Definition & background
 Pathophysiology
 Causes
 Clinical approach
 investigations
 Management of edema



Accumulation of excess interstitial fluid and
could be localized or generalized.




Edema results from either excess salt &
water retention or from increased transfer
of fluid across the capillary membranes.




Understanding of the Pathophysiology of
edema is important in the clinical approach
and management of this condition in children.
Distribution:
1- Anasarca; gross, generalized edema with
profound subcutaneous tissue swelling.
2- Localized edema; does not reflect a sustained
impairment in the ability to maintain normal Na
balance.
3- Special forms of fluid collections in the
different body cavities
 Hydrothorax (in pleural cavity)
 Hydropericardium (in pericardial cavity)
 Ascites (in peritoneal cavity)





Generalized edema can arise via two
different processes;
Reduced intravascular volume leading to Na
& water retention → under-filling edema




Na & water retention secondary to expanded
plasma & intracellular tissue fluid volume
accompanied by lack of natriuresis → overfilling edema.







Mechanism of under-filling edema

Initiated with ↑↑ glomerular permeability to
albumin → albuminuria → hypoalbuminemia →
↓↓ plasma oncotic pressure → movement of
water from intravascular space to the
interstitium.
The contracted intravascular volume→↑↑
RAA activity +↑↑ SNS activity + ADH release
These factors→ water & Na retention→
further ↓↓ plasma oncotic pressure→ setting
up a vicious circle






Mechanism of over-filling edema
Resulting from expanded extracellular
volume that results from primary renal
Na retention, possibly secondary to
the renal damage.
In over-filling edema the RAA system
& SNS & ADH secretion are
depressed.









Causes of edema according to physiological
changes:
Increased hydrostatic pressure
Decreased plasma oncotic pressure
(hypoproteinemic states)
Increased capillary leakage
Impaired lymphatic flow
Impaired venous flow
1- Increased hydrostatic pressure
 Acute nephritis syndrome
 Acute tubular necrosis
 Cardiac failure-low output (CCF)
 Cardiac failure-high output
(hyperthyroidism, anemia, beriberi)
 Arteriovenous fistula
 Acute and chronic renal failure
 Constrictive Pericarditis & restrictive
cardiomyopathy
2- Decreased plasma oncotic
pressure (hypoproteinemic states)
 Nephrotic syndrome
 Chronic liver failure, autoimmune
hepatitis, fulminant hepatic failure
 Protein losing enteropathy
 Protein caloric malnutrition
 Severe burns
3- Increased capillary leakage
 Insect
bite, trauma, allergy, sepsis, &
angio-edema
 Vasculitis (anaphylactoid
purpura, SLE, dermatomyositis, pol
yarteritis nodosa, scleroderma, &
Kawasaki disease)
4- Impaired lymphatic flow
 Lymphatic obstruction (tumor), congenital
lymphedema.
 Milroy disease in newborn
 Wuchereria bancrofti infection
 Post-surgical & post irradiation
5- Impaired venous flow
 Hepatic venous outflow obstruction,
superior/inferior vena cava obstruction
6- Others
 Myxedema, Hydrops fetalis, drugs like
NSAIDs, steroids, vasodilators etc…






Confirm edema
Assess distribution of edema:
generalized VS localized edema
Detailed history and physical
examination to assess severity,
associated complications, and
underlying cause of edema.




Assess distribution of edema

generalized VS localized edema
In generalized edema look for
pretibial, sacral, scrotal, vulval
edema other than periorbital
edema and ascites.








Localized edema
Hx. Of trauma, insect bite, or
infection
Peripheral lymphedema in female
newborn  to exclude Turner’s
syndrome
Acute edema of the face and neck 
to exclude superior vena cava
obstruction syndrome.
B- Generalized edema
1- Renal disease (most common cause in children)
 Rapid onset edema, puffiness around the
eyes, gross hematuria, oliguria, hypertension,
cardiomegaly, pulmonary edema to suggest
acute glomerulonephritis.
 Frothy urine suggests nephrotic syndrome.
 Absence of circulatory congestion
differentiates nephrotic syndrome from
nephritic syndrome.






