However, the relatively high concentration of chloride in normal saline (NS) might lead to hyperchloremia or acute kidney injury, comparing with multi-electrolyte solutions (BMES). The aim of the study is to compare the incidence of hyperchloremia in aSAH patients and provide feasibility and safety research for further study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This is a pilot study of a single center, randomized, controlled trail.

Within 3\u202fdays of randomization, hyperchloremia occurred in 18\/30 (60%) patients in the BMES group and 23\/30 (76.7%) in the NS group (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.165, relative risk 0.58, 95% CI 0.27\u20131.28).
