Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
In this study, the investigators aim to conduct a pilot test of the AbStats device. The v2.0 prototype is a low-profile set of sensors that fits externally around the abdomen and is embedded with specialized wireless sensors. The device continuously, safely, and comfortably monitors intraabdominal acoustic signals, and stores the data in a HIPAA compliant software system. The investigators will focus this trial on a high-impact inpatient population: ileus in the surgical critical care unit. The investigators will compare the device's signal profiles in patients with ileus vs those who tolerate feeding without high gastric feed residual. Our study will have the following specific aims: Specific Aim #1: To measure the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of initiation day ("PID 0") AGIS signals in predicting PID #1 feeding failure. Specific Aim #2: Among patients tolerating feeds on PID #1, to measure the sensitivity, specificity, PPV, and NPV of AGIS in predicting feeding failure on subsequent icu days.
