Just a couple of points. My wife and I are both pharmacists at two different hospitals and have enjoyed the podcast for over two years. Regarding TPA, pharmacists at both of our hospitals are responsible for mixing TPA on stroke patients. Also of note supposedly the manufacturer’s of TPA have told my wife’s hospital they will stop reimbursing for drug not used due to the high frequency of wasted drug at their hospital ( neither of us have ver hear it straight from the drug company but wanted to relay that possibility out to the audience.) Reference your site all… Read more »
Ryan, Thanks so much for those comments. I’m glad we have pharmacists following the site in case I stick my foot in my mouth with any med mistakes.
I’m glad you commented on mcg/kg/min vs. mcg/min for adrenaline, noradrenaline, dopamine etc. I started my ICU life in New Zealand where we used mg/h for vasopressors and inotropes, without a weight adjustment. I then moved to NSW, Australia where all the hospitals I’ve worked in thus far use mL/h. However some hospitals use a 4mg/100mL concentration and others use a 6mg/100mL concentration. But wait, there’s more. Once you reach about 40mL/h we switch to “double strength” (8mg/100mL) and then “Quad strength” (16mg/100mL). While this increased concentration makes the nurse’s life easier, and I guess gives everyone an indication that… Read more »
Great point on look-alike vials, will have to do a part III as well
Great podcast. I’m curious on what your thoughts are on how pediatric resuscitation dosages play into this….in all the prehospital services I’ve worked for, meds are packaged according to standard adult doses, I’m assuming in part to help reduce medication errors. However, this leads to problems with the rare (thankfully) pediatric resuscitation…I’ve been involved either directly or indirectly with medication errors involving weight-based pediatric doses during these cases. I’ve been a proponent of ditching preloads for multi-dose vials to force providers to use weight-based math for all patients as a strategy to prevent these errors, based on the assumption that… Read more »
will post one tomorrow
I wanted to point out a need for the 1:1000 vial of epinephrine. I think it may be different in other countries but racemic epinephrine is no longer available in Canada. For nebulized epinephrine for stridor, we occasionally need to give 5mg of 1:1000 epi.
Great point. That would be one which I would not mind ordering from pharmacy, as the 5 vial thing is already dangerous if given IV rather than via neb.
Epinephrine:
“Why are premix bags not readily available everywhere? – Bryan outsources for 6.25mg in D5W 250ml (25mcg/ml) and 2mg in D5W 250ml (6mcg/ml)”
For the latter concentration, 2 mg per D5W 250 ml, I get 8 mcg/ml and not the 6 mcg/ml quoted.
Thanks for clarifying,
Lyne
I agree Lyne, even pharmacists can make errors : )
Great session and I look forward to part II. Just a quick reference, if one goes to activase.com they can request tpa dosing cards for free. The cards have the info in columns and dosing is calculated across the window as you pull the inner card out finding the weight. We stick one in each of our stroke packets.
Great tip; they have a mixing video as well
I think Joe Lex gives a pretty reasonable and believable explanation of drug shortages in AAEM lectures from 2013 – found it on emedhome, little more info than what Bryan says…
This avoiding errors podcast very timely.
Regarding Pedi aspect mentioned above – “The Broslow guy” is obviously way deep into this. Special program (for institutions) but also an app that is about 10 bucks for android device. Another – Pedistat – very slick – I am frequently double checking myself with both of these.
Cheers
Just watched Joe’s lecture–kicked butt as usual.
Can you please explain how giving insulin vs subcutaneous is different? I know IV has a shorter duration, but why does it not affect the glucose as much as giving subcutaneous? What is the reasoning behind this? Thanks!
I’m asking the same question as Jeremy above.Maybe I just misunderstood how the question was proposed. I interpreted as though mechanism was different. I’ve searched and can’t find this anywhere. I was under impression subc was less accurate due to varying absorption compared to IV. Please enlighten me. Also, thanks for swinging through Columbus. Thoroughly enjoyed your forum! Thanks!
