Percutaneous dilatation tracheostomy: which technique is the best for the critically ill patient, and how can we gather further scientific evidence?

Percutaneous dilatation tracheostomy in the intensive care setting presents an increasingly important concept for establishing a large-bore tracheal airway with minimal surgical intervention. Over the last years, different technical solutions have been studied to assess their respective risks and benefits to determine whether one method is actually superior. A recent observational study comparing two such techniques prompted this commentary, which reviews the current literature, comments on study design and suggests interesting topics for future research in this field.
