So its a while since we highlighted any great PEM learning sites and I stumbled across pemplaybook.org when this episode appeared on ERcast.
They put forward an intuitive structure to the assessment of the sick infant that appeals to me more than the usual ABCD. If you like mnemonics you're gonna love it..... Check the webpage for the notes - very helpful.
The only caveat is that I don't think I would rush to do ABGs to pick up congenital heart disease. I was trained to start with 4 limb BP and sats..... (while frantically calling for help) but I'd be interested to hear any other approaches.
