Final answer:
Emergency tracheostomy reinsertion is contraindicated when there is an obstruction in the trachea or lower respiratory tract that cannot be managed with a tracheostomy. Options like endotracheal intubation may be utilized during general anesthesia due to diminished muscle control. Alternative airway management techniques may be required to address the obstruction.
Step-by-step explanation:
The contraindication to emergency tracheostomy reinsertion typically relates to the presence of a complete airway obstruction that cannot be bypassed or controlled through a tracheostomy. Such obstructions could be a result of an aspirated object or the development of a pseudomembrane, as seen in severe cases of infections like diphtheria. In situations where the obstruction is in the trachea or lower in the respiratory tract, the Heimlich maneuver may be required to dislodge the obstruction and allow for reinsertion of the tracheostomy tube.
When an emergency tracheostomy reinsertion is contraindicated, alternative methods such as endotracheal intubation, or surgical intervention may be necessary to secure the airway. During general anesthesia, for instance, endotracheal intubation is preferred over tracheostomy to maintain a patent airway while the patient's protective reflexes and muscle tone are diminished. The intubated tube is removed as the patient regains muscular control over breathing post-anesthesia.
