Podcast # 472: SMART Crystalloids

Author: Gretchen Hinson, MD

Educational Pearls:

  • In most healthcare settings, normal saline (NS) has become ubiquitous as an intravenous fluid despite some potential drawbacks
  • Compared to normal saline, a balanced crystalloid (either lactated Ringer’s or Plasma-Lyte) was associated with a lower composite endpoint of mortality, renal replacement therapy, and renal injury in SMART (Isotonic Solutions and Major Adverse Renal Events Trial)
  • Balanced crystalloids such as lactate Ringer’s may be preferable in more critically ill populations
