Overview
Normal saline (0.9% sodium chloride) injection is a sterile, isotonic solution used widely in veterinary medicine. It’s primarily used to restore fluid balance, rehydrate animals, and serve as a vehicle for other medications.
How It Works
Normal saline is an isotonic solution, meaning it has the same salt concentration as cells and blood. This property ensures it neither draws water into nor out of cells, maintaining balance and preventing cellular damage.
Uses & Indications
Normal saline is used for:
- Dehydration: Restores fluid levels in dehydrated animals.
- Electrolyte Balance: Maintains proper sodium and chloride levels.
- Medication Delivery: Serves as a carrier for drugs administered intravenously.
