Routine use of nasogastric tubes in major surgery is associated with unwarranted risks of aspiration through at least three mechanisms: hypersalivation--allowing pooling of secretions in the hypopharynx, a depressed cough reflex, which is often associated with nasogastric intubation, and various laryngeal and pharyngeal abnormalities that are frequently caused by nasogastric tubes, leading to an inability to handle secretions and protect the airway. Using indirect cinelaryngoscopy, we can accurately document these mechanisms; three representative cases are presented here. Aspiration associated with nasogastric intubation is a newly described but potentially serious complication. Routine use of nasogastric intubation should be abandoned, except when the clinical situation warrants it.
唾液分泌过多——使分泌物在下咽积聚；咳嗽反射受抑制，这常与鼻胃管插管有关；以及鼻胃管频繁导致的各种喉和咽异常，从而导致无法处理分泌物和保护气道。通过间接动态喉镜检查，我们可以准确记录这些机制；这里展示三个典型病例。与鼻胃管插管相关的误吸是一种新描述但可能严重的并发症。除临床情况需要外，应摒弃鼻胃管插管的常规使用。
