PrevisEA^™ is a noninvasive, easy-to-use device that analyzes intestinal sounds for a validated acoustic biomarker of digestive health which is displayed as the Previs^™ Index.¹ The device is placed on the patient’s abdomen within one hour of surgery completion. At postoperative hour 12, the Previs Index displays “High Risk” or “Low Risk”. “High Risk” indicates that digestive health is likely insufficient to support early oral refeeding and the patient is likely to develop gastrointestinal impairment (GII) mostly commonly associated with postoperative ileus or less frequently due other causes.² “Low Risk” indicates that digestive health can likely support early oral refeeding without subsequent GII. In PrevisEA clinical trials, GII was defined as vomiting, need for nasogastric tube insertion or a physician-ordered reversal of diet greater than 24 hours after completion of surgery.
