asogastric tube Placement under Sonographic Observation: a comparison study of ultrasound and chest radiograph in mechanically ventilated patients

Not Applicable

Completed

• Conditions: Critical Care patients; mechanically ventilated patients; patients requiring enteral feeding; Other - Research that is not of generic health relevance and not applicable to specific health categories listed above

• Registration Number: ACTRN12620000539932
• Lead Sponsor: Carena McMullen

Brief Summary

This study aimed to examine the accuracy of ultrasound for verifying the position of the nasogastric tube in mechanically ventilated intensive care patients. Historically the gold standard of care is chest radiograph, this incurs radiation and necessitates moving the patient which incurs a potential for increased risk of accidental endotracheal, venous and arterial line dislodgement. Patient enrolled will be mechanically ventilated and need a nasogastric tube for the treatment or diagnosis of their admitting illness. The nasogastric could be identified in the neck with ultrasound with 88% sensitivity and in the stomach with 64% sensitivity. Limitations to this study include the sample size of 25 and the absence of true negative for example ultrasound findings of a misplaced nasogastric tube so specificity can not be calculated.

Primary Outcome Measures

Name	Time	Method
Percentage of ultrasound scans correctly identifying the NGT in the oesophagus and epigastrium when compared with chest x-ray[Prior to use of the nasogastric tube]

Secondary Outcome Measures

Name	Time	Method
The effectiveness of a non radiologist ultrasound scan of a nasogastric tube will be assessed with the use of chest radiograph.<br>The chest radiograph will assess the position of the nasogastric tube position for comparison against ultrasound findings. [prior to chest x-ray confirmation ]
