Risks and Benefits of Swaddling Healthy Infants: An Integrative Review.

Area of Science:

• Pediatrics
• Neonatal Care
• Infant Sleep and Development

Background:

• Swaddling, an ancient practice, is widely used for infants.
• Concerns exist regarding the safety and potential risks associated with swaddling.

Purpose of the Study:

• To synthesize current evidence on the risks and benefits of swaddling healthy-term, near-term, and older infants.
• To update and expand upon previous systematic reviews of swaddling practices.

Main Methods:

• Comprehensive literature searches of MEDLINE and CINAHL databases (1960-2016).
• Review of retrieved articles and citation lists for additional relevant studies.
• Integration of older references and supporting literature for contextual understanding.

Main Results:

• Swaddling effectively calms infants and promotes sleep, comparable to other non-pharmacological methods for pain management.
• Potential slight risk of sudden infant death syndrome (SIDS) with supine swaddling, though confounding factors are unclear.
• Tight hip swaddling is strongly linked to developmental dysplasia of the hip; swaddling does not negatively impact long-term breastfeeding.
• Further research is needed on swaddling's effects on infant pain, vital signs, arousal, and potential links to vitamin D deficiency and respiratory infections.

Conclusions:

• The existing research base is limited by small study numbers and few randomized controlled trials.
• With precautions like secure swaddling, avoiding overheating, supine positioning, and discontinuing upon signs of rolling, swaddling poses minimal risk.
• Healthcare professionals should guide caregivers on evidence-based swaddling techniques to promote informed decision-making.
