Randomized Controlled TrialUmesh's intubation detector (UID) for rapid and reliable identification of tracheal intubation by novices in anaesthetised, paralysed adult patients.
Oesophageal intubation can lead to life threatening complications if left undetected. Several devices and techniques are available to confirm tracheal intubation and for early detection of oesophageal intubation. This study was carried out to evaluate the utility of the Umesh's intubation detector device for rapid and reliable differentiation of tracheal from oesophageal intubation by novice users. ⋯ Out of the total 100 oesophageal intubations, 99 were correctly identified. There were no complications related to the study. Umesh's intubation detector device can be used by novices for rapid and reliable differentiation of tracheal from oesophageal intubation in healthy adult patients.

Randomized Controlled TrialRespiratory parameters as a surrogate marker for duration of intubation: potential application of automated vital sign collection.
Prolonged time during endotracheal tube placement has been associated with poor outcomes, including cardiac arrest and death. For this reason, the accurate measurement of the duration of intubation time is an important metric in studies that evaluate interventions to improve airway outcomes. In the current study we correlated the gaps in routinely measured ventilatory parameters with duration of the intubation procedure to determine if these intervals could be used to accurately calculate the intubation time. ⋯ The gap in measured tidal volume of 39 ± 53 s most closely approximated the actual duration of intubation of 38 ± 28 s, (R(2) = 0.85, y = x - 0.87). During intubation, the disappearance gaps in tidal volume, and the airway pressure and flow waveforms highly correlate with the duration of the intubation procedure and may be useful in the evaluation of airway management interventions. However, just as there are limitations to a labor-intensive method of recording airway management timing, there are limitations to using an automated method.
