Device to predict gastrointestinal impairment after surgery

A Minimal-Risk, Multi-Center, Prospective, Clinical Trial to Evaluate the PrevisEA Device for Predicting Gastrointestinal Impairment

Not applicable Interventional Entac Medical Inc. · NCT04880473

This study is testing a new device that listens to sounds from the stomach and intestines to see if it can help predict problems after major abdominal surgery.

What this trial studies

The PrevisEA device is a noninvasive, disposable tool that analyzes sounds from the gastrointestinal tract to predict gastrointestinal impairment, particularly after major abdominal surgeries. This impairment can lead to complications such as postoperative ileus or bowel obstruction, which affect a patient's ability to resume oral feeding. The device operates without informing medical decisions during the study, and researchers will remain blinded to its results. The study aims to evaluate the effectiveness of this device in a controlled surgical setting.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 90 undergoing elective intestinal resection surgeries.

Not a fit: Patients with allergies to device components or those undergoing specific types of surgeries not included in the study may not benefit.

Why it matters

Potential benefit: If successful, this device could help predict gastrointestinal complications early, potentially improving patient outcomes and recovery times after surgery.

How similar studies have performed: While the approach of using audio spectral analysis is innovative, similar studies have not been widely reported, making this a novel investigation.
