PACO QUISBERT, Ledy Jhobana  y  ZARATE DE CALDERON, Eunice. Manual extraction of maternal milk for the maintenance of lactation. Cuad. - Hosp. Clín. [online]. 2009, vol.54, n.2, pp.90-91. ISSN 1562-6776.

Objectives. To determine through the manual extraction, the volumes of colostrum, transition milk and mature maternal milk produced by premature children's mothers, and to measure the increase in these children's weight nourished exclusively with mature maternal milk using orogastric tube. Material and methods. A longitudinal study, carried out in the Service of Neonatology at the "Hospital de la Mujer", in the city of La Paz. Twelve mothers and their premature sons were enrolled, and an inquiry with socio-demographic variables was applied. The maternal production of milk by manual extraction and a daily increase in the premature children's weight nourished exclusively with mature maternal milk using orogastrictube was registered. Results. Mothers produce through manual extraction an average of 71 ml/day (+/- 41.6 SD) of colostrum between 1 to 4 days; transition milk of 207 ml/day (+/- 81.9 SD) between 5 to 10 days, and mature milk of 333 ml/day (+/-105.1 SD) between 11 to 17 days. The mothers of children who are Very low birth weight (VLBW) produce a larger volume of colostrum, transition milk and mature milk. The volume of mature milk produced is larger in mothers of children who are Small for gestational age (SGA) in comparison to mothers of children who are Appropriate for gestational age (AGA). The children included in this study were nourished exclusively from maternal milk, from them 83.3% presented an adequate increase in weight. The average increase in weight from the tenth day to the seventeenth day oscillates between 18 and 40 grams per day. Conclusions. The manual extraction of mother's milk allows for delayed suckle, giving volumes superior to the requirements of the lactant. These findings are important for nutritional education, and are a favorable alternative for mothers of premature children, or mothers who are studying, working or cannot suckle for any other reason.
