Case • PE • T 38.5, p116, 85/40 → 111/56, R 18, 84%/3L • Ill-appearing, alert but tangental • Bilateral crackles and rhonchi • Labs: • WBC 16, 20% bands, hgb 11, plt 266 • Lactate 3.7, BUN 22, Cr 0.8
Hospital Course • Initially treated for HCAP with Zosyn, Levaquin, and Vancomycin • Stress dose steroids • IVIG
9/1/11 • Reportedly, patient’s husband sneaks her extra antihistamine, dramamine, seroquel and tapentadol, and she has an aspiration event • Acute hypoxic respiratory failure • Emergent intubation
9/1/11 • Soon after intubation, patient has bronch with BAL • “proximal airways were normal in appearance” • BAL grows MRSA • A few hours later, she is noted to acutely decompensate and “blow up”
9/4/11 • Patient again decompensates, with increased hypoxia and subcutaneous emphysema, and transfer to IMC is requested
9/4/11 transfer to IMC • T 38.1, p123, 122/87, R 24 FiO2 100%, PEEP 11, Vt 6 ml/kg • Diffuse subcutaneous emphysema, crackles, edema
Hospital Course • Recurrent infectious complications and intermittent septic shock: • Acromobacter PNA • Persistent MRSA tracheobronchitis • C.diff colitis • VRE UTI • Treated with Vanc, linezolid, zosyn, ceftaroline, flagyl • Severe ARDS • Self extubation with emergent re-intubation on 9/13 • Eventually stabilizes, but unable to wean from vent
Hospital Course • Trach on 9/27/11
Tracheal injury associated with endotracheal intubation • Clinical presentation • How often does this happen? • What are the risk factors? How do we avoid it? • What is the treatment?
Tracheal injury/rupture • Rare condition with high morbidity and mortality • Most common cause is head and neck injury • Most common iatrogenic cause is orotracheal intubation; also can occur with tracheostomy, bronchoscopy, placement of stents, esophagectomy • Usually longitudinal rupture in distal third of membranous trachea Miñambres et al. European Journal of Cardio-thoracic Surgery 35 (2009) 1056—1062
Tracheal injury associated with endotracheal intubation • Clinical presentation: • Most common: subcutaneous emphysema, pneumomediastinum, pneumothorax, respiratory distress • dyspnea, dysphonia, cough, hemoptysis, and pneumoperitoneum • signs often develop immediately or soon after intubation, but can take several days to appear Miñambres et al. European Journal of Cardio-thoracic Surgery 35 (2009) 1056—1062
Diagnosis • Requires high clinical suspicion based on clinical s/sx • Confirmed by direct visualization of lesion with bronchoscopy • CT
Radiographic signs • Subcutaneous emphysema • Pneumomediastinum • Overdistended ETT cuff • On CT tracheal defect/perforation Am J Emerg Med 2004;22:289-293.
Tracheal injury associated with endotracheal intubation • How often does this happen? • Case reports, several case series and reviews • Incidence estimates from 0.005% - 0.37% of intubations, more common with double lumen tubes Medina et al. J Bras Pneumol. 2009;35(8):809-813 Miñambres et al. European Journal of Cardio-thoracic Surgery 35 (2009) 1056—1062
Tracheal injury associated with endotracheal intubation • Miñambres et al. Tracheal rupture after endotracheal intubation. Eur J Cardiothorac Surg. 2009;35(6):1056-62 • 182 cases of postintubation tracheal rupture. • mortality 22% • 86% women • Intubations: 14% “difficult”, 27% emergent • Increased mortality associated with age ( p = 0.015) and emergency intubation (RR = 3.11; p = 0.001)

Risk factors / mechanism for tracheal rupture with intubation Am J Emerg Med 2004;22:289-293.
Risk factors for tracheal injury with intubation • Why women? • Shorter, with use of improperly long tubes • Smaller tracheal diameters- more vulnerable to cuff overinflation Anesth Analg 2001;93:1270–1
How do I avoid tracheal injury with emergent intubation? • Recommendations for emergent intubation: • Select the proper size of endotracheal tube • Check all equipment before intubation • Check position of stylet (tip not beyond murphy’s eye) • Intubate gently and use RSI when necessary • Retract the stylet when balloon cuff passes through vocal cords • Inflate the cuff slowly with proper volume and pressure • Fix ETT tightly to reduce the possibility of tube movement • Deflate the cuff first when repositioning the tube Am J Emerg Med 2004;22:289-293.
Management of tracheal laceration or rupture • Traditionally early surgical repair was mainstay • Now many recommend conservative treatment if rupture < 2 cm, and if minimal non-progressive sxs and no air leak • If > 2 cm, surgical vs conservative is debated. • In Miñambres et al. meta-analysis, surgical repair was associated with a 2x increased mortality • Meyer et al. case series: surgical repair in critically ill pts is high risk, mortality up to 71%. Miñambres et al. European Journal of Cardio-thoracic Surgery 35 (2009) 1056—1062 Meyer M. Thorac Cardiovasc Surg 2001;49:115—9.
Management of tracheal laceration or rupture • Most recent studies recommend conservative management if • stable pt, no air leakage, no esophageal damage, minimal mediastinal collections, no clinical progression, no sign of infection • Conservative management = intubation with cuff distal to lesion, continuous tracheal aspiration, pleural drain, empiric abx • Surgical repair if unstable, large defect (>4cm), any evidence of mediastinitis Medina et al. J Bras Pneumol. 2009 Aug;35(8):809-13 Miñambres et al. European Journal of Cardio-thoracic Surgery 35 (2009) 1056—1062

In retrospect, had we known what was going on, would probably have at least evaluated for surgical repair earlier. • Small rupture, but distal to ETT and with demonstrated clinical deterioration
