Normal Saline
Free!
Normal Saline is a sterile, isotonic 0.9% sodium chloride solution used for IV hydration, volume replacement, medication dilution, and procedural irrigation. It’s clear, single-use, and compatible with many drugs, making it a dependable choice across emergency, ward, and outpatient settings. Chosen for predictable performance and easy handling, it helps clinicians restore fluid balance quickly while supporting everyday infusion and flushing tasks.
Description
Normal Saline is a sterile, non-pyrogenic 0.9% sodium chloride solution in water. It is isotonic with human plasma, delivering approximately 154 mEq/L of sodium and 154 mEq/L of chloride for rapid extracellular volume expansion. Hospitals, clinics, and emergency responders rely on this versatile crystalloid for routine hydration, fluid resuscitation, and as a compatible vehicle for many injectable medicines.
Key features and benefits
• Isotonic 0.9% NaCl for predictable fluid replacement
• Sterile, single-use presentation to reduce contamination risk
• Compatible with a wide range of IV drugs for dilution and reconstitution
• Clear solution in tamper-evident bottles or flexible infusion bags for easy visual inspection
• Suitable for venous infusion, line priming, catheter flushing, and procedural irrigation
Common uses and applications
• Treating dehydration, hypovolemia, and perioperative fluid loss under clinician supervision
• Initial resuscitation in emergency care when a balanced crystalloid is not immediately required
• Diluent for IV medications and antibiotics as directed by protocols
• Irrigation of wounds and surgical fields; rinsing and priming IV sets
How it compares
• Versus balanced crystalloids (e.g., solutions containing buffers and electrolytes), Normal Saline is widely available and drug-compatible but lacks buffers and potassium; large volumes may increase chloride load.
• Versus half-normal saline (0.45%), it provides better intravascular expansion.
• Versus hypertonic saline, it is safer for routine volume replacement.
Quality and handling
• Produced as a sterile aqueous solution and filled in sealed, latex-free containers.
• Free from antimicrobial agents; discard any unused portion.
• Store as labeled; use only if the solution is clear and the container is intact.
• Use with caution in patients with heart failure, renal impairment, or when sodium restriction is required; clinical supervision is essential.
