Profound disturbances of other electrolytes
hypoK
- may lead to nephrogenic DI if severe
- replace with IV if possible for its reliability
Hypophosphataemia
- hypoPO4 is a risk factor of ODS
- Proactively start thiamine (esp. in alcoholics)
- Replacing PO4 doesn’t per se affect [Na]. It is the coupling Na/K that counts
