Management of BCG Sepsis with Fever, Difficulty Breathing, and Hypotension

Patients experiencing fever, difficulty breathing, and hypotension after BCG administration should immediately receive broad-spectrum antibiotics, anti-tuberculosis drugs, and be transferred to the ICU for intensive supportive care. 1

Immediate Management

  • Immediately stop BCG treatment when sepsis occurs 1
  • Transfer the patient to the ICU for intensive monitoring and supportive care 1
  • Collect blood and urine cultures for bacteria and acid-fast bacilli before starting antimicrobial therapy 1
  • Initiate fluid resuscitation with volume substitution under hemodynamic monitoring (central venous pressure, blood pressure, heart rate, cardiac output) 1

Pharmacological Management

  • Administer broad-spectrum antibiotics immediately 1
  • Start anti-tuberculosis drugs (isoniazid and rifampicin) 1
  • Add corticosteroids to reduce inflammatory response 1
  • For severe cases without renal failure, consider oral cycloserine with careful monitoring of blood concentration 1
  • If mean arterial pressure remains <65 mmHg despite adequate fluid resuscitation, initiate norepinephrine (0.1-1.3 μg/kg/min) 1
  • For sepsis-related myocardial depression with low cardiac output despite adequate volume, add dobutamine 1

Respiratory Support

  • For moderate to severe respiratory insufficiency, provide appropriate ventilatory support 1
  • In awake, cooperative patients with minor gas exchange disturbance (PaO₂/FiO₂ > 200), consider intermittent continuous positive airway pressure (CPAP) 1
  • For patients without hypotension or altered mental status, non-invasive positive pressure ventilation is preferred 1
  • Early initiation of non-invasive ventilation before development of severe hypoxemia is recommended 1
  • If respiratory status deteriorates or fails to improve, proceed to endotracheal intubation and controlled mechanical ventilation 1

Monitoring and Follow-up

  • Monitor vital signs, including temperature, blood pressure, heart rate, and respiratory rate continuously 1
  • Assess urine output and renal function regularly 1
  • Monitor for signs of progressive organ dysfunction 1
  • Follow lactate levels to assess tissue perfusion 1
  • Continue antimicrobial therapy until clinical improvement is evident 1

Prevention and Risk Factors

  • Strictly follow contraindications to BCG instillations 1
  • BCG treatment should be started at least 2 weeks after TURBT (transurethral resection of bladder tumor) to reduce risk of sepsis 1
  • Patients with immunodeficiencies should not receive BCG 1
  • Avoid BCG in patients with active infections or fever 1

Long-term Considerations

  • BCG instillation is no longer recommended after the patient recovers from BCG sepsis 1
  • Consider alternative treatment options for the underlying condition 1
  • Monitor for delayed complications of BCG sepsis, including granulomatous hepatitis or pneumonitis 1

Special Considerations

  • For patients with a history of BCG sepsis, live bacterial vaccines should be avoided in the future 1
  • Patients with innate immune defects should seek specialist advice regarding future use of live vaccines 1
  • Patients with phagocytic cell defects should not receive live bacterial vaccines such as BCG 1

This management approach prioritizes rapid intervention to address the life-threatening systemic inflammatory response while providing appropriate supportive care for organ systems affected by BCG sepsis.
