Abstract :
Background: The tracheal detecting-bulb (TDB) is a diagnostic tool for confirmation of tracheal intubation. Capnography is the accepted standard for such confirmation. The purpose of this investigation was to determine whether results using the TDB and capnography agree.
Methods: Four hundred patients were divided into three separate studies. In study 1, with 200 consecutive patients, tracheal intubation was performed and tested with the TDB followed by capnography. In study 2, 100 patients had the esophagus intentionally intubated, and confirmation was tested similarly. The tube was then removed and the trachea intubated, and testing followed. Study 3 involved 100 patients and used a double-blind, randomized design. The tube was intentionally inserted into either the esophagus (n = 42) or trachea (n = 58), and testing followed.
Results: In study 1, the rhythmic fill-collapse of TDB was shown in 173 patients, and always agreed with capnography; In 27 instances, the latex bulb of TDB remained collapse or only be filled, and there was no capnogram, it indicating esophageal intubation. In study 2 and 3, regardless of esophageal or tracheal intubation, agreement between TDB and capnogram was 100%. In the 400 patients studied, results from the TDB and capnogram always agreed. The sensitivity, specificity, and predictive value for the TDB in all of these studies was 100%.
Conclusions: The TDB is a valuable diagnostic technique for confirming tracheal intubation, it correctly detected esophageal and tracheal placement of the tracheal tube in all 400 patients. Results using TDB agree with results using capnography.
Key words: Tracheal intubation. Esophageal intubation. Tracheal Detecting-bulb. Capnogram.
