ObjectiveTo determine the practical value of the new pediatric disposable ETCO2 detector Pedi-CAP in verifying endotracheal tube placement in neonatal resuscitation.MethodsInfants who required endotracheal intubation in the delivery room or the neonatal intensive care unit (NICU) were included in a prospective study in which the endotracheal tube placement was determined clinically and simultaneously by the Pedi-CAP and confirmed by chest radiograph. The Pedi-CAP and clinical evaluation determination times of the endotracheal tube placement were measured and compared. The accuracy and ease of the Pedi-CAP use were tested.ResultsForty-five newborns (450 to 4620 gm) who needed endotracheal intubation were included in the study. Twenty-four (53.3%) were intubated in the delivery room and 21 (46.7%) in the NICU. The Pedi-CAP color indicator correlated with the clinical evaluation and radiograph findings of proper intubation in 30 of 33 patients (sensitivity 91%, specificity 100%, positive predictive value 100%, and negative predictive value 80%). There were three false-negative results in patients with severe cardiorespiratory depression. The Pedi-CAP color indicator correlated with the clinical evaluation for the ET-tube being in the esophagus in 12 of 12 patients (sensitivity, specificity, and positive and negative predictive value were all 100%). The time required to determine the tube position by clinical evaluation was 0 to 90 seconds (mean = 39.7 seconds; SD +/- 15.3 seconds). The time required with the disposable ETCO2 detector was 4 to 12 seconds (mean = 8.1 seconds; SD +/- 2.9 seconds; p < 0.001).ConclusionThe use of a disposable pediatric endotracheal CO2 detector significantly reduces the time spent in verifying the endotracheal tube position (trachea versus esophagus) in newborns, including premature babies with body weight < 1000 gm. This is of particular benefit to babies who are erroneously intubated in the esophagus, because using the device allows much faster detection of this problem and much earlier reintubation.
