Efficacy of a single 24-hour pre-anesthetic dose of proton pump inhibitors
Abstract
BACKGROUND AND AIM: The H(2) receptor antagonist roxatidine is routinely used as an oral pre-anesthetic medication in surgical patients at night and 2 h before surgery. In the present study, we have compared the effects of roxatidine, rabeprazole and lansoprazole given singly at night as an alternative to the standard double roxatidine medication.
METHODS: 120 adult patients undergoing urological surgery were randomly assigned to three groups: roxatidine, rabeprazole and lansoprazole (n = 40 each). Following induction of anesthesia, gastric fluid was obtained by aspiration using a syringe to measure pH and volume of gastric contents.
RESULTS: Gastric volume (14.1 +/- 1.9 mL) in the lansoprazole group was significantly larger than that in roxatidine (8.6 +/- 1.7 mL) and rabeprazole (7.5 +/- 1.1 mL) groups (P 25 mL) in the lansoprazole group was significantly higher than in the roxatidine group (P < 0.05). Gastric pH and volume in all groups were constant even in the afternoon.
CONCLUSION: Single rabeprazole (but not lansoperazole) medication may be a suitable alternative to standard roxatidine for prophylaxis of acid aspiration pneumonia.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 120 participants or records.
