Use of infusion solutions

Choice of infusion solutions according to the indications

There is no justification for using more than 3 kinds of infusion solution:

- one kind for IV rehydration (ringer lactate is the most suitable);
- one kind for dilution of IV injectable drugs (isotonic dextrose solution is the most suitable);
- one kind for fluid replacement (best choice is polygeline).

FIGURE

Precautions for the use of infusion solutions

- Read the labels on the infusion bottle (or bag) well to avoid mistakes.
- Indicate on the label any drugs added to the infusion.
- If drugs are added in a vial, think of the risks of:

· physical or chemical incompatibility,
· contamination: strict asepsis.

- Inspect each bottle against the light to check its clarity: discard any bottles that show particles in suspension.

DEXTRAN (Macrodex(R), Rheomacrodex(R))
solution for INFUSION

District hospital

Preparation

- Bottle of 500 ml

Composition

- Dextran 40,000 or 70,000 (composition and concentration varies with manufacturer) in a sorbitol, glucose, NaCI or ringer lactate solution

- Restoring macromolecules and maintaining the blood pressure and volume. Fluid replacement in case of hypovolemic shocks: trauma, surgery and sepsis.

Contra-indications, side-effects, precautions, remarks

- Risk of inducing renal failure: do not exceed 1000 ml for an adult and/or 500 ml/d if the treatment has to be prolonged.
- Risk of haemostatic disorder.
- Risk of allergy.
- In case of dehydration, correct electrolyte imbalance.

DEXTROSE 5% = GLUCOSE 5%
isotonic solution in INFUSION

District hospital

Preparation

- Bottle/bag of 500 ml of 5%
- Bottle/bag of 1 litre of 5%

Composition

- Isotonic solution: dextrose 5 g per 100 ml

Indications

- Infusion medium
- Intra-cellular dehydration (rare): fevers, sunstroke

Contra-indications, side-effects, precautions, remarks

- This solution contains no electrolytes or lactate. Therefore it is not recommended for the treatment of dehydration. Preferably use ringer lactate. If this is not available, take a solution of dextrose 5% and add KCI (2 g/l) + NaCI (4 g/l).
- The solutions of dextrose 5% 1/2, 1/3 or 1/4 salted have the same indications and inconveniences as the isotonic NaCI solution.
- Do not confuse with the 10%, 15%, 30% and 50% hypertonic solutions.
- Storage: keep below 30°C

DEXTROSE 30 or 50% = GLUCOSE 30 or 50%
hypertonic solution in AMPOULE

District hospital

Preparation

Indications

- Energy supplementation (1 g dextrose provides 4 calories)
- Hypoglycaemia

Contra-indications, side-effects, precautions, remarks

- Do not administer hypertonic solution IM or SC. The injections must be given in slowly direct IV injection or in IV infusion.
- Storage: keep below 30°C

Half Strenght DARROW'S SOLUTION
solution for INFUSION

District hospital

Preparation

- Bottle/bag of 500 ml
- Bottle/bag of 1 litre

Composition

- Varies with manufacturer. Example (ionic composition per litre):
Sodium (Na+) : 61 mmol = 61 mEq

Bicarbonate : 27 mmol = 27 mEq

Indications

- Severe dehydration

Contra-indications, side-effects, precautions, remarks

- Isotonic solution without providing calories.
- This solution has the disadvantage of not providing enough NaCl, but the advantage of providing suitable quantities KCI. For prolonged use, double the amount or add 10% or 20%, NaCl by ampoule in order to obtain sufficient concentrations (1 ampoule per litre = 1 to 2 g NaCl).

Contra-indications, side-effects, precautions, remarks

-This solution combines replacement of electrolytes and macromolecules. It has almost no effect on haemostasis.
-Administer 1 or 2 bottles on average. Adapt dosage according to the needs of the patient.
-In case of haemorrhagic shock, infuse one after the other. If polygelines are not availabe, use ringer lactate, giving three times the lost volume.
-For other forms of shock, infuse quickly until a good pulse reappears.
-Risk of allergy.
-Draw blood for type and cross-match before infusing.
-Do not dilute other drugs into this type of infusion.

RINGER LACTATE = COMPOUND SODIUM LACTATE SOLUTION = Hartmann's solution
isotonic solution for INFUSION

District hospital

Preparation

- Bottle/bag 500ml
- Bottle/bag 1 litre

Composition

- Varies with manufacturer
- Most usual ionic composition per litre:
Sodium (Na+) : 130.50 mmol = 130.50 mEq

-Ringer lactate provides appropriate quantities of electrolytes. It contains lactate which transforms into bicarbonate in the body and corrects metabolic acidosis if it exists (if haemodynamic and liver function are normal). WARNING, SOME COMMERCIALLY AVAILABLE SOLUTIONS DO NOT CONTAIN LACTATE.
-It does not contain much KCl (5 mEq/litre), but sufficient for short term use. For prolonged use (after 2 to 3 days), a supplement of potassium is necessary. Add 1 or 2 g KCl per litre = 1 to 2 ampoules of 10 ml KCl 10%/litre.
-For moderate and mild dehydration, administer ORS (Oral Rehydration Salts).
-This solution can be used for haemorrhagic shock. In that case, 3 times the lost volume has to be infused.
Storage: keep below 30°C
