Early Onset of Regional Intestinal Ischemia Can Be Detected with Carbon Dioxide Tension Measurement Inside the Peritoneal Cavity

Abstract: Unless systemic changes are induced, regional intestinal perfusion deficits cannot be detected with a PCO(2) measurement in the gastric lumen. In pigs, an occlusion of blood flow to an isolated gut segment resulted in a significant increase in intraperitoneal CO(2) tension. Thus, the measurement of intraperitoneal PCO(2) could allow the early detection of regional intestinal ischemia.

“…Several techniques are available to study the microcirculation of the intestine. Deteriorations of the intestinal microcirculation can be assessed indirectly by analyzing tissue oxygenation with Clark electrodes or by monitoring intramucosal pH (pHi) and pCO 2 (PiCO 2 ) using tonometry [17][18][19][20]. In addition, tissue reflectance spectrophotometry may give information on microvascular hemoglobin oxygen saturation (HbO 2 ) and Laser Doppler velocimetry can assess relative changes of microvascular blood perfusion [21,22].…”

“…Unspezifische Veränderungen sind die nichtobligate Laktazidose über 5 mmol/l bei einem "base excess" (BE) <−5 mmol/l, Laktatdehydrogenase (LDH)-und Kreatinkinase-(CK-)Anstieg sowie Hypophosphatämie [4] Ein neuerer, experimenteller Ansatz ist die Messung des pCO 2 in der Peritonealhöhle, der ebenfalls eng mit dem Auftreten regionaler Perfusionsstörungen korreliert [22]. Relativ erfolgreich wird die intramukosale pCO 2 -Messung als "exercise-tonometry" in der präklinischen Diagnostik zur Identifikation von Risikopatienten mit latenten gastrointestinalen Ischämien eingesetzt [23].…”
