In this study, our primary goal is to compare whether there is any difference in the complication of using pro-seal laryngeal mask or intubation tube in bronchoscopy-guided percutaneous dilation tracheostomy procedure. Our secondary goal is to compare in terms of processing time.

Following the approval of Muğla Sıtkı Koçman University Clinical Research Ethics Committee, 61 cases over the age of 18 who were scheduled for elective percutaneous dilatation tracheostomy in intensive care units were included in the study.

Elective percutaneous dilatation tracheostomy cases were randomly divided into two groups. Group 1 was determined as endotracheal tube and group 2 as pro-seal laryngeal mask group.

In the endotracheal tube group, which is a conventional method, after entering the trachea with percutaneous technique, the intubation tube was removed before dilatation and percutaneous dilatation tracheostomy was performed with the Seldinger method.

In the pro-seal laryngeal mask group, the fiberoptic bronchoscope was advanced with a pro-seal laryngeal mask, and after the correct position was achieved, percutaneous dilatation tracheostomy was performed using the Seldinger Method.

Arterial blood pressure, oxygen saturation, heart rate, arterial blood gas, mechanical ventilation mode, positive end expiratory pressure and mean airway pressure values were recorded before and 30 minutes after the procedure.

The time until the end of the procedure and complications were determined.

Inclusion Criteria:hospitalized in intensive care units of our hospital and planned for elective percutaneous dilatation tracheostomy were included in the study.
