Acquired hypochloraemia

The absence of a significant hypochloraemia association differs from some prior research in heart failure, continuous renal replacement therapy, and community-based hypochloraemia. Acquired hypochloraemia was defined as normal chloride at ICU admission followed by hypochloraemia 48 hours later. Sensitivity analyses did not find a significant mortality association for acquired hypochloraemia. Acquired hypochloraemia was not significantly associated with in-hospital mortality after adjustment.
