- Administer insulin and fluid infusions via the same cannula - See figure 1
- prevent inadvertent and dangerous administration of either insulin or glucose alone in the event of a blocked cannula
- Use a syringe pump for insulin
- Use a volumetric infusion pump for IV fluid
- to detect and prevent reverse flow of insulin into fluid-giving set in the event of restricted or occluded flow through the cannula
- on release of such a restriction, risk of inadvertent insulin bolus administration from the fluid giving set
DEFINITION
Anti-siphon check valve
- One-way valve that:
- prevents ‘reverse flow’
- with higher opening pressures to prevent inadvertent fluid flow caused by siphoning when tying into a higher flowing line
PROCEDURE
Insulin infusion
- Administer by a syringe pump via an infusion set with an anti-siphon valve
- to prevent inadvertent flow to patient from an unclamped or damaged syringe
IV fluids
- Run IV maintenance fluid via a volumetric pump to a Luer connector without a valve. See figure 1
Assembly
- See figure 1
- Drug infusion syringe to a line with an anti-siphon valve
- run infusion through line
- place syringe into syringe driver
- IV fluid to an administration set to a Luer connector without a valve
- run IV fluid through administration set
- place administration set in a volumetric pump
- Connect each into one of the double ends of a two-way needle-free extension set
- run IV fluid through extension set
- Connect the single end of the two-way needle-free extension set into the cannula
