![]() You just divide the desired dose by the amount on hand. In this example, the concentration is 50mg/ml. Your medical control orders you to give 25mg of Diphenhydramine to your patient having a mild allergic reaction. Just go slow, repeat these exercises as often as you need, and continue until you really have this down! It isnt something you learn once and you’re done…Its something you will want to review on occasion to maintain proficiency. ![]() MAKE SURE YOUR grams, milligrams or micrograms are the same! SOLVE THE CONCENTRATION, THEN DIVIDE THE DESIRED DOSE BY THE CONCENTRATION. In this next exercise, we’re going to draw up some medications and give you some practical situations to practice on! This stuff is important! Practice until you’re a bad ass… So now you know that pushing ‘1 amp’ of Bicarb in a 220 lb patient who needs it is only HALF of the dose he needs! AND YET THIS IS FREQUENTLY all they will ever get, because his paramedic didn’t know what you now know! So for the same 220 lb patient, you’re going to change the pounds to kg. You’re still going to multiply the dose times the number of kilograms and bring down the measurement… Sodium bicarbonate standard dose is 1 meq/kg (1 milli-equivalent per kilogram) It can be grams, micrograms, milliequivalents or any other measurement, but it works the same way. ![]() So, your desired dose for this patient is 100mg. So your patients weight is 100kg, and your order is for 1 mg for every kg. Your patient weighs 220 pounds.įirst, change your weight to kg: 220/2.2 = 100. Your order is to give Succinylcholine at 1mg/kg. When there’s a ‘mg/kg’ it is read as ‘milligrams per kilogram’ which means ‘FOR EVERY KILOGRAM that the patient weighs, you’re going to give X amount of milligrams.’ If the patient weighed 10kg, and the order was for 1mg/kg, the total desired dose would be 10 mg. Ok, now we’re going to do the very basics of weight-based drugs.
