Principles of Lactation Management, August 2005, Austin, Texas. p. 111-119. Technical Abstract: This powerpoint presentation summaries physiology of lactation and the impact of a variety of clinical practices on lactation from delivery through weaning. Factors that inhibit lactogenesis stage II are explained, including retained placenta, excess blood loss during delivery, and hypoplastic breast tissue. The role of oxytocin in stimulating milk ejection and the role of prolactin in stimulating production of milk proteins are described visually. The impact of specific clinical practices on the onset and maintenance of milk production are explained, including early mother-infant contact, skin to skin contact, restricted time feeding times, frequency of breast emptying, use of supplemental bottles, provision of supplemental fluids and solids, and mechanical milk expression.
