[The oxygen tension in the gastric fundus wall in relation to arterial blood supply. Experimental study with intramural pO2-measurement (author's transl)].

Animal experiments in dogs were performed in order to measure oxygen tension in the gastric fundus. For this purpose an intravasal oxygen catheter electrode was inserted into the gastric submucosa. The probe recorded pO2 in an area about 2 cm in length. The oxygen tension was measured in relation to the respective blood supply of stomach. The method is suitable for determining the tendency of oxygen supply of the tissue intraoperatively as well as after implantation postoperatively. The clinical interpretation of the trend of pO2-measurements depends on further experiences.
