Management of Empyema Thoracis in Children

Initial Management Approach

• The American Thoracic Society recommends starting broad-spectrum intravenous antibiotics immediately, targeting common pathogens, and adjusting based on culture results, in children with empyema thoracis 1
• The use of small-bore chest drains, rather than large-bore drains, is recommended to minimize patient discomfort, as there is no evidence that large-bore drains provide any advantage 1
• Ultrasound guidance should be used to determine the optimal site for drain insertion in children with empyema thoracis 2
• The chest drain should be connected to a unidirectional flow drainage system, kept below the patient's chest level at all times, to prevent re-expansion pulmonary edema 1
• The drain should be clamped for 1 hour once 10 ml/kg are initially removed, to prevent re-expansion pulmonary edema, and never clamped if bubbling 1

Intrapleural Fibrinolytic Therapy

• Intrapleural urokinase should be administered for any complicated parapneumonic effusion or empyema, as this shortens hospital stay, with a dosing protocol of 40,000 units in 40 ml 0.9% saline for children ≥10 kg, and 10,000 units in 10 ml 0.9% saline for children <10 kg, administered twice daily for 3 days 1

Surgical Intervention

• Early discussion with a thoracic surgeon should be initiated if the patient fails to respond to chest tube drainage, antibiotics, and fibrinolytics, with specific surgical indications including persisting sepsis, organized empyema, and multiloculated empyema 1
• Formal thoracotomy and decortication is reserved for organized empyema with thick pleural peel, while video-assisted thoracoscopic surgery (VATS) can be effective for early intervention 1

Supportive Care and Monitoring

• Antipyretics should be provided for fever control, and adequate analgesia should be ensured to keep the child comfortable, particularly with a chest drain in place 1
• Chest physiotherapy should not be performed, as it is not beneficial in children with empyema, and early mobilization and exercise should be encouraged 1
• Secondary thrombocytosis and scoliosis are common but benign, and do not require specific treatment, but should be confirmed to resolve 1

Follow-Up

• Children should be followed after discharge until complete recovery and chest radiograph returns to near normal, with consideration of underlying diagnoses such as immunodeficiency or cystic fibrosis in appropriate cases 1

Empyema Thoracis Management

Initial Medical Management

• The American Thoracic Society recommends initiating early discussion with a thoracic surgeon if the patient fails to respond to chest tube drainage, antibiotics, and fibrinolytics within 48-72 hours 3, 4

Surgical Management Algorithm

• Surgery should be considered for persisting sepsis with persistent pleural collection despite antibiotics, chest tube drainage, and fibrinolytics 5
• The British Thoracic Society suggests that bronchopleural fistula with pyopneumothorax is an indication for surgery 3
• Complex empyema with significant lung pathology is an indication for surgery, according to the European Respiratory Society 4

Surgical Approach Selection

• Video-Assisted Thoracoscopic Surgery (VATS) is most appropriate for early surgery in the fibrinopurulent stage, offering less postoperative pain, shorter hospital stay, and better cosmetic results 3, 4, 5
• Open Thoracotomy and Decortication is reserved for late presenting empyema, chronic empyema, and organized empyema with thick fibrous peel causing chronic sepsis and restricted lung expansion 3, 4, 5

Critical Pitfalls to Avoid

• A persistent radiological abnormality in a symptom-free, clinically well patient is not an indication for surgery, as stated by the American College of Chest Physicians 3, 4, 5

Management of Gross Empyema in Children

Initial Medical Management

• Begin broad‑spectrum intravenous antibiotics that cover Streptococcus pneumoniae, Staphylococcus aureus, group A Streptococcus and anaerobes immediately, without awaiting culture results, in children with gross empyema. 6
• Insert a small‑bore chest drain (8–14 Fr) under ultrasound guidance to minimize discomfort and improve drainage success. 6
• After an initial drainage of ≈ 10 ml kg⁻¹, clamp the chest drain for 1 hour to reduce the risk of re‑expansion pulmonary edema. 6
• Check drain patency daily and flush the system if drainage suddenly stops. 6

Intrapleural Fibrinolytic Therapy

• Administer intrapleural urokinase for any gross empyema or complicated parapneumonic effusion with loculations; this shortens hospital stay and improves drainage. 6
• Dosing:
  
  • Children ≥ 10 kg – 40,000 U urokinase diluted in 40 ml 0.9 % saline.
  • Children < 10 kg – 10,000 U urokinase diluted in 10 ml 0.9 % saline.
  • Give twice daily for 3 days (total 6 doses). 6

Surgical Intervention

• Refer urgently for video‑assisted thoracoscopic surgery (VATS) if the child remains febrile with a persistent pleural collection after 7 days of chest‑tube drainage, antibiotics, and fibrinolytics. [6][7]
• Indications for surgical referral include:
  
  • Persistent sepsis with ongoing pleural collection despite optimal medical therapy. 6
  • Complex empyema with a thick fibrous peel and trapped lung (delayed presentation). 7
• VATS is the preferred approach for early‑stage empyema, providing less postoperative pain, shorter hospitalization (≈ 7.4 days vs 15.4 days with open thoracotomy), and better cosmetic outcomes. 7
• VATS is most effective when performed during the fibrinopurulent stage; failure rates rise in advanced organized empyema. 7
• Formal thoracotomy with decortication should be reserved for late‑presenting, chronic, or organized empyema with a dense fibrous rind causing a trapped lung. 7
• Contraindications to VATS include inability to create a pleural window, presence of thick purulent material, or a dense fibrotic pleural rind. 7
• A persistent radiological abnormality in an asymptomatic, clinically well child does not constitute an indication for surgery. 7

Supportive Care

• Provide antipyretics for fever control. 6
• Ensure adequate analgesia, especially while a chest drain remains in situ. 6
• Do not perform routine chest physiotherapy, as it offers no benefit in pediatric empyema. 6
• Encourage early mobilization and gentle exercise to aid recovery. 6

Monitoring and Follow‑Up

• Expect clinical improvement (fever resolution, better respiratory status, decreasing inflammatory markers) within 48–72 hours of initiating therapy.
• Monitor for secondary thrombocytosis (platelet count > 500 × 10⁹ L⁻¹) and transient scoliosis on chest radiograph; these are common, benign findings that require no specific treatment. 6
• Follow children after discharge until complete clinical recovery and a chest radiograph approaches normal. 6
• Consider evaluation for underlying conditions (e.g., immunodeficiency, cystic fibrosis) in cases with atypical or recurrent empyema. 6

Critical Pitfalls to Avoid

• Do not delay surgical referral beyond 7 days of failed medical management, as delays increase morbidity, prolong hospitalization, and worsen outcomes.
• Always use imaging guidance (ultrasound or CT) for chest‑tube placement; avoid blind insertion.
• Never omit anaerobic antimicrobial coverage, given the high prevalence of anaerobes in empyema.
