Analysis of Breath Sound During Thoracic Surgery
21. februar 2022 opdateret af: Taipei Veterans General Hospital, Taiwan
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.

Detaljeret beskrivelse
This is an observational study.
We use electronic stethoscope, which stick on patient's anterior chest, to record breath sound after intubation.
The soundtrack will then be transformed to visualized waveform, enabling us to analyze and compare with actual result confirmed by fiberscope.

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

Accuracy of DLET intubation
Tidsramme: 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.)
|
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.

Correlation of breath sound and airway pressure
Tidsramme: 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.)
|
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.
