Pediatrics Med calculation

[xxiangel]

Hi guys,

I am having trouble coming up with the answer to this problem.

You have a Morphine drip running at 0.8 mg/hr. The concentration of the drip is 2 mg/cc. How many ml/hr should the pump be running at? Therpeutic dosage for a morphine drip is 0.02 mg/kg/hr. The patient weighs 37 kg. Is this an appropriate dosage for this patient? The patient wakes up and begins thrashing about. The physician tells you to give the child a 0.1 mg/kg bolus. How many mg do you give the child?

-------------------------------------------------

I got the ml/hr the pump is supposed to be running at, which is 0.4 ml/hr.... I divided (0.8 mg/hr / 2 mg/cc ) to get the pump rate. I believe that is correct but I am having trouble determining if this is an appropriate dosage or not and how to determine the mg for the bolus. Thanks so much for helping me with this!

I have never heard of a pedi patient on a morphine drip.

you are being asked to determine a weight based dose for this patient. weight based dosing can either be order per hour (as this one is) or per minute. to calculate a weight based dose (per hour), i use the following formula: dose x weight.

if you wanted to determine the infusion rate, then you need to add an additional step and include the concentration. in that case i would use the following formula: (dose x weight) / concentration of the infusion.

when using any formula, it is important to remember that all units must be expressed in like increments.

i have never heard of a pedi patient on a morphine drip.

although fentanyl is the primary analgesic infusion in the picu where i work, we occasionally use both morphine and hydromorphone.

An adolescent (big kid to boot) s/p MVA... I could see it :)
