This was a randomized clinical trial of over 2200 patients in 4 ICUs in New Zealand comparing 0.9% Saline (NS) vs Plasma-Lyte.  This trial had many issues including, >70% of patients coming from the OR, only 15% came from the ED, only 4% had sepsis, and the biggest issue with this trial was that the majority of patients only received 1 – 2L of NS, making it unclear if larger volumes of unbalanced crystalloid would have worsened morbidity and mortality.  Since the publication of this study, two more trials have been published: The SALT-ED Trial and The SMART trial (Both Just published in the NEJM Feb 27th, 2018).
