Crystalloid FLUID Choices for Resuscitation of Hospital Patients

Salt fluids are used extensively for acutely ill patients who are admitted to hospital. Two salt fluids commonly used are Normal Saline and Ringer's Lactate. Both are used to rehydrate patients, restore fluid volume and help stabilize blood pressure and failing organs. Both salt fluids have been used for several decades. Until recently, it was thought the fluids are essentially equivalent other than some minor differences related to the concentration of salt components (sodium and chloride) and buffers (Ringer's Lactate has lactate as a buffer). Recent data suggest that salt fluids containing less chloride like the Ringer's Lactate, cause less acid in the blood, less kidney failure, and less death. However, the studies to date are small and weak in their design and it is possible that there are no important differences that affect patients. Hence, the research team will conduct a robust pragmatic clinical trial where several academic and community hospitals will be randomized to use either Ringer's Lactate only or Normal Saline only for a period of three months. The trial will yield high quality and robust data to determine if Ringers Lactate reduces death and re-admissions to hospital. Before embarking on this large-scale trial, it is important to conduct a smaller (pilot) trial to evaluate if the larger trial will be feasible and not too costly. In this small trial involving no less than 4 hospitals, the investigators will determine how well the fluid interventions are adhered to in each hospital, record how long it takes to receive approval from research ethics boards and be ready to start the study. The investigators will also record challenges and develop solutions related to the operations of the trial, and describe important clinical and outcome data essential for the design and planning of the large trial.
