Spirometric Detection of Esophageal Intubation

Status Withdrawn

Clinical Trial Summary

In endotracheal intubation, it is essential that the trachea is intubated and not the esophagus. In suboptimal situations (outside an operating theatre), malpositioning of the endotracheal tube occurs frequently and is often fatal. The diagnostic tools that are available in the operating theatre are not appropriate for out-of-hospital situations because of several reasons. Moreover, these methods mostly take some time to provide the desired information and don't have optimal specificity and sensitivity. In order to allow fast diagnosis of this potentially fatal complication, we have developed a fully-automatic detection device to diagnose endotracheal tube malpositioning within 2 seconds. A high sensitivity/specificity of the algorithm for waveform-analysis was demonstrated in healthy patients and patients with pulmonary diseases (decreased pulmonary compliance). A new stand-alone device with integrated sensors and microprocessor was developed that gives immediate diagnosis, and stores data for subsequent research purpose. This device will be evaluated in perioperative situations to demonstrate the high sensitivity and specificity in patients in a clinical setting.

Clinical Trial Description

The fundamental algorithm for waveform analysis is unchanged, but an additional detection algorithm is incorporated for improved detection of ventilation efforts. In addition, sensors are integrated, automatic feedback electronics are improved, and the device is made more user friendly to be appropriate for out-of-hospital situations in demanding environments. In addition, waveforms will be recorded for later analysis and evaluation of the diagnostic value of a thoracic push ( a gentle push on the sternum) to detect tube position. ;
