Is HFJV a better alternative ventilation technique for percutaneous dilatational tracheostomy? A randomised trial

High-frequency jet ventilation (HFJV) has been used for the treatment of tracheal lesions, airway surgery, and treatment of secondary lesions after tracheostomy for many years however, reports on the use of HFJV during percutaneous dilatational tracheostomy (PDT) are limited. This study compares the use of traditional method, ventilation with laryngeal mask airway (LMA), and HFJV through endotracheal tube (ETT) with respect to the duration of PDT procedure and complications.Seventy-five patients were randomized into one of the three groups with computer-generated random numbers: Group ETT (N.=25), group LMA (N.=25), and group HFJV (n=25). Demographic data, duration of PDT, complications such as ETT cuff puncture and tube transaction, accidental extubation, difficult cannula insertion, bleeding, desaturation during the procedure, arterial blood gases immediately before and after the procedure have been recorded.Mean time for successful PDT in group ETT was 5.9±1.35 minutes, in group LMA 4.96±0.78 minutes, and 3.88±0.78 minutes in group HFJV. PDT duration was shorter in the LMA group than in the ETT group (P<0.05). In the HFJV group, the PDT duration was shorter than the LMA group (P<0.05) and the ETT group (P<0.001). In terms of the total number of complications, significantly fewer complications were observed in the HFJV group compared with group ETT and group LMA.HFJV may be a more effective alternative method for airway management during PDT, facilitating and reducing the duration of the intervention.
