Total Body Water Calculator
Estimate total body water based on patient characteristics to guide fluid and drug dosing.
Simple Molecule Size Searcher
This is just to find out what molecules are the right size for what sort of extracorporeal removal, if at all. These weights are (mostly) just an approximation, especially as they get into the tens of thousands. Have a go. I found it interesting, hopefully you might, too. NB: Haemodialysis generally removes molecules <20kDa in … Read more
Enterocutaneous fistula
The approach is graphically summarised here. It’s based on Alex Yartsev‘s awe-inspiring Deranged Physiology post, as well as Cohen et al (2016), Lundy & Fischer (2010) and Evenson (2016). The final decision-loop ignores the third possibility, which is that the patient is stable enough to go on living with a chronically-discharging ECF. I had to draw the line … Read more
Simple Trial Searcher
Select the intervention / condition / study from the drop downs and hit search. alternatively just start typing in the ‘search’ box and it’ll udpate live. If you want all ACS-related stuff, type ACS into the search bar. If you want just the ACS stuff related to NSTEMI, consider the dropdown instead. Search ICU Trials … Read more
