Abstract :

Background: Dehydration is associated with poor outcome after acute ischemic stroke. However, the relationship between hydration therapy during acute ischemic stroke and clinical outcome remains unclear. Our study aimed to determine whether providing hydration therapy to patients with a blood urea nitrogen/creatinine (BUN/Cr) ratio ΓΆΒ?Β¥15 improves their clinical outcome. Methods: A non-blinded, phase II single arm prospective study of patients with acute ischemic stroke and BUN/Cr ratio ΓΆΒ?Β¥15 was conducted from January 2011 to December 2013, with historical controls from November 2007 to June 2010. The hydration group received intravenous bolus (300ΓΆΒ?Β?500 mL) saline followed by maintenance saline infusion (40ΓΆΒ?Β?80 mL/h for the first 72 h), while the control group received maintenance saline infusion (40ΓΆΒ?Β?60 mL/h for the first 24 h and 0ΓΆΒ?Β?60 mL/h for 24ΓΆΒ?Β?72 h). The study endpoint was the proportion of patients with favorable outcome, defined as modified Rankin scale (mRS) ΓΆΒ?Β¤ 2 at 3 months post stroke. Results: Overall, 237 patients were enrolled (hydration group, n = 134; control group, n = 103). The median volume of infused saline from day 1 to day 3 was significantly larger (P < 0.001) and the rate of favorable outcome at 3 months post stroke was significantly higher (P =0.016) in the hydration group. Dividing acute ischemic stroke into lacunar and non-lacunar subtypes, the difference was significant only in the lacunar stroke subtype (P=0.020). Conclusion: Thus, providing saline hydration therapy to patients with acute ischemic stroke based on BUN/Cr ratio can significantly increase the rate of favorable clinical outcome with functional independence at 3 months post stroke.
