Percutaneous tracheostomy is the mouth opening of the tracheal ostium to the skin by creating an opening in the anterior wall of the trachea using Seldinger methods. This procedure is done using an endotracheal tube (ETT) or a laryngeal mask (LMA). High-frequency jet ventilation (HFJV) commonly used in oropharyngeal surgeries and creates an extra passage for the procedure. The investigators aimed to demonstrate the effective use of HFJV in percutaneous tracheostomy.

Seventy five patients between 18-80 years of age who were hospitalized in intensive care unit were included in the study. The number of patients will be finalized by power analysis. whose written consent cannot be obtained and who undergo surgical tracheostomy for any reason will be excluded from the study. In addition, patients with active infection in the area of the procedure, bleeding diathesis and pathologies that interfere with the procedure in the ultrasonographic evaluation (thyroid diseases, etc.) will be excluded from the study. Patients will be divided into three groups as those using classical ventilation (group 1), HFJV (group 2) and classical laryngeal mask (group 3). Age, gender, height, BMI, ASA scores, presence and type of additional diseases, tracheostomy day, pre- and post-procedure blood gas analysis, duration of procedure, duration of anesthesia, complications during the procedure (bleeding , desaturation, accidental extubation, malposition, bradycardia, hypotension, etc.) will be recorded. Patients will be observed for mortality in the first 30 days after the procedure. Mortality results will be recorded.
