RESUMEN
Introduction: Management of pediatric cancer patients involves invasive procedures such as punctures, injections, catheter placements, and chemotherapy which can generate fatigue, nausea, vomiting, anxiety, and pain. Virtual Reality (VR) is a nonpharmacological intervention classified as a cognitive-behavioral method to relieve symptoms. Methods: We designed a crossover protocol and included 20 patients between 9 and 12 years old; ten were male. All patients had acute lymphoblastic leukemia diagnosis and were treatedwith St. Jude's XV protocol in the maintenance phase. Pain and anxiety were measured with validated scales in the pediatric population. Results: Although we used a small group of patients, we found statistical difference in the reduction of anxiety and perception of time. Discussion: These results open a window to non-pharmacological treatments and show a strategy to improve quality of life in children inside the hospital.
