lyte levels for different fluids
144 - halfNS
>154 - should use the formula to make sure no cerbral edema
risks for SIADH
causes hyperconcentrated urine and hyponatremia
- meds
- post-op
- pain
- N/V
cons. of acute hyponat
fall to below 130 in 48 hours can cause acute cerbral edema and brain stem herniation
maintenance fluid formula
4-2-1 per 10Kgs
4 main types of fluid losses
- pure water - insensible
- sweat, respiration - hypotonic
- sweat, vomit, diarrhea - isotonic loss
- burns, diarrhea, urine of on thiazide - blood
8 Phx to assess dehydration
- HR
- systolic BP
- Urine output
- mucous membrane
- ant. fontanelle
- eyes
- skin turgor
- thrist
- LOC
see P 112 for exact numbers
3 main principles for rehydration
- rehydration - replace deficits in fluid and lytes that are down - NS
- replace ongoing losses 1:1
- provide maintenance 4-2-1 with D5W
rate for mild, mod and severe dehydrationg
mild (5%) - 50ml/kg ORT over 4 hrs
mod (5-10) - 100 ml/kg ORT over 4 hours
severe (>10%) 20ml/kg IV
prin. of ORT
for mild and mod only
- use lytes

what to use for IV boluses
