Review question
Does the use of infant pacifiers (dummies) reduce the risk of sudden infant death syndrome?
Background
Sudden unexpected death of an infant generally occurs during sleep from birth to one year of age but mainly occurs between one and four months of age. Despite the success of several prevention campaigns, sudden infant death syndrome remains a leading cause of infant mortality (death). A variety of factors have been identified as increasing the risk of sudden infant death syndrome such as male sex, preterm (before the due date) birth, overheating, exposure to cigarette smoke, and infants lying on their stomachs. Pacifier use has been proposed as a non-invasive intervention to reduce the risk of SIDS. This review was undertaken to examine whether infant pacifiers can reduce the risk of SIDS.
Study characteristics
We searched medical databases for clinical trials of SIDS in infants born at their due date or earlier (less than 37 weeks of pregnancy) or with low birth weight (less than 2500 g) using pacifiers or not using pacifiers up to one year of age. We found no well-designed clinical trials meeting our inclusion criteria.
Results
No well-designed clinical trials met our inclusion criteria.

Wprowadzenie
Sudden infant death syndrome (SIDS) has been most recently defined as the sudden unexpected death of an infant less than one year of age, with onset of the fatal episode apparently occurring during sleep, that remains unexplained after a thorough investigation, including the performance of a complete autopsy and a review of the circumstances of death and clinical history. Despite the success of several prevention campaigns, SIDS remains a leading cause of infant mortality. In 1994, a 'triple risk model' for SIDS was proposed that described SIDS as an event that results from the intersection of three factors: a vulnerable infant; a critical development period in homeostatic control (age related); and an exogenous stressor. The association between pacifier (dummy) use and reduced incidence of SIDS has been shown in epidemiological studies since the early 1990s. Pacifier use, given its low cost, might be a cost-effective intervention for SIDS prevention if it is confirmed effective in randomised controlled trials.
Cele
To determine whether the use of pacifiers during sleep versus no pacifier during sleep reduces the risk of SIDS.
Metody wyszukiwania badań
We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed, Embase, and CINAHL to 16 March 2016. We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.
Kryteria doboru badań
Published and unpublished controlled trials using random and quasi-random allocations of infants born at term and at preterm (less than 37 weeks' gestation) or with low birth weight (< 2500 g). Infants must have been randomised by one month' postmenstrual age. We planned to include studies reported only by abstracts, and cluster and cross-over randomised trials.
Zbieranie i analiza danych
Two review authors independently reviewed studies from searches. We found no eligible studies.
Główne wyniki
We identified no randomised controlled trials examining infant pacifiers for reduction in risk of SIDS.
Wnioski autorów
We found no randomised control trial evidence on which to support or refute the use of pacifiers for the prevention of SIDS.
