OBJECTIVES: Endotracheal tube (ETT) displacement occurs by improper fixation. To fix an ETT, many types of fixation tools are employed. Thomas tube holder is one of the fixation tools widely used in many countries. This study aims to compare the ETT fixation using the Thomas tube holder with the conventional method (adhesive tape) in a mannequin model.

METHODS: The fixation tools were random, using the box of six randomizes to Thomas tube holder and conventional method. After fixation, the mannequin model was being logged roll, chest compression by automated chest compression machine, and transported by the paramedic. The time to ETT fixation and displacements were recorded.

RESULTS: The mean time (standard deviation) to fixate an ETT was shorter (33.0 s [7.3]) with a Thomas tube holder compared to adhesive tape (52.6 s [7.3], P < 0.001). The number and proportion of the ETT displacements were significantly less with Thomas tube holder compared to adhesive tape during log roll (16, 35.6% vs. 29, 64.4%, P = 0.011), chest compression with automated machine (23, 51.1% vs. 37, 82.2%, P = 0.003), and transport (26, 57.8% vs. 40, 88.9%, P = 0.002).

CONCLUSION: The Thomas tube holder is more effective than adhesive tape in preventing ETT displacement in a mannequin subjected to log roll, chest compressions, and transportation.
