Contraindications to blind nasogastric tube insertion
Fluoroscopically guided intubation should be considered in the following cases:
Base of skull fracture
Nasal injuries
Deviation of the nasal septum
Hiatus hernia and gastro-oesophageal reflux - if severe the risk of aspiration may be high
Functional problems such as loss of swallow or gag reflex
Oesophageal or gastric abnormalities e.g. stricture, pharangeal pouch, pharangeal
compression, perforation, fistula - may require fluoroscopically guided intubation
Known oesophageal varices, ulceration or haemangioma (due to possibility of causing trauma)
Postoperative patients who have had upper GI surgery, with or without an anastamotic leak
Trauma from poisoning (e.g. Oral consumption of bleach
Many contraindications are relative and a decision to place an NG tube in
these patients and the mode of intubation may still be taken by more senior
members of the team
In some of these situations use of fluoroscopic guidance can make
intubation safer
