[Should we switch from saline to lactated Ringer's solution? Limited benefits, medication warning system required]

Area of Science:

• Medical Science
• Pharmacology
• Clinical Practice

Context:

• Growing advocacy for balanced crystalloid solutions, such as lactated Ringer's, over normal saline for non-critically ill patients.
• Current evidence suggests limited benefits of lactated Ringer's solution compared to saline in both critically and non-critically ill populations.
• Lactated Ringer's solution exhibits incompatibility with blood products and commonly used intravenous drugs, unlike normal saline.

Purpose:

• To evaluate the comparative benefits and risks of lactated Ringer's solution versus normal saline in fluid therapy.
• To highlight the drug-Lactated Ringer's solution incompatibility issues and the need for precautionary measures.
• To assess the feasibility and safety requirements for a hospital-wide transition to lactated Ringer's solution.

Summary:

• While a shift to lactated Ringer's solution may benefit some patients, its incompatibility with essential medications requires careful consideration.
• Implementation necessitates robust medication warning systems to mitigate risks associated with co-administration of drugs and lactated Ringer's solution.
• The evidence for significant clinical advantages of lactated Ringer's solution over normal saline remains limited.

Impact:

• Informing clinical decision-making regarding fluid therapy choices between balanced solutions and normal saline.
• Guiding hospital pharmacy and therapeutics committees on safe medication management practices during crystalloid fluid transitions.
• Highlighting the importance of integrated medication safety systems for optimizing patient care in fluid resuscitation protocols.
