Definition
TBW x 140/current sodium
Then take this number and subtract from TBW
This is the amount fluid to be removed to correct Na to 140 or desired Na |

Term
| Sodium Deficit and correction |
|
Definition
(140-measured Na) x TBW
No more than 1/2 of this in 12-18 hr
Remaining replacement over 24-48 hr
Divide Na deficit by meq/liter of IVF you are using to replace (i.e. 154, 513) |
