lactated ringer maybe not better than normal saline


  • Meta analysis in 2019 found no mortality between crystalloid and colloid.1
  • Early meta analysis in 2019 found no difference between LR and NS. 2
  • SMART: A pragmatic study involving 15,000 patients at Vanderbilt found for sepsis, LR has much lower mortality (0.74, 95% CI 0.59-0.93), AKI, ventilator free days, RRT free days compared to NS. 3 4
  • Most recent Basics trial found no difference between LR and NS. 5
