Comparison between the Percutwist and the Ciaglia percutaneous tracheotomy techniques.

A prospective study was designed to compare two single-dilator percutaneous tracheotomy techniques, the Ciaglia BlueRhino and the Percutwist technique. One hundred and ninety adult patients were included, 166 with the BlueRhino, a conical shaped, flexible rubber dilator, and 24 with the Percutwist, a screw like dilating device. The procedure was performed under fiberscopy in the intensive care unit (ICU). Age, body mass index (BMI), indication for tracheotomy, surgical landmarks, duration of the procedure and surgical complications were recorded. Median age and indications were similar for the two groups. Dilation was successful in all patients. The mean time for surgery was shorter with the Ciaglia technique: 8 +/- 3 versus 12 +/- 5 min with the Percutwist technique (P = 0.004). There was no significant difference related to weight, BMI, duration of tracheotomy and complications between both groups. One posterior tracheal wall puncture was observed with the Ciaglia technique and four with the Percutwist technique. No serious complications were noted with either technique. The Percutwist technique represents an alternative to the more established Ciaglia BlueRhino technique. The Ciaglia technique is a safe and more rapid procedure for bedside tracheotomy
