Measure myoelectric signals with the G-Tech WPS and determine if a correlation exists between signal strength and the rate of gastrointestinal recovery following surgery. Determine the relationship between gastrointestinal myoelectrical signal strength and clinical markers of recovery such as passage of flatus/bowel movement, oral tolerance of diet and discharge readiness.
The purpose of the study is to determine if the myoelectrical measurements made by the G-Tech Wireless Patch System correlate with clinical markers of postoperative recovery such as passage of flatus/bowel movement, oral tolerance of diet and discharge readiness. Subsequently the data will be studied to establish which information in the signals is important in determining when to feed patients and possibly discharge them..
