Background: In the pediatric population, symptoms like pain, anorexia, dyspnea, fatigue and behavioral changes among others, are associated to a greater deterioration in critical diseases at the End Of Life (EOL) scenario. There is a lack of evidence regarding the analysis undertaken that leads to improvements in medical outcomes within this population, especially in the use of opioids. Methodology: The work undergone is a case series of pediatric patients from three hospitals third and fourth level of complexity in Bogota. Objective: To describe the characteristics of palliative care intervention schemes, and to describe the evolution of the symptoms of pediatric patients within the last 24 hours before their deaths in three health institutions. This group of patients, between 1 month and 17 years old who had the diagnosis of a chronic disease. A secondary objective, is to lay the foundations and to generate hypothesis related to the health care of this population for future works regarding the expected evolution of the symptoms associated to different schemes of symptom management.
