The aims of this study were to determine the time to detect ETCO2 following intubation during resuscitation of infants born prematurely and whether it differed according to maturity at birth or the Apgar scores (as a measure of the infant’s condition after birth).Design Analysis of recordings of respiratory function monitoring.Setting Two tertiary perinatal centres.Patients Sixty-four infants, with median gestational age of 27 (range 23–34)weeks.Interventions Respiratory function monitoring during resuscitation in the delivery suite.Main outcome measures The time following intubation for ETCO2 levels to be initially detected and to reach 4 mm Hg and 15 mm Hg.Results The median time for initial detection of ETCO2 following intubation was 3.7 (range 0–44) s, which was significantly shorter than the median time for ETCO2 to reach 4 mm Hg (5.3 (range 0–727) s) and to reach 15 mm Hg (8.1 (range 0–827) s) (both P<0.001). There were significant correlations between the time for ETCO2 to reach 4 mm Hg (r=−0.44, P>0.001) and 15 mm Hg (r=−0.48, P<0.001) and gestational age but not with the Apgar scores.Conclusions The time for ETCO2 to be detected following intubation in the delivery suite is variable emphasising the importance of using clinical indicators to assess correct endotracheal tube position in addition to ETCO2 monitoring. Capnography is likely to detect ETCO2 faster than colorimetric devices.
