Did you know that the treatments used to cure pediatric cancers can potentially cause a life-threatening event known as tumor lysis syndrome (TLS)? Arfa Ul-Haque and Yazmin Reategui, two third-year medical students, are joined by Pediatric intensivist, Dr. Smitha Mathew, to discuss the evaluation and management for TLS so that it is promptly recognized and treated in the inpatient hospital setting. Specifically, they will: Review the basic assessment skills and evaluation for a child presenting with potential TLS Discuss the influence of chemotherapy, initial presentation, diagnostic options, and management of electrolyte imbalances found in TLS Medications reviewed: daunorubicin, cytarabine, calcium gluconate, Rasburicase, allopurinol Anticipatory guidance to medical professionals for potential onset of TLS Special thanks to Dr. Eric Ring and Dr. Rebecca Yang for peer reviewing this episode.
