Methods of milk expression for lactating women

Area of Science:

• Perinatal health
• Lactation science
• Infant nutrition

Background:

• Breastfeeding is crucial for infant and maternal health.
• Effective methods for expressing breast milk are not fully understood.
• Not all infants can breastfeed directly.

Purpose of the Study:

• To evaluate the acceptability, effectiveness, safety, and cost of various milk expression methods.
• To assess milk composition and bacterial contamination associated with different expression techniques.
• To compare hand expression with manual, battery, and electric pumps.

Main Methods:

• Systematic review of randomized and quasi-randomized controlled trials.
• Inclusion of cross-over trials initiated at least 28 days postpartum.
• Data extraction and quality assessment by two independent authors.

Main Results:

• Electric and foot-powered pumps expressed significantly more milk than hand expression over six days.
• A relaxation tape increased milk volume per expression session.
• Simultaneous pumping was more time-efficient than sequential pumping.

Conclusions:

• Electric or foot-powered pumps may be more effective for milk expression than hand expression.
• Relaxation techniques and simultaneous pumping can enhance milk expression.
• Further research is needed with larger sample sizes and comprehensive reporting.
