Aim: In the present study, the cases admitted to the hospital because of acute gastroenteritis and diagnosed with common rotavirus gastroenteritis were evaluated in terms of demographic, epidemiological, clinical and laboratory data. Methods: The clinical and laboratory data of the cases who applied to Pediatric Emergency Clinic of Selçuk University Faculty of Medicine because of acute gastroenteritis aged 0-18 were evaluated retrospectively in the study. Clinical findings, time of admission, place of observation, blood gas and electrolyte levels, electrolyte imbalance, and length of hospital stays of the patients were recorded. Results: Among the acute gastroenteritis patients who were included in the study, 148 (61.2%) were male and 94 (38.8%) were female. The incidence of hypokalemia in patients who had rotavirus (+) gastroenteritis was statistically significant. Statistically significant differences were detected between the groups in terms of creatinine, potassium and albumin values of biochemical parameters. When the blood gas analyzes of the patients with acute gastroenteritis were evaluated; While acidosis was detected in 24 (9.9%) patients, alkalosis was found in 27 (11.2%) patients. The mean pH value of the patients was found as 7.39±0.05. There was a statistical difference between the rotavirus (-) and rotavirus (+) gastroenteritis groups in terms of pH values (p: 0.015). Conclusion: Cases with metabolic acidosis in rotavirus gastroenteritis are hospitalized more frequently, and for this reason, blood gas studies in cases of rotavirus gastroenteritis will guide clinicians.
