Surgical teachers have a fondness for joking around. Xie Wanying listened and understood that Teacher Nie would never casually call doctors from other departments to join; there must be a solid rationale behind it. After all, colleagues from other departments have their own busy workloads.
For instance, everyone knows that doctors from cardiothoracic surgery and respiratory medicine are often summoned because they use bronchoscopes. But why call in doctors from the cardiology department? Senior Jin is a renowned expert in cardiovascular intervention. Teacher Nie must have called Senior Jin with the intention of leveraging cardiovascular intervention to solve the child's issue.
This brings up an obscure piece of knowledge: bronchial foreign body retrieval, aside from the commonly known fiber optic bronchoscopy or, when unavoidable, cardiothoracic surgery, can also be performed using intervention techniques from cardiology—a method less commonly seen or heard about.
