Medications Via Piggy Back

Administration of Medications via Piggy Back
.
.
Frequently, medications are given at scheduled intervals (e.g., twice daily) using a separate premixed IV bag and additional IV tubing connected to an existing IV infusion. This method of administration is referred to as “IV piggyback” (IVPB) or a superimposed infusion.

It may also be called a small-volume parenteral delivery system, a partial fill, or a minibottle. The client receiving a piggyback administration of medication also has a “primary” IV, which is usually one of the more commonly ordered IV solutions (e.g., normal saline—0.9% NaCl). A small bottle delivery system may also be delivered into a saline lock.

This image shows a basic intravenous (IV) setup includes tubing to deliver basic IV fluids via the client’s venous access. Also shown are the access port on the tubing, used for injection of small amounts of medication by syringe (below) and the access port used for piggyback administration of larger amounts of medication (above).

These needleless ports prevent needlestick injuries to staff. (Blood and total parenteral nutrition [TPN] are administered through a different type of IV tubing.
