Abstract

Nasogastric tube (NGT) insertion is a common bedside procedure, yet conventional blind placement confirms tube position only after insertion, when misplacement may already have caused harm. Assisted techniques that guide the tube during insertion have emerged, but evidence comparing them with blind placement remains fragmented. This review compares blind insertion with optical, electromagnetic, imaging-guided and endoscopy-guided insertion in terms of placement success, insertion and confirmation time, respiratory misplacement, local trauma, post-pyloric access and practical feasibility. Clinical studies, systematic reviews and guidelines were reviewed narratively. Blind insertion relies on the inaccurate nose-earlobe-xiphoid estimate. In anaesthetized patients, it achieves first-attempt success of only 56.7–82.7%, and it carries airway misplacement in 1.9–2.9% and in-procedure pneumothorax in 0.52% of placements. Assisted techniques detected airway entry in real time, with zero or near-zero unrecognized respiratory misplacement. Optical, ultrasound, fluoroscopic, and endoscopic guidance achieved 94–99% placement success. Electromagnetic guidance matched blind gastric placement (63.1% vs 65.5%) but had no airway misplacement. Assisted methods shortened confirmation time, reduced repeated attempts, and clearly outperformed blind insertion for post-pyloric placement. Their limitations include cost, training needs, operator dependence, and, for fluoroscopy and endoscopy, radiation, sedation, and patient transport. Most evidence comes from small, single-center studies. Blind insertion remains reasonable for low-risk, cooperative patients. Assisted techniques should be prioritized for patients with impaired airway reflexes, contraindications to blind passage, previous failed attempts, or a need for post-pyloric feeding, with the modality chosen according to the clinical situation and local resources.
