Successful surgical treatment of a complete traumatic tracheal disruption

Anesthetic Management of a Patient With Tracheal Dehiscence Post-Tracheal Resection Surgery

We present a case of a patient with complete tracheal dehiscence and multiple false passages after recent tracheal resection and anastomosis. Loss of tracheal continuity after disruption of anastomosis with distal stump retraction presents a unique anesthetic challenge given lack of access to the trachea and the need for adequate anesthesia and analgesia for surgical neck dissection. Traditional airway management, including awake fiberoptic intubation, intubation via direct laryngoscopy, needle cricothyrotomy, and awake tracheostomy are not viable options. Using total intravenous anesthesia with spontaneous ventilation, surgeons dissected the neck, retrieved the distal tracheal stump, repaired the trachea, and formalized the tracheostomy. We highlight the importance of recognizing the symptoms of a tracheal rupture, understanding the extreme limitation of securing the airway with traditional techniques, and discuss the alternative techniques including use of extracorporeal membrane oxygenation to avoid airway management. Awareness of increased mortality risk with tracheal reoperation and the significance of close communication between the anesthesiologists, the surgeons, and the patient is necessary for successful management.

Traumatic Tracheal Tear Successfully Treated after Remote Area Retrieval

A 44-year-old man injured in a motor vehicle accident in rural Australia was resuscitated at a local hospital 9 hours later. Bronchoscopy revealed a large tracheal tear. After transfer to the regional cardiothoracic center, surgery was performed under cardiopulmonary bypass 18 hours after the injury was sustained. The patient required surgical tracheostomy as well as ventilatory and inotropic support. There were no postoperative complications and he was discharged after 27 days.

[Successful surgical treatment of tracheal rupture caused by endotracheal intubation]

Rupture of the trachea is a rare complication of endotracheal intubation. The most common cause of the injury is the overinflation of the cuff. The authors present the case of a 45-year-old male in whom a 6 cm long trachea lesion was perceived during the operation due to a meso-hypopharyngeal tumor. Primary intervention resulted in successful reconstruction and full recovery. The case demonstrates the importance of prompt diagnosis and adequate therapy that helped in preventing an assumingly life-long complication or even death.

Posterior tracheal wall laceration after blunt neck trauma in children: a case report and review of the literature

Adults seem to be more vulnerable than children to tracheal lacerations. Tracheal lacerations have been described particularly after surgical procedures and penetrating trauma, but they may also result from minor blunt trauma. We report the case of a 7-year-old boy who sustained a posterior tracheal wall laceration after a direct frontal fall on a wooden strut. We also review the literature on posterior wall tracheal laceration as an isolated feature after blunt cervical trauma in children, the diagnostic features and management options.

Complete cervical tracheal rupture in children after closed trauma

The authors report the case of a 5-year-old boy who received a blow from a heavy metallic bar on the front of the neck and presented with a complete rupture of the cervical trachea. Such a rupture is exceptional in children because of the consistency of the cartilage but can occur when the neck is in extension and the glottis is closed. A rigid endoscopy allowed the rupture to be diagnosed, to restore the airway, to prepare the cervicotomy, and the suturing of the trachea. He presented with a stenosis 50 days after the suturing which was treated by dilatation.

Successful surgical management of complete tracheal disruption due to penetrating injury

Successful management of penetrating injury to the trachea is rare, especially in Japan. A 32-year-old female attempted suicide by stabbing herself in the throat with a knife, and at operation the trachea was found to be completely disrupted. A median sternotomy made possible end-to-end anastomosis of the trachea. All other important organs including the great vessels, esophagus, and lungs were intact, but the pleura was open on the right side. The patient was managed under heavy sedation and with controlled ventilation for more than a week postoperatively, because of her suspected mental condition. She was extubated on postoperative day 13 and transferred to a mental hospital on day 16. We concluded that early diagnosis and surgical repair were important for the successful management of this patient with tracheal disruption.

Indications for surgery in tracheobronchial ruptures

OBJECTIVE

Ruptures of the tracheobronchial tree present a life-threatening situation. Nevertheless, therapy is still controversial. Though conservative treatment by antibiotics and intubation with the cuff inflated distal to the tear is favored by some authors, surgical repair is unavoidable in many cases.

