We developed a portable, relatively low cost device that functions as an aid to Endotracheal Tube (ETT)intubations and ETT position confirmation. The device has no sterility issues; can be re-used in the same patient; and creates a permanent recording of its findings. Most, if not all, available devices cannot offer all this. The device is a battery operated, handheld, digital recording (still or video) device that attaches to a disposable stylet which has a digital chip embedded in the distal end. The chip transmits images to the recorder and small digital screen. It allows direct visualization and digital recordings during ETT intubation, and confirmation of ETT placement.
15 trainees in the Internal Medicine Residency at the Mount Vernon Hospital (5 PGY1s, 5 PGY2s, 5 PGY3s,) working with intubation mannequins were given an instructional session. Following the instruction they were first were asked to attempt intubation using the device, including videoing. Secondly they were asked to confirm or refute proper position of a previously inserted ETT, also with video recording.
Out of 15 trainees:15 visualized the vocal cords(100%); 15 successfully intubated(100%); 15 confirmed the ETT position(100%); 15 produced a video recording of the intubation (100%); 15 produced a recording of the ETT position (trachea or esophagus) (100%).
In this relatively untrained group the device allowed direct visualization during ETT intubation and ETT placement confirmation while providing a digital record.
The relatively low cost, portability, in addition to other features (waterproof, shockproof, rechargeable, enhanced digital image screen, and others) will likely improve airway management, including the difficult airway, in the future, and may lead to enhanced standards of care. If an untrained group could utilize the device successfully, then trained groups would undoubtedly benefit as well. Further studies are clearly needed.
