Effect of preoperative cimetidine and ranitidine on gastric secretion

Autor: James E. Royer, Robert G. Triplett

Publikováno v: Journal of oral and maxillofacial surgery : official journal of the American Association of Oral and Maxillofacial Surgeons. 43(12)

To decrease gastric volume and acidity prior to anesthesia and surgery and decrease the risk of aspiration, a prospective double-blind trial comparing two H2 receptor blockers, cimetidine and ranitidine, was performed. Analysis of gastric contents re
