Objective: To assess late complications following
percutaneous tracheostomy using the Griggs technique.
Design: Observational cohort study
Setting: General ICU of a 700-bed district general hospital
in the United Kingdom.
Patients: Twenty-five patients
who underwent Griggs tracheostomy in the ICU and survived for at least
6 months after decannulation.
were invited to attend for assessment by questionnaire and for spiral
CT of the trachea.
Results: Eight patients had
moderate tracheal dilatation, two patients were permanently hoarse,
nine patients had minor voice changes, no patient had tracheal
stenosis, and no patient had a disfiguring scar.
Conclusion: Following Griggs percutaneous tracheostomy, 8
of 25 patients developed moderate tracheal dilatation, and none
developed a tracheal stenosis. The cosmetic result after Griggs
tracheostomy is good, but the number of patients with minor voice
changes is high. A further investigation of long-term outcome following
Griggs tracheostomy is necessary.
