Brief summary

0.9% saline has been used in clinical practice for fluid resuscitation and general fluid therapy since the 1880s. While it is the most commonly used IV resuscitation fluid in the world, some data raise the possibility that using 0.9% saline for intravenous therapy may be related to altered gastrointestinal (GI) function .Current data are insufficient to recommend clinical practice change and further data from an interventional trial are urgently needed. However, the design of such a Trial requires sufficient pilot data to establish feasibility, safety, power calculations, and define an optimal study protocol.

Interventions

This study is conducted as a single centre nested cohort study within the SPLIT study (0.9 % Saline versus Plasma-Lyte (Registered Trademark) 148 for Intensive Care Fluid Therapy). Intervention = Plasma-Lyte (Registered Trademark) 148, this will be given at intravenously at the discretion of the treating clinician during the ICU stay.

This study is conducted as a single centre nested cohort study within the SPLIT study (0.9 % Saline versus Plasma-Lyte (Registered Trademark) 148 for Intensive Care Fluid Therapy). Intervention = Plasma-Lyte (Registered Trademark) 148, this will be given at intravenously at the discretion of the treating clinician during the ICU stay. Fluid will be given in alternating seven week blocks. Any patient who remains in the ICU after a crossover period will continue to receive the study fluid to which they were originally assigned up to 90 days after enrolment. As a result, no washout is required between cross-over periods. The treatments will be administered ‘blind’ to both investigators and patients. Patients enrolled into the SPLIT study, expected to be mechanically ventilated for longer than 48 hours, and receiving enteral nutrition via nasogastric tube will be eligible for this pilot study. During the study period the intensive care unit will be randomly assigned to a 7 week period of administration of trial fluid. There is a double crossover approach so that the each strategy is given twice.
