TY - JOUR T1 - The Effect of Maintenance Fluid tonicity on Serum Sodium in Pediatric Patients A1 - Khadijeh Ghassemi A1 - Sahar Montazeri A1 - Mehdi Mahmoudpour A1 - Marzieh Mahmoudi A1 - Vahid Mohammadi JF - International Journal of Pharmaceutical And Phytopharmacological Research JO - Int J Pharm Phytopharmacol Res SN - 2250-1029 Y1 - 2019 VL - 9 IS - 1 SP - 66 EP - 70 N2 - Background: Hyponatremia is the most common electrolyte imbalance in clinical medicine. About 15% of hospitalized patients have hyponatremia. The type of administered intravenous fluid may lead to changes in serum sodium concentrations. Objectives: The aim of this study was to compare the effect of 1/3 2/3 fluid versus dextrose 5% half saline as intravenous maintenance fluid on serum sodium levels. Methods: In this cross sectional study, children aged 2 months to 12 years old admitted to the general pediatric ward of Bushehr Persian Gulf Shohada hospital were evaluated. They were randomly assigned to take 1/3 2/3 fluid (with 51 mEq/Lit sodium) or dextrose 5% half saline (with 77 mEq/Lit sodium). Serum sodium levels were checked before and 24 hours after the initiation of the IV fluid therapy. Results: A total of 295 patients were enrolled in this study and randomly received 1/3 2/3 fluid (N=152) or dextrose half saline (N=143). In children aged less than 5 years, there was a significant change in serum sodium levels after administration of 1/3 2/3 fluid (P=0.011 in UR - https://eijppr.com/article/the-effect-of-maintenance-fluid-tonicity-on-serum-sodium-in-pediatric-patients ER -
