title: [Ventricular tonometry during laparoscopic cholecystectomy].
abstract: Changes in gastric mucosal-pH (pHi) are correlated with the oxygenation of the gastric mucosa. We have measured the gastric mucosal-pH (pHi) in 11 healthy patients undergoing laparoscopic cholecystectomy and calculated the "pH-gap" as the difference between arterial-pH and pHi. The measurements were obtained at 30 minute intervals from the induction of anaesthesia to the end of surgery. The pHi decreased during surgery, but the pH-gap showed only insignificant changes. The results of this study did therefore not indicate gastric mucosal hypoxia during laparoscopic cholecystectomy.
