Vagal Stimulator to Reduce Nasogastric Tube Use

Study overview

Abdominal surgery, laparoscopic or open, is frequently performed at UPMC Shadyside hospital. One of the most frequent complications following abdominal surgery is a postoperative ileus. Although postoperative ileus may be the result of obstruction or leakage, in most cases postoperative ileus (POI) is the result of local irritation because of fluid overload, exogenous opioids, neurohormonal dysfunction, gastrointestinal stretch, local bleeding and inflammation. POI usually lasts between 2 to 7 days. In most cases, a nasogastric tube (NG tube) is used to relieve that gastric pressure until the resolution of the POI. The placement of a NG tube can lead to a local trauma, bleeding and pain. Pain represents a major complaint among those with POI, often contributing to prolonged hospital stays.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
