How often do you prescribe or give i.v. fluids to your patients? How much thought goes into what's contained in that fluid? What effect will you fluid choice have on your patient?

Two trials on crystalloid administration in the acutely unwell patient have occupied a lot of conversation in the research world over the last few weeks, both published in the NEJM and in this podcast we take a look at them.

In the podcast we cover the following;

• Whats the big deal with crystalloids
• Previous trials on fluid administration
• NEJM papers on crystalloids
• Myburgh's editorial

Make sure you take a look at the papers yourself and come up with your own conclusions. There are a whole host of superb FOAM resources out there on the topic that are well worth a look and referenced below.

We'd love to hear any thoughts and comments below.

Enjoy!
