I dilute everything, if possible, but IV Valium is definitely an exception. if you want to see the crystallization in action- (next time you give some and have some to waste)- take the wasted part and add some saline to it. It immediately becomes cloudy. Definitely don't want to give that to the patient. For admin- I generally unhook the line and push it directly into the saline well. Then reconnect the fluids or flush out. It shouldn't burn that much to my knowledge- I have never had anyone c/o Valium burning. Any questions, I like to call our pharmacy. They're really helpful.

The few times, that I had IV Valium (used in endo in the old days), it stung but was tolerable. However, the site was painful for a week after or more.
Valium and NS have a different pH, hence the crystalization. Valium should be given undiluted. In fact, I have slight OCD and even put a tiny air bubble in the saline lock before and after I administer Valium so the saline will have no chance of mixing with the Valium. I have never had anyone complain of burning at their IV site with this medication or lost an IV.
This came up where I work as well. The policy that came out in the end was to continue to use IV valium for DT's. IM valium has not been shown to be effective when treating DT's, and lorazepam is not the preferred drug for DT's due to it's half-life, as well as studies of the outcomes of DT patients medicated with lorazepam vs. diazepam.
Our policy is to dilute it. While it may form a precipitate, that's actually OK:

IV valium has a low solubility in NS and other IV solutions, which is why the IV solution is 40% propylene glycol. Once it meets blood however, it re-disolves. The reason why we our policy is to dilute it is that undiluted valium, with it's 40% antifreeze (propylene glycol), has a significantly higher risk of causing cardiac adverse effects (asystole).

Good day everyone. I have a question that may seem simple but i am spinning my wheels trying to get an answer i am comfortable with. I know what my IV bible says and states about giving Diazepam IV. I happen to like to dilute my drugs if possible. Book says not to dilute because of crystalization/etc. in the line. It is to be given at the port closest to the pt and to give a specific amount over 1 miniute. If this is not diluted it burns really bad going in, no matter how slow it is given, and if it is given closest to the pt it is being diluted no matter what unless the line is pinched off, drip is stopped etc. Let me communicate first that the IV's and line I am talking about are in no longer than 3 hours max. Can an experienced nurse or nurses out there please help me to understand and share your experience with this if you have it?? Yes, I am a new nurse (in my book) and i am looking for input. Thank you so very much in advance.
