There are three things to consider when prescribing an insulin syringe:
1. First, choose the syringe barrel based on the patient's dose.
Choose the smallest syringe that will hold the dose. The smaller the syringe barrel, the clearer the scale markings... a help to diabetes patients with vision problems.
|Use this barrel size...||With this dose range...|
|3/10 mL (cc)||30 units or less|
|1/2 mL (cc)||31 to 50 units|
|1 mL (cc)||51 to 100 units|
If the patient's largest dose is close to the maximum syringe capacity, choose the next syringe barrel size.
2. Second, choose the syringe needle length
BD offers a choice of lengths: 6mm (15/64"), 8mm (5/16"), also called "Short", and 12.7mm (1/2")
Many users feel that shorter is more comfortable.
Obese patients should test their blood glucose more frequently when switching from the 1/2" needle to the shorter 5/16" needle.
3. Then, choose the needle gauge.
The higher the gauge number, the thinner the needle. For example, a 31 gauge needle is thinner than a 30 gauge needle.
For patients using short needles and taking VERY small doses that are measured in half-units, prescribe the BD Ultra-Fine 3/10 mL (cc) Short Needle Syringe with half-unit scale markings.
