CASE
A 66-year-old male was admitted to our hospital with severe trauma who underwent tracheostomy using a 7.5-mm Cuffed Tracheostomy Tube. He underwent first tracheostomy tube change 14 days later. The authors named this method “Foley Catheter-Guided Tracheostomy Tube Change.” The details are as follows:
The “Foley Catheter-Guided Tracheostomy Tube Change” Method
1. Preparation (Fig. 1)
1) Prepare a new tracheostomy tube, 10-cc syringe, scissors, gauze, and lubricant.
2) Prepare a Foley catheter of appropriate thickness to insert in the tracheostomy tube.
For example:
7.5-mm tracheostomy tube using ≥20-Fr Foley catheter 7.0-mm tracheostomy tube ≥18-Fr Foley catheter
3) To use the Foley catheter as a guide, cut off the thick part at the backside with scissors.
4) Pre-lubricate the end of the tracheostomy tube and the Foley catheter.
2. Foley catheter-guided tracheostomy tube removal (Fig. 2)
1) Perform deballooning of the patient’s tracheostomy tube and release the fixation.
2) Separate the ventilator circuit from the tracheostomy tube.
3) Suction the tracheal and oral secretions.
4) Remove the tracheostomy tube while keeping the scissored Foley catheter in the tracheostomy tube. (In most cases, a large amount of secretion is released.)
3. Foley catheter-guided tracheostomy tube insertion (Fig. 3)
1) Be extra careful not to let the Foley catheter come out.
2) Hold the back part with gauze so that the whole of Foley catheter does not enter into the tract.
3) Use the Foley catheter as a guide, carefully insert the tracheostomy tube to be replaced. (Because this is the first tracheostomy tube change, some resistance may be felt in the tract.)
4) Balloon and fix the tracheostomy tube.
5) Connect the ventilator and check the breath sounds with the stethoscope. (Make sure no other problems occur.)
DISCUSSION
Data on routine tracheostomy tube change and its optimal timing are limited. Thus, the technique ensuring its safe performance is not clear. Fisher et al. [
1] reported that the early group who underwent the first tracheostomy tube change within 7 days tolerated faster than the late group for speaking valve and oral intake. In addition, the short respiratory care unit and hospital stays are advantageous. Yaremchuk [
2] reported that the tracheostomy tube was replaced every 2 weeks to prevent surgical intervention secondary to granulation tissue. White et al. [
3] reported that performing the first tracheostomy tube change in the 1–2 weeks after tracheostomy was risky. They emphasized that it should be performed by a skilled operator in a safe environment. Tabaee et al. [
4] conducted an otolaryngology training program for chief residents. During the first tracheostomy tube change, 42% of patients experienced loss of airway and 15% died.
To reduce these risks, a tracheostomy tube changer method, using a 20-cm short suction catheter and guide-wire method, a whistle tip catheter method, a thin endotracheal tube in the tracheostomy tube method, and a sterile 8-in. and 16-G catheter method were used [
