[Pain management in Neonatology].

The recognition of the existence of pain in infants hospitalized in the Neonatal Intensive Care Units makes it necessary to reach consensus on prevention, assessment and treatment strategies. Acute pain produces adverse changes in the short term and chronic pain alters the response systems to stress and impacts on neurodevelopment. The objective of this pain management agreement is to unify criteria of attention of these patients in different situations that generate pain and stress that they face during their hospitalization. There are validated scales to assess pain and guide appropriate strategies for its approach that include measures of comprehensive or nonpharmacological care and pharmacological care that we will review.
