.0%). CONCLUSIONS: There are currently various practice patterns for surveillance endoscopy and management of SSG in children younger than 2 years with indwelling tracheostomy tubes. Development of clinical practice guidelines on this topic may improve patient care and reduce unnecessary procedures.

Who is performing percutaneous tracheotomies? Practice patterns of surgeons in the USA.

Tracheotomy is one of the most common surgical procedures performed in the ICU setting. Traditionally tracheotomy has been performed by otolaryngologists as well as general surgeons. While percutaneous tracheotomy (PT) has been available for some time, it has only recently gained widespread acceptance with the advent of convenient and safe kits. Over the past decade, there has been increased utilization of this technique. However, there is a relative reluctance of certain surgical specialties to perform and train residents in PT; a previous study identified that only 29% of otolaryngology head and neck surgery (OTO-HNS) departments in the USA perform PT. In this study we aim to investigate the trends of PT usage in general surgery training programs and compare them to those previously described in otolaryngology programs. The study design is multi-institution physician survey and the study method was a survey of 250 general surgery program directors. This survey was identical to a published survey of OTO-HNS and a head-to-head comparison of results was performed. The response rate was 53% (133 programs). 89% of general surgery programs performed open tracheotomy on a regular basis. 75% performed percutaneous tracheotomy on a regular basis. 79% use the Ciaglia Blue Rhino method. Simultaneous video bronchoscopy was used by 67%. 83% of general surgery residency programs train their residents in PT. 61% felt that PT was either safer than or equal to open tracheotomy. PT is performed in a majority of general surgery residency programs and taught to their trainees. This is in contrast to otolaryngology residency programs, which have been shown to prefer open tracheotomies in both practice and teaching. This trend may severely impact the skills of the next generation of otolaryngologists.

Emergency cricothyroidotomy: a randomised crossover study of four methods.

Emergency physicians and registrars performed emergency cricothyroidotomy on an artificial airway model using a standard surgical approach and three common commercial products, participants had received no refresher training. The order in which the methods were used was randomised to minimise any learning effect. Three methods (standard surgical, Minitrach II, and Quicktrach) were universally successful in obtaining ventilation within 150 s, whilst the Melker kit had a 26% failure rate and significantly longer median time to ventilation (126 s vs
