| ABSTRACT |
Study objective: To determine the ability of a disposable end-tidal CO2 detector to accurately confirm or refute endotracheal tube placement.
Disign : Seventy prospective emergency intubations.
Setting: Emergency intubations performed in the emergency department.
Type of participants : Intubations were performed by emergency medicine residents and in terns.
Interventions : The FEF™ CO2 detector was applied after 70 emergency intubations. Notation of color change indicating intratracheal placement was recorded in each case. Confirmation or refutation of the detector's results was determined subsequently through traditional methods. Results : The sensitivity for confimation of endotracheal intubation in 50 nonarrested patients was 100%. However, only 14 of 20 patients(sensitivity, 78% ) in cardiac arrest had endotracheal intubation in 20 arrested patients in whom color change was noted(100% ). Overall sensitivity for tracheal intubation was 94%, and specificity for tracheal intubation was 100%.
Conclusion
The FEF™ CO2 detector reliably detects intratracheal placement in the nonarrested patient. Its use in prolonged cardiac arrest merits further study.
