# milliunits

- 1Jan 22, '08 by ljbutlerCan 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......

*Daytonite*Quote 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,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?__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.**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/minute**Last edit by Daytonite on Jan 22, '08aarohi likes this. - 1Aug 6, '09 by etxyzQuote from ljbutlerjust glad to find this dosage problem in milliunits. here's my answer...Can anyone provide help with the following med math problem:

:spin:

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**kgh31386 likes this. - 0Aug 10, '09 by kgh31386Yep, 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
