Introduction: perinatal asphyxia and its consequence, the hypoxic-ischemic encephalopathy are responsible for the high level of morbidity (and mortality) in neonates and children. The development of a comprehensive neuroprotective strategy that includes therapeutic hypothermia, aims to mitigate its effects. Objective: our goal is to achieve the implementation of a global neuroprotection protocol in a newborn service. Methodology: monocentric, retrospective and observational study of a cohort of patients that received controlled hypothermia between 2011 and 2014 and were hospitalized in the Pereira Rossell Hospital Center (CHPR). The protocol included the training of the nursing staff and the medical team as well as the necessary technological adaptation. Results: 20 patients matched the inclusion criteria, 2/20 did not fulfill the 72 hours needed for the cooling by alteration of the coagulation and active refractory bleeding and 4/20 died. The active cooling started with a mean of 60 minutes, and the goal of 33,5°C was reached with a mean of 2 hours. Both hyperoxia and hypocapnia were observed in the initial assistance and metabolic acidosis, hyponatremia and hyperglicemia were also observed during the maintenance period, as well as over-diagnosis of convulsive crisis. Coagulation disorders were the most severe side effects. Conclusion: the implementation of a protocol of assistance of the asphyctic newborn with mild-severe HIE allows the introduction of controlled hypothermia as a strategy to reduce mortality, placing it on the levels observed in higher-income countries. It shows the need of improving the initial assistance, of controlling alterations in the acid-base metabolism, glucidic metabolism, sodium metabolism and above all, of the alterations of the coagulation as the associated phenomena of greatest severity.
