Visual-Guided Transillumination Method for Accurate Percutaneous Tracheal Tube Placement
Diane C. McLaughlin, Michael P. Schaller, Julian Bösel, Mohamad ChmayssaniBACKGROUND:
Percutaneous tracheostomy (PT) is generally considered a safe procedure, but complications such as malpositioning, bleeding, and tracheal ring rupture remain concerns, particularly during initial needle insertion. This study investigates the feasibility, ease of use, and safety of a novel device and technique for bedside PT, named the Illuminated Tracheal Alignment Guide (iTAG).
METHODS:
An interventional pilot study evaluated the feasibility and safety of the iTAG device and method. The study was approved by our local institutional review board and a Food and Drug Administration waiver was granted for use of our device. Patients in a neurocritical care unit requiring tracheostomy were screened and consented for inclusion. Exclusion criteria included significant vascular overlap and specific ventilator settings. The iTAG method involves a laser light source and a needle guide with a hard stop, used in conjunction with standard PT equipment. Data on demographics, procedure details, and early complications were collected and compared with historical control data from patients who underwent standard tracheostomy (ST).
RESULTS:
From January 2023 to July 2024, 30 patients underwent PT using the iTAG device. The mean time from intubation to tracheostomy was 15.53 days, with a mean ICU length of stay of 31.14 days. The iTAG group experienced significantly fewer early complications compared with the historical ST control group, including reduced hemorrhage, and there were no instances of tracheal ring fracture, posterior wall injury, or pneumothorax. The iTAG method allowed for safe PT in all patients.
CONCLUSIONS:
The iTAG device enhances the safety and efficacy of PT by providing precise visualization and limiting needle penetration, reducing early complications. Its use expands patient candidacy for PT and offers a valuable tool for training less-experienced practitioners. Further research with larger cohorts and randomized controlled trials is needed to confirm these findings and establish the iTAG method as a standard of care for PT.
