Modeling the effect of high dead‐space syringes on the human immunodeficiency virus (HIV) epidemic among injecting drug users Bobashev, Georgiy V.; Zule, William A. Addiction, 2010, Vol.105(8), pp.1439-1447, 2010 A vial labeled to contain 1 gram of Cefazolin Sodium (as described in its USP monograph) is -10% to +15%. While it is likely that not all vials fall at the ends of this range, the best we can know is that the vial itself contains somewhere between 900 mg and 1,150 mg. It seems likely that vendors generally err on the heavy side of that equation, but the likelihood that a vial contains exactly 1 gram is small. The most accurate syringe in common use has an accuracy of ±4% when its nominal volume is 5 mL or greater when delivering at 50% or more of its nominal volume.

Adaptor: This is the area where you screw on a needle (if you were giving an intramuscular injection etc.) or onto the IV hub of the patient’s IV to give a medication. Conventional high dead space syringes have existed since the mass production of plastic syringes with removable needles in 1961. [3] The reality from ISO7886-1, however, is that delivering 9.6 mL from a 10 mL syringe has a ±4% precision, which means that we only know for certain that we delivered somewhere between 9.22 and 9.98 mL of diluent. Presuming the expansion from 9.6 to 10 mL is roughly linear within this narrow range, that means that our resulting volume is somewhere between 9.6 and 10.4 mL, so our concentration is somewhere between 86.5 mg/mL (900 mg/10.4 mL) and 119.8 mg/mL (1,150 mg/9.6 mL). Tip: If you hear someone say give “10 cc” of this medication, cc is the same as mL. Therefore, 10 mL equals 10 cc.

This is a 10 mL syringe. Each line measures in 0.5 increments until it reaches a total capacity of 10 mL. What this, in turn, should teach us is that the accuracy with which we prepare a dose depends entirely on the tools we use to physically measure the compounds that go into the dose. For IV admixtures, these consist of sterile disposable syringes, vials of drugs, and IV bags. Rannou, M. Lheureux, N. Prangere, T. Legrand, J. Huglo, D. (2012) Absorption of radiopharmaceuticals to plastic syringes: Measurement and consequences. European Journal of Nuclear Medicine and Molecular Imaging. (39)S528-S529. You can’t make a measurement more precise by performing arithmetic on it (you can’t weigh 1000 items on a scale accurate to the nearest gram and produce an accurate weight to the microgram level).

Differences from high dead space syringes [ edit ] Example a low and high dead space syringe and the average fluid remaining after complete depression of the plunger. The other thing worth noting is that if and when we get cost-effective end-product testing in the IV room, we are likely to have to set some pretty broad standards for what is acceptable, because there is a lot of variance we just cannot control.The fact that you can move the plunger in a syringe to a particular mark on its scale does not necessarily mean you are accurately measuring that amount, especially at the lower end of the scale. Products and replacement parts for use with laboratory syringes; includes syringe caps, tubing, cleaning products, and replacement parts such as needles, barrels, and plungers. a b c Modeling the effect of high dead‐space syringes on the human immunodeficiency virus (HIV) epidemic among injecting drug users. Addiction [0965-2140] Bobashev yr:2010 vol:105 iss:8 pg:1439 -1447 According to WHO guidelines for people who inject drugs it is suggested that needle exchange programs provide low dead space syringes for distribution to people who inject drugs due to evidence that the provision of low dead space syringes leads to a reduction in the transmission of HIV, and hepatitis B and C. [10] [11] Benefits of low dead space syringes [ edit ] This is a 100 unit insulin syringe. Each line measures in 2 increments until it reaches a total capacity of 100 units.

Adaptor: this is the area where you screw on a needle (if you were giving an intramuscular injection etc.) or onto the IV hub of the patient’s IV to give a medication. Therefore, I will be discussing how to read 5 different types of syringe you will encounter as a nurse, such as: Note that human error as not been accounted for at all in this process. Again, most of our measurements are likely somewhere between this range of values, but producing a dose at the edges of the range is quite possible. Note also that we have been living with this amount of variance for the over 40 years I have been in practice. If there is evidence that making the process more accurate produces better outcomes, I have not seen it. Tip: If you hear someone say give “10 cc” of this medication, cc is the same as mL. Therefore, 10 mL equals 10 cc. Reading a 10 mL Syringe At least some vials of Cefazolin 1 gram indicate that reconstitution with 9.6 mL of a suitable diluent produces a solution 10 mL of which contains 1 gram (100 mg/mL). Presuming a completely accurate delivery of that diluent (or, as our European colleagues call it, the solvent), that means that we know that we have somewhere between 90 mg/mL and 115 mg/mL concentration.

Given all the inherent error in the systems we operate, the best we can do is to operate those systems as best we can. This means: If we apply gravimetrics to the preparation process, and those gravimetrics correct the concentration computed for the vial based on detecting the addition of 9.4 mL rather than 9.6 mL, it is still only an approximation since we cannot know what was really in the vial in the first place, by a surprisingly wide margin. The range that was 830 mg to 1245 mg is reduced to 870 mg to 1200 mg. Since many gravimetric systems have an acceptable error in the ±5% range, there’s not much of this process they can ameliorate. What they can do is present evidence that suitable mass of something was transferred from one container to another. And that’s valuable.
