Baxter Lactated Ringer's Injection IV Solution USP 500mL

Why Choose Baxter Lactated Ringer's Injection USP?

Lactated Ringer's (LR) is one of the most widely used balanced crystalloid IV solutions in clinical medicine, and for good reason: its electrolyte composition closely approximates the electrolyte content of blood plasma, making it physiologically more compatible with human fluid than normal saline for most fluid replacement indications. Where normal saline provides only sodium and chloride at supraphysiological chloride concentrations, Lactated Ringer's provides five key electrolytes — sodium, potassium, calcium, chloride, and lactate — at concentrations that more closely reflect the body's natural fluid composition. The lactate component is metabolised by the liver to bicarbonate, providing a buffering capacity that helps maintain acid-base balance during and after fluid administration. At an osmolarity of approximately 273 mOsm/L — slightly hypotonic relative to plasma — LR is well tolerated for large-volume replacement in a broad range of indications including post-surgical fluid management, trauma, burns, dehydration, and general perioperative hydration. Baxter's VIAFLEX flexible IV bag system is a closed, sterile, non-pyrogenic, preservative-free container ready for direct IV administration. Typically packaged 24 bags per case.

Clinical & Typical Applications

Post-surgical fluid management in recovery and perioperative settings where balanced crystalloid replacement is indicated

Trauma, burns, and haemorrhage management where large-volume crystalloid resuscitation requires a physiologically balanced solution

Dehydration and fluid deficit correction in medical and emergency settings where electrolyte replacement is required alongside volume

General IV hydration maintenance in medical-surgical, ICU, and emergency settings

Electrolyte imbalance correction where sodium, potassium, and chloride repletion is indicated alongside volume replacement

Intraoperative fluid management in anaesthesia where a balanced crystalloid is preferred over normal saline
