A simple modification of Ciaglia Blue Rhino technique for tracheostomy: using a guidewire dilating forceps for initial dilation.
OBJECTIVE
The potential difficulty in doing initial dilation in the percutaneous dilational tracheostomy (PDT) with the Ciaglia Blue Rhino (CBR) technique has been reported by others and encountered in our clinical practice. To resolve this problem, we developed a modified CBR technique by using a guidewire dilating forceps (GWDF) to facilitate initial dilation. The present before-and-after comparison study aimed to evaluate the clinical benefits of this modified CBR technique.


METHODS
Consecutive 120 patients undergoing CBR technique in the pre-conversion year and 114 patients undergoing GWDF-CBR technique in the post-conversion year were enrolled for analysis. The procedure time and procedure-related complications were compared between these two groups.


RESULTS
The mean procedure time with GWDF-CBR technique was 4.5+/-1.6min, significantly shorter than 5.7+/-3.0min with CBR technique (p<0.001). Only two patients in the GWDF-CBR group required prolonged procedure time (>8min), compared with 14 patients in the CBR group. Thirty three (27.5%) of 120 patients undergoing CBR technique and 15 (13.1%) of 114 patients undergoing GWDF-CBR technique had PDT-related complications (p=0.006). Most of the complications were minor and transient. Only 13 patients in the CBR group and 3 patients in the GWDF-CBR group encountered major complications (10.8% vs 2.6%, p=0.012). Regarding the high-risk patients, 21 (36.2%) of 58 patients in the CBR group and 9 (15.8%) of 57 patients in the GWDF-CBR group had PDT-related complications (p=0.011).


CONCLUSIONS
Pre-dilation with a GWDF in the CBR technique helped to prevent prolonged procedure time and procedure-related complications. We suggest that the bronchoscopy-guided GWDF-CBR serves an easy-to-operate and relatively safe PDT technique for critically ill patients.
