Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A live-video system (NCKU-NG system) was developed to assist in the placement of an enteral feeding tube. This system consists of a camera and light source that can be inserted into the commercial NG tube to view live video during feeding tube placement. Manual air insufflation can be used to aid feeding tube placement and improve visualization of anatomic landmarks. After the procedure, an abdominal X-ray is done to confirm the position of the feeding tube.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study used 15 Fr feeding tubes with an outer diameter of 4.5 mm and an inner diameter of 3.5 mm (Freka®, Bad Homburg, Germany). Patients were advised to maintain nothing by mouth (NPO) for at least four hours before the placement. An insufflation device (Olympus, Tokyo, Japan) was utilized whenever necessary to facilitate feeding tube placement or confirm its position. In cases where misplacement into the trachea was detected, the feeding tube was carefully withdrawn and reinserted into stomach. After successful insertion, all feeding tubes were securely fixed with tape on the nose. The position of NG tube was reconfirmed by traditional auscultation. Chest X-ray imaging was performed for every patient after the NG tube placement to verify the positioning of the tube by the primary care physician. Time to visual confirmation of stomach position, for completing tube placement with/without air insufflation were recorded. Numbers of attempts, vocal cord/trachea visualization and air insufflation were also recorded. A study assistant monitored the patient's condition for the subsequent seven days, recording any observed complications or adverse events.
