Percutaneous versus open tracheostomy: a retrospective cohort outcome study.

Percutaneous tracheostomy has been advocated as a faster, safer, and less invasive method of placing tracheostomy tubes in ventilated patients. To compare outcome differences, as measured by complication rates, between percutaneous and open tracheostomy, a retrospective cohort study was performed. All procedures were performed in the intensive care unit of a university-affiliated hospital. The minor complication rates did not differ significantly between percutaneous and open tracheostomy (12/31 vs. 12/29, respectively; p > 0.05), nor did there appear to be a difference in rates of major complications between the two groups (7/31 vs. 5/29; p > 0.05). This study identified a trend towards an increased risk of delayed airway loss in the percutaneous tracheostomy group.
