Pulmonary damage resulting from aspiration of gastric contents has been reported to be related to the acidity of the aspirate. The purpose of this research was to evaluate if Alka-Seltzer Effervescent and/or Bicitra, ingested preoperatively, increased gastric pH >2.5 and if so, which of the two products sustained the increase for the greatest length of time. Twenty-nine subjects ingested either Alka-Seltzer Effervescent (n = 15) or Bicitra (n = 14) during the immediate preoperative period. Gastric pH was analyzed at 30 and 60 minutes post-ingestion via oro- or naso-gastric tube. Repeated measures Analysis of Variance demonstrated that both antacids elevated gastric pH >2.5 at 30 and 60 minutes post-ingestion. However, Alka-Seltzer Effervescent produced a statistically significant greater (p =.032) increase in gastric pH than Bicitra at both 30 and 60 minutes post-ingestion.Type
