What this trial studies
This observational study aims to evaluate the effectiveness of capnography in confirming the correct placement of nasogastric tubes in patients aged 18 and older. Participants will be recruited from various hospital wards, including general medical, geriatric, and intensive care units. The study will compare the results of capnography with established reference standards, such as pH measurement of aspirated gastric contents and X-ray imaging. The goal is to assess the sensitivity and specificity of capnography, as well as its cost-effectiveness and time efficiency in this diagnostic context.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older who require nasogastric tube insertion for medical treatment.
Not a fit: Patients undergoing life-saving interventions at the time of recruitment may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance the accuracy of nasogastric tube placement, leading to improved patient safety and care.
How similar studies have performed: While the use of capnography in other contexts has shown promise, this specific application in nasogastric tube placement is relatively novel and untested.
