Long-term outcomes following percutaneous tracheostomy using the Griggs technique

Percutaneous tracheostomy is commonly performed in the intensive care unit. This study assesses the long-term outcomes following percutaneous tracheostomy using the Griggs technique. We carried out a prospective observational cohort study. Two hundred and eight patients who had undergone percutaneous tracheostomy between 1 September 1996 and 31 July 2000 and who were alive at least six months following the procedure, were included in the study. Median follow-up was at 30 months. All patients were sent questionnaires regarding relevant symptoms. One hundred and six (51%) responded and were invited for further follow-up. Forty-three (20.6%) patients underwent scar evaluation by the investigators and 41/208 (19.7%) underwent spirometry. Of the responders, 38% complained of some degree of voice change and 12% complained of ongoing severe cough. Thirty-one per cent complained of shortness of breath, with more than half of these having concomitant heart or lung disease, which may explain this. Eighty-one per cent of patients had minimally visible or a visible but neat scar. Eight patients (8/41 (19.5%)) had some evidence of upper airway obstruction on spirometry, but only 2/41 (5% of patients) were symptomatic (stridor or shortness of breath). We conclude that percutaneous tracheostomy using the Griggs technique has an acceptable long-term complication rate.
