- Intravenous fluid replacement (including hypercalcaemia or hyperchloraemic alkalosis): Treatment of choice for hypercalcaemia or hyperchloraemic alkalosis.
- Shock (rapid blood volume expansion): Use hypertonic saline. Must monitor serum sodium and follow with isotonic crystalloid.
- Corneal oedema: Use 5% hypertonic ophthalmic ointment.
- Hypoadrenocorticism (long-term management): Enteric-coated products may have unpredictable efficacy in dogs.

概覽
氯化鈉是一種基礎的晶體輸液，在獸醫學中用於液體補充、電解質平衡以及作為藥物稀釋劑。它有低張、等張（生理食鹽水）和高張配方。
臨床提示： 高張食鹽水是治療休克時強效的體積擴張劑，但需要仔細監測血清鈉濃度，並隨後補充等張輸液。
作用機轉
Isotonic and hypertonic formulations expand plasma volume and replace lost extracellular fluid. Hypotonic formulations provide free water and may promote oedema formation.
When used for fluid replacement, NaCl (0.45% and 0.9%) will expand the plasma volume compartment. → Compared with colloids, 2.5 to 3.0 times as much fluid must be given because the crystalloid is distributed to other fluid compartments.
安全性與警告
禁忌症
- Dehydrated animals (Hypertonic saline)
- Hypovolaemic animals (Hypotonic solutions)
不良反應
- Peripheral oedema
- Hyperchloraemic acidosis (especially in compromised patients)
- Vagally mediated bradycardia (if hypertonic saline is administered >1 ml/kg/min)
- Stinging sensation (ophthalmic ointment)
注意事項
Warning: Hypertonic saline solutions have very high sodium concentrations. Monitor serum sodium concentrations before and after administration. Maintenance with an isotonic crystalloid is usually required after administration to correct electrolyte and fluid disturbances.
Safety and handling: Hypertonic saline solutions should be regarded as drugs, not standard IV fluids, and stored separately to prevent confusion.
Clinical Pearl: Enteric-coated products for oral use may not be adequately absorbed by dogs, leading to unpredictable efficacy. Normal saline contains higher amounts of chloride than plasma, increasing the risk of acidosis.
監測
- Serum sodium concentrations (especially before and after hypertonic saline)
- Acid-base status (monitor for acidosis)
- Heart rate (monitor for bradycardia during rapid hypertonic infusion)
- Hydration status and fluid balance
藥物動力學
吸收
Enteric-coated oral products may not be adequately absorbed by dogs, leading to unpredictable efficacy.
分佈
Crystalloids distribute widely into extracellular fluid compartments; 2.5 to 3.0 times as much fluid must be given compared to colloids to achieve the same plasma volume expansion.
過量
Excessive administration of normal saline can increase the risk of hyperchloraemic acidosis and peripheral oedema. Administration of hypertonic saline at fluid rates >1 ml/kg/min can cause a vagally mediated bradycardia.

飼主須知
氯化鈉（生理食鹽水）通常用於為寵物補充水分、治療休克或處理特定的眼部疾病。如果您的寵物被處方口服鹽片或眼藥膏，請仔細遵循獸醫的指示。眼藥膏可能會引起輕微、暫時的刺痛感。請確保您的寵物隨時有乾淨的飲用水。
