In modern thoracic surgery, double-lumen endobronchial tube (DLET) is the first choice for intubation. One lung ventilation can be perfectly performed by DLET, with the benefit of maintaining adequate gas exchange and establishing great surgical field. Traditionally, we use stethoscope and fiberscope for DLET site evaluation. However, there are some concerns over traditional methods. Stethoscope evaluation can be subjective from person to person; fiberscope, on the other hand, can cause additional bronchial injury as it is an invasive procedure. We hope to utilize patches, also known as electronic stethoscope, which provide non-invasive and visualized spectrum information, to assist anesthesiologists evaluate DLET insertion site more precisely in patients undergo thoracic surgery.

Primary | Accuracy of DLET intubation | By using electronic stethoscope to record breath sound, we can analyze visualized waveform and spectrum to predict probable site and depth of DLET. Then we use fiberscope for actual result. By comparing records of electronic stethoscope and fiberscope, we hope to find correlation between these two methods of evaluating appropriate intubation of DLET. | Intraoperative (Start record the first breath sound after intubation when supine. After changing patient's position to lateral decubitus, the second breath sound is recorded. The electronic stethoscope is retrieved before the operation starts.) | |
Secondary | Correlation of breath sound and airway pressure | During collection of breath sound, we also record airway pressure showed on ventilator at the same time. Theoretically, elevated airway pressure can be seen if airway obstruction or inappropriate intubation is happening. We hope to find correlation between airway pressure and breath sound collected by electronic stethoscope, for possible earlier detection, diagnosis and treatment. | Intraoperative (Start record the first breath sound after intubation when supine. After changing patient's position to lateral decubitus, the second breath sound is recorded. The electronic stethoscope is retrieved before the operation starts.) |
