Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (1)

  • Correlation of breath sound and airway pressure

    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.)

Study Arms (1)

Patients underwent thoracic surgery

Patients underwent thoracic surgery and general anesthesia with usage of DLET are included. Those patients with abnormal breath sound, pulmonary disease or history of cardiothoracic surgery are excluded.

Device: electronic stethoscope

Interventions

It includes main machine and auscultation patch, which can stick on patient's body to collect and amplify breath sound.
