Water for Injections q.s.

Indications

  • Management of diabetic ketoacidosis particularly in infants and children.
  • Prevention and management of contrast-induced nephropathy.
  • Management of acute renal failure secondary to rhabdomyolysis.
  • Environmental emergencies such as heat stroke.
  • Used as a vehicle for medications such as sodium bicarbonate in severe metabolic acidosis and magnesium sulphate in the management of preterm labor.

Dosage and Administration

Nisf Normal Saline should be administered according to the clinical condition of the patient, age, and body weight.

For management of contrast-induced nephropathy, 0.45% saline is infused at a rate of 1 ml/kg/hour. Infusion is started 1-2 hours before contrast and continued for up to 24 hours, depending upon the duration of diuresis attained.

In the management of acute renal failure secondary to rhabdomyolysis, in adults, 1000 ml. of 0.45% saline is used to dilute 44 mEq. of sodium bicarbonate and infused at the rate of 100 ml/hour.

Duration of Action and Excretion

Passes out of the bloodstream quite rapidly, especially when normal renal function and renal blood flow are present.

Adverse Effects
