Impact of Intraoperative Fluid Management on Electrolyte and Acid-Base Variables During Posterior Spinal Fusion in Adolescents.

The use of NS for intraoperative resuscitation during posterior spinal fusion in adolescents resulted in a greater base deficit and a lower pH than the use of LR or NR. Although these changes had limited clinical significance in our patient population, future studies are indicated to further investigate the potential clinical impact of these changes.
