    This may sound like a stupid question, but I start my audition AI next week and it's been a year since Jr. Peds clerkship. I've tried to look it up, but can't find it: What is formula for calculating fluid requirements? I know it's something like 4ml/hr for the first 10k and 2 for the next . . . or something like that. I just know that housestaff knows it like the back of their hand

    So I came here for help.

    You are pretty much there - 4ml/kg/hour for the first 10k, 2ml/kg/hour for the 10-20k, then 1ml for each additional kg after that..


    5kg kid = 20ml/hr
    10kg kid = 40ml/hour
    15kg kid = 40ml/hour + 10ml/hour = 50ml/hour
    25 kg kid = 40 ml/hour + 20ml/hour+ 5ml/hour = 65ml/hour

    Easy to remember that anything over 20kg = 60ml/hour plus 1ml per kg.

    This equation works in most cases - but will not work for renal kids etc. Good luck on your rotation.

    Also, I would recommend buying a copy of the Harriet Lane Handbook for your rotation - get to know it now and it will really come in handy during your intern year.
