title: Effect of sucralfate on gastric intramucosal pH in critically ill patients.
abstract: OBJECTIVE
  To determine whether sucralfate administration affects the tonometric measurement of gastric intramucosal pH (pHi).
  
  
  METHODS
  Non-randomized observational study.
  
  
  METHODS
  General intensive care unit of a teaching hospital.
  
  
  METHODS
  Twenty critically ill, mechanically ventilated, consecutively admitted patients requiring an arterial catheter and nasogastric tube.
  
  
  METHODS
  Tonometer placement and sucralfate administration.
  
  
  RESULTS
  We simultaneously determined tonometer saline PCO2 (PCO2i), arterial blood gases, pH of gastric juice and pHi. These parameters were evaluated immediately before sucralfate administration, and 2 h and 4 h after. We did not detect any change in either PCO2i or pHi after sucralfate administration (PCO2i: basal 6.4 +/- 1.7, 2 h 6.3 +/- 1.7, 4 h 6.3 +/- 1.7; pHi: basal 7.35 +/- 0.13, 2 h 7.36 +/- 0.12, 4 h 7.36 +/- 0.12).
  
  
  CONCLUSIONS
  Sucralfate does not affect the tonometric measurement of PCO2i and pHi.
