Renal traumas are caused by
traffic accidents, stabbing, gun shot wounds
Why are renal traumas uncommon?
the rib cage and surrounding heavy muscles offer protection
A contusion to the kidney can cause
Minor and Major lacerations can cause
When will you see Grey Turner's sign?
with renal trauma, especially minor and major lacerations
What is Grey Turner's sign?
bruising around the back and on flank, blood in the tissue
What is the patient susceptible to with lacerations?
What is the cardinal sign of renal trauma?
Hematuria, seen in 80% of cases
How are renal injuries usually treated (Except for a clot)?
Conservatively (not rushed to surgery)
What is Acute Renal Failure?
Abrupt loss of kidney function
What do Creatinine and BUN do in ARF?
What does GFR do in ARF?
Normal Urine output?
400/ml/24 hrs or more
100 - 400ml/24 hrs
less than 100 ml/24 hrs
Causes of ARF?
Prerenal, Intrarenal and Postrenal
Prerenal cause of ARF
hypovolemia, fluid shifts, gram negative sepsis, decreased C.O., Decreased peripheral vascular resistance, vascular obstruction
Anything that stops perfussion or is volume related is what kind of cause of ARF?
If fluid is in the tissue rather than in the vascular space and there is decreased peripheral vascular resistance what is needed?
A fluid bolus
What is the most common cause of ARF?
Intrarenal or Acute tubular necrosis
Acute tubular necrosis?
most common cause of intrinsic renal failure. abrupt damage b/c of decrease blood flow associated with shock. characterized by destruction of tubular epithelial cells
Intrarenal cause of ARF
Acute tubular necrosis, damage from nephrotoxins, rhabdomyolysis, surgery, crush injuries, electric shock, use of statin drugs, seen in patients "found down"
Treatment for acute tubular necrosis?
bed rest, correct electrolytes, fluid volume and dialysis
Post renal cause of ARF?
Prostate disease, obstruction (stones), pelvic trauma, surgical accidents, spinal cord injury
Phases of acute renal failure
Onset, Oliguric-anuric, diuretic and recovery
A condition in which damaged skeletal muscle tissue breaks down rapidly. Breakdown products of damaged muscle cells are released into the bloodstream; some of these, such as the protein myoglobin, are harmful to the kidneys and may lead to kidney failure
Onset phase of acute renal failure
starts with the precipitating event and continues to the development of renal symptoms (labwork)
Oliguric - Anuric phase of acute renal failure
lasts 1-8 weeks, the longer this phase lasts the poorer the prognosis
Diuretic phase of acute renal failure
starts when BUN and Creat get back to normal
What is most important in the diuretic phase of acute renal failure?
Hydration! Patients can die in the this phase if they aren't hydrated
Recovery phase of acute renal failure
3-12 months long, mild abnormalities, decreased concentration of urine
What is patient at risk of for the rest of their life in the recovery phase of acute renal failure?
Fluid and Electrolyte imbalances
What is a significant cause of death for patients with ARF?
How to prevent infection for pts with ARF?
strict sterile technique, avoidance of indwelling cath's
Medical management of ARF
Prevention, hydration, adequate diuresis, watch labwork, I&O, weights, maintain fluid and electrolyte balance, replace renal function (dialysis), prevent infection
Complications associated with ARF
Pericarditis (fluid backs up), Tachy, fever, friction rub, seizures (due to increased BUN), anemia (due to bleeding from trauma)
Nursing management for ARF
fluid volume deficit or excess, imbalanced nutrition, impaired skin integrity, risk for infection, anxiety
What kind of diet do you want for ARF?
High calorie, low protein
Older clients are at risk for ARF due to decreased what?
Chronic Renal failure
Progressive and irreversible reduction of functional renal tissue
Stage 5 of chronic renal failure is called what?
End stage renal disease
When kidneys can no longer maintain the body's internal environment
If ARF event happens and a pt does not recover what can happen?
#1 cause of CRF?
Diabetes (more than 30% of dialysis patients are diabetic
