title: A study of 13 patients with gastric tube in place after esophageal resection: use of omeprazole to decrease gastric acidity and volume.
abstract: OBJECTIVE
  To investigate whether oral omeprazole 20 mg decreases the risk of aspiration pneumonia in patients with gastric tube reconstruction.
  
  
  METHODS
  Consecutive study.
  
  
  METHODS
  Operation room of cancer center.
  
  
  METHODS
  Thirteen patients with gastric tube reconstruction for esophageal cancer.
  
  
  METHODS
  Oral omeprazole 20 mg was given the night before surgery. A rapid-sequence induction with cricoid pressure was employed for induction of anesthesia. After tracheal intubation, a nasogastric catheter was inserted into the gastric tube and the contents were aspirated.
  
  
  RESULTS
  The pH and volume of the gastric contents were measured. The pH and volume of the gastric tube contents were 4.5 +/- 1.6 (range from 2.5 to 7.0) and 9.5 +/- 10.2 mL (range from 0 to 30 mL), respectively. Food residue was recognized in nine patients. There was no patient with a pH below 2.5 and a volume of 25 mL or greater.
  
  
  CONCLUSIONS
  Omeprazole 20 mg decreased the acidity and volume of the gastric tube contents and reduced the risk of aspiration pneumonia in patients with a gastric tube in place.
