Vagale stimulator om het gebruik van een neussonde te verminderen
De rol van een vagale stimulator om de frequentie en duur van de neussonde na een buikoperatie te verminderen
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.

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 tune can lead to a local trauma, bleeding and pain. Pain represents a major complaint among those with POI, often contributing to prolonged hospital stays.
It has been well established that bile function is modulated by the vagal nerve. Therefore, a non-invasive vagal stimulation administered post-operatively may facilitate the resolution of POI, accelerate the return to bile function and shorter the hospital length of stay following major abdominal surgery. Anecdotally, the use of a vagal nerve stimulator has been shown to avoid the placement of a NG tube.
In most cases, postoperative ileus is considered a benign and reversible complication that occurs in 10-30% of patients following abdominal surgery. The use of anesthesia, the use of opioids and anti-inflammatory drugs, hypokalemia, local inflammation, local hematoma, can all contribute to the development of a POI, and its treatment often requires the placement of a NG tube. The placement of a NG tube is not always effective if it is not positioned properly and is associated of a local trauma, misplacement of the NG tube, prolonged pain, and hospital stay. It is always very uncomfortable for the patient. Since the gastro-intestinal motility is regulated by the vagal nerve, the use of non-invasive vagal nerve stimulator may represent an interesting technique to reduce the frequency of this complications associated with the use of a nasogastric tube including local trauma, misplacement and pain on insertion, and constant pain as long as the NG tube remain in place.

Experimenteel: Vagal Nerve Stimulator Group
This arm of the study will be randomly assigned to receive the active vagal nerve stimulator device which is placed via electrodes on each side of the neck. The active device will experience two 45-minute sessions daily of vagal nerve stimulation until their Nasogastric (NG) tube is removed. |
The vagal nerve stimulator device is a nonsignificant risk device that provides electrical impulses to the vagus nerve, located in the neck and ear regions. The device (pulse generator) and a wire lead (insulated wire) with electrodes on the end of the wire will send the electrical signals along the vagus nerve to your brainstem to activate various neurochemical coordinates. |

Sham-vergelijker: Placebo Vagal Nerve Stimulator Group
This arm of the study will be randomly assigned to receive a sham device that mirrors that of the active vagal nerve stimulator devices. The sham device arm will experience two 45-minute sessions daily of placebo vagal nerve stimulation until their Nasogastric (NG) tube is removed. |
The sham vagal nerve stimulator device is a nonsignificant risk device that mirrors that of the active stimulator but does not provide electrical impulses to the vagus nerve. |
