Review Meta AnalysisSingle dilator vs. guide wire dilating forceps tracheostomy: a meta-analysis of randomised trials.
Single dilator technique (SDT) and guide wire dilating forceps (GWDF) are the two most commonly used techniques of percutaneous dilatational tracheostomy (PDT) in critically ill adult patients. We performed a meta-analysis of randomised, controlled trials comparing intraoperative, mid-term and late complications of these two techniques. ⋯ GWDF technique is associated with a higher incidence of intraprocedural bleeding and of technical difficulties in completing the procedure (difficult cannula insertions/difficult dilations or failures) compared with the SDT technique. No differences were identified in mid-term and long-term complications. Further studies comparing SDT and GWDF in the general population and in subgroups of high-risk patients (like obese or hypoxaemic patients) are warranted.
