Different signs of Hypovolemia
5%, 10%, 15%
Mucus
LOC
Orthostatic [HR, BP]
UOP
PULSE RATE
Laboratory/ Monitoring evaluation for Hypervolemia
Where do you start your Fluid challenge?
you can always give more, never less
What are the most common electolyte that you will be giving?
Sodium
Potassium
Calcium
Magnesium
Percent of Intracellular and Extracellular
Fluid in the body
Intracellular is so much bigger than extracellular fluid
What electrolyte does NS have?
Na 154
Cl 154
Ph 4.2
mOsm/L: 308
What is the composition of LR
Na: 130
Cl: 110
K: 4
Ca: 3
What is the composition of Plyte?
Na: 140
Cl: 98
K: 5
Mg: 3
ph: 7.4
mOsm/L: 294
What is the goal of Hyponatremia?
What is causing the electrolyte disturbance?
- Na and water deficit
- Water excess
- Na and water excess
What is the level of Hyponatremia you should be worried about and you may see seizure
<110
What is the tx of hyponatremia
can you rapidly correct hyponatremia?
What is safe for GA?
NO!
may cause central pontine myelinolysis
>130
What is the goal for correction of Hyponatremia?
6-8 meq / l
*key is slow correction and checking your sodium levels
What is an EKG change that you can see for hypokalemia
U waves, T wave flattening, ST- segment changes
What are the TX of hypokalemia
Remember that NDMB should be reduced 25-50% since hypokalemia causes increased sensitivity.
What are Hyperkalamia EKG changes?
numbness tingling on extremities
What is the presentation of Hypercalcemia?
Hypocalcemia EKG changes
prolonged Qt
What is the TX OF HYPOCALCEMIA?
what other electrolyte you should follow?
– follow Mg
EKG changes for hypocalcemia and hypercalcemia
Hypercalcemia Causes
Tx of Hypomagnesemia
