primacor:
pt is 51 kg. primacor 0.375 mcg / kg / min
the usual dilution of primacor is 200mcg/ml in pre-filled bags. also, keep in mind that the dose desired here is a complex fraction (0.375 mcg/1 kg/ 1 minute) so we have to do some mathematical manipulation in working out the problem properly. by dimensional analysis you want to end up with ml/hour (to program into the iv pump).
0.375 mcg/1kg (dose desired) x 1/1 minute (reciprocal fraction of denominator in dose desired--i am doing this to clear it out of the denominator) x 95 kg (patient's weight) x 1 ml/200 mcg (dose on hand--mixture of primacor on hand) x 60 minutes/1 hour (conversion factor) = 10.91 ml/hour which rounds off to 11ml/hour which is what you would set the iv pump to.
dobutamine:
pt is 97 kg. dobutamine 2.5 mcg / kg / min
dobutamine can be mixed in a different concentration depending on what the nurses generally like to use. all i can do is compute to mcg/minute for this patient. to determine the rate of infusion, you need to know what the dilution of the iv mixture of the dobutamine is and apply it to the mcg/min answer i have given you applying a conversion factor, as i did above, to covert from ml/minutes to ml/hours for setting the iv pump.
2.5 mcg/1kg (dose desired) x 1/1 minute (reciprocal fraction of denominator in dose desired--i am doing this to clear it out of the denominator) x 97 kg/1 (patient's weight) = 242.5 mcg/1 minute (delivery rate)
