Multi-Disciplinary Simulation Training for Surgical Tracheostomy in Patients Mechanically Ventilated Secondary to Severe Acute Respiratory Syndrome Coronavirus-2.

Objective: A proportion of COVID-19 patients with severe respiratory manifestations of disease will require admission to intensive care for intubation and ventilation. When anticipating prolonged ventilation, the patient may proceed to surgical tracheostomy to afford safe respiratory wean. As surgical tracheostomy is an aerosol-generating procedure, it poses a high risk of viral transmission and ultimately may prompt anxiety and caution in participating staff members. We aimed to mitigate these risks by providing staff with appropriate training and experience to improve their confidence as well as practical ability. Methods: We developed a multi-disciplinary simulation training experience and checklist in order to optimize team performance during the high-stakes procedure. We evaluated staff confidence before and after the training with questionnaires. Results: Post-simulation, surgeons were more confident with donning the high-level personal protective equipment, and nurses were more confident in performing their role. Conclusions: Simulation allows the multi-disciplinary team an opportunity to practise high-risk procedures and prompts the team to assess staff knowledge base, troubleshoot queries, and teach roles and responsibilities in a safe environment. In the context of COVID-19, simulation encourages the staff's sense of preparedness and protection for true participation during a high-risk procedure.

Management of Laryngotracheal Stenosis in Obesity. Is This Another Co-morbidity that Can Be Improved with Weight Loss Following Bariatric Surgery?

PURPOSE: Bariatric surgery improves several obesity-related comorbidities. Laryngotracheal stenosis is a rare condition that is usually managed with repeated endoscopic airway interventions and reconstructive airway surgery. The outcome of these definitive operations is worse in individuals with obesity. There are no studies investigating the effect of weight loss following bariatric surgery in the management of laryngotracheal stenosis. MATERIALS AND METHODS: In an observational study, consecutive patients with a BMI over 35 kg/m2 and laryngotracheal stenosis were prospectively recruited to a bariatric and airway stenosis database in two tertiary care centres. Patients were treated with laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy and control subjects were managed conservatively. RESULTS: A total of eleven patients with an initial body mass index of 43 kg/m2 (37-45) were enrolled to this study. Six patients underwent bariatric surgery and five subjects were treated conservatively. After 12 months, the total weight loss of patients undergoing bariatric surgery was 19.4% (14-24%) whilst 2.3% (1-3%) in the control group. The annual number of endoscopic airway interventions following bariatric surgery reduced (p = 0.002). Higher weight loss in patients led to less frequent interventions compared to control subjects (p = 0.004). Patients undergoing laryngotracheal reconstruction following bariatric surgery needed less endoscopic intervention, an annual average of 1.9 interventions before vs 0.5 intervention after. Conservatively managed control subjects required more frequent endoscopic intervention, 1.8 before vs 3.4 after airway reconstruction. CONCLUSION: Bariatric surgery reduced the number of endoscopic airway interventions and enabled patients to undergo successful definitive airway reconstructive surgery.
