Dehydration Flashcards
Dehydration define
Decrease the body water due to increased water loss and or decrease the intake
Lots of water and electrolytes, mainly sodium from extracellular fluid
Clicical picture of dehration
What is the test done to know that the skin lost its elasticity?
Pinching the skin will go back slow slowly more than two seconds
Most dangerous type of dehyration and why why
Hyper tonic
Intra cranial hgh
Rebound edema in ttt
The commonest type of dehydration
Iso tonic
Moist skin in dehdartion
Hypotonic
Normal serum na
130-150

Only symptom detected in mild dehydration
Weight loss from 3-5 %
Compare between degrees of deydartion
Sunken ant fontanella
Tenting
Why glucose used in ors
Fcailitate water and na absorbtion even during diarrhhea
Not as caloric source or for taste
Composition of ORS suchet
Composition of ORS dissolved in 1 L
How to use ORS when there is a risk of developing hypernatremia
Low sodium content 45/60 milliliters, equivalent per liter
Mention a moment used in the diarrhea was dehydration of ORS
Mention the amount used of ORS in diarrhea with no dehydration
Maximum range of serum sodium taking ORS
120-160
Mention indications of ORS
Methods of giving ORS give the usual method and the exception method
Timing of feeding it, and the method and the aim
Is antibiotics routine used for diarrhea
No bec
Metronidazole Flagyl is indicated if
Mention ttt plan
ORS
Feeding eraly gradual
Drugs ( ab only in bacillary , flagyl if parasite)
Symptomatic ttt(fever , vomiting , diarrhea)
Ttt of complication
Indications of iv in case of dehydration
Describe steps of crystalloid incase of dehydration
When u should add k and how much
Voids urine
20 mL equivalent per liter
Ampoule 10 cm
When not to give k to patient
When he doesn’t void urine
When using kadlex
Rate of NA decline is
10-12 meq/l per day
To rapid reduction in the plasma sodium will lead to
Shifting of water into cerebral cells will lead to cerebral edema and convulsions
How to treat a cerebral edema due to rapid deductions of plasma sodium
Boy using hypertonic saline 3%
What to do in severe resistant cases of severe hypernatremia with sodium intoxication
Peritoneal dialysis
Duration of IV fluids, according to concentration in hyper dehydration
Mention type of the fluids and the rate of sodium drip drop in hypernatremia dehydration
Add hyponatremic dehydration why correction of sodium must be slow
To avoid acute pontine demylnisosi
The type of the flute amount and the duration in hypothermic dehydration
