• Low serum albumin from severe infection/inflammation, poor nutrition, protein loss, or liver dysfunction
• Kidney disease, especially nephrotic syndrome, which classically causes proteinuria, low albumin, and generalized edema
• Less commonly heart failure, fluid overload, or sepsis-related capillary leak

• Vitals, oxygen saturation, perfusion, mental status, weight, fluid balance, and urine output
• CBC with differential, CRP/procalcitonin, blood culture before antibiotics if feasible
• Liver enzymes, bilirubin, PT/INR, albumin, renal function, electrolytes, glucose
• Urinalysis and urine protein/creatinine ratio to look for nephrotic-range protein loss
• Ultrasound review, often contrast CT/MRI if extent, loculations, rupture, or drainage planning is unclear
• Culture of aspirated pus if aspiration/drainage is performed
• Assessment for nutritional status and predisposing conditions, including immune dysfunction if infection is unusual/recurrent. Children with immunodeficiency, including chronic granulomatous disease, are at increased risk of hepatic abscesses.

• Prompt IV broad-spectrum antibiotics, chosen locally and then narrowed to culture results. Coverage commonly needs enteric gram-negative bacteria, streptococci, anaerobes, and, in young children or depending on local epidemiology, Staphylococcus aureus.
• Ultrasound-guided aspiration or catheter drainage if clinically indicated.
• Careful fluid and edema management. Do not give diuretics, albumin, or large fluid volumes without a pediatric clinician assessing circulation, kidney function, albumin, and urine output.
• Serial clinical exam, inflammatory markers, and ultrasound to ensure the collections are resolving.

Main concerns to evaluate now

1. Hypoalbuminemia
   • Severe infection can lower albumin through inflammation, capillary leak, reduced intake, and dilution from IV fluids.
   • Liver dysfunction or malnutrition may contribute.
   • Check serum albumin, total protein, LFTs, bilirubin, PT/INR, and review daily fluid intake/output and weight.
2. Renal protein loss or acute kidney injury
   • Nephrotic syndrome is a key alternative cause of generalized edema in children: edema + heavy proteinuria + low albumin.
   • Obtain urinalysis for protein/blood, spot urine protein:creatinine ratio, creatinine, urea, electrolytes, and strict urine-output monitoring. Nephrotic-range proteinuria, hypoalbuminemia, and edema are the defining combination.
3. Sepsis-related capillary leak / fluid overload
   • Even while fever is improving, fluid accumulated during the acute illness can cause edema.
   • Assess perfusion, blood pressure, respiratory rate, oxygen saturation, hepatomegaly, lung crepitations, ascites, and chest X-ray/bedside lung ultrasound if respiratory signs or concern for pulmonary edema.
   • Any fluid, albumin, or diuretic decision must be based on whether she is intravascularly depleted versus overloaded. Giving diuretics without this assessment can be harmful.
4. Hb 7.3 g/dL
   • This is significant anemia and needs an explanation: baseline nutritional/iron deficiency, inflammation, hemolysis, blood loss, dilution, malaria depending on geography, etc.
   • Request/review MCV/MCH/RDW, reticulocyte count, peripheral smear, bilirubin/LDH if hemolysis is suspected, stool/other bleeding history, and iron studies when clinically appropriate.
   • In a hemodynamically stable critically ill child, evidence-based pediatric guidance generally advises not routinely transfusing when Hb is at least 7 g/dL. At 7.3, transfusion is not automatic, but the team should make an individualized decision based on tachycardia not explained by fever, shock, hypoxia/respiratory distress, active bleeding, cardiac disease, falling Hb, or ongoing severe sepsis. The TAXI pediatric transfusion recommendation supports this restrictive threshold in stable children.

