Abstract

This study compares the performance of two commercially available devices (Ambu. TubeChek™ and SCOTI™ in establishing endotracheal (ET) tube position (oesophageal vs. tracheal) in a mannequin and in miniature pigs. The Ambu TubeChek is a syringe-type, Oesophageal Detector Device (ODD) that fits to the endotracheal tube connector. Air is aspirated easily from the rigid trachea, but not from the collapsing esophagus. The Sonomatic Confirmation of Tracheal Intubation device (SCOTI) is a lightweight battery-powered, sonomatic device. It emits sound waves into the tube and analyzes the reflection. The SCOTI purports to enable a user-independent and carbon-dioxide-independent assessment of tube position following intubation.

Intubation followed by tube position assessment with Ambu TubeChek (ODD) was significantly faster and easier with the ODD than with the SCOTI. The SCOTI cannot differentiate tracheal from oesophageal ET-tube position in mini-pigs.

In situations in which capnometry is not available or the CO2 production and transport are compromised (CPR), we recommend the use of an Oesophageal Detector Device (ODD) rather than the SOCTI.
