What this trial studies

This observational study focuses on the analytical validation of the Stream™ Platform, which includes the Origin™ inline biosensor system designed for real-time monitoring of pH levels in abdominal drainage fluid after gastrointestinal surgery. The study will assess the precision, linearity, and analytical specificity of pH measurements taken by the Origin™ device using both calibration fluids and actual patient samples. It aims to establish the reliability of this technology in detecting postoperative complications through accurate monitoring of drainage fluid characteristics. The study will involve multiple centers and will collect daily samples from eligible patients undergoing specific types of surgeries.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who have undergone open or laparoscopic gastrointestinal surgery with abdominal drainage.

Not a fit: Patients expected to be discharged less than 8 hours post-surgery or those with known infectious diseases affecting the gastrointestinal tract may not benefit from this study.

Why it matters

Potential benefit: If successful, this platform could significantly enhance postoperative monitoring, leading to earlier detection of complications and improved patient outcomes.

How similar studies have performed: While this approach is innovative, similar studies focusing on real-time monitoring of physiological parameters have shown promise in improving patient care.