Regarding the abscess

• blood cultures were obtained and reviewed
• pediatric surgery/interventional radiology has assessed whether aspiration is feasible and useful for culture/source control
• repeat ultrasound is planned if fever, CRP/TLC, pain, or clinical status does not continue to improve

Escalate urgently / PICU review if any of these occur

• reduced urine output, hypotension, cold extremities, prolonged capillary refill
• increasing work of breathing, falling oxygen saturation, lung crackles
• increasing abdominal distension, severe pain, vomiting, jaundice
• altered alertness, persistent high fever, or worsening inflammatory markers
• rapidly increasing edema or Hb falling further

• Serum albumin and total protein: may not be included in every LFT panel, so confirm.
• Electrolytes, especially sodium and potassium.
• Urine routine/microscopy and urine protein. If protein is positive, obtain a spot urine protein:creatinine ratio.
• Strict urine-output charting, daily weight, blood pressure, and fluid input-output balance.
• PT/INR if there is concern for impaired liver synthetic function.
• CBC indices, peripheral smear, and reticulocyte count if the cause of Hb 7.3 is unclear.

• low albumin/capillary leak from severe infection or fluid administration
• renal protein loss, such as nephrotic syndrome
• kidney injury or salt/water retention
• liver synthetic dysfunction
• fluid overload

1. Anemia: Hb 7.3 g/dL

Immediate steps

• Repeat CBC and compare Hb trend.
• Check CBC indices: MCV, MCH, RDW, platelet count, WBC trend.
• If available: peripheral smear and reticulocyte count.
• Look for causes:
  • iron deficiency or malnutrition
  • anemia of acute inflammation/sepsis
  • hemodilution from IV fluids
  • hemolysis, if jaundice/dark urine or abnormal smear
  • bleeding, if any clinical suggestion

Blood transfusion

• shock, poor perfusion, persistent tachycardia out of proportion to fever
• breathlessness/hypoxia, heart failure, or significant respiratory distress
• active bleeding
• rapidly falling Hb
• major heart disease or another condition with high oxygen demand
• a planned urgent invasive procedure where the team considers a higher Hb necessary

2. Anasarca

Establish the cause first

• serum albumin and total protein
• bilirubin, AST/ALT
• PT/INR if albumin is low or liver dysfunction is suspected

• urine routine/microscopy
• urine dipstick for protein and blood
• spot urine protein:creatinine ratio if protein is present
• serum electrolytes, especially sodium and potassium
• blood pressure, daily weight, strict fluid chart, and hourly or regular urine output

Management after assessment

• Review IV fluids daily: stop unnecessary maintenance fluids, dilute infusions, and excess sodium, while maintaining adequate hydration/perfusion.
• Daily weight and strict input-output monitoring: these are more reliable than visual assessment of edema alone.
• Nutrition review: adequate calories and protein are important, within the limits set by renal and liver status.
• Salt restriction is commonly used for significant edema, but exact fluid and sodium plans should be prescribed by the inpatient team.
• If fluid overloaded but circulation and renal function are adequate, the clinicians may consider a carefully monitored diuretic.
• If albumin is very low with severe symptomatic edema, some children receive albumin followed by a diuretic, but this is not routine and can be risky if there is pulmonary edema, renal impairment, or intravascular overload. It requires monitored hospital administration.
• If urine protein is high, request pediatric nephrology review. Generalized edema, hypertension, oliguria, and significant proteinuria merit urgent renal assessment.

3. Practical discussion for tomorrow’s round

1. “What is her albumin, urine protein result, creatinine, sodium, and daily fluid balance?”
2. “Is this likely capillary leak/fluid overload, kidney protein loss, or liver-related low albumin?”
3. “Does she need a pediatric nephrology review?”
4. “Is Hb stable or falling, and are the indices/smear consistent with iron deficiency, inflammation, dilution, or hemolysis?”
5. “Given her clinical stability and Hb 7.3, do you advise observation versus transfusion, and why?”
6. “What is the current plan for repeat ultrasound and whether aspiration/culture of the bilobar abscess is needed?”