Jeremy and Leighann, glucose transporters are maximally filled at a dose of 1 units/kg/hr IV infusion. Anything beyond this is just wasted insulin from the glucose-lowering perspective. An IV push dose brings plasma levels way beyond this point and most of that insulin is wasted and the duration of action is much shorter than a sub-q dose that mirrors the IV infusion. For Hyper-K however, you are trying to activate the Na-K-ATPase, which have a much higher requirement of insulin for maximal activation (i.e. maximal lowering of K). Leighann–in the critically ill, an IV INFUSION, is considered to be more… Read more »
Thanks for the explanation!
Trying to find the source for the 1 unit/kg/hr statement and am having a hard time. I’m just now trying to convince my doctors in ER to switch to subcutaneous administration vs. IV. Thanks!
epi is pretty stable in syringes. I’m aware of a outdoor program that replaced epipens with prefilled syringes Here are two good papers on the topic.

great info!
Another excellent episode, I look forward to part II! This is a topic that interests me greatly and I’ve been seeking thoughts and opinions on a project I’ve been working on. It’s a “dynamic” PDF that uses JavaScript to automatically calculate drug dosages once a patient weight has been input. This particular prototype is designed for pediatric drug dosages, but there’s logic built in so it doesn’t exceed maximum doses (or minimum doses, in the case of Atropine) if you reach adult weights, and after selecting age range from a drop-down it automatically selects the proper Dextrose concentration as described… Read more »
Holy crap; that is totally bad-assian. I love it. If it had a few more drugs like propofol, etc. this would be a go to item for me. Strong work.
Thanks for the kind words, I think it’s got potential. I’ll start throwing together an adult prototype for use at Janus General Hospital!
Great write up by Bryan! Just as a precautionary point…insulin can bind to the surfaces of the IV bag and tubing- especially with conventional PVC material. This would not be so much an issue with insulin infusions for DKA patients where higher concentrations (100 units/100mL at our institution for adults) are used to titrate blood glucose. For hyperkalemia, I feel that shooting 10 units regular insulin into a D10 500 mL bag can have significant losses with a smaller unit amount of insulin per volume. By the time the bag is primed and infusing into the patient, we aren’t very… Read more »
Paul, we address this exact topic in part II, when we discuss insulin drips. I too prefer the straight-up insulin push and D50 push.
This is the second pod I listened. Was really useful. Thankyiu and keep it carry on.
Thanks for another great post Scott I have a late comment in favour of using IM adrenaline (or epi) in anaphylaxis. When these cases come in I let the nurse and resident scramble around trying to get in a hurried IV while I draw up 300-500mcg of 1:1000 adrenaline and give it IM. By the time the IV is in most patients are feeling better and the danger has passed. The can have a bit of fluid and some top up adrenaline I required. And in favour of 1:1000, the main thing I can think of is that it might… Read more »
sure, no IV go IM. I’d like to see some legitimate studies demonstrating the benefits of nebulized adrenaline.
I am a pharmacist that has worked in the ED in Alberta, Canada for 10+ years now. I am catching up on these podcasts and I downloaded this one first, looking forward to the discussion with Brian D. Hayes. I have to say I was VERY disappointed that Brian generalized and blasted research where pharmacists were involved, stating, “anytime you are looking at a study like this where pharmacists are involved you know there is going to be a little bit of bias, because we are always looking for ways to increase our presence to add more positions and justify… Read more »
Steve, Thanks very much for your comments. You are absolutely right in the benefits that pharmacists provide. It has been demonstrated in ICUs, general medical wards, EDs, clinics, etc. My words on the podcast may have come out not exactly as I intended and I appreciate you pointing it out. These studies are critical to growing the profession of pharmacy. We cost a lot, and need as much justification as possible to ensure expansion in various hospital areas. In fact, I am using these same studies (and a recent one in CJEM) right now as I try to add more… Read more »
Thank you, I appreciate your reply, Brian.
Do you have a reference for the statement regarding an incidence rate of 75% of pts become hypoglycemic from IV bolus insulin / dextrose? We are re-evaluating our protocol in the ED and I would like some supporting literature.
