Intravenous injection

In many respects the administration of medicines via the IV route is an admission that the use of other routes will not allow for an intended therapeutic outcome or goal of the treatment to be met. Not only is the route inconvenient for the patient and practitioner, but it carries the greatest risk of any route of drug administration. By administering directly into the systemic circulation either by direct injection or infusion, the drug is instantaneously distributed to its sites of action.

Such administration is frequently complex and confusing. It may require dose calculations, dilutions, information to be gathered on administration rates and compatibilities with other solutions, and the use of programmable infusion devices.

Moreover the preparation of medicines requires the use of an aseptic technique, often in a ward environment that is unsuited for such work. It is imperative that to minimise the risk of errors occurring in the administration of medicines that practitioners can demonstrate their competence to practice safely in this area, and have access to appropriate sources of expert information and advice.

Considerations when preparing an intravenous injection or infusion

Is the drug suitable for preparation at ward level or should it be prepared in pharmacy?

Does the drug require initial dilution?

If so what diluent is required and in what volume?

Does the drug require further dilution?

If so to what volume and with what diluent?

Is the drug suitable for direct injection or must it be infused over time?

What length of time can it be administered over?

Is an infusion device required?

Is the drug compatible with other drugs or fluids to be administered at the same time?

Does the drug cause any local reaction when given?

Is any monitoring required during or after administration?
