Bronchial spasm after inducing anesthesia followed by intraoperative tracheal catheter obstruction: a case report

Background: Bronchial spasm and tracheal tube obstruction are rare but dangerous emergencies during anesthesia. It is even rarer for these two situations to occur simultaneously in the same patient. Case presentation In September 2022, a patient with endotracheal intubation experienced bronchospasm and then sputum obstruction of the tracheal tube during general anesthesia in our hospital. Thanks to the rapid identification of the etiology and timely intervention, the patient successfully completed the operation without any adverse outcomes. Conclusion: During general anesthesia, various unexpected situations may occur at any time, and we need to constantly pay attention to the patient's vital signs. In case of emergency situations, timely detection and prompt handling can save the patient's life
