Lots of people (including myself) are curious about whether the evidence in the 5th edition of the RANZCOG Intrapartum Fetal Surveillance Guideline stacks up. So they ask - 

Show me the evidence!

The latest edition of the guideline is (at last!) quite transparent about where the evidence comes from and how they used it to decide which conditions make it onto the list of "risk factors for intrapartum fetal compromise" and which ones don't. This video looks at whether having a BMI of over 40 should be placed where it is on the risk factor list. I step you through how I go about answering a question like this - so you can develop the skills to do the same thing for any of the risks listed in the guideline yourself.
