Percutaneous tracheostomy by forceps dilation: report of 162 cases.

A prospective, observational clinical study evaluated the safety of percutaneous single-step dilatational tracheostomy over a 43-month period. One hundred and sixty-two patients were deemed suitable for the procedure. The mean duration of tracheal intubation prior to tracheostomy was 6 days. The mean duration of the procedure was 9.3 min. Intra-operative complications occurred in 27 patients (16.6%), most of which were minor technical difficulties without morbidity. Postoperative complications, some of which were associated with morbidity, occurred in 16 patients. There were two deaths secondary to premature decannulation, one case of severe bleeding and five pneumothoraces. Long-term complications were assessed in 81 patients; there were four tracheal stenoses requiring surgery or laser therapy and seven patients with granulation tissue at the stoma site which did not require treatment. Forceps dilatational percutaneous tracheostomy appeared to be a convenient bedside procedure. However, complications do occur and further studies should address late sequellae, such as tracheal stenosis.
