Percutaneous dilational tracheostomy: a comparison of single- versus multiple-dilator techniques

Area of Science:

• Critical Care Medicine
• Surgical Procedures

Background:

• Percutaneous dilational tracheostomy (PDT) is a common procedure in intensive care units.
• Both single- and multiple-dilator techniques exist for PDT, with varying procedural times.

Purpose of the Study:

• To compare the safety and efficacy of single- versus multiple-dilator techniques for PDT.
• To evaluate procedural time and complication rates between the two PDT methods.

Main Methods:

• Prospective randomized trial involving 50 patients requiring tracheostomy.
• Patients were randomized to receive PDT using either the single- or multiple-dilator technique.
• Procedures were conducted in intensive care units at a level 1 trauma center.

Main Results:

• The single-dilator technique was significantly faster (6:01 ± 3:03 min) than the multiple-dilator technique (10:01 ± 4:26 min) (p < .0006).
• No statistically significant differences in complication rates were observed between the two techniques.
• No major complications were reported for either the single- or multiple-dilator PDT methods.

Conclusions:

• The single-dilator PDT technique is a safe and effective alternative.
• This method is more rapidly performed and potentially cost-effective for bedside tracheostomy.
• Single-dilator PDT is suitable for airway control and prolonged mechanical ventilation support.
