OBJECTIVES

The aim of the present study was to compare the effect of metoclopramide and ondansetron treatments on the emergency department observation time in acute gastroenteritis-related nausea and vomiting (NV).

METHODS

The study was conducted retrospectively on 297 patients diagnosed with acute gastroenteritis in a training and research hospital's emergency service observation unit within 6 months. Patients with gastroenteritis who were diagnosed with NV were divided into two groups according to the treatment they received in the observation unit. Patients who received 4 mg ondansetron slow infusion therapy were classified as Group 1, and patients who received 10 mg metoclopramide slow infusion therapy were classified as Group 2.

RESULTS

The average age of the patients was 39.57±18.75 years. Of the 297 participants, 56.6% (168) were female. Among them, 51.5% (153) received ondansetron (Group 1), and 48.5% (144) received metoclopramide (Group 2). 6.9% weakness-numbness and 4.9% akathisia were detected due to metoclopramide use. There were no adverse effects related to ondansetron use. The duration of observation ranged from 19 to 75 min in Group 1 and from 42 to 122 min in Group 2. Nineteen (13.2%) patients in Group 2 and 5 (3.3%) patients in Group 1 revisited the emergency department within 24 h due to ongoing complaints.

CONCLUSION

In conclusion, side effects of weakness and akathisia due to metoclopramide use were observed. However, no side effects were observed due to ondansetron use. Additionally, the use of ondansetron showed a shorter observation time and less recurrent admission to the emergency department. Therefore, ondansetron is a more effective drug in the treatment of NV associated with acute gastroenteritis.
