Comparison between levels of prolactin of mother in relactation and exclusive breast feeding mothers

摘要

Not experimental, prospective, comparative, and longitudinal study conducted in order to compare the levels of prolactin in 15 mothers (study group) with more than two weeks of having suspended the breastfeeding, and trained to relactate according to the method recommended by World Health Organization: nipple and breast stimulation, technique of dripping and drip and mechanical and manual removal, and 25mothers (control group) that breastfeeding exclusively, whose children less than six months, were hospitalized with various diseases, in the Division of Pediatric of University Hospital in Maracaibo, from November 2010 to October 2011. The mothers had between 15 and 25 years of age in both groups (p = 0.58), the main cause of the abandonment of breastfeeding was insufficient milk production (46.67%). The time of occurrence of milk secretion was 6+1.60 days. Prolactin levels in the study group mothers in the first 24 hours of admission was 35.58+18.04 ng/ml, and in the control group 129.83+35.01 ng/ml, statistically significant (p=0.01). Initiated the milk secretion was 121.20+16.90 ng/ml, statistically significant (p = 0.01 compared to base line study group, but when was compared to the control group was not statistically significant (p = 0.13). It concludes that in this group of mothers who left nursing, once started relactation had significantly higher prolactin levels, similar to the levels in mothers exclusively breastfeeding.
