Step 1: Take the patient's weight in

**pounds**, and drop the last digit

Step 2: Subtract 2 from the remaining number

Your final number, is the dosing for 5mcg dose for that patient in gtts/min of mL/hr

Let's do a few examples:

Example 1: Patient Weight = 210

210 ---> 21

Example 2: Patient Weight = 128 pounds

128 ---> 12

Example 3: Patient Weights = 62 kilograms

62 x 2 = 124 ----> 124 + 12 = 136 --------> 136 pounds

*(take 10%)*

136 ---> 13

Now let's say that you want to give the dose as 10mcg. All you do, is figure out the dose for 5mcg, than double it.

Example: Patient Weight 100 pounds

100 ---> 100 ---> 10-2 = 8 --------> 8gtts/min for 5 mcg dopamine dose

8 + 8 = 16 ------> 16gtts/min for 10mcg dopamine dose

Let's figure out the dose for dopamine, and the drip rate for dopamine for a patient.

Patient Weight: 150 pounds (68 kg)

Dopamine Supplied: 2-20 mcg/kg/min

Drip Rate: 10mcg

1) 10mcg/kg/min x 68 kg = 680mcg

2) 150 ---> 150 ---> 15-2=13 --------> 13gtss/min of 5mcg dopamine dose

3) 13gtts/min x 2 (double) = 26 -------> 26gtts/min dopamine dose

You would give you patient 680mcg of dopamine, with a drip rate of 26gtts/min.

Do you have any tricks for getting drip rates for other dosages of dopamine such as 4mcg/8/9/15 ect but using that same method

ReplyDeleteHow does 8x2=14 and how is 10mcg a Drip Rate? Not to get too picky, but in all of this, you have yet to specify what drip set you are using

ReplyDeleteI'm willing to guess that the 8x2=14 is a typo. It happens. And dopamine is usually hung with a 60 drop set.

DeleteCool. Thanks for replying

DeleteHello everyone. Sorry for the late reply, I work three jobs and do not always get to check this email everyday.

DeleteYou guys are correct, that was a typo. I will make the correction.

Once you figure out the 5mcg dpse, you just have to double that dose for you 10mcg. That tootal would be 16 mxg, because you are doubling the "8."

As for the gtts set, the formula works for any drip gtts, however the most commonly used gtts set is 60.

This also only works for a 1600 concentration

DeleteThis also only works for a 1600 concentration

DeleteAnd only for 60 drop set

ReplyDeleteYou do know that 21-2 is 19 and not 18 right?