METHODS

We present a series of 31 patients (mean age 43.6 years, range 8--72 years) with iatrogenous or post-traumatic tracheobronchial ruptures treated since 1975. Fifteen ruptures were longitudinal tears of the trachea, not extending lower than a distance of 3 cm from the bifurcation, 11 involved the bifurcation and/or the main bronchi. The total length of the longitudinal tears ranged from 2 to 12 cm, five were transverse near complete abruptions of the trachea or main bronchi. Involvement of the full thickness of the wall with free view into the pleural space or to the esophageal wall was present in 29 cases. Twenty-nine out of the 31 patients underwent surgical repair and two were treated conservatively. The length and depth of the lesion, the degree of subcutaneous emphysema, pneumothorax and/or pneumomediastinum as well as clinical signs suggesting incipient mediastinitis were considered when making the decision for surgery.

RESULTS

Twenty-five out of the 29 patients experienced an uneventful recovery. Four patients died of sepsis unrelated to the tracheobronchial trauma. One of the two patients who underwent conservative therapy also recovered uneventfully. The other one died because of multi-organ failure due to underlying myocardial infarction.

CONCLUSIONS

Conveniently localized short lacerations, especially if they do not involve the whole thickness of the tracheal wall, can be treated with antibiotics and intubation with the cuff inflated distal to the tear, avoiding high intra-bronchial pressures also after eventual extubation. In all other cases surgical repair is to be preferred.

Acute injuries of the trachea and major bronchi: importance of early diagnosis

BACKGROUND

Tracheobronchial injuries are encountered with increasing frequency because of improvements in prehospital care and early initiation of the Advanced Trauma Life Support protocol. We review our experience with these injuries with the hypothesis that the leading determinant of patient outcome is the time interval to diagnosis.

METHODS

Patients with tracheobronchial injury were identified from the registry of our level 1 trauma center during a 10-year period ending December 1997. Clinical presentation, diagnostic evaluation, surgical management, and outcome were reviewed.

RESULTS

Twenty patients with ten cervical tracheal injuries and ten intrathoracic tracheobronchial injuries were treated. The mechanism of injury involved blunt trauma in 11 and penetrating trauma in 9. All patients underwent surgical debridement and primary repair. Patients with isolated airway injuries were discharged home after a mean hospital stay of 6 days and had no early complications. Three patients had delayed diagnosis (> 24 hours), and all sustained complications including death (1 patient) and multiorgan system failure (2 patients). The overall mortality rate was 15%.

CONCLUSIONS

Operative management of tracheobronchial injuries can be achieved with acceptable mortality. Independent of mechanism or anatomic location of injury, delay in diagnosis is the single most important factor influencing outcome. Early recognition of tracheobronchial injury and expedient institution of appropriate surgical intervention are essential in these potentially lethal injuries.

Tracheobronchial injuries after blunt chest trauma in children--hidden pathology

BACKGROUND

Blunt thoracic injuries in children are unique because the pliability of the chest wall allows transmission of massive external force directly into the mediastinum. Children presenting after blunt chest trauma may have complete disruption of the airway with little external sign of injury. Without prompt diagnosis and appropriate treatment, the risk for progressive respiratory failure is high.

METHODS

Four children with tracheobronchial injuries were referred to a pediatric trauma center from 1994 to 1997. All children, age 18 months to 13 years, suffered unusual crush injuries. All diagnoses were based on unresolved pneumothorax or pneumomediastinum.

RESULTS

Bronchoscopy identified the location of injury as posterior trachea (n = 1) and right mainstem bronchus (n = 2). A tertiary bronchial injury (n = 1) was missed by initial tracheogram and subsequent bronchoscopy but identified during surgical exploration. All children survived after thoracotomy and primary repair of the injury.

CONCLUSIONS

Tracheobronchial disruption is a rare, life-threatening injury. Suspicion should be high when pneumomediastinum and pneumothorax are refractory to adequate pleural drainage. Flexible bronchoscopy with intubation distal to the injury may be necessary to prevent loss of the airway. Advance preparation should include setups for bronchoscopy, thoracotomy, and cardiopulmonary bypass. Patient survival depends on preparation and prompt surgical intervention.
