Acute and chronic renal failure are two distinct conditions that with different pathophysiologies.
00:10
So let's compare the pathophysiology of acute renal failure and chronic renal failure.
00:18
So first the acute renal failure abbreviated as arf.
00:25
The first that is onset of the arf.
00:30
The onset of this is rapid.
00:34
This has a sudden and abrupt onset often occurring over a few hours to days.
00:43
Few hours to days.
00:45
Then second etiology.
00:49
It has reversible causes.
00:55
Causes reversible causes so typically arf is often caused by reversible factors such as dehydration then severe infections severe infections then drug toxicity it can be a drug toxicity or obstruction, drug toxicity or obstruction.
01:23
Then renal damage in arf is functional impairment, functional impairment.
01:33
So, the renal damage is primarily, primarily primarily functional, affecting the ability of the kidneys to filter and excrete waste products effectively.
01:47
It has functional impairment.
01:51
Then gfr in arf, it has gfr, rapid declining gfr.
02:00
So, gfr declines rapidly leading to a sharp decrease in renal function due to degrees in renal function due to rapid decline in gfr.
02:14
Then the clinical manifestation clinical manifestations of the arf include abrupt onset symptoms abrupt onset symptoms symptoms, so symptoms it may include oligo -oliguria means reduced urine output, oliguria or fluid and electrolyte imbalance, fluid and electrolyte imbalance.
02:50
Balance, then edema, edema or a rise in blood urea nitrogen that is bun and rise in serum creatinine level, serum creatinine level.
03:08
So, these are the clinical manifestations.
03:11
Now, the prognosis of arf prognosis is potentially, it is potentially reversible, potentially reversible.
03:26
So, arf can be reversible if the underlying causes can be, if the underlying causes is identified and then treated promptly...
