To be sure, the Murphy drip was used extensively in WW1. Kinda makes you wonder what those fucking WW2 coconut iv guys were doing when you had perfectly fine access from the bottom that could take boiled water full of pyrogens just fine. And if you’re in enough of a volume depleted state where a Murphy drip can’t help due to vasoconstriction then all that potassium from a volume infusion of coconut ivs is gonna kill ya anyway.
