title: [Use of therapeutic hypothermia in sudden unexpected postnatal collapse].
abstract: Sudden postnatal collapse of a full-term newborn is uncommon but may result in severe consequences: these include death; epilepsy; and motor, cognitive, or sensory impairment. Most authors suggest applying a therapeutic hypothermia approach when a previously healthy newborn develops moderate or severe encephalopathy after a sudden postnatal collapse occurring within the first hours or days after birth. However, this technique has still not been validated by randomized trials. Only a few cases have been reported in the literature. This article describes five apparently healthy newborns, born between 2007 and 2012, who suffered moderate to severe encephalopathy following a postnatal collapse on their first day of life. It describes their clinical history as well as their treatment and follow-up. The article focuses on the implementation of hypothermia in this indication and its limitations. Two newborns underwent classic therapeutic hypothermia, two others underwent temperature regulation (one at 34.5 °C, the other one for only 15 h because she quickly improved). One newborn, with severe pulmonary arterial hypertension, did not receive therapeutic hypothermia. Two newborns died (one had classic hypothermia and the other hypothermia at 34.5 °C), the outcome of the three survivors at three years, 18 months, and 15 months is good with only transient postural anomalies. Follow-up must be continued to assess their cognitive development and particularly their memorization processes. Additional research and centralization of the cases is required to evaluate the feasibility, safety, and benefits of therapeutic hypothermia in this situation.
