Background: Pregnant women are at high risk of experiencing gastric fluid aspiration, which is known as Mendelson's syndrome. The possibility of aspiration increases in an emergency condition. Low pH and high volume of aspirate increase the severity of aspiration. Ranitidine and antacids can increase gastric pH. This study aimed to compare gastric pH after receiving ranitidine, antacids, and ranitidine-antacids combination as premedication in patients undergoing an emergency cesarean section (C-section). Patients and Methods: This study is a true-experimental design on 27 participants who underwent a C-section at Dr. Saiful Anwar Hospital. The R group received ranitidine 50 mg, the A group received 10 ml of antacids, and the C group received the combination of both. The measurement of gastric pH was carried out on 0, 5, 15, 30, 45, and 60 min after premedication. The data were analyzed using the one-way ANOVA test. Results: The average change in gastric pH is better seen in the antacids group. The gastric pH increases from 3.19 ± 1.04 to 4.64 ± 1.20 at 60 min after premedication (P > 0.05). Ranitidine administration showed better results at 5, 15, and 30 min after premedication (P > 0.05). The combination of ranitidine and antacids showed better results at 45 and 60 min after premedication (P > 0.05). Conclusion: There is no significant difference in gastric pH after receiving premedication in patients undergoing a C-section. However, all groups show an increase in gastric pH after receiving premedication. The administration of ranitidine and antacids combination is not better than a single dose of ranitidine or antacids.
