The investigators plan to study the impact of giving patients with severe infection intravenous fluids with either a high chloride concentration (normal saline or high chloride albumin) or a low chloride concentration (Ringers Lactate or low chloride albumin). Although, the investigators plan for a larger trial looking at patient-important outcomes such as rate of death, kidney failure and length of stay in the ICU the investigators think it's important to start with a feasibility study. If the investigators are able to show a larger trial is feasible then the investigators will apply for further funding and use the lessons learned from this pilot to optimize the larger study. The larger study has the potential to guide the care of critically ill patients with infection worldwide.
