Oxygen-tension measurements - the first step towards prevention and early detection of anastomotic leakage

Many patients still die every year as a result of anastomotic leakage after surgery. The medical world needs an objective aid to detect leakage during surgery and during the critical recovery period.

description Many patients still die every year as a result of anastomotic leakage after surgery. The medical world needs an objective aid to detect leakage during surgery and during the critical recovery period. We propose a miniature measurement system to detect adequate tissue oxygenation pre-and postoperatively (continuously for 7 days) on the colon. The sensor chip should include an oxygen-saturation sensor, an oxygen-tension sensor, a carbon dioxide tension sensor and a temperature sensor. The work presented here focuses on the measurements done with the oxygen-tension and temperature sensors. In-vitro measurements were carried out to test the sensor system and initial in-vivo tests were performed on a rat kidney, during an ischemia-reperfusion experiment.
