Common symptoms of acute airway obstruction • Voice change • Dyspnea • Local pain • Cough
Common findings of acute airway obstruction • Stridor • Hoarseness • Retraction (intercostal- suprasternal-supraclavicular) • Drooling - bleeding - emphysema
Management of impaired airway • Simplest adequate form of control should be selected • Lower level • Other medical problems
Indications for tracheostomy • Prolonged intubation • Ventilation support • Manage bronchopulmonary secretion • Upper airway obstruction • Obstructive sleep apnea • Bilateral vocal cord paralysis • Inability to intubate • Major head & neck surgery or trauma
Tracheostomy Advantages • lower risk of laryngotracheal injury • improved comfort/mobility • improve airway stabilization • allows for oral nutrition • improved secretion clearance
Surgical anatomy • Sternal notch • Thyroid cartilage • Cricoid cartilage - cricothyroid membrane - innominate artery - thyroid gland (isthmus) - recurrent laryngeal nerve
Anatomy • Venous supply • Superior and middle thyroid v. drain into the IJ • Inferior thyroid v. drains into the brachiocephalic trunk
Anatomy • Anatomy variant: thyroid ima artery, in 1.5% to 12%, in front of the trachea.
Tracheotomy timing • Emergent (slash trach) • Urgent (awake) • Elective
Surgical technique • Optimally under general anesthesia • Incision between sternal notch and cricoid • Dissection in a vertical plane • Thyroid isthmus (third and fourth ring) • Entrance into trachea • Tracheotomy tube insertion
Immediate complications • Hemorrhage • False route • Electrocautery fire • Injury to adjacent structures
Intermediate complications • Hemorrhage [most common ] • Infection • Subcutaneous emphysema • Pneumomediastinum • Pneumothorax [most common in infant ] • Obstruction of tacheotomy tube • Displacement of tube
Late complications • Hemorrhage • Tracheoesophageal fistula • Tracheal stenosis • Tracheocutaneous fistula
