[Pressures, blood gases, pH, lactate and pyruvate concentrations in the portal venous blood in patients after laparotomy during the first 9 days (author's transl)].
In 24 patients (16 women, 8 men, mean age 60 years), who underwent abdominal operations and who had a uncomplicated postoperative course, a teflon-tube was inserted into the portal vein at the end of laparotomy and remained there for maximal 9 days. The mean values of the portal venous pressure as well as of the portal-central venous pressure gradient are unchanged during the period of all 9 days and are between 7,4 and 7,9 mmHg, between 5,6 and 6,9 mmHg respectively. The arterio-portal venous 0(2)-content difference shows in the mean no fluctuations and is about 2 Vol.%. On the first postoperative day the lactic and pyruvic acid concentrations in the artery and portal vein are moderately, but significantly elevated and decrease to normal values until day 7. - 9.
