milliunits

1 Can anyone provide help with the following med math problem:
Client is admitted to labor and delivery for a trial induction.
Order reads: Begin Pitocin at 2 milliunits per minute and increase by 1 milliunit every 15 minutes until 3 good contractions every 10 minutes.
Available: 500 mL of normal saline with 30 units of Pitocin.
What rate (mL/hr) should be set on the infusion pump to begin the infusion?
Thanks......

Jan 22, '08 by DaytoniteQuote from ljbutlerTo do this problem you need to know that Pitocin comes in 10 units per 1 mL and that when this 1 mL is added to 500 mL of IV solution it results in the solution containing 20 milliunits per mL of the IV solution (Reference: page 958, 2007 Intravenous Medications, 23rd edition, by Betty L. Gahart and Adrienne R. Nazareno). Therefore. . .a 500 mL solution with 30 units of Pitocin in it will contain 60 milliunits of the Pitocin.Client is admitted to labor and delivery for a trial induction. Begin Pitocin at 2 milliunits per minute and increase by 1 milliunit every 15 minutes until 3 good contractions every 10 minutes. Available: 500 mL of normal saline with 30 units of Pitocin. What rate (mL/hr) should be set on the infusion pump to begin the infusion?Dose desired: 2 milliunits (mU)/minute
Dose on hand: 30 units/500 mL, or 60 mU/500 mL
500 mL/60 mU (dose on hand) x 2 mU/minute (dose desired) = 16.666 mL/minute, rounded off to 17 mL/minuteLast edit by Daytonite on Jan 22, '08

1 Unit = 1000 milliunits (mU)
dose desired: 2 milliunits/min
dose on hand: 30 units/500 mL or 60 milliunits/mL (this is the dose concentration)
so: dose desired x dose concentration
2 milliunits/min x ml/60 milliunits = 0.033 mL/min
set on the infusion pump? 0.033 mL/min x 60 min/hr = 1.9 mL/hr or 2 mL/hr 
Aug 10, '09 by kgh31386, BSN, MSNYep, that's a good explanation. I did it just a tad bit differently, basically just cancel out the units. But I'm looking at daytonite's explanation, I was wondering if you could explain that, because we got totally different answers..unless I'm wrong, but I thought 1000mu were in 1u
2mu x 1u x __500ml x 60min = 2ml/hr
min `1000mu``30u ``1hrLast edit by kgh31386 on Aug 10, '09
