Objective To evaluate the risk factors of tracheal ring fracture and whether previous tracheal ring flaccidity predisposes to it in consecutive, mechanically ventilated, intensive care unit patients undergoing different percutaneous dilatational tracheostomy procedures (Ciaglia Blue Rhino, PercuTwist, and Ciaglia BlueDolphin). Design Single-center retrospective study performed between November 2006 and July 2013. Setting Single-center university hospital. Participants Two hundred nineteen consecutive intensive care unit patients. Interventions Video bronchoscopic percutaneous dilatational tracheostomies using different techniques, including Ciaglia Blue Rhino, PercuTwist, and Ciaglia BlueDolphin, were performed consecutively. During the procedure, the tracheal wall response to the routine external palpation was evaluated endoscopically to find the interanular space. An abnormal change in the tracheal ring shape (fingerprint) with anterior airway wall collapse was diagnosed as tracheal flaccidity. Measurements and Main Results Tracheal ring fracture occurred in 21 patients (9.6%). The proportion of tracheal ruptures was 16 (76.2%) after PercuTwist, 3 (14.3%) after Ciaglia Blue Dolphin, and 2 (9.5%) after the Blue Rhino technique. Significant risk factors for tracheal rupture were PercuTwist procedure (p = 0.02), tracheal flaccidity (p = 0.0001), and a period of intubation before a percutaneous dilatational tracheostomy procedure>14 days (p = 0.01). Conclusions In addition to the PercuTwist technique and intubation>14 days before tracheostomy, tracheal flaccidity was a significant risk factor for tracheal ring fracture. In the presence of this finding, a less traumatic tracheostomy procedure should be applied.
