Clinical features and management of closed injury of the cervical trachea due to blunt trauma

Right trace wrong place: a normal capnography trace despite the tip of the tracheal tube existing outside the airway

Head and neck trauma can result in difficult airway management. A 25-year-old male required emergency tracheal intubation on arrival to the emergency department following a motorbike accident. Despite the presence of a normal capnography a computed tomography scan demonstrated a tracheal opening, an extra-tracheal position of the distal end of the tracheal tube, and extensive subcutaneous emphysema. The tube was re-directed into the trachea and the tracheal injury was surgically repaired. This case highlights that the presence of a normal capnograph does not necessarily mean that the distal end of the tracheal tube resides within the airway.

Airway management of major blunt tracheal and esophageal injury: A case report

Trans-sectional injuries of trachea are quite rare and can be extremely challenging for anesthesiologists to deal with. About 25% of post-traumatic deaths are due to thoracic traumas in which blunt injuries take a rather small place within and the resultant damage of respiratory tract is quite rare with an incidence of 0.5-2%. A recent review from a single trauma center revealed an incidence of 0.4% for tracheobronchial injury (TBI) due to blunt thoracic injuries. Most of the patients having tracheal transection lose their lives on the field due to loss of airway. Patients mostly present with a large spectrum of clinical features varying from hoarseness to respiratory collapse; though subcutaneous emphysema is the most common presenting sign which should remind possible TBI. Emergent surgery is preferred seldomly; such in cases of partial damage or because of late diagnosis, due to favorable outcome of conservative approach. Herein, we report the management of a case on TBI due to blunt thoracic trauma, experiencing difficult ventilation despite tracheal intubation. Fiber-optic bronchoscope (FOB) seems obligatory to visualize site and severity of injury and to ensure safe airway during procedures such as the neck exploration, primary end-to-end anastomosis of the trachea, tracheostomy, diversion pharyngostomy, and feeding jejunostomy.

Intensive Care Unit Management of a Patient with Tracheal Rent Repair Following Laryngopharyngoesophagectomy

Tracheal injuries are one of the potentially fatal complications following laryngopharyngeal and esophageal surgeries. The patient developed tracheal rent during laryngopharyngoesophagectomy. The injury was diagnosed intraoperative and repaired. However, it did not heal, and the patient developed tracheopleural fistula. Right thoracotomy and latissimus dorsi flap was done under general anesthesia. Postsurgery, the patient was shifted to intensive care unit (ICU), where he developed respiratory distress not improving, with increasing oxygen flows. To avoid damage to the repair, under bronchoscopic guidance bilateral selective mainstem bronchial intubations were done using cuffed 5.0 mm regular endotracheal tubes (ETTs), and ventilation was supported on pressure control ventilation mode. The ventilator support was weaned off to pressure support ventilation mode on postoperative day (POD) 1. On POD2, ETTs were removed under bronchoscopic guidance and were replaced by 7 mm ID long and adjustable flange tracheostomy tube with the tip just above the carina. The cuff was kept deflated, and oxygen with the high flow was provided through a tracheostomy. The high flow was weaned off after 5 days. Later, the patient was managed conservatively by regular chest physiotherapy, antibiotics, bronchoscopic pulmonary toileting, nebulizations, and appropriate antimicrobial therapy. Patient was discharged in stable condition from ICU and hospital.

Prehospital tracheotomy in a case of avulsion of the larynx with a comminuted fracture of the jawbone

Emergency physicians in the field are sometimes confronted with cases wherein patients cannot be intubated and ventilated. In some cases, cricothyrotomy, the method of choice for securing an emergency airway, may not have a successful outcome. We report a rare case of a 35-yearold male patient with avulsion of the larynx and a comminuted fracture of the jawbone, due to entrapment in a dung excavator. Prehospital tracheotomy was successfully performed. In cases with crush injuries to the larynx, anatomic structures, including the ligamentum conicum, are destroyed. In addition, massive subcutaneous emphysema blurs the anatomical key structures; hence, only a tracheotomy can prevent a lethal outcome.

