Sodium Chloride 0.9% Overview

Study Notes

Sodium Chloride 0.9% (Normal Saline - NS)

Classification: An isotonic solution, maintaining balance in fluid osmolality with body fluids.
Actions: Replaces fluids and electrolytes lost from both intravascular and intracellular compartments, supporting hydration.
Indications:
- Utilized for initial fluid replacement in cases of hypovolemia.
- Serves as an intravenous access line for medication administration.
- Infused into saline locks to ensure they remain patent.
Contraindications: Use with caution in patients exhibiting rales, indicating possible fluid overload or heart issues.
Adverse Effects: May lead to metabolic circulatory fluid volume overload, particularly in sensitive populations.
Route of Administration: Administered via intravenous (IV) or intraosseous (IO) routes for rapid intervention.
Onset: Provides immediate effects upon administration, allowing for quick stabilization in emergencies.
Duration: The solution remains in the intravascular space for less than one hour, necessitating timely reassessment.
Notes:
- In fluid resuscitation, continue infusing until signs of adequate perfusion are observed.
- Exercise caution with fluid administration in patients with congestive heart failure (CHF) or pulmonary edema, as it can exacerbate their condition.
- Also used as a flush for specific intravenous medications, including IV adenosine, to ensure compatibility and maintain line patency.
