Traditional auscultation plays a key role but is limited in objective interpretation and continuous monitoring. Case: We report a case of intraoperative bronchospasm during laparoscopic surgery, detected early through real-time acoustic visualization using a digitalized esophageal stethoscope. The visualization of lung sounds facilitated the rapid identification of expiratory wheezing and abnormal spectrogram patterns characteristic of bronchospasm. Immediate intervention with a bronchodilator resolved the condition without further complications. Conclusions: This case demonstrates the utility of visual stethoscopes in enhancing perioperative respiratory management. Real-time visualization and quantification of lung sounds offer anesthesiologists a valuable tool for early diagnosis and collaborative decision-making during critical respiratory events.<\/jats:p>","DOI":"10.17085\/apm.24194","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T09:25:53Z","timestamp":1753349153000},"page":"277-282","update-policy":"https:\/\/doi.org\/10.17085\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Diagnostic value of visual stethoscopes for detecting bronchospasm in a patient under general anesthesia -
