ABSTRACT
Eighteen patients subjected to abdominal surgery were studied. All received general anesthesia and hemodynamic parameters were maintained within 20 percent of basal values. A tononeter was placed in the stomach after induction of anesthesia. Arterial blood gases and samples from the tonometer were obtained 30 minutes after induction and at 2 hours of surgery. Intramucosal pH was calculated using Henderson-Haselbach equations. Basal gastric mucosal pH was 7.4ñ0.1 and did not change during surgery. Two patients had a pH persistently below 7.35 without hemodynamic alterations or systemic acidosis. Gastric mucosal pH is not modified by abdominal surgery and some patients have low values despite the absence of hemodynamic derangement
