Perioperative Gastrointestinal Myoelectric Activity Measurement Using Wireless External Patches.

ABSTRACT:

Background

Stomach, small intestine, and colon have distinct patterns of contraction related to their function to mix and propel enteric contents. In this study, we aim to measure gut myoelectric activity in the perioperative course using external patches in an animal model.

Methods

Four external patches were placed on the abdominal skin of female Yucatan pigs to record gastrointestinal myoelectric signals for 3 to 5 d. Pigs subsequently underwent anesthesia and placement of internal electrodes on stomach, small intestine, and colon. Signals were collected by a wireless transmitter. Frequencies associated with peristalsis were analyzed for both systems for 6 d postoperatively.

Results

In awake pigs, we found frequency peaks in several ranges, from 4 to 6.5 cycles per
