What are the contraindications of a tracheostomy?

As tracheostomy is a life saving procedure, there are no absolute contraindications to tracheostomy.

However some relative contraindications are:

  • In patients with obstructive carcinoma of the larynx, once tracheostomy is done there are increased chances of stromal recurrence.
  • Bleeding disorders: They can give troublesome bleeding from the tracheostomy site.
  • If a foreign body is lodged below the level of the tracheostomy site, it would not help in relieving the stridor unless emergency bronchoscopy is done.

It must be understood that the above should not be considered in cases of an emergency.
