This has been posted before but I wanted to check again - does anyone have a best practice for KVO / carrier fluids for low volume infusions? (e.g. concentrated furosemide, PCAs, insulin, heparin, etc.)

The system I work for doesn't have a great process for nurses to recognize when a patient may need a carrier fluid or ordering and administering the fluid. Some of the additional questions are:

Hi I am looking for any information about your hospital's policy for KVO. I have searched and found no specific data and very few articles. Some data I have seen has rates as high as 50 ml/hr, while most of the list serves say it must be MD order specific.
