Comparison of RightSpot pH Indicator & RightLevel pH Detector With X-Ray Verification for FT or G-Tube Placement

This study has been terminated.

Replacing a G tube and placing feeding tubes is standard in the Emergency Department (ED) and ICU, respectively. However placement requires a chest or abdominal x-ray to confirm correct position. The investigators are testing the accuracy of the FDA approved devices RightSpot pH Indicator & RightLevel pH Detector in determining correct position based upon pH which will then be correlated with the standard of care x-ray.

Further study details as provided by Timothy Havens, MD, St. Louis University:

Primary Outcome Measures:
  • pH measurement of gastric or duodenal secretions [ Time Frame: Within 24 hours of tube insertion prior to the initiation of tube feeding ]
    The pH measurement obtained will be used to determine correct placement of the gastric or feeding tube as compared to the gold standard method of X-ray following gastrograffin administration

Secondary Outcome Measures:
  • Costs associated with G-tube reinsertion in the Emergency Department [ Time Frame: Within 2 weeks of Discharge from the Emergency Department ]
    A collection of all costs related to the Emergency Department visit related to the replacement of the G-tube

Enrollment: 11
Actual Study Start Date: March 14, 2013
Study Completion Date: May 25, 2016
Primary Completion Date: May 25, 2016 (Final data collection date for primary outcome measure)
