Bronchospasm is a rare but potentially life-threatening complication during anesthesia that requires prompt recognition and management. Traditional auscultation plays a key role but is limited in objective interpretation and continuous monitoring.
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.
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.
支气管痉挛是麻醉期间一种罕见但可能危及生命的并发症，需要及时识别和处理。传统听诊起着关键作用，但在客观解读和持续监测方面存在局限性。
我们报告一例腹腔镜手术期间发生的术中支气管痉挛病例，通过使用数字化食管听诊器进行实时声学可视化检查得以早期发现。肺部声音的可视化有助于快速识别呼气哮鸣音以及支气管痉挛特有的异常频谱图模式。立即使用支气管扩张剂进行干预使病情得到缓解，未出现进一步并发症。
本病例证明了可视听诊器在加强围手术期呼吸管理方面的实用性。肺部声音的实时可视化和量化为麻醉医生在关键呼吸事件期间进行早期诊断和协同决策提供了一个有价值的工具。
