RESUMO
A tracheobronchial avulsion is a very rare and serious condition that occurs mostly due to blunt trauma chest caused by high-speed traffic accidents. In this article, we present a challenging case of a 20-year-old male who had a right tracheobronchial transection with carinal tear which was repaired on cardiopulmonary bypass (CPB) through right thoracotomy. Challenges faced and a review of literature will be discussed. How to cite this article: Kaur A, Singh VP, Gautam PL, Singla MK, Krishna MR. Tracheobronchial Injury: Role of Virtual Bronchoscopy.

RESUMO
BACKGROUND: Percutaneous dilatation tracheostomy (PDT) is required in patients with novel coronavirus disease-2019 (COVID-19) with severe respiratory involvement, but the procedure needs modification to minimize the risk of aerosol exposure to caregivers. AIM AND OBJECTIVE: To share the experience of apnea approach of PDT in COVID patients. Also, to demonstrate the safety of the technique for healthcare workers (HCWs) and patients with respect to hemodynamic and oxygenation parameters. The incidence of adverse events and difficulties during the procedure were also recorded. MATERIALS AND METHODS: According to this modified approach, percutaneous tracheostomy was performed with apnea technique during open tracheal steps (video attached) and the endotracheal tube was withdrawn to the level of cords under video-laryngoscopic guidance. STUDY DESIGN: A retrospective data analysis of all the tracheostomy procedures (PDT) performed with the apnea technique during the COVID era (June-September) in non-COVID and COVID patients in intensive care units (ICUs). RESULTS: During these 4 months, 74 PDT procedures were performed in both COVID and non-COVID patients in the ICUs of our hospital. Out of these, PDT with apnea technique was performed in 45 patients (61%). This technique was successful in 44 patients (97.7%) with mean apnea time of 110 + 8.6 seconds. There was no significant (p < 0.05) change in mean arterial pressure and oxygen saturation of 15 COVID patients in pre-PDT and immediate post-PDT period. None of the six team members performing PDT had symptoms or tested positive for COVID-19. CONCLUSION: PDT with apnea technique can be performed to minimize the risk of aerosol exposure and does not compromise the quality of care. It is safe both for the patient and HCWs.

RESUMO
Background and Aims: Ultrasonographic assessment of diaphragmatic function can be a useful bedside tool in the weaning and extubation of mechanically ventilated patients, especially in patients with difficult weaning, in whom diaphragmatic weakness is suspected. Thus, this study was planned to assess the role of bedside sonographic assessment of diaphragmatic indices such as diaphragmatic thickening fraction (DTf) and diaphragmatic excursion (DE) in predicting successful extubation or extubation failure in weaning eligible patients by comparing the measurements with outcome. Methods: This prospective observational study was conducted on 50 mechanically ventilated, weaning-ready patients during the spontaneous breathing trial (SBT). The DE and DTf of patients were noted along with conventional parameters of weaning. Probability value <0.05 was considered statistically significant. Receiver operating characteristic (ROC) curves were used for analysis. Area under the curve (AUC) was measured, and sensitivity and specificity for different cut-off values were estimated. Results: Out of 50 patients, 15 (30%) had SBT failure and 4 had extubation failure. The group with SBT failure had significantly higher rapid shallow breathing index (RSBI) and airway occlusion pressure (P0.1s), whereas DE and DTf were lower compared to the SBT successful group. Strong correlation existed between RSBI, DTf, DE and P0.1s. DTf of nearly 24% (sensitivity 93.5%, specificity 94.7%) and DE of 1.10 cm (84% sensitivity, 89.5% specificity) were associated with best outcome. Conclusion: Along with conventional parameters of weaning, sonographic assessment of diaphragmatic parameters can be useful in predicting the success of SBT and in avoiding unnecessary extubation failures and thereby help in achieving a successful weaning outcome.
