Endoscopic guidance during percutaneous dilational tracheostomy reduces the risk of paratracheal insertion of the tracheostomy tube but may impair ventilation and does not eliminate the possibility of premature endotracheal extubation. Use of a small-caliber, hollow endotracheal tube exchanger during stomal dilation in lieu of a fiberoptic bronchoscope allows for better ventilation and more secure airway control.
经皮扩张气管切开术中的内镜引导可降低气管切开管气管旁插入的风险，但可能会损害通气功能，且不能消除过早气管插管拔管的可能性。在造口扩张期间使用小口径空心气管内导管交换器代替纤维支气管镜可实现更好的通气和更安全的气道控制。
