Pre-decannulation flexible bronchoscopy in tracheostomized children.

OBJECTIVES

This study was aimed to evaluate the utility and benefits of flexible fiberoptic bronchoscopy (FFB) prior to tracheostomy decannulation.

METHODS

Besides demographic data, initial cause of tracheostomy, primary diagnosis, pre-tracheostomy and pre-decannulation bronchoscopic findings and duration of tracheostomy were collected from medical charts. The type of active intervention following bronchoscopy and outcome after decannulation were recorded. Departmental decannulation policy and procedure were used in all patients.

RESULTS

Forty-nine tracheostomized patients who underwent decannulation attempt were included. The median age of the children at the time of decannulation was 3 years (range 4 months-16 years). The median duration of tracheostomy was 8 months (range 1-86 months). Prolonged mechanical ventilation was the commonest indication for tracheostomy. There were 45 abnormal findings on FFB in 36 patients. Airway granulation was the commonest abnormality (23/45, 51%). Successful decannulation without any intervention was possible in 23 (46.9%) cases. 12 of these had normal bronchoscopy. Fifteen (30.6%) patients required surgical interventions before attempting decannulation. In five patients decannulation failed, while in six children decannulation was not attempted after FFB.

CONCLUSION

Pre-decannulation flexible fiberoptic bronchoscopy in children with tracheostomy helps in identifying the possible causes of decannulation failure and helps in deciding the appropriate intervention.
