Brief Summary

Percutaneous dilatational tracheostomy (PDT) is a commonly performed procedure in intensive care units for patients requiring prolonged mechanical ventilation. Fiberoptic bronchoscopy (FOB) and ultrasonography (USG) are frequently used to guide PDT in order to improve procedural safety. However, the effects of these guidance techniques on ventilation parameters during the procedure remain unclear. This retrospective observational study aims to compare the effects of FOB-guided and USG-guided percutaneous dilatational tracheostomy on ventilation parameters in mechanically ventilated adult intensive care unit patients. Changes in arterial blood gas parameters and ventilator settings during and after the procedure will be evaluated. The findings of this study may help clinicians better understand the physiological effects of different PDT guidance techniques and support informed decision-making in clinical practice.