Blunt Trauma Neck with Complete Tracheal Transection - A Diagnostic and Therapeutic Challenge to the Trauma Team

Survival following trachea-esophageal transection is uncommon. Establishing a secure airway has the highest priority in trauma management. Airway management is a unique and a defining element to the specialty of emergency medicine. There is no doubt regarding the significance of establishing a patent airway in the critically ill patient in the emergency department. Cannot intubate and cannot ventilate situation is a nightmare to all emergency physicians. The most important take-home message from this case report is that every Emergency physician should have the ability to predict “difficult airway” and recognize “failed airway” very early and be skilled in performing rescue techniques when routine oral-tracheal intubation fails. Any delay at any step in the “failed airway” management algorithm may not save the critically ill dying patient. Here, we report a case of blunt trauma following high-velocity road traffic accident, presenting in the peri-arrest state, in whom we noticed “failed airway” which turned out to be due to complete tracheal transection. In our patient, although we had secured the airway immediately, he had already sustained hypoxic brain damage. This scenario emphasizes the importance of prehospital care in developing countries.

Tracheobronchial Injury caused by Blunt Trauma: Case Report and Review of Literature

Tracheobronchial injuries are rare cases requiring skillful airway management. We report a challenging case of tracheobronchial injury in a young adult who was run over by a tractor and was referred to us from a peripheral hospital with endotracheal tube in situ. He was severely hypoxaemic on initial presentation. Diagnostic work up showed high suspicion for right bronchial transection along with left lung upper lobe contusion. Due to deteriorating clinical condition of the patient and despite immediate unavailability of fibreoptic bronchoscope, patient was immediately taken up for right posterolateral thoracotomy and double lumen tube was inserted. The position of the tube was confirmed clinically. As soon as the fibreoptic bronchoscope arrived, it was again used to confirm the position of double lumen tube. Patient's clinical condition improved after repair of the injured right bronchus and he was later extubated the next day.

Traumatic tracheal injury in children: a case series supporting conservative management

OBJECTIVES

Injuries to the tracheobronchial region are rare, but have the potential for rapid progression and can become life-threatening. Etiologies of non-penetrating tracheobronchial injuries include blunt cervical trauma, endotracheal intubation, and other iatrogenic causes. Several options for treatment ranging from conservative to surgical exist, but no single treatment has been implemented with consensus. While early surgical repair was once considered the cornerstone of therapy, evidence supporting conservative treatment continues to gain strength.

METHODS

All pediatric patients who suffered from non-penetrating injuries to the tracheobronchial tree who were treated by the Otolaryngology Service at a tertiary children's hospital from May 2012 through March 2014 were recorded. A total of 8 patients were identified. The cases were collected from the patients treated by the Otolaryngology Department based on retrospective review. The available electronic medical records were reviewed for each patient. Data including type of injury, endoscopic assessment of injury, treatment received, and follow-up were collected.

RESULTS

The ages ranged from 2 to 15 years old, with a mean of 9.25 years old. Six of the eight patients had injuries related to endotracheal intubation. Each patient was taken to the operating suite for diagnostic direct laryngoscopy and bronchoscopy, and treated with initial conservative management. All but one of the patients was treated with endotracheal intubation, and the average length of intubation was 11.71 days. All of the injuries healed spontaneously without requiring initial open surgery. Five patients (62.5%) developed some degree of tracheal stenosis. Three patients (37.5%) required further surgery; one received a tracheostomy and two patients required balloon dilation.

CONCLUSIONS

This case series is the largest to date documenting the outcomes of conservative treatment of non-penetrating traumatic tracheal injuries in children. By using initial conservative therapy, we were able to avoid open surgical procedures in many of our patients. We believe that this case series provides further support for conservative management for children with tracheobronchial injuries.
