[Use of pacifiers and breastfeeding]. / Uso del chupete y lactancia materna.

Pacifiers are widely used in developed societies. They are used for soothing infants, reducing their stress and pain during procedures and to help them sleep. The use of pacifiers has been associated, however, with a shorter duration and exclusivity of breastfeeding, with higher rates of otitis media and dental problems, as well as a higher risk of accidents during infancy. Recent studies have also described a relationship between pacifier use and SIDS, especially when used during infant́s sleep. Other described benefits are analgesia and stimulation of non-nutritive sucking in preterm and term infants. There is, at present, wide debate and controversy on whether or not to recommend its use; thus it seems important for professionals and parents to be aware of the risks and benefits associated to its use, particularly related to breastfeeding. Due to the existing controversy of scientific findings, the Committee on Breastfeeding of the Spanish Paediatrics Society, publishes this review, trying to summarise present evidence with the objective of, after analysing scientific results and recommendations, making recommendations regarding the use of the pacifier in the breastfed infant.

[A descriptive study of perinatal asphyxia and its sequelae]. / Estudio descriptivo de la asfixia perinatal y sus secuelas.

INTRODUCTION: Perinatal asphyxia is a potential cause of brain injury that can produce some alterations on the neurologic development of the newborn. On the last years most part of the investigation have been focused on the physiopathology of the perinatal asphyxia, but correlation between asphyxia and brain damage is not well defined. PATIENTS AND METHODS: A retrospective study was made of the patients with the diagnosis of perinatal asphyxia born at the General Hospital of Segovia during a period of ten years (1992-2001). We took data about gestation, birth, neonatal period and follow-up period from their clinical histories. RESULTS: Over this period of ten years 703 cases of perinatal asphyxia have been diagnosed, supposing this an incidence of 7,2 cases of each 100 newborns. 116 of these newborns present risk factors of brain damage and were followed at least two years. 53 of the 116 newborns (45%) present evidence of hypoxic-ischemic encephalopathy on neonatal period. During the period of two years, 42 of the asphyxiated infants follow up (36%) present neurologic sequelae, being psychomotor retardation the most common. CONCLUSION: For a correct interpretation of the relationship between perinatal asphyxia and neurologic sequelae we have to analyze all of the perinatal data and discard any other possible aetiology or pathogenic mechanism.
