Comparison between single-step and balloon dilatational tracheostomy in intensive care unit: a single-centre, randomized controlled study.
BACKGROUND
Balloon dilatational tracheostomy using the Ciaglia Blue Dolphin device has recently been introduced as a modification of the Ciaglia technique. The aim of this study was to compare the new Dolphin system with the single-step dilatational tracheostomy (Ciaglia Blue Rhino) in intensive care unit (ICU) patients.


METHODS
Consecutive patients admitted to the ICU of the Emergency Department (Careggi Teaching Hospital, Florence, Italy) from January 2009 to October 2009, aged >18 years and with an indication for percutaneous dilatational tracheostomy (PDT), were enrolled. Exclusion criteria were infection/injury/malignancy of the neck, thyroid gland hypertrophy, severe head injury with uncontrolled intracranial hypertension, and coagulopathy. Patients were randomly assigned to undergo PDT using either the Ciaglia Blue Rhino (n=35) or the Ciaglia Blue Dolphin technique (n=35). Groups were compared according to tracheal puncture, tracheal tube placement time, procedure-related complications, and bleeding.


RESULTS
Baseline clinical data were comparable between the two groups. Median procedure time was significantly shorter in the Rhino group compared with the Dolphin group (1.5 vs 4 min, P = 0.035). The presence of limited intra-tracheal bleeding at bronchoscopy examination after 6 h from PDT was more frequent in the Dolphin group than in the Rhino group patients (68.6% vs 34.3%, respectively, P = 0.008). No major bleeding occurred in either group.


CONCLUSIONS
PDT using the Ciaglia Blue Dolphin technique is a feasible and viable option in ICU patients, but the Rhino technique had a shorter execution time and seemed to be associated with fewer tracheal injuries.
