Trial Outcomes & Findings for Endotracheal Tube Holder and Bite Guard Research (NCT NCT02347488)

NCT ID: NCT02347488

Last Updated: 2017-04-17

Results Overview

The ability of the securing device to resist endotracheal tube dislodgement under axial strain for patients in the supine position was measured. The endotracheal tube, once secured with either tape or the Haider airway device, encountered an axial force to simulate the endotracheal tube being pulled from the mouth. The force increased over approximately 5 seconds until the target of 15 N was reached or until the principal investigator deemed that the force be aborted to prevent possible tracheal extubation. The change in position, measured in cm, was recorded.

Measure
Tape, Followed by ETT Holder and Bite Guard
Tape: Surgery patients had endotracheal tubes secured with adhesive tape, as the current clinical procedure; change in ETT tip position caused by traction up to 15N measured prior to re-securing the ETT with the Haider device. Haider ETT Tube Holder and Bite Guard: Surgery patients then had endotracheal tubes secured with a novel combined endotracheal tube holder and bite guard; change in ETT tip position caused by traction up to 15N measured prior to surgery.

Measure
Adhesive Tape
n=30 Participants
Participants had endotracheal tubes secured with tape prior to having surgery, which is the current standard of care. Following the traction test and measurement of ETT tip position displacement, endotracheal tubes were re-secured with a combined Haider ETT Tube Holder and Bite Guard.

Change in ETT Position
3.4 centimeters
Standard Deviation 1.8
0.3 centimeters
Standard Deviation 0.6

SECONDARY outcome

Timeframe: Immediately after surgery and 1-3 days following surgery, before discharge.

Population: 29 patients returned the survey (one patient was aphasic post-op and could not compete the survey)

The patients were examined after surgery (both immediately after surgery and at the end of the recovery room period) to determine if the patient suffered any irritation or minor injury to the face and oral structures. The patients were asked to fill out a questionnaire after recovery with questions about their overall experience with specific relation to any irritation and/or minor trauma to their face, oral structures, throat, jaw, and temporomandibular joint.

Tape: Surgery patients had endotracheal tubes secured with adhesive tape, as the current clinical procedure; change in ETT tip position caused by traction up to 15N measured prior to re-securing the ETT with the Haider device. Haider ETT Tube Holder and Bite Guard: Surgery patients then had endotracheal tubes secured with a novel combined endotracheal tube holder and bite guard; change in ETT tip position caused by traction up to 15N measured prior to surgery. Adverse events were not reported "per arm" because surgery patients were assessed for adverse events after experiencing both methods.
