Comparison of the Effects of Fluid Therapy With Normal Saline, Ringer, and Ringer’s Lactate During Anesthesia on the Hemodynamic Status and Events During Orthopedic Lower Limb Orthopedics Surgeries

Abstract

Objectives: Given that no study has so far carefully examined the effects and benefits of crystalloids on the hemodynamic status and events during the surgery for lower limb orthopedic surgeries, the current study aimed to compare fluid therapy with normal saline (NS), Ringer (R), and Ringer’s lactate (RL) during anesthesia on the hemodynamic status and events during lower limb elective orthopedic surgeries. Materials and Methods: This cross-sectional descriptive study was conducted in 2019 with the participation of 270 patients (three groups each including 90 subjects) who were scheduled for an elective lower limb orthopedic surgery in Imam Reza hospital of Tabriz. Patients received one of these serums of NS, R, and RL. Electrolytes were measured before and after the surgery. Finally, data were analyzed using ANOVA and chi-square tests. Results: Based on the results, there was no significant difference between the three groups in terms of hemoglobin, hematocrit, sodium, calcium, potassium, chlorine, albumin, creatinine, urea, bicarbonate, pH, and arterial oxygen levels (P>0.05), and RL serum had the least effect on all factors. Conclusions: In general, the administration of NS, R, and RL in lower limb orthopedic surgeries did not result in significant differences although RL had the least adverse effects and was associated with better results.
