The Sonomatic Confirmation of Tracheal Intubation (SCOTI, Penlon, UK) device was evaluated in the laboratory with cut and uncut tracheal tubes and in 50 adult patients who underwent tracheal and oesophageal intubation with uncut tracheal tubes. We could not configure the SCOTI reliably with cut tracheal tubes. In the clinical study using uncut tubes the SCOTI identified all oesophageal intubations, but was only able to identify 84% (95% CI: 73.8-94.2%) of tracheal intubations. We recommend caution in using this device and further independent evaluation to determine its reliability.
对声控气管插管确认装置（SCOTI，Penlon公司，英国）在实验室中使用切割和未切割的气管导管进行了评估，并在50例使用未切割气管导管进行气管和食管插管的成年患者中进行了评估。我们无法使用切割的气管导管可靠地配置SCOTI。在使用未切割导管的临床研究中，SCOTI识别出了所有食管插管，但仅能识别84%（95%置信区间：73.8 - 94.2%）的气管插管。我们建议谨慎使用该装置，并进行进一步的独立评估以确定其可靠性。
