Tumor Lysis Syndrome — ICU Decision Pathway

Prevention and ICU treatment of tumor lysis syndrome with electrolyte emergencies, urate control, AKI prevention and timely dialysis.

Assessment StepRecognize TLS before treatment startsExplore Topic
High tumor burden, rapidly proliferative or treatment-sensitive malignancy, high LDH, renal dysfunction and elevated baseline urate increase risk; spontaneous TLS can occur.
Clinical ActionMonitor potassium, phosphate, calcium, urate, creatinine and ECG closely
High-risk patients need frequent laboratory reassessment and cardiac monitoring because hyperkalemia and hypocalcemia-related arrhythmias may evolve rapidly.
Reassessment / LoopReassess response and escalate
Trend physiology and organ function; if the patient is worsening, revisit diagnosis, source control and rescue options rather than repeating ineffective therapy.

An educational representation of clinical reasoning, not a diagnostic algorithm or personalized medical advice — always apply clinical judgment and institutional protocols.

Caution

Escalate — Red Flags & Critical Warnings

  • Escalate early for shock, rapidly progressive organ failure, dangerous ECG/airway findings or failure of initial therapy.