Signs and symptoms of chronic insufficiency
such as anemia, growth retardation, and uremic
symptoms such as nausea and vomiting.
Exclude secondary causes such as postinfectious glomerulonephritis (history of throat
or skin infection in recent past), SLE, Henoch
Schonlein purpura (skin rash & joint pain).
Look for symptoms of hypertensive
encephalopathy (headache, irritability,
confusion, altered sleep pattern, & convulsion).








Ask for hx of
fever, anorexia, vomiting, abdominal
pain, progressive jaundice, fetor
hepaticus, bleeding manifestations, clay
color stool, black tarry
stool, hematemesis, pruritis & abdominal
distension.
Stigmata of chronic liver disease such as
palmar erythema, clubbing & spider naviae.
HSM with gross ascites in the absence of
jaundice to exclude portal vein thrombosis.
Previous operation scar such as Kasai portoenterostomy.








Symptoms of CCF such as decreased effort
tolerance, orthopnea, paroxysmal nocturnal dyspnea
in older children and poor weight gain, feeding
difficulties, excessive sweating, bluish episodes and
respiratory distress in infants.
Signs of cardiomegaly, gallop rhythm, precordial
pulge, pallor, cool extremities, elevated JVP, weak
pulse, pulsus paradoxus, murmur, displaced apex
beat, tender hepatomegaly, & lung crepitations.
Assess for underlying cause such as structural heart
disease, cardiomyopathy & myocarditis.
Edema in cardiac disease often denotes a late sign in
small children.








Hx of chronic diarrhea, steatorrhea, foul
stools, FTT, repeated infections &
redcurrant abdominal pain.
Detailed dietary history for possible cow
milk allergy and gluten hypersensitivity
Assess for complications of anemia,
malnutrition and vitamin deficiency
This condition should be considered in every
case of unexplained edema (even without
diarrhea) especially when it is associated
with hypoproteinemia.




Hx of anorexia, lethargy, diarrhea, vomiting,
FTT, susceptibility to infections, night
blindness, inadequate or inappropriate
dietary hx especially prolonged lack of
protein.
In examination; growth parameters, pallor,
apathy, irritability, skin changes, hair
changes, & signs & symptoms of
micronutrient deficiency.






Edema usually mild, commonly periorbital.
Hx of allergen exposure such as medications,
animal dander, food preservatives and
coloring.
Associated rashes such as urticarial.
Assess for Steven-Johnson reaction.

Protein losing
enteropathy
A- Urine dipstick & microscopy
 Proteinuria, hematuria, & casts are
indicative of renal disease

B- RFT
 Raised serum urea & creatinine are
indicative of renal disease
C- Full blood count
 Normochromic Normocytic anemia
suggest chronic disease
 Hypochromic microcytic anemia
suggest IDA from occult GIT bleeding
e.g. cow’s milk allergy
 Megaloblastic anemia suggests B12 and
folate deficiency from small bowel
disease
D- LFT
 Hypoalbuminemia in the absence of
circulatory overload suggests
hypoproteinemic states
 Hyperbilirubinemia and elevated liver
enzymes suggests liver disease
E- Chest X-ray and ECG
 Cardiomegaly with prominent perihilar
vascular markings/upper lobe diversion
and left ventricular hypertrophy
confirms intravascular fluid overload







N.B if these basic investigations do not
reveal the cause of edema, further
investigations may have to be done:

- Echocardiography
- Serum-ascites albumin gradient
(SAAG)
- CT scan or MRI abdomen
SAAG > 1.1 gm/dl
Liver cirrhosis
Veno-oclusive dis.
Fulminant hepatic failure
Cardiac ascites
Mixed ascites
Liver metastasis

SAAG < 1.1gm/dl
Nephrotic syndrome
TB
Nutritional
Collagen vascular dis.

