LR vs NS

emDocs - August 30, 2021 - By Gabrielle Leonard and Aaron Lacy
Reviewed by: Alex Koyfman; Brit Long
Pearls:
  • LR composition is more similar to human plasma than NS.
  • LR is preferred to NS in select ED presentations, such as DKA.
  • LR will not worsen hyperkalemia and the acidosis from NS may in fact be more detrimental.
  • LR does contain sodium lactate but will not contribute to clinically significant worsening lactic acidosis.
  • NS is preferred to plasma-lyte in patients with TBI.
  • Consider NS when mixed with certain medications such as ceftriaxone or blood transfusions to avoid precipitation when only a single IV access site it available.
