Study Notes
General Information
- Sudden Infant Death Syndrome (SIDS) is the unexplained death of an infant under 1 year after comprehensive investigation, including autopsy and scene examination.
- Post-mortem exams can clarify approximately 20% of sudden death cases.
- SIDS incidence in the US has decreased to less than 1 in 1000 live births over the last 15 years, stabilizing after an initial decline.
- The "Back to Sleep" campaign significantly contributed to reducing SIDS, which previously affected 2 infants per 1000 births.
- There is a rising incidence of Sudden Unexpected Deaths in Infancy (SUDI) linked to unsafe sleeping practices.
Epidemiology
- SIDS deaths peak between 2 and 4 months of age, primarily occurring between midnight and 8 am during sleep.
- Key commonalities among SIDS cases are age and sleep patterns.
- Higher occurrence noted in ethnic/racial minorities and socioeconomically disadvantaged groups.
- A significant racial disparity exists in sleep positioning practices, contributing to SIDS rate differences among black and white infants.
- Males are more affected, with a 3:2 male-to-female ratio commonly observed.
- Identified risk factors include low birth weight, maternal drug use or teenage motherhood, multiple births, crowded living conditions, maternal smoking, and SIDS family history.
Pathogenesis
- Pathological findings most often include intrathoracic petechiae and respiratory tract inflammation.
- Less common findings may suggest chronic hypoxia prior to death, including brainstem gliosis and increased peri-adrenal brown fat.
Mechanism
- The exact mechanisms leading to SIDS are still unclear, with possible reasons including cessation of breathing or cardiac issues.
- Current theories focus on brainstem development delays impacting arousal responses.
- Mild upper respiratory symptoms before death are noted in some cases, with victims having seen a doctor shortly before passing.
Prevention
- The American Academy of Pediatrics has promoted SIDS education and prevention measures since 1994, targeting modifiable risk factors like sleeping positions and maternal smoking.
- Prone sleeping and side positions increase SIDS risk, while supine positioning is considered safer.
- Maternal smoking, particularly during pregnancy, elevates SIDS risk.
- Pacifier use and breastfeeding are associated with reduced SIDS risk.
- Recent trends indicate unsafe sleep environments contribute to accidental suffocation and asphyxia.
Role of Healthcare Providers
- Healthcare providers play a crucial role in educating parents about SIDS risk factors.
- Routine screening for SIDS risk factors in infants should be conducted, considering child care settings.
American Academy of Pediatrics Recommendations for SIDS Risk Reduction
- Promote supine sleeping position ("Back to Sleep").
- Use a firm mattress designed for infant sleep and eliminate pillows or loose bedding from the crib.
- Parents should share a room with the infant, without co-sleeping.
- Avoid smoking during and after pregnancy, fostering a smoke-free nursery.
- Consider pacifier use during naps and bedtime.
- Prevent overheating or overwrapping of infants, and avoid head coverings.
- Do not use devices advertised to minimize SIDS risk or home monitors as preventive strategies.
- Encourage tummy time while infants are awake to support development.