High SAAG, normal protein Budd chiari synd. & constrictive pericarditis

High SAAG, low protein liver cirrhosis
Low SAAG, low protein nephrotic syndrome, TB, nutritional
Low SAAG, normal protein chylus ascites, pancreatic ascites
* General measures

1- Dietary management
Na restriction to 2gm/m2/day
 Fluid restriction to 2/3 of maintenance
depending on the severity of edema
2- Diuretics therapy
3- Bed rest
4- Specific therapy according to the cause









Edema more in the morning and subsiding by
evening is suggestive of renal edema
Ascites to start with, followed by edema may
suggest a possibility of hepatic failure
Nutritional history combined with
anthropometry, vitamin & mineral deficiency
signs, points to the diagnosis of nutrition
deficiency states like kwashiorkor
Edema in the dependant part associated with
tachypnea and abnormal findings in the heart
suggests the diagnosis of cardiovascular
diseases.

        Hx of chronicdiarrhea, steatorrhea, foul stools, FTT, repeated infections & redcurrant abdominal pain. Detailed dietary history for possible cow milk allergy and gluten hypersensitivity Assess for complications of anemia, malnutrition and vitamin deficiency This condition should be considered in every case of unexplained edema (even without diarrhea) especially when it is associated with hypoproteinemia.
  • 56.
      Hx of anorexia,lethargy, diarrhea, vomiting, FTT, susceptibility to infections, night blindness, inadequate or inappropriate dietary hx especially prolonged lack of protein. In examination; growth parameters, pallor, apathy, irritability, skin changes, hair changes, & signs & symptoms of micronutrient deficiency.
  • 57.
        Edema usually mild,commonly periorbital. Hx of allergen exposure such as medications, animal dander, food preservatives and coloring. Associated rashes such as urticarial. Assess for Steven-Johnson reaction.

    A- Urine dipstick& microscopy  Proteinuria, hematuria, & casts are indicative of renal disease B- RFT  Raised serum urea & creatinine are indicative of renal disease
  • 60.
    C- Full bloodcount  Normochromic Normocytic anemia suggest chronic disease  Hypochromic microcytic anemia suggest IDA from occult GIT bleeding e.g. cow’s milk allergy  Megaloblastic anemia suggests B12 and folate deficiency from small bowel disease
  • 61.
    D- LFT  Hypoalbuminemiain the absence of circulatory overload suggests hypoproteinemic states  Hyperbilirubinemia and elevated liver enzymes suggests liver disease
  • 62.
    E- Chest X-rayand ECG  Cardiomegaly with prominent perihilar vascular markings/upper lobe diversion and left ventricular hypertrophy confirms intravascular fluid overload
  • 63.
        N.B if thesebasic investigations do not reveal the cause of edema, further investigations may have to be done: - Echocardiography - Serum-ascites albumin gradient (SAAG) - CT scan or MRI abdomen
  • 64.
    SAAG > 1.1gm/dl Liver cirrhosis Veno-oclusive dis. Fulminant hepatic failure Cardiac ascites Mixed ascites Liver metastasis SAAG < 1.1gm/dl Nephrotic syndrome TB Nutritional Collagen vascular dis. High SAAG, normal protein Budd chiari synd. & constrictive pericarditis High SAAG, low protein liver cirrhosis Low SAAG, low protein nephrotic syndrome, TB, nutritional Low SAAG, normal protein chylus ascites, pancreatic ascites

    * General measures 1-Dietary management Na restriction to 2gm/m2/day  Fluid restriction to 2/3 of maintenance depending on the severity of edema 2- Diuretics therapy 3- Bed rest 4- Specific therapy according to the cause 
  • 66.
        Edema more inthe morning and subsiding by evening is suggestive of renal edema Ascites to start with, followed by edema may suggest a possibility of hepatic failure Nutritional history combined with anthropometry, vitamin & mineral deficiency signs, points to the diagnosis of nutrition deficiency states like kwashiorkor Edema in the dependant part associated with tachypnea and abnormal findings in the heart suggests the diagnosis of cardiovascular diseases.
