Analysis of Breath Sounds During Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Electronic stethoscope monitoring: Application of electronic stethoscope patches on the patient's chest during surgery to record breath sounds for subsequent analysis. No therapeutic intervention is given; this is a monitoring/observational tool.

Study summary

This study aims to analyze breath sounds during surgery by using electronic stethoscope sensors attached to patients under general anesthesia. The study will evaluate whether breath sound monitoring can provide useful information for respiratory management, assist anesthesiologists in early detection of abnormal breathing events, and support safer perioperative care. A total of 30 adult patients undergoing elective surgery under general anesthesia will be enrolled.

Eligibility

Primary outcome measure(s)

• Accuracy of electronic breath sound monitoring during surgery — During surgery (from induction of anesthesia until emergence)
  Assessment will be based on the proportion of intraoperative respiratory events correctly identified by the electronic breath sound monitoring system compared with standard clinical assessment.
