ABSTRACT
Purpose : The purpose of this study was to determine the clinical value of bicarbonate gap (BG) in acute gastroenteritis by comparison of clinical manifestations and laboratory findings.
Methods : We retrospectively analyzed 135 patients who had acute gastroenteritis. We classified them into two groups: $BG{leq}-5$ (group A), BG>-5 (group B). We made a comparative study for clinical manifestations, serum electrolyte, albumin, protein, blood urea nitrogen (BUN), creatinine, anion gap (AG), delta anion gap (${Delta}AG$) and delta bicarbonate (${Delta}HCO_3{^-}$) between the two groups.
Results : The duration of hospitalization and diarrhea was significantly longer in group A than group B. In laboratory findings, serum sodium, serum total $CO_2$, total protein, $AG_{corrected}$ and ${Delta}AG$ were lower in group A than group B. ${Delta}HCO_3{^-}$ and chloride were higher in group A than group B.
Conclusion : BG may be a sensitive predictor enough to access the severity of acute gastroenteritis.
Key words: Acute gastroenteritis | Metabolic acidosis | Delta anion gap | Delta bicarbonate
