Most of the water is in the intracellular space. Approximately 2/3 or 67% of TBW is found inside cells. That leaves one-third or 33% in the extracellular space. Most of the extracellular fluid, 3/4 or 75%, is in the interstitial space. The last 1/4 or 25% is in the IV space. If fractions work better […]
Back to Basics: Water distribution
Water can be found inside or outside cells – The intracellular or extracellular space. The extracellular space is divided into the interstitial space and intravascular (IV) space. The interstitial space is the fluid surrounding cells and outside the vasculature. The IV space aka plasma volume is the fluid inside blood vessels. Plasma volume is not […]
Back to Basics: TBW
Ever feel like the more you learn, the less you know? That’s often how I feel about fluid therapy, so let’s get back to basics. Total Body Water (TBW) In dogs and cats, TBW is approximately 60% of their weight. Remember that 1 liter of water weighs 1 kilogram. For a 25 kg dog, TBW […]

A somewhat elementary mnemonic for emergent dialysis.
Getting Proactive with Transfusion Reactions
Transfusions save lives but come with some risks. Below are some decision trees (inspired by the AVHTM TRACS consensus statement) that help walkthrough common transfusion reactions. Click the image to enlarge.
