Feasibility of 5% Albumin Compared With Balanced Crystalloid, as Intravenous Fluid Resuscitation in Adult Patients With Sepsis, Presenting as an Emergency to Hospital

The aim of this research study is to compare two different fluids (Human Albumin Solution (HAS) and Balanced Crystalloid that are given via a drip to patients with severe infection (sepsis). The investigators plan to see which fluid is better, and to see if they have a role in improving a patient\'s recovery time, reducing complications and the length of time they stay in hospital. This study plans to find out if there is evidence that one fluid is better overall to determine the need for a subsequent definitive trial.
