The SCOTI (Sonomatic Confirmation of Tracheal Intubation) is a newly marketed electronic device that relies on recognition of a resonating frequency for detection of tracheal intubation. It was compared with the modified Wee oesophageal intubation detection device, which works on a mechanical principle, in 50 elective surgical patients. All had simultaneous tracheal and oesophageal intubations. The Wee device correctly detected oesophageal and tracheal placement of the tracheal tube in all 50 patients. The SCOTI device incorrectly identified 1 of 50 tracheal intubations and was unable to identify the position of another. It correctly identified all 50 oesophageal intubations. The SCOTI is no better than the simple, cheap and reliable Wee device.
SCOTI（气管插管的超声确认）是一种新上市的电子设备，它依靠识别共振频率来检测气管插管。在50例择期手术患者中，将其与基于机械原理工作的改良Wee食管插管检测设备进行了比较。所有患者均同时进行气管插管和食管插管。Wee设备在所有50例患者中均正确检测到气管导管的食管和气管位置。SCOTI设备在50例气管插管中错误识别了1例，并且无法识别另一例的位置。它正确识别了所有50例食管插管。SCOTI并不比简单、便宜且可靠的Wee设备更好。
